"Austin and Tyler were the best!! Very courteous, knowledgeable and very good at what they do. They took our complicated job and made it fantastic! They wrapped posts, built out our sunroom and fix our deck stairs. The site was cleaned up and spotless. We are definitely hiring them for all our projects and highly recommend them for your project!"

"Ryan owner of Granite State Concrete, He had come and gave an estimate on time which seemed very fair. I wanted a 3ft long by 16 ft. wide cement Apron for in front of my garage. As it turned out his uncle actually did the work. I thought his uncle did a nice job he worked late till dark to finish. he was supposed to come back and smooth out the apron, but he never did. He found out that Ryans estimate was 4 cement bags short. He had a worker go get them at Home Depot. He then finished the apron. They were supposed to come back, and power wash my driveway because some cement had got on it. I called Ryan many times he said he himself would come and power wash which never happened. Ryan did come late that night to receive my check. My fault is I should have held back part of the money, my own fault I knew better. Unfortunately, my picture wouldn't upload."

Patios questions, answered by experts

Yes, but ensuring the deck has a solid foundation with adequate footings is critical before building, as the weight of a sunroom will put significant pressure on the structure below. Even if your deck is properly constructed, it may not be able to handle the extra weight. While some basic, lightweight, prefabricated sunrooms can sit on a deck with a strong existing foundation without additional supports, in many cases, the foundation and joists will need reinforcement. It is always best to have a structural engineer perform an inspection to evaluate the deck's quality and structural integrity. A professional can help you decide if reinforcement is sufficient or if it's better to tear down the deck and start over.

In almost all cases, you will need permits if you plan on building a sunroom over your patio, but regulations and requirements will depend on your municipality. Permits to enclose your patio will usually cost between $300 and $1,000. Since navigating local building codes and zoning requirements is challenging—and the consequences of not following them can be extremely expensive—we strongly recommend hiring a sunroom builder to complete the work and pull the permits for you.

A deck is typically attached to a house and accessed via the back door. Decks are usually constructed from wood or composite materials. A terrace, on the other hand, is a raised platform that can be attached to or detached from the house and is typically made from a hard-paved material, such as paving stones. Terraces can be built on the ground or on the roof of a home.

Building a sunroom can take anywhere from two weeks to six months. An average-sized sunroom typically takes between two and eight weeks to complete, but more elaborate or larger projects can take longer. The final timeline depends on factors such as the sunroom's size, features, structural requirements, type, and whether it's a retrofit or a new build from scratch.

A professional can design and construct sunrooms or patio enclosures that meet structural standards, optimize environmental conditions, and integrate seamlessly with existing architecture. This ensures the project enhances home value and provides long-term enjoyment.
