"We hired Bradley Construction LLC to complete our basement renovation. The renovation entailed adding a laundry room, full bathroom, framing the basement, and everything that goes along with that. We worked through the design with Terry Bradley, Kim Bradley, and a couple of their subcontractors to get everything just right. This design and quoting process was smooth and ensured everyone was aligned. Once the project kicked off we worked with Kim Bradley as Project Manager. Kim is extremely thorough, dedicated, and was our biggest ally through the project. Kim ensured that all the subcontractors showed up as needed to keep the project on schedule and that everyone completed their work per the plan and at a high level. During the project a couple mistakes were made and without fail Kim picked up the phone and immediately made things right. Kim, Terry, Brian, Glen, and all the folks at Bradley have been a pleasure to work with. It's refreshing to find a true trustworthy professional."

"Trevor and his team did a brilliant job with the renovations of the house that was not in good shape prior. He was communicative and available to chat at all times to provide updates. The attention to detail on all tasks is what impressed the most. He was flexing with his pricing and got the job done before estimated completion date. I would definitely use his services again."

"The Moore brothers were great. They satisfied my Home Owners' Association with a detailed proposal within an hour of inspecting the job. They itemized and described the work, which included cleaning off the mold, replacing insulation, repairing joists, encapsulating the crawlspace, and creating a French Drain on the exterior of my unit to redirect the rain. They also set up my dehumidifier in the space with a wireless meter I can read from inside . Their price was in line and they did everything they promised in good order, good humor, and respect. Three other companies bid and were not even close... in promptness, plan, OR price. I highly recommend Jon and Danny Moore."

Basement Remodel FAQs, answered by experts

It’s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is $32,000 (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Yes, most general contractors require an initial down payment. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.

Envision the type of bar experience you'd like to create for your guests. For example:

  • Does your basement have enough finished space for bar stools or seating?

  • What type of additional lighting would set the tone for the room?

  • Are there basement windows or an HVAC system?

  • Do you need new plumbing in your basement for a proper wet bar?

  • Could you be happy with a built-in wall cabinet bar rather than a full-scale wet bar?

Building up by adding square footage to the top of your home is often less expensive than adding a basement, but it depends on the specifics of your house, your property, and supply costs. Because building a basement requires excavation, it can be a more expensive option than building up.
