Deck Cleaning

At Keenwick, we take care of cleaning  decks that take the full force of Maryland weather, we restore the look and grip of your deck with a cleaning method matched to your specific wood or composite surface and remove any boards gray, slick, and dull.

Protect Your Property with a Professional Deck Cleaning

Decks are not siding or concrete, and they should not be cleaned the same way. Too much pressure can gouge soft wood, splinter boards, and strip finish. 

At Keenwick, we start by identifying your deck material, then choose the safest effective approach, from low-pressure soft washing to careful detailing by hand.

The result is a deck that looks refreshed and feels clean underfoot, without the damage that comes from aggressive blasting. Our deck cleaning contractors are background-checked and trained, so you get consistent, careful work on every visit.

The Real Value of Professional Exterior Light Cleaning

Exterior light cleaning is essential for maintaining the safety, security, and beauty of your home. With Maryland’s high pollen count, frequent storms, and coastal humidity, light fixtures quickly fill with cobwebs, insect debris, and grime, often reducing visible brightness by half or more before homeowners even notice.

Dim, dirty lights aren’t just an aesthetic issue. Reduced lighting around walkways, entries, and driveways can become a safety hazard for guests and a security concern after dark. Regular cleaning keeps your fixtures bright, your property safe, and your home welcoming.

Our Deck Cleaning Process

We keep the process simple and low-stress. We start by walking the deck to identify the material and any problem areas, protect nearby plants and furniture, then clean using the method best suited to your boards. We finish by rinsing thoroughly and checking edges, railings, and stairs so the whole structure looks consistent.

Deck cleaning also pairs well with a full exterior refresh. Many homeowners schedule it alongside house washing or a broader residential power washing visit to restore the whole property at once.

Frequently Asked Questions about Deck Cleaning Services in Maryland

How often should I have my deck cleaned?

Most decks benefit from a professional cleaning once a year, though shaded or tree-covered decks that collect more algae and mildew may need it more often. Regular cleaning helps keep the surface looking good and reduces slippery buildup.

It can, if the wrong pressure is used. Soft or weathered wood is easy to gouge or splinter under high pressure. That is why we identify your deck material first and use the lowest effective pressure, often a soft washing approach, to clean safely.

Yes. Composite and PVC decking still collect mildew, pollen, and grime in their textured surface. We clean them with a low-pressure method that lifts buildup without scratching or clouding the finish.

Yes. We clean dense exotic hardwoods with methods suited to their density and value, restoring their natural color and grain.
