"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!"

"Very easy to work with. I'd used them before but this time I got estimates from other contractors and was amazed how much more reasonable Cal Preserving was. The difference may be that the others pointed to additional steps that could be taken. Did Cal Preserving "miss" these things or recognize they weren't necessary--I'm inclined to believe the latter."

"Fantastic job! I can't believe how bright and clean the deck and the surrounding areas look. It's clear that Blue Wave takes pride in their work and goes the extra step to please the customer. The windows have never looked better. Some are quite hard to reach and have not been cleaned in ages. They look brand new. I'm so happy with the expert and professional service provided by Indira and her team. I will definitely call Blue Wave again."

"DJ's recommended a color scheme and painted the exterior of our house. They weren't the lowest or highest quote, but they did an excellent job, went out of their way to please, great/friendly/nice crew and I would highly recommend them. They also spent a lot of time on the prep work on a 30 year old stucco house."

Deck Cleaning questions, answered by experts

When building a deck, #2 grade lumber is a go-to for several reasons. It’s strong, budget-friendly, and works well for most framing and decking needs. But upgrading to #1 or Appearance Grade can give your deck that extra visual edge if you're after a cleaner, more polished look for high-visibility spots.

Building codes for deck railings can vary by location, so it's important to consult your local regulations before construction. Generally, a guardrail is required for any deck that is more than 30 inches above the ground.

For residential properties, the standard minimum height for a deck railing is 36 inches. However, some states and municipalities have stricter requirements; for example, California and Washington mandate railings that are at least 42 inches high. Therefore, a 42-inch railing is not considered too high and may be required in your area or chosen voluntarily for additional safety.

In addition to height requirements, codes also specify other safety features, such as the maximum spacing between balusters to ensure they are close enough to prevent a child from squeezing through.

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.

Most building codes list a minimum width of 36 inches and a maximum height of 7¾ inches. However, for the most comfort and spaciousness, you’ll want to aim for a width of at least 48 inches and a height of 7 inches. Again, it’s always a good idea to base your numbers off steps that you already use comfortably.

In many areas, a floating deck that isn’t connected to your home and stays under 200 square feet and below 30 inches in height may not need a permit. These freestanding structures are often considered low-risk, which can simplify the building process. However, building codes vary greatly based on location. Before investing in any home improvement project, check with your local permitting office for deck-building guidelines.
