"Painters arrived exactly on time and accomplished all tasks the same day. The manually stripped the deck and applied two coats of stain. They carefully cleaned and then painted the foundation concrete as it had got dirty over the years. They also scraped, caulked and painted a large bump-out window off our living room.

Deck Cleaning FAQs, answered by experts

The best way to sand a deck is by cleaning it, sanding the boards and stairs with 60- or 80-grit sandpaper, and sanding the railings and posts with 80-grit sandpaper. You should sand in the direction of the wood grain to avoid damaging the timber. When sanding your deck, use medium pressure and aim for an even sand. Pressing too hard with a sander can damage decks, as most are softwoods.

Wood decks need to be replaced every 10 to 15 years on average. Natural wood is highly vulnerable to infiltration and damage from moisture, which can occur rapidly due to exposure to outdoor elements. You can protect your deck and maximize its lifespan by sealing it every year or two.

Many composite decking manufacturers, including the popular Trex brand, offer warranties that protect against warping under specific conditions. These warranties typically last between 20 and 50 years, but they usually exclude claims related to improper installation of the product. Some manufacturer warranties only cover decks built by certified professionals.

Yes, and in some cases, frozen ground may improve the digging process for footings due to sturdier conditions. It’s easier than working in muddy conditions, which are more common in the spring. Contractors may use machinery that makes this step a breeze, so harder ground shouldn’t affect the building process.

Both a well-constructed deck and a patio can add value to your home. Patios are generally cheaper to build but don’t offer the same aesthetics as a quality deck. Therefore, decks can be more appealing to buyers than patios, increasing a home's resale value.
