"Sheldon and his team were everything you could want in a painter. Prompt communication, fair price, good advice and excellent work. They went above an beyond to fix the little things that they found. No extra cost. They even moved the wood pile away from the deck and restacked it. High marks across the board."

"In a previous review I stated I had not heard anything from the company about necessary repairs. That WAS NOT an issue with the company or its owner! It was an issue with electronic communications failure on my equipment. That issue is resolved (I hope!) I would highly recommend this company to anyone needing any type of repair for their home."

"We had our back deck demolished and replaced and our side decks refinished. We love the results of both jobs. Brian and his crew worked hard and were very professional. They hauled the demolished back deck away, moved our deck furniture and raised planters off the side deck and replaced it when finished. They also extended a downspout so it would drain away from the house and built a step from the bedroom door to the back deck and moved firewood away from the deck so I didn't have to. These were all thoughtful and not inculded in the bid. All the crew was cheerful and nice to be around during the time they were here."

Deck Repair FAQs, answered by experts

Be careful when choosing a product to help you remove ice from your wood deck. Never use sand, gravel, or salt, since these items can damage and scratch the wood. Instead, look for chemical de-icers that are marked as safe for wood decks or use hot water to melt snow and ice.

Most building codes require that railing spindles (also known as balusters) on decks or stairs be spaced no more than four inches apart. This safety standard is often called the '4-inch sphere rule,' which means a sphere with a 4-inch diameter should not be able to pass through the opening between balusters. This rule is in place to prevent small children and pets from slipping through the railing. For the same reason, the space between the bottom rail and the deck or floor surface should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is essential to check your local building codes to ensure compliance before starting your project.

Yes, using sustainable materials and recycled composites offer green solutions.

No, you don’t need a permit to repair and replace a few boards on an existing deck. However, if you’re making structural changes to the deck or tearing down the old one and building a new one, you will likely need a permit. Check with your local municipality for the regulations and rules in your area, or ask a local contractor who builds decks for advice.

Yes, it’s definitely possible to build a pergola on an existing deck. All you need to do is attach the pergola support beams to the deck’s joists and build up from there. Beware that mistakes can damage your deck, so if you’re at all unsure of the process, play it safe and hire a pro for your custom build.
