Dover's Exteriors Cleaned Right

Dover is one of New Hampshire's oldest cities, and that history shows up in the housing stock. Colonial homes, Victorian-era siding, brick mill buildings converted into apartments — older materials that need the right cleaning approach, not just the most powerful one. We're Splash Pressure Washing, and we handle residential and commercial exterior cleaning throughout Dover and the surrounding Seacoast region. Homeowners on Back River Road, landlords managing rental properties near UNH's campus in Durham next door, business owners along Central Avenue — we do the work properly for all of them.

Dover sits on the Cocheco River, and that tidal river humidity is something most homeowners don't think about until the algae is already on their siding. Add in the salt air that drifts in from the coast, New Hampshire's freeze-thaw winters, and the exhaust and road grime that accumulates on properties near Dover's busier corridors — and exterior surfaces here take a consistent beating. The buildup is quiet at first. A grey tint on the siding. A streak on the roof. A slippery walkway. Then one day it's a problem that's harder and more expensive to fix than it would have been a season ago.

That's the cycle we break. We soft-wash siding, roofs, and wood surfaces using low pressure and biodegradable solutions — the right method for Dover's older homes that can't handle a high-pressure wand without real damage. For driveways, walkways, and concrete, we use pressure washing where it's appropriate. We've completed 1,000+ exterior cleaning jobs across New Hampshire and we know what works here. Give us a call — most Dover jobs are quoted and booked within 48 hours.

Why Dover Homes & Businesses Need Regular Exterior Cleaning

Dover doesn't have a lake at its doorstep — it has the Cocheco River, Great Bay a few miles south, and the kind of persistent coastal humidity that rolls in off the Seacoast and doesn't fully leave. That damp air is what feeds algae and mildew on siding, moss on roofing, and the biological staining that works its way into older Dover homes faster than most people expect. A lot of the housing stock here is older — colonial, Victorian, century-old wood and brick that looks great when maintained and starts deteriorating quietly when it isn't.

Road salt is a bigger problem in Dover than in the quieter Lakes Region towns. Central Avenue, Sixth Street, and the neighborhoods around the traffic circles take heavy winter treatment — and that salt doesn't just stay on the road. It lands on driveways, walkways, and lower siding panels and works into the concrete and paint through every freeze-thaw cycle from November to March. Most Dover homeowners only notice when the concrete starts cracking or the paint starts peeling at the base of the wall. By then, the damage has already compounded.

For business owners along Central Avenue or the Washington Street corridor, and for landlords managing rental properties near downtown — Dover's real estate market is active and the bar for presentation is real. A neglected exterior on a rental property means longer vacancies and lower rents. For a storefront, it's the first impression before a customer decides whether to walk in. One proper cleaning a year keeps all of that from becoming a problem you're paying more to fix later.

Splash Pressure Washing serves Dover and the surrounding Seacoast area. We use soft washing on older siding, wood, and roofing where high pressure would cause damage — and proper pressure washing on concrete driveways, walkways, and commercial surfaces that need it. Fully licensed, insured, and familiar with what New Hampshire's coastal climate does to properties specifically.

Our Services

Pressure Washing Services in Dover, NH

Dover is a city with real character — older homes, a busy downtown, and a mix of residential and commercial properties that all deal with the same thing: New Hampshire winters, Cochecho River humidity, and grime that builds up faster than most people get around to dealing with it. We handle all of it, properly, for both homeowners and businesses across Dover.

House washing service in Dover NH

House Washing

Dover has a lot of older housing stock — colonials, Victorians, and cape-style homes that have been around long enough to show what neglected siding actually looks like. The Cochecho River runs right through the city, and that tidal humidity is a constant source of mold and algae on north-facing walls and shaded siding panels. We soft-wash every exterior surface using low pressure and biodegradable solutions — nothing that forces water behind boards or strips paint from older finishes. Your home comes out clean and stays that way.

Roof cleaning service in Dover NH

Roof Cleaning

Those dark streaks spreading across Dover rooftops aren't dirt — they're gloeocapsa magma, a bacteria that feeds on the limestone filler in asphalt shingles. It's extremely common in humid Seacoast cities like Dover, and most roofing manufacturers will void a warranty if the growth is left untreated long enough. We use the ARMA-recommended soft wash method — low pressure, correct treatment solution — that kills it at the root without damaging a single shingle granule. The streaks are gone, and they stay gone for years.

Window cleaning service in Dover NH

Window Cleaning

Dover's older homes often have original wood-framed windows that haven't seen a proper clean in years — hard water deposits, city dust off Central Avenue, and winter grime that builds up in the corners and frames. We clean residential windows streak-free inside and out, taking care around older frames and seals. It's one of those jobs that makes an immediate difference to how a house looks and feels from both sides of the glass.

