"I very highly recommend Jamie Adams. He showed up on time, finished on schedule, and did an amazing job, absolutely top-notch work. He has attention to detail, finds great solutions to weird quirks that come with a property's existing layout. I trust his judgement, and take his recommendations/solutions. Which is saying a lot I am normally quite suspicious of contractors, but Jamie has won my trust and loyalty. If any of my buildings need work, Jamie will get it. The quality is great and the cost is reasonable, with no sticker shock."

"Andrew and his crew did an amazing job building this garage. Even though he ran into some issues with the supplier of products he went above and beyond to make sure we were kept informed. Additionally, he also replaced (and improved) an existing garage door in the lower level of our home. He also repaired some siding on our house. They even put our two garage door openers in. Overall, we were more than please with his work and his crew."

"Custom 32’x36’ Goldiva Goldens LLC showroom plus 14x32 pergola and 14x67 pergola plus a small bathroom in the basement; re-tile basement area too. Scott Turcott, Tyler & Michael are great to work with, great communications. In 20 months of building my showroom there wasn’t a single disagreement. If something “didn’t work” as envisioned, like an incinerator toilet that burned the ash, Scott gave me the options. They’re a fabulous team!!"

"What I found outstanding was the excellent communication from Greg about my project at all stages, from the first meeting, through the repair process, to the completion. I always knew what to expect from the day-to-day work and I felt he and I were on the same page. My facia board, gable board, removal of moss on my roof and door replacement was accomplished safely and thoughtfully by his competent crew. I would recommend this company to anyone as I feel they are very trustworthy, and I hope to use them again for my next project"

Basement Remodel FAQs, answered by experts

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

To determine if your basement walls are suitable for finishing, assess their structural integrity and moisture conditions. Look for any signs of damage, such as cracks, bowing, or excessive moisture. Ensure proper drainage and address any underlying issues before proceeding. 

Consult with a professional if you're uncertain about the structural stability or potential risks associated with finishing your basement walls.

Yes, you can add a door to your basement—it might even be required, depending on building codes in your area and whether or not you’re using the basement as a bedroom. A basement contractor can give you some advice on installation and help you add a door to your basement.

While framing a basement is not as difficult as finishing a basement, it's something you should typically leave to the pros. That’s because if something is installed correctly, it will affect your entire basement. However, you can take care of some of the smaller tasks, like filling holes or putting up some insulation.

A finished basement does not always count as square footage, as this varies by state regulations. In areas that allow below-grade spaces to be included in a home's official square footage, the basement must typically meet certain conditions. These conditions often include having a functional egress and being a livable space with flooring, finished walls, and temperature control. To be certain, contact your local assessor to confirm your area's specific policies regarding basement square footage.
