"We were looking into redoing our old deck and got a quote which we thought was reasonable for our large deck. Then for another estimate, we called 7th State Builders. They explained that for the same cost, we could get a paver stone patio (which in the long run is far less maintenance). The owner worked with our budget and the gentlemen who laid our pavers were extremely professional and worked within our wishes. They removed the deck and finished the patio in about a week. Awesome job! After a week or so, it had rain for a period of time and we noticed that a small dip in the patio was collecting a puddle. After a call, they came out and fixed the problem. We would definitely recommend this company for a patio."

Deck Maintenance FAQs, answered by experts

A sunroom will add more value to your home than a deck, but with a much higher up-front cost. Depending on its construction and function, a sunroom may be counted as additional living space, while a deck is strictly an outdoor feature. Both will increase your home’s value, but the sunroom will have a much bigger effect.

Any wood deck provides some ventilation to the area below, as is the nature of that type of deck design. However, areas that experience excessive humidity and associated moisture benefit greatly from a dedicated ventilation system in the form of strip vents. This addition helps the various wood boards contract and expand evenly throughout the years and reduces the chances of twisting, warping, and buckling.

Yes, using sustainable materials and recycled composites offer green solutions.

Yes, adding railing to a deck is a great way to improve safety and your home’s aesthetic appeal. Railings can be constructed from wood, metal, or composite, and there are plenty of choices regarding design and style. Always consult local building codes before starting any building project—there are often requirements regarding spacing and height that can differ slightly from place to 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.
