"I was so happy with my previous bathroom remodel from Extreme Makeover I hired John again to do another Project on the upstairs bath. Again, the results were better than I anticipated. John Leahy, owner and his associate John produced a beautiful and updated look. The craftsmanship was impeccable and they were always on time and finished the project earlier than promised. John is very courteous and approachable and is easy to relate to. I know you will be very pleased with Extreme Makeover for your next home project."

"We hired Tom for a kitchen & half-bath remodel in 2019. As with all remodeling projects, especially a kitchen remodel that disrupts your life, Tom was wonderful at communicating and kept the project on time and on budget. Tom stands behind his work and quickly remediated any issues (which are always inevitable with these projects) and we can absolutely say that we are still 100% satisfied a year later. We completely trusted Tom to make our kitchen remodel dream come true and would hire him again should another project come up!"

Customers say: Quality work

"From start to finish Steve was friendly, professional and had no problem helping us through every step of the process. Steve managed to keep the job site meticulously clean, kept to his promised timeline and was mindful of our budget. He has a great artistic eye and was able to make necessary design changes that took the job to the next level. The fireplace he installed is a STUNNING show piece with a complete shiplap surround, a beautiful handmade wood mantle, custom iron brackets and shiplap that continues across the entire back living room wall. Steve's attention to detail, talent and care for what he does shines through and we couldn't be happier with the end product! We are excited to have him continue our renovation process by remodeling our kitchen and other living space projects. We would highly recommend Steve to anyone we know. We were lucky to find him!"

Basement Remodel questions, answered by experts

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.

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.

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.

A finished basement does not always count as square footage, as this varies by state regulations. In areas that allow below-grade spaces to be included in a home's official square footage, the basement must typically meet certain conditions. These conditions often include having a functional egress and being a livable space with flooring, finished walls, and temperature control. To be certain, contact your local assessor to confirm your area's specific policies regarding basement square footage.

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.
