"I contacted Mr Costello he came out on schedule, gave me a fair price, I agreed to have the work done. Mr Costello and his crew pressure cleaned, repaired, and stained my front and back decks. They look like brand new. Exactly what I was looking for. Thanks, Mr Costello for all the excellent work."

"Andy did an excellent job of cleaning 20 years of bottom paint off the bottom of my 21 foot fiberglass boat. Paint was removed to the boot stripe and there was no damage to the glass. The work was completed in my yard which was left clean with no residue. Great job"

"Justin was very professional, competent and thorough. He took pictures of the the issues with my skylight so that I could fully understand the problem and set up a time the very next day to repair it. He was very fair in his pricing and his communication was excellent. He knows what he is doing and does it in a very timely manner. I would also give him high marks for his accountability and promptness. I will definitely hire him again."

Deck Cleaning FAQs, answered by experts

It’s important to make sure the wood on a new deck is properly seasoned. Seasoning a deck is simple: Once you build it (or have a pro do so), just leave it alone so it can acclimate to the environment. If you don’t give the deck proper seasoning time before staining, the stain can lock in any lingering moisture and cause mold, rot, and other moisture issues down the road. Give the wood at least four to eight weeks to season before you stain.

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.

Deck stairs should have at least three stringers rather than two. The recommended minimum width for stairs is 36 inches, and the International Association of Certified Home Inspectors recommends at least three cut stringers to provide sufficient support on wood decking stairs of this width. Generally, stringers should be a maximum of 16 inches apart for wood decking and 12 inches apart for more flexible composite decking.

PVC decking tends to be cooler than composite because the material is less dense and absorbs less heat. However, it depends on the deck’s color. A dark-colored PVC deck may run hotter than a light-colored composite deck. If you’re concerned about your deck getting too hot, it’s best to stick to a light color such as beige or gray.

A deck doesn’t have to be perfectly level. Many pros even recommend a gentle slope to ensure proper drainage and increase longevity. The ideal gentle slope is about 1/8 to 1/4 inch per foot away from the property, leading water away from the home to prevent pooling and reduce the risk of damage. It also minimizes rot, mold, and other moisture-related problems.
