Why It Matters

Deck Cleaning That Matches Your Material

Your deck is an extension of your living space, but it sits exposed to sun, rain, and shade all year. Dirt, algae, and mildew build up, make the boards slippery, and wear down the finish, whether you have a natural wood deck or a composite like Trex or TimberTech.

Under Pressure House Washing cleans each deck according to its material. We soft wash composite, delicate, and tropical hardwood decks such as Ipe and Mahogany, and use controlled pressure on heavily stained wood. The result is a clean, safe deck that is ready to use or to prep for staining.

FAQs

Common questions about deck cleaning in New Jersey.

What is soft washing, and how is it different from pressure washing?

Soft washing uses low pressure combined with safe, specialized detergents to clean delicate surfaces like siding and roofs without causing damage. Pressure washing, by contrast, relies on higher-powered water and is ideal for tough surfaces like concrete and pavers. We choose the right method for each surface so your property is cleaned thoroughly and safely.

Are you licensed and insured?

Yes. Under Pressure House Washing is a registered New Jersey Home Improvement Contractor, registration #13VH13996500.

Can you clean my deck or patio without damaging it?

Yes. We adjust our method to the material, using appropriate pressure and detergents so wood decks, pavers, and patios are cleaned safely. This lifts away dirt, algae, and stains while protecting the surface underneath. Your outdoor spaces will look refreshed and inviting.
