What we wash

Every surface gets the pressure it can take. Soft washing for siding and roofs, surface cleaners for flat concrete, and a full rinse before we leave.

Before and after house wash on one of our jobs: the porch and a grimy stone wall on the left, the same house clean on the right

House washing

Soft washing for vinyl, clapboard and painted siding. A low-pressure rinse with cleaning solution lifts mildew, pollen and road film without forcing water behind the siding or stripping paint.

What a New England year leaves on your house

Every season leaves something behind. Here's what we wash off.

  1. Spring

    Pollen and mildew

    Yellow pollen settles on everything, and siding that stayed damp all winter starts growing green mildew on its shady side.

  2. Summer

    Algae and grime

    Heat and humidity spread black roof streaks and green film. It's also when patios and decks get the most use.

  3. Fall

    Leaves and tannins

    Wet leaves stain concrete and decks brown. Washing before the first freeze keeps grime from sitting under the snow.

  4. Winter

    Salt and sand

    Road salt and sand leave a white crust on driveways, steps and the bottom of your siding. We clear it once the thaw comes.

Roof prep for GACO silicone coatings

A silicone roof coating only bonds to a clean roof. Before every GACO silicone application, the commercial roof has to be pressure washed first.

For the past four years, Certified Roofing has contracted us for that prep work, cleaning commercial roofs ahead of their GACO silicone applications. Planning a coating job? We'll have the roof clean and ready for your crew.

contracted by Certified Roofing to pressure wash commercial roofs before GACO silicone goes down

Certified Roofing was named a GACO 2025 Top Contractor.

A UMass Memorial Health roof, start to finish

UMass Memorial Health hired Certified Roofing to coat this roof with GACO silicone, and Certified Roofing brought us in for the prep. Here it is as we found it, after we washed it, and after the silicone went on.

Two-story commercial building with walls of clean glass windows on a sunny day

Commercial window cleaning

Interior and exterior glass for commercial buildings. We've done a lot of window cleaning for UMass Memorial Health, inside and out.

Window cleaning is commercial only. We don't take residential window jobs.

Outside

We clean exterior glass with XERO pure-water technology. Filtered water goes up extension poles to a brush that scrubs the glass and frames, so we can reach higher windows from the ground. Nothing is left in the water to dry on the glass, so windows dry spot-free with no soap.

Inside

We clean interior windows and glass by hand, so the view is clear from both sides of the building.

How XERO pure water works

  1. Carbon filter

    Takes out chlorine and sediment from the tap water.

  2. Reverse osmosis

    Strips out most of the dissolved minerals.

  3. Deionization

    Removes what's left, down to almost pure water.

  4. Spot-free rinse

    Pure water lifts dirt off glass and frames, then dries clear.
