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!"

"Adam and his team did an amazing job on completing a backyard fence for my family. He was hardworking and detailed with the work. Kept me updated through every step of the way from the permit process, ordering materials and check-ins as the build was happening. Our fence is great! He also completed a custom railing and gate to attach to our existing deck. Will definitely be using we do it all again for future projects."

"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

Prefab kits like a small sunroom for around $20,000 or even a basic gazebo roof for as little as $60 can save you big over professional installation. However, you lose the option for customization, and these structures tend not to last nearly as long. As for bigger projects like a deck or patio, you shouldn’t go with the DIY route unless you’re fully prepped with the tools and know-how to get it done right. Mistakes can be frustrating and costly, so choose a pro if you’re looking to eliminate your risk of error.

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.

In most parts of the U.S., adding a screened-in porch requires a building permit. Since this type of project often involves structural work and changes to your home’s footprint, homeowners should adhere to local guidelines. That said, permit rules can vary widely depending on where you live and how extensive the project is. Before you start sketching out plans or ordering materials, check in with your city or county’s building department to avoid headaches, fines, and potential structural issues down the line.

The life span of your solarium will depend on the materials used and how much wear and tear the room experiences from the inside and from the outside due to weather. On average, you can expect your solarium to last anywhere from 10 years to 50 or more. In rare cases, such as with old estates, solariums can last over 100 years.

The average cost to screen-in your patio ranges from $2,000 to $4,000. How much you spend depends on the size of your patio, the materials used, and construction complexity. Some patio screen room kits are easy to DIY, but you may need to hire a local screened-in porch builder and obtain permits for more complex designs.
