Our crew cleans, brightens and preps your deck the right way, whether it's wood or composite.
About Deck Cleaning
Even in a dry climate, decks get dirty. Spring pollen, dust blowing off the foothills, leaves from mature trees and the grime left behind after snowmelt all settle into the grain. Shaded corners can grow mildew, and dark spots appear where pots and furniture sit. A good cleaning does more than improve the look. It removes material that holds moisture against the boards and gets the surface ready for stain or sealer. At SLC Deck Builders, our crew handles cleaning carefully and knows what your material needs.
Doing it carefully matters because cleaning can cause real damage. A pressure washer set too high or held too close will gouge soft woods like cedar and redwood, raising fibers and leaving marks that never fully disappear. Harsh bleach can strip color and corrode fasteners. Our crew relies on lower pressure, wood-safe cleaners and brighteners that restore the wood's natural balance after cleaning. Composite decks need their own approach, using products the board manufacturer recommends. We're happy to explain which methods and products we plan to use on your deck.
Cleaning is also a good moment for a close look at the deck's condition. With the grime gone, it's easier to see cracked boards, popped nails, rust stains around fasteners and soft spots. Our crew will point these out and suggest whether they need attention before the next winter. If you plan to stain afterward, the cleaning becomes the first step of the prep work. The wood needs to dry thoroughly before any finish goes on, which in Salt Lake City's low humidity is often quicker than in wetter parts of the country.
Many homeowners schedule a cleaning in spring, once the snow is gone, to get the deck ready for summer. Others prefer early fall, so the surface goes into winter clean and ready for a protective coat. Either way, you'll want to clear furniture, grills and planters beforehand and trim back any shrubs that touch the boards. Reach out with a few details and photos, and we'll give you a free, no-obligation estimate for cleaning alone or cleaning paired with staining.

Common Questions
Frequently Asked Questions
How often should a deck be cleaned?
Most decks in Salt Lake City benefit from a thorough cleaning once a year, typically in spring after the snow melts. In between, sweeping off leaves and debris and rinsing away pollen goes a long way. Decks under trees or in shady spots may need extra attention for mildew. If you stain your deck, plan on a deeper cleaning before each new coat. We can suggest a routine based on your setup and material.
Is pressure washing bad for my deck?
Not if it's done carefully. The problem is too much pressure, the wrong nozzle or holding the wand too close, which can gouge wood and leave permanent marks. We typically use lower pressure combined with appropriate cleaners and let the products do most of the work. Some decks are better served by a soft wash and a stiff brush. Ask us how we plan to clean your specific deck before work begins.
Can you clean a composite deck?
Yes. Composite boards resist rot, but dirt, pollen, grease from grills and mildew in shaded areas can still build up. The cleaning approach is gentler than for wood, and it's important to use products the board manufacturer approves. Some marks, like rust stains from metal furniture or grill drips, need specific treatment. Our crew is familiar with the major composite brands and knows which methods are safe for your boards and which to avoid.
How long does the deck need to dry after cleaning?
If you're just cleaning, the deck is usually ready to use once it's dry to the touch. If you plan to stain afterward, the wood needs to dry much more thoroughly so the finish can soak in. Salt Lake City's dry air helps, but drying time still depends on shade, temperature and the type of wood. We check the boards before applying any finish rather than relying on a set schedule.
