"I had an outdoor playground set. Adrian was professional and hard-working. Great communication and he brought all the required tools and equipment. He showed up first thing in the morning on a short notice and it was all done before the end of the day. The assembly looks great and I know the kids will love it!"

"The greatest roofing company I,ve ever encountered is Northwest Builders and Renovation. Moshe, with whom I collaborated to effectively complete my roof replacement project. The process proceeded without a hitch from the first step to the last completion of the work. In addition to what the neighbors were saying about the works quality and professionalism, I wanted to add one more thing. Completely happy!"

"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)"

"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."

Deck Repair FAQs, answered by experts

When deciding if you should use 2x6 or 2x8 deck joists, consider the size of the deck, joist spacing, and materials. Larger decks, larger-spaced joists, and weaker wood all require more support, meaning they need larger joists. For example, 2x8 redwood joists spaced 16 inches apart can only safely span up to 10 feet and 7 inches. On the other hand, 2x10 southern pine joists spaced 12 inches apart can be as big as 16 feet and 2 inches. If you aren’t sure what size joist is best for your project, speak with your deck builder.

The best material for your deck depends on several factors, including your budget, location, aesthetic preferences, and the level of maintenance you’re willing to do. Wood decking, like redwood, ipe, cedar, and pine, lasts the longest, but it’s more expensive and requires more upkeep than composite and synthetic decking.

The best way to clean your decking is to clear debris from the gaps between the boards, sweep the surface, rinse it, apply cleaner, rinse again, and let it dry fully. A homemade deck cleaner made of two gallons of warm water and 1/2 cup vinegar is a simple cleaning solution for both wood and composite decking. You can sprinkle baking soda on any spots with mold or mildew, then scrub the area and rinse clean. 

If you want to make a deck cleaner from products already in your home, there are various options. The most common is to use a gentle blend of 1 gallon of warm water and 2 tablespoons of ammonia-free dish soap. You can also mix water with distilled vinegar. Sprinkling on some baking soda can help to remove mold and mildew. You can add oxygen bleach (but never damaging chlorine bleach) to the water and ammonia-free dish soap solution for something a bit stronger. 

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.
