"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

Professional remodelers streamline the process, manage permits, and handle renovations efficiently—significantly mitigating risk while maintaining standards.

Create a checklist, reimagine the space use, set a realistic budget, choose materials and aesthetic details, and get professional support for guidelines and troubleshooting.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.

You can paint your ceiling or install a drywall ceiling if the ceiling is unfinished, as they take up less headroom than drop ceilings. 

If there are pipes in the way of ceiling installation, you can do one of two things: reroute the pipes or adjust the installation to fit, which will cost extra.

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.
