Old Sag Harbor houses are covered in painted clapboard or cedar shingles that have stood for many years. Salt air, mildew and pollen build up on them, and decks and fences turn gray and green.

These surfaces need respect. High pressure can strip old paint, split shingles and drive water into old walls, so we use a gentle approach.

✓Siding and whole-house washing
✓Decks and fences cleaned gently
✓Roofs soft-washed, never blasted

Clapboard, shingle and stone in Sag Harbor

Walk down any side street off Main Street and you pass houses wrapped in painted clapboard and weathered cedar shingle, many of them well over a century old. Salt air, shade from old trees and long damp springs give mildew an easy home on them.

Old exteriors need a light touch. Strong pressure can lift old paint, open seams in clapboard, split shingles and force water behind the walls. Our default on any older house is a soft-wash: a gentle cleaning solution, time to work, and a low-pressure rinse.

Paint condition is checked first. If paint is already loose or flaking, we will not blast it, and we tell you what we see before deciding the plan with you.

Brick walks, stone steps and patios can take a bit more pressure, but we still keep it moderate, since old brick and mortar can wear away.

Decks and fences are washed at a low setting after a small test patch. Roofs only ever get a soft-wash.

Storefronts and shop entrances on Main Street are part of our work too. We like early starts there, before the sidewalks fill.

Before any water flows, we cover garden beds and steer runoff away from neighbors - lots in the village are small and close together.

April and May, before the summer crowds and the summer guests, are the most popular months to book.

Picket fences, garden gates and window boxes are a big part of the village look. We clean them at the lowest setting, so paint and wood stay intact.

Patios and outdoor showers behind the house pick up mildew in the shade of old trees. Those are quick to freshen while we are there.

Sag Harbor exterior washing questions

Can you clean a house with old painted clapboard?
▾
Yes. We soft-wash older clapboard with a gentle solution and a low-pressure rinse.
What if some of my paint is peeling?
▾
We will not blast loose or flaking paint. We show you what we find before deciding the plan with you.
Are cedar shingles safe to wash?
▾
Yes, with a soft-wash. High pressure can split shingles, so we do not use it on them.

▾
No. We cover plants and steer runoff away from neighboring yards.
Can you wash a Main Street storefront?
▾
Yes. We usually start early, before the sidewalks get busy.

Beach houses and pool decks in Sagaponack get the same careful approach. Inside the house, our carpet cleaning crew can follow in the same week.
