"Working with N.E.E. Construction & Spray Foam on our project to build a ramp in our garage for easier access was a breeze! We posted a request on Angi’s for pros to build a ramp and Warren from N.E.E. Construction & Spray Foam was quick to respond. Within 1 week of our post we had exactly what we needed. Communication is very important to us throughout any project we do and Warren & his crew (Matt and Patrick) did not disappoint. They delivered what we wanted within the timeframe they promised and at the price they committed to when quoting the job. And the quality … fantastic! Take a look for yourself. Thank you Warren, Matt and Patrick from N.E.E. Construction & Spray Foam for restoring freedom and independence to our family."

"We hired this company. I don't mind paying but when they missed so many areas. It's very frustrating and I have to finish the job myself. Anthony promised a great job and so didn't Nicole. I sure didn't even get a good job. The hand railings are super rough, and where the pressure washer chewed up the wood it was never fixed. It was definitely a hack job. I was promised over the phone a walk through at the end. It never happened. Couldn't communicate with the workers. I couldn't understand them. Definitely the pictures that they posted on other jobs don't match what I paid for. A very disappointing experience with this company. I would shop around.. plus I included Anthony in the last few emails and he couldn't even respond back. Awful !!! The handrails was addressed in after the power washing. The owner needs to go back and see the truth. I have the email saved!!!! Give me your email and I would be gladly to send it you!! You shouldn't be sparky when your team hacked my deck. I will be re-doing myself. Such a joke of a company."

Decks and Porches questions, answered by experts

You can either nail or screw deck boards according to your preference. We recommend using 3-inch galvanized deck screws in this guide because screws offer superior holding powder over time. If you’re using screws, you can minimize the risk of cracking the boards by drilling small pilot holes before securing the boards to the deck joists.

Often, cracked deck boards are just an aesthetic problem and do not need replacement. However, longer or deeper cracks may be a problem, especially if they are on the end of the board. You can fill minor cracks with caulk, epoxy, or sealant to prevent further damage and improve their appearance. Replace boards with more serious cracks, which could become a safety hazard.

To child- or pet-proof your deck railing, look for railing systems with narrow spacing—under 4 inches—between balusters or panels. For added safety, consider installing a clear acrylic or mesh guard along the inside of the railing to prevent small limbs or paws from slipping through. Avoid horizontal rails that adventurous kids can climb like ladders. You can also add self-closing gates at stair openings to limit access.

Will pressure-treated wood rot? This wood could eventually suffer from rot, although it takes longer compared to untreated wood. Even though the chemicals applied to pressure-treated wood protect it, they eventually dissipate and leave the wood vulnerable. You can delay the appearance of rot in the treated wood by reducing its direct exposure to moisture and by painting it. Using fewer screws or nails in the wood—and thereby creating fewer holes in it—also delays the chances of rot forming.

Typically, most residential wooden decks are designed to support approximately 40 pounds per square foot, including the deck’s weight and any items placed on it. While this is fine for typical use, it is usually not enough to hold the weight of a hot tub filled with water and people. To safely support a hot tub, your wood deck will likely require reinforcement. Therefore, it’s best to have a contractor or a structural engineer assess it before hot tub installation.
