"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!"

"Peter has great attention to detail and is extremely meticulous with his work. I felt that Peter went above and beyond with our deck remodel project. He was very consultative with the material selection and provided options and suggestions that most contractors would have overlooked. I highly recommend him and plan on using him again for future projects."

"The finished garage and mudroom addition was first-class, and has garnered a lot of praise by friends and neighbors. The work was diligent, and I was informed of all the work to be done by the contractor and his subcontractors. He was right on with the estimate and informed me if there were any changes and discussed them beforehand. I am very pleased with the job, and would recommend him to anyone looking for work on their homes, big or small."

"Ramy and his team did an amazing job with our flooring and the remodeling of our bathroom. The outcome was perfection and I couldn’t be more happy with the result. Ramy even helped me save on supply costs by helping me find great alternatives. He is the first person I’ll call for any projects coming up and I can’t recommend him highly enough."

Basement Remodel FAQs, answered by experts

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.

In many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.

Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms. 

Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.

Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.

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.
