"Angi is awesome! And they hooked me up with an awesome contractor named Bud Costello (Costello Coatings)! I had BAD decks, issues, and stuff. I contacted him via Angi and he was right over! He took great lengths to talk to us, ask us what we needed, explain all the processes, steps, etc., and what to expect. He answered ALL of our questions, and as a BOOMER, I really appreciated that! He was very polite, professional, and respectful! Then, he got the job done ahead of schedule, at cost, and it looks amazing! Wife is happy, that's all you need to know! I highly recommend him and his excellent HARDWORKING team. Here is before and after, but trust me, they were way worse looking and he fixed them, cleaned them, sanded them, then stained/painted them! Did I mention the wife is Happy?"

"I had a literal “garden” growing in my gutters. Nate explained everything he would do and the solution he uses. I also had a whole house cleaning. Including garage and deck. The results are amazing. He was prompt and efficient. Will use his services again and strongly recommend."

"Great! We were not sure that this technique was the right solution for our business so we needed to try cleaning a single mold first and test it before having the remaining molds cleaned. Andy was very accommodating in this process and made multiple trips to finish the job. He also worked with us to find the best media since surface finish was very important. We will absolutely us Aqua Terra Vapor Blasting again when needed."

Deck Maintenance FAQs, answered by experts

DIY staining or painting is manageable with proper preparation, including safety measures, necessary tools, and adherence to safe weather conditions for application.

No. In most cases, it’s not colder or freezing temperatures that affect decking materials but the amount of moisture that seeps into the materials as a result. For example, wood decking material is more likely to suffer from rot or decay when exposed to excess moisture from snow or ice. An extreme change in temperature can cause wood to expand or contract, but only if it’s not properly treated beforehand.

Most building codes require that railing spindles (also known as balusters) on decks or stairs be spaced no more than four inches apart. This safety standard is often called the '4-inch sphere rule,' which means a sphere with a 4-inch diameter should not be able to pass through the opening between balusters. This rule is in place to prevent small children and pets from slipping through the railing. For the same reason, the space between the bottom rail and the deck or floor surface should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is essential to check your local building codes to ensure compliance before starting your project.

Two coats of stain are ideal for the best protection and aesthetic appeal. However, if your decking is made of particularly dense hardwood, you may only need one coat. If you want an intense color, two coats are ideal.

The most likely causes of a deck leaning to one side are damaged deck posts, soil erosion, and inadequate deck footings. If you’re not sure about the exact cause, the best option is to call a contractor who can build a deck to inspect the damage and recommend the best way forward.