Gutter cleaning service in Dover NH

Gutter Cleaning

Dover gets heavy leaf drop from the mature trees lining its older residential streets — Locust Street, Tolend Road, the neighborhoods off Sixth Street — and by mid-fall those gutters are working hard. Blocked gutters going into a New Hampshire winter mean ice dams, and ice dams mean water sitting against fascia boards and rooflines for months. We clean everything out before the freeze, test every downspout, and make sure water is draining away from your foundation before the cold locks in.

Deck and pool deck cleaning in Dover NH

Deck & Pool Deck

Dover decks go through a full New Hampshire winter and come out the other side looking it. The freeze-thaw cycle works into wood grain and composite surfaces, and the moisture off the river valley keeps things damp long enough for algae and mildew to take hold by early spring. We clean wood, composite, and stone deck surfaces so they're safe to walk on and ready to use when the weather finally cooperates — not something you have to tackle yourself before your first cookout of the year.

Walkway cleaning service in Dover NH

Walkway Cleaning

Road salt is a fact of life on Dover streets and driveways — it keeps things safe in winter but leaves concrete and paver surfaces stained and pitted by spring. Add the river humidity that keeps shaded walkways damp through the warmer months, and algae establishes itself fast. We pressure wash driveways, front paths, and paver walkways so the approach to your home looks presentable and the surface is safe for everyone using it — including kids and elderly family members who shouldn't be navigating slick pavers.

Fence cleaning service in Dover NH

Fence Cleaning

Dover's residential neighborhoods have a lot of older wood fencing that's seen enough winters to look like it. But what looks like age is often just surface mold, oxidation, and grime — and most of it comes off cleanly with the right treatment. We restore wood and vinyl fences without using pressure levels that damage the surface or force water into joints. In most cases, a fence that looks like it needs replacing just needs a proper clean first.

Patio cleaning service in Dover NH

Patio Cleaning

Dover summers are good but short — you want every week of them. A patio that's carrying winter staining, algae, or leaf residue from the previous fall is a project you don't want sitting between you and actually enjoying your outdoor space. We wash concrete, brick, flagstone, and stamped patio surfaces so everything is clean and usable from the first decent weekend of the season. One morning's work, whole summer's worth of use.

Commercial building washing in Dover NH

Building Washing

Dover's downtown along Central Avenue and Washington Street has seen serious investment over the last decade — new restaurants, retail, offices, and mixed-use buildings that all share the same problem: exterior surfaces that accumulate road exhaust, biological growth, and winter grime faster than they get cleaned. We soft-wash commercial building exteriors using methods matched to brick, stucco, metal panel, and EIFS — so the facade gets a proper clean without streaking, etching, or damage to window seals that your tenants will notice before you do.

Parking lot and garage cleaning in Dover NH

Parking Lot & Garage Cleaning

Dover is a commuter city — a lot of people park here daily, and commercial lots and garages around the Garrison City Business Park and the Spaulding Turnpike corridor take constant wear. Road salt and sand tracked in through winter embeds into parking surfaces and starts breaking down the pavement underneath if it's not cleaned out. We pressure wash parking lots and garage floors on a schedule that works around your operation — typically overnight or early morning — so the lot is clean when your first customers or tenants arrive.

Apartment complex exterior cleaning in Dover NH

Apartment Complex Cleaning

Dover's rental market has grown considerably — UNH students, young professionals working in Portsmouth and Manchester, and long-term residents all competing for a limited stock of apartments. In that market, exterior condition matters more than landlords often realize until a unit sits vacant. We handle the full exterior footprint of multifamily buildings — siding, stairwells, walkways, and parking areas — working around tenants' schedules and keeping disruption to a minimum while the building gets back to a standard that actually helps you lease faster.

Storefront and awning cleaning in Dover NH

Storefront & Awning Cleaning

Central Avenue has become one of the better downtown strips in the Seacoast — good restaurants, independent retail, and foot traffic that actually converts. A dirty storefront or a mildewed awning sends a message before anyone reads your sign. We clean storefronts and awnings without damaging paint, fabric, or seals — removing the exhaust residue, mildew, and winter buildup that accumulates on every street-facing surface in a city like Dover. Work scheduled around your hours so there's no disruption to the day.

Multifamily property exterior cleaning in Dover NH

Multifamily Property Cleaning

Condo developments and townhome communities across Dover — from the newer builds off Whittier Falls Way to established complexes near Silver Street — need consistent exterior maintenance to hold their value in a market where buyers are paying attention to condition. We cover the full property: siding, walkways, driveways, and shared outdoor areas, keeping HOA boards and property managers ahead of issues rather than reacting to them after a tenant complaint or inspection.

