"Maria and her team were very professional and courteous. They worked well together and hardly ever took breaks. This team hand brushed the entire house and it looks great. Clean-up was well done too. Maria was one of the only painters in the area that was willing to work us into her very busy schedule. She knew we had a very strict timeline and the job had to be finished quickly (we had renters arriving). Despite all the rain we had last week and an unfortunate personal issue, they got the job done just in time. I'm grateful for Maria and her team and their diligence. We would recommend this team and would definitely hire them again. Thanks Maria!

"I used Dean for two jobs and was impressed with how polite and knowledgeable he was. If he was not able to arrive at the specified time he informed me. The first job was a reshingle job for my daughter which was completed in a timely fashion without a hitch. The second job was a teardown and shingle for my home. There were a couple of glitches due to incompetence on the part of a worker who is no longer with him. Dean immediately went above and beyond what was necessary to correct these errors and I am confident that should any other problems arise he will take care of them. I will certainly contact him if I have any further work to be done"

Deck Cleaning FAQs, answered by experts

Expect to spend around $10,000 to $11,000 to replace a 20-by-20-foot deck. Using high-end materials like composite or exotic hardwoods can drive up the cost, as can custom features and design elements. You can also expect to pay more than average if your deck replacement requires a site evaluation or if you need the work done during the busy season.

Pressure-treated lumber is one of the most affordable types of decking upfront. This material is widely available, so you can usually find pressure-treated lumber at almost any local home improvement store you visit. Keep in mind that wood requires a lot of upkeep with repainting and restaining, so any kind of wood may be more expensive in the long run than something like PVC decking.

A covered deck can be a good investment that increases your home value—especially if you live in a hot region with a lot of sun. A covering over the deck means you can get more use out of it, even on the hottest summer days. With a permanent deck covering, you can even add ceiling fans to help cool down your deck for added comfort.

Whether you need a permit depends on the deck design and local regulations. Most areas mandate a building permit if the deck is over a specific height or if it's attached to a pre-existing structure. Shorter, freestanding decks may not require a permit, but you should check with local zoning ordinances and your homeowners association for specifics.

Liquid rubber is great for waterproofing, but it can damage your deck if it’s not applied correctly. First, it can trap moisture in the wood if the deck isn’t completely dry before application.  Second, applying it too thickly can create a heavy, rubbery surface layer that peels and cracks under fluctuating temperatures. For the best results, ensure the wood is completely dry before application, and apply the liquid rubber in thin, even coats. A quick inspection every now and then will help you catch any issues early, keeping your deck protected and looking its best.
