"I had to have my deck refinished because I had done it myself and really did a bad job:))) Alex responded right away and was able to get in and get the deck stripped and refinished quickly. It really looks great, he did a wonderful job. He was reliable and in great communication about the cost, the likely outcome ( since he had to try to remove my very over applied oil based stain) and about the timing of the work. I would recommend him and I will use him again for any deck or painting needs I have!! excellent!"

"This review is long overdue. Cameron and his crew were fantastic! Due to woodpecker damage, I needed to have my house re-sided in Hardie Plank, and I also developed a bad case of, "well, as long as we're doing that...." They removed the old siding, fixed any areas underneath that needed re-sheathing or re-framing (due to water damage), and then installed the new siding. That was all included in the original price quote. I also decided to update most of the windows and sliding glass doors in the house. When the new custom bay windows arrived and were incorrectly configured (no one's fault on my end or Cameron's, as I recall), he graciously re-ordered them, made triple-sure the configuration was correct, and only charged the price difference between the prior configuration and the correct one. His crew also replaced some exterior stairs and 3 decks for me, one of which was badly deteriorated. Not even pressure treated wood can withstand years of Seattle rain, so my main deck was rotting away. They did a beautiful job of repairing and replacing, so I also had them do the walkway up to to my front door to match. Then came the painting, and the paint job on my house is drop-dead, stunningly gorgeous. It was so stunning that the next two neighbors up from me (with identical floor plans), decided to paint their houses as well. All three are now bright, cheery, primary colors. Along the way, Cameron and the Modernized Exteriors crew did lots of little extras, kept me informed about how the work was going, had me inspect frequently, and charged very fair prices. They even sent someone out to fix an old window leak that hadn't gotten fixed by the re-siding process. My fiancee kept an eye on the work progress too, and as a tradesman himself, he highly approved of the quality of their work. I can't say enough good things, and I will hire them again in a heartbeat for exterior work. I just wish they also did interior work, so I could hire them for a bathroom remodel!"

"Rite Professional Services is fantastic! I needed some big tree limbs cut from a hazelnut tree that were going over my roof. Jorge came to give me an estimate. He was on time very professional and explained what he needed to do. I felt very confident with his advice. Amazing service and my backyard is letting more light in. Will 100% hire Jorge again. So happy I found Rite professional Services. Please hire with confidence."

Deck Maintenance FAQs, answered by experts

Staining and sealing the underside of a deck creates a moisture barrier but traps water in the boards, quickly leading to rot. No matter how well you seal the above deck, water still gets through via nails and screw heads on the surface. Allow this water to flow naturally under the deck, where it is routed through the drainage system.

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.

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.

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.

Composite decking might cost more upfront, but it delivers value in terms of durability. Unlike wood, composite material resists common deck problems such as rotting, fading, warping, and all the other things you don’t want a deck to do. The extra processes lead to a higher price tag, but you’ll save big in maintenance costs down the road.
