100% Customer Satisfaction!
You paid a premium for a Trex, TimberTech, or PVC deck so it would stay beautiful. Then the black spots showed up anyway. Mr-Suds cleans composite decking across Newington with gentle, manufacturer-safe methods, no warranty-voiding pressure, no scratched capping.
Composite decking earned its reputation. No staining, no sealing, no splinters. But the brochure said low maintenance, and somewhere along the way we all heard “no maintenance.”
The deck itself knows better. Connecticut humidity feeds mildew on any outdoor surface, capped or not. Pollen settles into the grain texture every spring. Shade from the house keeps half the boards damp until noon.
So the black spots arrive, then the gray film, then the slippery patch by the steps. None of it means your deck is failing. It means the surface is due for a proper cleaning, the kind that respects what composite is made of.
Small dark speckles that multiply every season, usually worst in shade. They live in the surface texture, so casual scrubbing spreads them around more than it removes them. We treat them at the source.
An algae film loves the same damp corners your deck furniture shades. It is a slip hazard first and an eyesore second. We remove it at the root.
By June, Newington's tree cover has dusted every deck in town. The film dulls the color you chose so carefully. One wash and the original tone is back.
Cooking spatter bonds to composite capping and laughs at a garden hose. The right detergent, the right dwell time, gone.
Sometimes it is buildup, sometimes early-generation boards wearing their age. We inspect honestly and tell you which one you have before any water flies.
Wet leaves sitting through fall leave brown shadows behind. These respond well to targeted treatment rather than more pressure.
Here is the part most homeowners find out too late. Composite boards are wood fiber and polymer wrapped in a thin protective capping. That capping is the whole defense system. High-pressure blasting can scratch it, open the texture, and give mold a permanent home inside the board.
It gets worse. Trex specifically warns against pressure washing early-generation decking, and damage caused by a pressure washer can void your warranty coverage for that condition. A twenty-thousand-dollar deck is not the place to gamble with a rental machine.
Our method is built around that reality. Low pressure, a cleaning solution matched to composite surfaces, patient dwell time, and a gentle rinse. The growth dies at the root. The capping never takes a hit.
(If your deck is wood, the process is different. See our deck and patio cleaning service for that.)
Boards, railings, stairs, skirting, and post caps. The whole structure, not just the walking surface.
We start with an inspection, because Trex Transcend and a fifteen-year-old first-generation board should not be treated the same way. Then the solution goes on, works into the texture, and rinses off along with the mold, algae, and grime it dissolved.
Furniture gets moved and replaced. Plants around the deck get pre-wet and rinsed. And Roman walks the finished deck with you before packing up.

Tell us the decking brand if you know it. We check board generation and condition, then give you an exact price.
Manufacturer-safe pressure, composite-specific solution, full structure cleaned.
Every board checked, every question answered, before we leave.
We clean composite and PVC decks throughout Newington, from Maple Hill and Newington Junction to homes near Mill Pond Park and the Cedar Mountain side of town. Composite decks here spend much of the day under mature tree shade, which is exactly the environment where mildew moves in first. If your deck faces north or sits under oaks, you have probably already seen the spots.
We also serve Wethersfield, Rocky Hill, Berlin, and West Hartford.
The recent PVC deck in the photo above came back looking close to new, and the boards were never put at risk to get there.
“Mr. SUDS did a great job on our exterior and deck. Both came out looking like new,” wrote David L. in his Google review.
Our methods are chosen to protect your deck surface, not test it.
In writing, before we start.
Roman quotes it, cleans it, and answers for it. A 5.0 Google rating says the system works.
Twelve real reviews from local customers, each one answered personally by the owner.
“Mr. SUDS did a great job on our exterior and deck. Both came out looking like new. He was also very pleasant to deal with.”
“Roman provides high quality service and is detail oriented. Roman is passionate about his work, and customer satisfaction!”
“He took the time to clean every detail, and you can tell he really cares about the quality of his work.”
The black spots are not a verdict on your deck. They are a maintenance call, and answering it costs a fraction of what the deck did. Free quote, manufacturer-safe process, owner-done work.

Technically yes, within strict manufacturer limits, but it is the riskiest way to clean one. High pressure can scratch the protective capping and open the surface to permanent mold intrusion. We soft wash composite instead: low pressure plus a cleaning solution that does the work safely.
Proper cleaning will not. Improper pressure washing can. Trex warns against pressure washers on early-generation boards, and damage from one is not covered. Our low-pressure, manufacturer-aware method is designed to stay well inside the safe zone.
The spots are mold living in the surface texture, so they need to be killed, not just blasted. Our solution penetrates the texture, breaks down the growth at its root, and rinses clean. The spots stay gone far longer than with scrubbing or plain rinsing.
Straight household bleach applied carelessly can discolor some composite surfaces and harm surrounding plants. We use professional solutions at composite-safe concentrations, with landscaping pre-wet and rinsed. The chemistry matters as much as the pressure.
Once a year suits most Newington decks, usually in spring after pollen season. Heavily shaded decks may show regrowth sooner and do better on a spring-plus-touch-up rhythm.
It depends on deck size, railing length, and buildup level. A quote is free, exact, and final. Many customers bundle the deck with a house wash or fence cleaning in the same visit.
The same day. Once the deck is rinsed and surface-dry, usually within a few hours, furniture can go back and feet can follow.
