"I would absolutely recommend Building Exteriors They were thorough throughout the whole process of our renovation — from our initial call to completion to project. Luis and staff were consummate professionals. They took the time to hear our concerns and expectations and address them with clarity and honesty throughout the reno process. We never felt pressured into any “upselling” that usually happens with other competitors. It felt that our best interests were always the priority and the experience was so refreshing! All Building Exteriors employees seem to take great pride in their work … as if they were working on their own home. The craftsmanship and attention-to-detail was the best I have ever experienced . They made our home exactly the way we had envisioned it and couldn’t ask for anything more!"

"The words that come first to mind are "conscientious" and "honest." Overall, "professional" describes their attitude. I appreciated being thoroughly advised as to their procedures, and was treated with respect whenever I had a question or concern. When I wanted a change in the original plans, they did as I requested, and with understanding and respect. The work was well done and in a timely manner. And the clean-up was thorough. Now, with my new deck, I no longer worry about my giant dog falling through the rotten wood of the old deck."

"Eric is great! I contacted me through text, it was easier to figure out scheduling. He show up and completed the task. He even discounted us for a scary lil fire that occurred with the wiring. He's a perfect gentleman and very hard worker. My mother will want to hire him to help with our back deck."

Deck Maintenance questions, answered by experts

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. 

For a 12x20-foot (240-square-foot) deck, you can expect to pay between $7,200 and $14,400. This cost is based on a general price of $30 to $60 per square foot. The final price will depend on factors such as the decking material, design complexity, deck type, location, and local labor costs. Keep in mind that add-ons will increase the total; for example, adding an under-deck drainage system to a deck of this size could cost an additional $7,700.

A quality, well-maintained PVC decking can last 30 to 50 years. It’s known for being one of the most durable types of decking materials, with composite decking having a 25- to 30-year average lifespan and some softwood deckings only lasting 10 to 15 years. Luxury hardwood decks like Ipe may last longer than PVC decking, but they can cost more and require more maintenance.

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.

The average cost to professionally clean or pressure wash a deck is around $150, with prices typically ranging from $100 to $600. Several factors influence the final price, including the deck's size, material, condition, and how long it has been since its last cleaning. For a smaller deck of about 300 square feet, you might pay around $100. For a larger deck of 1,000 square feet or more, the cost could be closer to $300 to $400. Decks that are very dirty or haven't been cleaned in years may require more time and special detergents, which will increase the price. The deck's material also plays a role. Wood decks often cost more to clean because they require a gentle power washing technique to avoid damage. Composite decks are typically less expensive to clean, and cleaning a metal deck may cost around $100.
