Green algae on the shaded side, black spotting along the railings, boards that have gone flat and grey. Mr-Suds Power Washing PROs cleans wood, composite and patio surfaces for homeowners here in Newington, using surface-appropriate pressure instead of whatever a rental machine defaults to. Free on-site estimate, flat quote, no obligation.
We clean the whole outdoor living area, not just the deck floor:
Most homes here have a deck and a patio sitting side by side, so we usually do both in one visit. It works out cheaper than booking two trips, and the property looks finished rather than half-done.
Treating it like wood is how boards get ruined. If your deck is Trex, TimberTech, Azek or similar, our composite deck cleaning page covers that method in detail.

Green algae grows fastest on the shaded and north-facing sections of a deck, where boards stay damp for days after rain and never get enough direct sun to dry properly. It is not just cosmetic. Wet algae is genuinely slick underfoot, and stair treads are where people slip.
This town has a lot of mature tree canopy, which is lovely in July and rough on a deck. Backyards on the older streets around Cedar Mountain and the Junction tend to green up first every spring.
The dark patches spreading out from the board gaps and along the railing tops. Most homeowners assume that is permanent staining in the wood. Usually it is organic growth sitting in the surface film, and it comes off.
Grey is not always age. On a lot of decks it is surface oxidation plus years of embedded dirt, pollen and biofilm, and a proper wash recovers far more colour than people expect. We have had homeowners cancel a rebuild quote after seeing what came back.
Worth knowing: much of this town’s housing stock is post-war ranches, Capes and split-levels, and a large share of those decks went up in the late eighties and nineties. Thirty-year-old pressure-treated lumber can look finished when it is really just filthy.
Wet oak and maple leaves left through the autumn leach tannin into the boards, leaving brown-black outlines shaped like the leaves themselves. Snow packs them down over winter, which makes it worse. Cleaning lifts most of it.
Moss takes hold in the joint sand between pavers, and lichen grips flagstone and bluestone hard. Both are slip hazards on a wet path, and moss in the joints eventually pushes stones out of level.

These take far less pressure than most people assume. We use a wide fan tip at a set standoff distance, because too much pressure raises the grain and leaves fuzzing and wand marks. Those marks then hold dirt, so the deck looks worse next season than it did before.
Low pressure, composite-appropriate solutions, never bleach. A scarred composite board cannot be sanded back the way wood can, so the board has to be replaced. That is the entire reason the method matters more on composite. Full detail is on our composite deck cleaning page.

We look at the surface, check the shade and drainage, and give you a flat quote before anything is booked.
Furniture, grill, planters and rugs moved off.
Beds and shrubs around the deck get pre-wetted and covered before any solution goes down. This is the step almost nobody talks about, and it is the one homeowners worry about most.
Debris off, including the packed leaf matter in the board gaps.
Applied at low pressure and given dwell time to do the work. The chemistry lifts the growth. The machine only rinses it away.
Railings, balusters and stair treads by hand. Balusters take the longest and they are the first thing a visitor notices.
Then rinse the surrounding plants and lawn down thoroughly.
We do not pack up until you have looked at it and you are happy.
Our address is 130 Dewey Ave, 06111. Not a service area we drive out to. The town we work in.
That is worth checking on any quote you get. A lot of the companies that show up for local searches are dispatching from Manchester, Southington or Middletown, and some of them route your call to a toll-free number in another state. Ask where the truck actually starts its day.
Beyond the address:
We carry Connecticut Home Improvement Contractor registration with the Department of Consumer Protection and general liability cover. Ask for proof of both. From anyone.
Earned on local properties.
The number you get at the estimate is the number on the invoice.
If a section needs another pass, it gets one while we are still there with the hoses out.
That is a real form of accountability. If I do a rushed job on Willard Avenue, I am going to hear about it at the gas station, and honestly that suits me fine. It keeps the standard where it should be.
Most decks around here land between $150 and $325, which works out to roughly $0.35 to $0.65 per square foot. A typical local deck runs 150 to 400 square feet, so that band covers the large majority of what we quote.
What moves the number:
That last one usually saves money. One trip, one setup, one water hookup.
You will not get an accurate figure over the phone, and anybody who gives you a firm one without looking is guessing. We come out, measure, look at the boards, and hand you a flat written quote. Free.
We work throughout 06111, from Newington Junction and the Willard Avenue area across to the Cedar Mountain neighbourhoods and the properties set back off the Berlin Turnpike corridor. Different parts of town have different problems: the older tree-shaded streets get algae early, while the newer open lots hold up longer between cleans.
We also serve Wethersfield, Rocky Hill, New Britain, Berlin, West Hartford, Hartford and Farmington.
If you have searched deck washing near me and mostly found companies based two towns over, that is the local market for you. When a neighbour searches power washing near me and finds us, we are usually the closest truck on the list.
We also handle composite deck cleaning for Trex and PVC boards, house washing, soft washing for siding and delicate surfaces, fence cleaning, patio and deck washing in Hartford, and roof cleaning for moss and black streaking.

Most local decks come in between $150 and $325, roughly $0.35 to $0.65 per square foot. Size is the main driver, but railings, balusters, stairs and multi-level layouts add hand-detailing time. Adding a patio to the same visit costs less than booking two separate jobs.
Once a year suits most decks in this climate, usually in spring. Shaded decks under heavy tree cover often need it more like twice a year, spring and again after autumn leaf drop. Cleaning is never permanent, since algae and mildew always come back eventually.
It can, at the wrong pressure. High pressure through a narrow tip raises the grain, leaves fuzzing and cuts visible wand marks into softer boards. We use a wide fan tip at a controlled distance and let the cleaning solution do most of the work instead.
Not with the right routine. Beds and shrubs are pre-wetted and covered before anything is applied, then rinsed down thoroughly once we finish. Dilution matters too. Problems almost always come from unprotected plants and solution left sitting rather than the products themselves.
Yes, always. Stain applied over algae, mildew or embedded dirt seals the growth underneath and peels early, so the prep work decides how long the finish lasts. The boards also need to dry fully first, typically a couple of days depending on weather.
No. Composite needs lower pressure and composite-appropriate solutions, and bleach should be avoided because it can lighten the surface unevenly. Some early-generation boards should not be pressure washed at all. Check your manufacturer’s guidance, such as the Trex care and cleaning notes.
Most residential decks are a single-visit job, finished the same day. Size, railing count and how heavily soiled the boards are all affect it. Adding a patio extends the visit but rarely turns it into a second day. We confirm timing at the estimate.
Spring is the most popular window, once the pollen has settled and before summer entertaining starts. Autumn works well too, clearing leaf and tannin staining before snow packs it in over winter. We schedule through the whole season, weather permitting.
Your deck probably is not worn out. It is dirty, and from the kitchen window those two look identical. One careful visit usually brings the colour back and takes the slip risk off the stairs.
Call for a free on-site estimate, or send a photo of the boards and we will tell you what we are seeing before we come out.
