"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."

"We got a few estimates for a new custom deck and chose Bayside Builders Group because of their detailed breakdown. Our project manager, Dan, made sure everything stayed right on budget with zero hidden fees. He checked up on the progress constantly and kept the crew moving efficiently. The deck looks stunning and the structure is incredibly sturdy. Huge thanks to Dan for a job well done!"

"The Bayside Builders are the best at what they do! I've had my deck for years but it was looking worn and outdated. They helped me transform this area into something new - a more open, brighter space with plenty of room to relax on hot days or enjoy dinner under starry skies. What better way to enjoy our new outdoor space right?"

"Josè did an excellent job installing our patio screens. He was very communicative about the process and asked for my approval before making any necessary changes. I really appreciated Josè’s thoroughness from beginning to end of the project."

"We had them do a full house siding project and it turned out great. The crew worked hard every day, kept things clean, and always let us know what was going on. You can tell they care about doing it right, not just rushing through it. The house looks completely different now and we?ve already had neighbors compliment it. Glad we went with them."

"Leo did a very extensive plumbing repair that required digging through my bathroom floor and replacing a huge pipe to the outside. He also prepared and installed piping and fixtures for a bathroom remodel. Always showed up when he said he would and had a great crew. Cleaned up as well. Would highly recommend."

Deck Repair FAQs, answered by experts

Before installing a new railing, check the condition of the deck frame and joists, especially around the perimeter where posts attach. If boards are loose, soft, or show signs of rot, the structure may need repair. A deck pro can inspect your framing to confirm it meets load-bearing requirements.

Applying too much sealer to a deck might seem like extra protection, but it can cause more harm than good. Wood is a porous material with a limited capacity to absorb liquids. When you go overboard with sealer, the excess can't soak in and instead forms a film on the surface. This leftover layer is prone to peeling, cracking, and trapping moisture, ultimately defeating the purpose of sealing in the first place. 

The best paver for your pool deck depends on your budget, style, and how much maintenance you’re willing to invest. Granite is one of the best low-cost pavers for pool decks. It’s very slip-resistant and durable, too, making it a top pick. Travertine is a high-quality material that resists freeze-thaw cycles, looks stunning, and won’t get hot in the summer. The only downside to travertine is that it costs more than granite.

Yes, Ipe wood is a popular high-end choice for pool decking. It repels water and is naturally slip-resistant. It's not susceptible to mold, mildew, or rot, either, so it lasts longer and is cleaner and more hygienic than other popular decking materials. However, remember that due to its status, it is a very high-cost wood, and you might find that an alternative would serve you just as well for significantly less.

You can nail or screw composite decking, but 3-inch decking screws are the better fastener choice. Unlike nails, decking screws won’t back out of the composite material over time. There’s also little danger of splitting composite material when driving screws, so you don’t need to pre-drill holes unless otherwise recommended by your decking manufacturer.
