"We had a pretty big project, removing an old camp roof and building a new roof rotated 90 degrees, and adding a loft area. We were very happy with Andrew and his crew. They really go the extra mile to make sure everything is done right - they don't cut corners and take pride in their work. They installed new windows in the front and even used Windex to wipe off their finger smudges! Price was very good, and they're good, honest guys to work with. Very pleased!"

"I cannot recommend Drew Foley and Woodland Building Company highly enough! From start to finish, the experience was absolutely seamless. The crew is flat-out amazing—their talent is unmatched, and their craftsmanship is truly next-level. What really sets them apart, though, is their communication. Drew keeps everything incredibly clear and concise, so you always know exactly what to expect, when they’ll be there, and how the project is moving forward. If you want a team that is professional, remarkably skilled, and great to work with, this is it!"

"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!!"

Basement Remodel FAQs, answered by experts

Save money on your basement finishing project by making cost-effective decisions such as minimizing structural changes and avoiding costly construction revisions. DIY simpler tasks such as painting or basic cleanup to reduce labor costs. You can also opt for energy-efficient fixtures and materials that may qualify for rebates or tax incentives.

Building a bar in the basement will likely add value to your home, although it’s unlikely that you’ll see a significant return on investment (ROI) unless you plan on using the space for you and your guests. If you think you’ll use the area frequently, though, it’s probably worth the investment, and you should see a bump in value if or when you sell your property.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Framing a basement takes three to five days, on average, when completed by a professional, though it may take longer for a larger space. Keep in mind this doesn’t include the time to complete the design, obtain permits, and install the drywall on the framing. On average, fully finishing a basement takes an average of 45 days.

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.