Learn More
Drive-through cleaning in Dover NH

Drive-Through Cleaning

Dover has a solid concentration of drive-through businesses along the Sixth Street and Rt. 108 corridors — and those lanes build up grease, oil, and food residue into the pavement faster than most operators get around to addressing it. It becomes a hygiene issue before it becomes a visible one. We clean the full lane and apron surface on a schedule that runs around your operation — early morning before opening works well for most Dover locations — so the lane is clean and presentable every day of the week.

Our Process

How Pressure Washing Works
in Dover, NH

Dover is a busy city — older homes, tight neighborhoods, commercial strips, and Cochecho River humidity that does a number on exteriors year-round. Here's exactly what working with us looks like, from your first call to a clean property.

STEP 01

Tell Us What
You're Working With

Call or fill out the form. Tell us what's going on — green siding, a stained driveway, black streaks across the roof — and roughly when works for you. Dover properties vary a lot, from older colonials in the Henry Law Avenue area to newer builds further out. The more you tell us upfront, the more accurate the number we give you.

STEP 02

We Assess and Give You a Real Price

We look at the surfaces, the staining, any tricky access points — then give you a straight quote. No ranges, no estimates that climb once we're on the job. Dover has a mix of historic brick, vinyl, and wood siding across the city. We know what each one needs and we price accordingly. What we say is what you pay.

STEP 03

We Show Up and Get It Done

Dover's older housing stock needs the right approach — high pressure on historic siding or wood trim causes real damage. We soft-wash what needs it, pressure wash the surfaces that can handle it — driveways, concrete walkways, brick pavers — and work around your landscaping so nothing gets disturbed. Most residential jobs in Dover are done and dusted in a few hours.

STEP 04

You Sign Off, Then You Pay

Before we load up the van, we walk the property with you — or send you photos if you weren't home. If there's a spot that needs another pass, we do it on the spot. You pay when you're happy with what you're looking at. Not before.

Why Choose Us

Why Dover Homeowners Choose Splash Pressure Washing

Dover is one of the fastest-growing cities in New Hampshire — which means more people investing seriously in their homes. Property values here are real. A dirty exterior isn't just an eyesore; it's quietly working against what your home is worth. We fix that.

Customer Service

Dover People Are Busy — We Work Around That

Dover has a lot of working professionals and young families who don't have time to wait around for a contractor. We give you a confirmed arrival window, show up in it, and get the job done without you needing to rearrange your day. You shouldn't have to take time off work to get your driveway cleaned.

Safe Methods

We Know What Dover's Climate Does to Exteriors

Dover sits in the NH Seacoast — salt air from the coast, moisture off the Cochecho River running through downtown, and hard winters with real road salt exposure on Central Avenue and the surrounding neighborhoods. That combination drives mold, algae, and oxidation into siding and concrete faster than inland towns. We use the right cleaning method for each surface so the results actually hold.

Licensed and Insured

Fully Insured — $2 Million Per Job

Dover home values are among the highest in the Seacoast. The last thing you need is an uninsured contractor on your property when something goes sideways. We carry $2 million in liability coverage on every single job. It's the baseline for doing this work professionally — and we'd encourage you to ask any company you're considering if they carry the same.

Top Rated

Reviews From Real Dover Customers

Not reviews from across the state. Reviews from homeowners in Garrison Woods, off Henry Law Avenue, along Dover Point Road — people who found us, hired us, and came back the following year. That's the kind of local reputation that actually means something when you're deciding who to let on your property.

Transparent Pricing

Flat Quotes — What We Say Is What You Pay

We give you a firm price before any work starts. No "starting from" numbers, no scope creep that quietly inflates the invoice. Dover homeowners are savvy — they've dealt with enough contractors to know the difference between a quote and a guess. Ours is a quote.

Hassle Free

Clean Results With Zero Back-and-Forth

We document the job with before-and-after photos and send them when we're finished. You don't need to hover, check in, or follow up. The work either meets the standard we agreed on — or we come back and fix it. That's the guarantee, and we've never had to argue about it with a Dover customer.

Benefits of Pressure Washing
in Dover, NH

Dover gets hit from both sides — salt air rolling in off the Cochecho River, heavy winters, and the kind of damp springs that turn siding green before most homeowners notice. Regular pressure washing in Dover isn't just about looks. It's about keeping your property from wearing out faster than it should.

