"Jamie called me back within minutes of my first inquiry online. He arranged to come out the following day and provided a quote. He was able to complete the roofing job in one day, arrived early, and stayed onsite for the entire day. He was thorough , professional, and straight forward in his assessment . He completed the job in a timely and thorough manner, along with a very complete clean up prior to leaving. Jamie came in just under his quote . I would certainly have Jamie do more work here, and hope he can help us in the future."

"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!!"

"Greg & his crew were very professional. Greg communicated exactly what the cost and date of completion would be. He updated us on a regular basis on how the project was moving along and finished ahead of schedule. I would highly recommend Innovation construction for your home project. We look forward to using Greg again on our next renovation. Tom & Denise Rooney - Bath, ME"

Basement Remodel FAQs, answered by experts

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.

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.

If you have the woodworking experience to build a bar from scratch and you have the time, DIYing the work is a no-brainer and can save a few thousand dollars. However, if you’re looking to include a sink, additional lighting fixtures, or high-end bar tops and cabinets, it’s usually a better idea to call in a pro. It will cost more, but the finished product will likely be worth it.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

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.
