Client Testimonials
We care what our customers think of us and so should you.

I’ve used other power washing companies in Westchester and Westchester Wash and Seal is far and away not only my favorite power washing company to work with – but also the most talented and professional! Last summer they restored my deck which was covered in mildew, making it look better than it ever has, and they did it all with the best price I found! This year they power washed my Westchester home and walkways! Thanks for the great job Jim!

I tried Westchester Wash and Seal this spring for my pre-summer clean up. They did power washing on my house. I have to say, the work they did was fast and high-quality. I’ve been recommending them to everyone I know.

I’ve been a loyal customer for years. They do so much more than power washing and sealing decks – they also deliver some of the finest customer service found anywhere. I’ve had them strip wallpaper inside my home and paint my garden fence, all the work they do always looks incredible!

Westchester Wash and Seal is the most reliable power washing service I’ve ever used, and I feel like I’ve used them all over the years – we have always gotten our home power-washed  after the winter! My pavers and siding look BRAND NEW!
