"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."

"We had a great experience working with Wes from Boynton Builders LLC! We had a pretty extensive basement remodel / conversion to living space project that we needed help on, and we are extremely happy all aspects of this project using Boynton Builders LLC. Wes responded quickly to a voice message I left, was able to quickly schedule a time to visit to discuss our intended Scope of Work (which also involved another project re-enforcing a carrying beam and support post in our detached garage) after which he quickly provided detailed quote that fortunately fell with our budget. We agreed to move forward, and Wes went to the Town Office for us and took care of the Building Permit and were able to start our project within a couple of weeks and the work proceeded at a good clip with every stage discussed being performed in the order identified from the onset. As the project progressed, we added an additional phase to the scope of work (Install Flooring and a new double door) and he quickly estimated the additional cost got the next phase into his schedule about a week after the completion of the first / original project. Throughout the whole project Wes was pleasant, professional, motivated and productive and open to any requests for change as the space began to be completed and new ideas came into play as we were better able to visualize the final result. Wes completed all of the work on time and within the budget/ and additional scope estimates. We already have the next project planned and will be using Boynton Builders LLC again. Any friends that have seen the completed project state that it is "an incredible transformation" and we are proud to welcome friends into a space that was once an embarrassment. I would also like to mention that I originally reached out and left the same voicemail (one right after the other) for three different contractors and Wes was the only callback received, and that was within a couple hours."

Basement Remodel FAQs, answered by experts

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.

Costs are guided by renovation scope, materials chosen, project duration, structural needs, and labor. Prioritizing tasks prevents unforeseen expenses.

To determine if your basement walls are suitable for finishing, assess their structural integrity and moisture conditions. Look for any signs of damage, such as cracks, bowing, or excessive moisture. Ensure proper drainage and address any underlying issues before proceeding. 

Consult with a professional if you're uncertain about the structural stability or potential risks associated with finishing your basement walls.

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

Joists and beams are both part of the flooring system above your basement, with the beams spanning the length of your home and getting support from vertical posts underneath, and joists usually spanning half the width of your home with no support posts underneath. The floor joists provide even support to the subflooring and flooring above, and they distribute that load to the beams. The beams then distribute that load down through the support posts to the foundation.
