"I cannot say enough about this project and Abe! We had a ?sweaty? basement refinished. Abe walked us through every thorough and comprehensive step that he took to ensure the new living space would be safe and functional for many years to come. His estimate was accurate, his pricing, fair, and the subcontractors that he hired for plumbing and electric were professional, friendly, and swift. We asked Abe for a number of specialty finish carpentry projects and all were finished meticulously. We are still finding little surprises here and there that show just how much he cares about the function and beauty of his work! We had a custom glass shower door built, a hydraulic Murphy bed, and a ?secret bookcase door? leading to my husband?s office. Every single thing came out just beautifully, and all of our friends and neighbors are terribly impressed! We will absolutely be working with Abe again?He?s a master of his craft!"

We have a long, uphill driveway, a curved walkway, and a back deck.  Shawn Craig has been our "plow guy" this winter and we couldn't be happier with Craig Construction's service.  Our drive is neatly plow, the walkway cleared, and even a path to propane tank is kept accessible!  And yesterday, I asked late in the afternoon if they could shovel our back deck and they did it while clearing the driveway after Blizzard Juno!! I am very glad to be working this winter with Craig Construction.

"We consider ourselves very lucky to have found just the right person in Wade Ambrose, to handle this complex job. Replacing 200+ linear feet of rotting exterior "rain boards" with plastic lumber. We knew that it might seem straightforward, and a certain amount was just that, but rot had set in below the top layer, and Wade and apprentice Sage, expertly removed all that, replaced it not only in the best workmanlike manner, but a real touch of aesthetics when faced with unforeseen issues: garden hose bibs, propane tank ice shields and piping, movable stairs that needed to be close to house but still shed rain. Because of all that, it took a full two weeks, but much was due to weather--beyond anyone's controlled-- and supply issues. Clean work site during and after and took all the demo away. Good for next 30 years. We also wanted to praise Wade for his good balance of family/work life. Even though there were long days of sunlight in August, Wade was sure to not go for 12 hour workdays, and safety issues that can result. He was happy, we were happy, Sage was happy to learn with him. You will be too. (And below estimated cost!)"

"I can't overstate the quality of the work these folks did. We had our unfinished attic converted to living space, and the space had a lot of funky angles and old framing. G.A. Doughty's team did an incredible job making it work, including a half-bath! We're very pleased with the result. Everyone at G.A., the project manager, office staff, and all the subcontractors were very polite and fun to work with. Everyone who came to the house was very friendly. The only issue we had was that for a few months during the middle of the project, things seemed to stall out for about 6-8 weeks. I think they were having some availability issues with subcontractors and were overloaded from other projects."

"They did a good job especially considering how brittle my old siding had become over the years. I’m pleased with their work and the price was right. I plan to hire them to do a couple more small jobs that I’m to old to do myself."

Basement Remodel FAQs, answered by experts

You should always use high-quality lumber for your framing in order to ensure it will last the test of time and resist moisture. Use 2-foot by 4-foot lumber that is pressure-treated for your framing.

Lifting a house and adding a basement is one way to add usable square footage. Lifting or jacking a house is a complex process, and it can be expensive, not to mention that you won’t be able to live in your house while it’s lifted, due to safety concerns. Lifting a house should only be done by experienced professionals.

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:

  • Replacing insulation 

  • Replacing carpet or other flooring 

  • Adding heating and cooling

  • Adjusting or adding walls and doors

  • Altering or adding plumbing elements

If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.

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.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.
