"Tal Mechaly was extremely useful when we hired him and his people to design and rebuild our new kitchen and laundry room. Tal helped us select the new stunning marble slab for the new island that he implemented in the design and the gorgeous chandelier above it because the island that he designed for us included table as well. Tal Mechaly was amazing at selecting all the paint colors combinations and with his design… he was able to pull it all together as one piece of art kitchen. Tal Mechaly was very easygoing person to work with, with excellent creativity skills and his thinking outside of the box ability was beyond believes."

"I met Mike, the owner of BMO Kitchen and Bath, and his team 8 years ago when he was doing a kitchen and bath remodel at my daughters house. We were all very happy with the work they did and decided to hire Mike and the BMO team for a full remodel of our home. This included remodeling the kitchen and 3 bathrooms, installing new cabinets, new plumbing new lighting and new flooring throughout most of our house. When we could not find cabinets to fit, Mike built beautiful cabinets himself. 7 years have passed since this remodel was done and everything Mike and BMO did still works great and looks great. We found Mike to be very honest, knowledgeable, reliable and easy to work with. He respected our opinion and was always available to give us his thoughts on how to improve our project and what products to use. We have been so please with Mike and the BMO team that we have used them for all construction and repair jobs since that time. We have also happily recommended Mike and the BMO Kitchen and Bath team to all our family and friends. They are very knowledgeable, very professional and a pleasure to work with."

Basement Remodel questions, answered by experts

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.

The cost of finishing a basement is about $18,400 on average. As you can see, the framing portion of this project costs less, because you’re essentially just dealing with laying the foundation for a finished basement. The finishing portion of the project involves a lot more intricate work and design, as well as high-end materials.

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.

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

The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing. 

If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