Professional pressure washing a home exterior in Dover NH
01

Your Siding Actually Lasts Longer

Dover's moisture and humidity give algae and mildew the perfect conditions to settle into your siding every season. Left alone, that biological growth doesn't just stain — it breaks down the material underneath. Cleaning it off regularly is cheaper than replacing panels early.

02

Your Roof Stops Losing Years

Those black streaks spreading across Dover rooftops aren't dirt — it's a bacteria called gloeocapsa magma that feeds on asphalt shingles. It shortens the life of your roof quietly, season after season. Soft washing removes it without damaging the shingles, buying your roof years it would otherwise lose.

03

Driveways and Walkways Stay Safe

Dover winters leave road salt, oil, and organic staining embedded in concrete and pavers by spring. That buildup makes surfaces slippery and speeds up surface cracking from freeze-thaw cycles. A proper pressure wash each year keeps them clean, safe, and holding up the way they're supposed to.

04

Your Property Holds Its Valuet

Dover's real estate market is active — homes on the Cochecho waterfront and throughout the Garrison City neighborhoods move based on presentation as much as anything else. A clean exterior tells buyers, tenants, and neighbours that the property is maintained. A neglected one does the opposite, and it shows up in appraisals.

Pressure Washing FAQs

Answers to the questions Dover homeowners and property owners ask us most.

Yes — we serve Dover and the surrounding Seacoast New Hampshire area. Whether you're in South Dover, the North End, near the Cocheco River waterfront, or out toward Dover Point, we come to you. Dover is one of the fastest-growing cities in New Hampshire, and we work with a mix of longtime homeowners, new residents, and landlords managing rental properties across the city.

Serving Dover and the Seacoast NH area — residential and commercial

Dover sits in the Seacoast region of New Hampshire, which means it gets a specific combination of inland humidity and coastal salt air moving in from the Atlantic. That salt air is particularly aggressive — it doesn't just sit on surfaces, it works into porous materials like concrete, brick, and wood siding and accelerates the growth of algae, mold, and mildew from the inside out. Homes near the Cocheco River and Dover Point deal with tidal humidity on top of that. It's not neglect — it's just what Seacoast NH does to exterior surfaces if you don't stay ahead of it.

Coastal salt air and tidal humidity make Dover one of the harder Seacoast environments on home exteriors

It depends on the size of the property, what surfaces need cleaning, and how much buildup has accumulated. A house wash on a single-family home in South Dover is going to be priced differently from a full exterior clean on a larger colonial near the North End or a multifamily rental property. Dover's older housing stock — particularly the mill-era brick buildings and historic homes near downtown — sometimes needs a more careful approach than newer construction, and we price that honestly. You get a clear number upfront. No surprises on the invoice.

Straight quotes for every Dover job — what we say is what you pay

This is a real concern in Dover, and the right one to have. High-pressure washing on older brick, mortar joints, and historic wood trim can cause serious damage — it erodes mortar, forces water behind clapboards, and strips paint that's protecting wood underneath. Soft washing uses low pressure with a biodegradable cleaning solution that lifts the grime and kills biological growth without putting any stress on older materials. Dover has some genuinely beautiful historic properties — we treat them accordingly. If you're unsure whether your home's exterior can handle cleaning, ask us before we start. That conversation costs nothing.

Low-pressure soft wash — safe for Dover's older brick, mortar, and historic wood surfaces

Spring is the busiest window — once the ground thaws and temperatures hold above 50°F consistently. For Dover homeowners, a spring clean makes the most sense right after winter: road salt residue has had all season to sit on driveways and foundations, and the mold that established itself through the damp fall months is ready to be dealt with before it sets deeper. A late-fall wash before winter is also worth doing — it keeps grime from sitting on surfaces through the cold months and makes spring maintenance significantly easier and cheaper.

Spring and late fall are the two best windows for Dover properties

We do — and Dover's rental market makes this a common request. The city has a large student and young professional population, strong tenant demand, and landlords who know that exterior appearance directly affects vacancy rates and what rent they can reasonably charge. We handle multifamily buildings, duplexes, and investment properties efficiently — working around tenant schedules and keeping disruption low. Whether you manage one property or several across Dover, we can set up a regular cleaning schedule that keeps things maintained without you having to chase it yourself.

Regular cleaning schedules available for Dover landlords and property managers

Yes — and this matters in Dover given how much of the city sits along or near the Cocheco River and its tributaries. We use biodegradable, phosphate-free detergents that break down before they can reach waterways, and we follow New Hampshire environmental guidelines for any work near tidal or freshwater areas. The Cocheco is a big part of what makes downtown Dover what it is — we're not going to do anything that puts that at risk. If your property is right on the water or you have specific concerns about runoff, tell us before we start and we'll plan the job accordingly.
