Homes in Northwest Connecticut deal with harsh freeze-thaw cycles, heavy snowfall, and humid summer shade. If your patio sits under mature trees, damp conditions encourage moss, dark algae, and black lichen to grow fast. Using standard high-pressure wands on hardscapes often gouges softer stones or strips joint sand straight out from between pavers. We take a different approach, using balanced water temperature and calibrated pressure alongside targeted treatments to lift organic growth and deep dirt while leaving your stone structure intact.

Why Deep Washing Matters More Than Just Appearance
Slick green algae on a walkway is a fall hazard after a summer rain. Beyond safety, leaving moss and lichen alone causes real structural trouble over time. Moss roots dig into joints and hold onto moisture like a sponge. When winter temperatures drop, trapped water freezes and expands, cracking joint mortar and pushing pavers out of place. Clearing away growth early keeps your joint sand stable, protects masonry joints from splitting, and keeps outdoor areas clean for backyard get-togethers.
Interlocking Pavers
High water pressure strips paver surfaces and blasts sand right out of the joints. We use flat-surface rotary washers paired with targeted detergents to pull dirt out of textured paver faces while keeping joint sand settled where it belongs.
Bluestone, Flagstone, & Natural Fieldstone
Soft natural stones like bluestone and slate demand lower water pressure and specific cleaning formulas. We lift black lichens, leaf stains, and dark grime without flaking the face of the stone.
Poured & Stamped Concrete
Porous concrete traps dirt, oil spills, and rotting leaves inside small surface pores. Our process lifts deep stains from stamped patterns and broomed concrete, leaving pool decks and patios looking fresh.
Wood & Composite Decks
We clean natural wood decks and synthetic composite materials using low pressure and gentle detergents. This strips away gray sun damage, pollen, and green mildew without raising wood grain or scratching composite boards.
Retaining Walls, Pillars, & Stone Steps
Vertical masonry traps damp shade fast. We clear lichen and mold off retaining walls, decorative pillars, and entryway steps so your vertical stone matches your freshly cleaned flat surfaces.
Concrete & Paver Driveways
Driveways take constant wear from vehicle tires, salt, and dripping oils. We use commercial rotary cleaners to break down dark oil marks and tire scuffs across paver, concrete, and asphalt driveways.

“What a beautiful job CleanScapes did on our patio and walkway. They were efficient, provided us with a fair estimate and did great work! I will use them next time, for sure!”

“Had a huge paver patio and multiple paver walkways powerwashed and resanded with minor leveling repairs. Was probably 20 years old at least and it looks like new. Exceptional quality work and a good price to boot. I'd recommend CleanScapes without hesitation”
Questions We Get Asked Often
Do you cover my town in Northwest CT?
Yes. CleanScapes works across Northwest Connecticut, including Litchfield, Torrington, New Milford, Kent, Sharon, Cornwall, and nearby areas. Our mobile trucks carry commercial surface-washing tools directly to your home. Call or message us to check scheduling in your town and set up an upfront project evaluation.
How often does a patio really need to be cleaned?
Most patios in our region benefit from deep cleaning every one to two years. Hardscapes sitting under shade trees accumulate moss and algae much faster than those in full sun. Routine cleaning prevents biological growth from taking root deep inside stone pores, protecting your joint sand and keeping the area clean for summer use.
How do you clear stubborn moss and algae without killing my grass?
We apply specialized pre-treatments designed to break down moss and algae at the root level without harming lawns or surrounding plants. We soak down neighboring garden beds with fresh water before and after application to protect your landscape.
Will high pressure wash out my joint sand or crack the stone?
If done incorrectly with a narrow spray nozzle, high pressure will blast out joint sand and etch natural stone. We use professional rotary surface cleaners that distribute water pressure evenly across the stone. Combined with mild pre-treatments, this lifts dirt smoothly without washing away sand or cracking masonry.
Can you clean driveways and stone walls at the same time?
Yes. We routinely combine patio washing with driveway cleaning, stone wall restoration, and deck maintenance during a single visit. Washing horizontal stone and vertical walls at the same time gives your entire backyard a clean, uniform look.
Do you clean wood or composite decks too?
We clean both natural timber decks and composite materials like Trex. We adjust our spray pressure and use mild cleaners to remove green mildew, pollen, and leaf marks without scratching plastic finishes or gouging soft wood grain.
How long will the job take?
An average home patio takes two to four hours from setup to final rinse. Larger properties with multi-level stone walls, long driveways, or joint re-sanding requirements may take a full working day. We always give you a clear timeline before starting work.
What credentials do your technicians hold?
CleanScapes brings 25 years of local experience along with certifications from the Interlocking Concrete Pavement Institute (ICPI) and the National Concrete Masonry Association (NCMA). As a local, family-owned business in Northwest Connecticut, we make sure every job is handled with safe, certified practices.
