"They started each day at 8:00 AM and worked until 5:00 or later. They were very polite and professional. The lead person George would explain what they would be doing each day and then perform the tasks. The deck looks like it is brand new and the redwood has the original color and grain. Note: the bill included 4 hours of setting the deck screws so they could sand. Otherwise they performed to the bid."

"Rocky and his team were professional, fast, and cost-effective! We had a three-car garage that we wanted to get professionally epoxy coated as I run a small business detailing cars out of it. Rocky came by the same day to provide me with a quote and was able to get the work done the next weekend! The pricing was competitive, the quality was top-notch, and now my garage looks like a professional auto body shop!!! He was also super knowledgeable and the materials and the prep and gave me suggestions on what type of material would work best in my application. Since he has experience in the commercial space, none of the material was that home Depot garbage that delaminates in a year or two. Everything was commercial grade and has a great warranty. I highly recommend him for any type of epoxy floors!"

"All I can say about our experience using Cunningham Construction is - they were outstanding! They handled our whole job, from beginning to end, in the most professional manner, communicating with us every step of the way, always following through on their promises, and ultimately producing a most beautiful new gallery building for our artwork. We couldn't be happier! Certainly 5 stars in every aspect and the strongest recommendation we can give! Kudos to you two, Paul and Vicki! (from Karen & Matt Wyse, Moraga)"

"John is a super honest guy, who takes a lot of pride in his work, and isn't someone who is out to take advantage of people. I had 4 other bids besides his, and he provided not only the best price, but the best solution to remedy my deck issues. He went above and beyond what was stipulated in his bid to ensure that the problem that I had experienced would not reoccur again in the future. And, he didn't ask for any additional money. His work is top notch and I will be having him back to work on another project down the road. I highly recommend him!!!!"

Deck Repair FAQs, answered by experts

Space deck handrail posts four to six feet apart. If the posts are more than six feet apart, the railing will be less able to withstand lateral forces and is more susceptible to breaking. Additionally, railing posts that are more than six feet apart may not be up to code, and you may face fines and be required to reinstall the posts to bring them up to code.

You can use a few different tactics to prevent your deck gate from sagging. Aside from using strong, rot-resistant woods, introducing a diagonal element—such as a tension rod or solid piece of wood to act as a brace—across the gate will offer better support. You can also use rigid joists to prevent the gate from sagging.

Decks require several inspections during and after the building process, but the specifics vary depending on where you live. Most areas mandate that decks comply with local building codes and safety regulations for the foundation, framing, and structure. Some pros recommend a footing inspection, which verifies the depth, width, and location of the various footings to ensure they offer enough foundational support.

For the best results, stay off of your deck for at least 48 hours after sealing it. Giving the sealant at least two full days to cure ensures it can fully penetrate the wood, giving you the most protection from sun and weather damage later on. Walking on the deck too soon can prevent it from properly curing and cause your deck to weather prematurely.

That depends on the condition of your deck. An older deck that looks drab, worn, or has multiple damaged boards might be worth replacing before selling. However, if your deck is in good condition, you can simply clean, repaint, or stain it.
