"We hired McCormick Home Builders to remodel our living room, and we are beyond pleased with the result. The team was professional, worked efficiently, and Aris design ideas made a huge difference. The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

We did a herringbone pattern on the back wall as well as a large niche. The side walls are a marble tile and we did a single slope shower pan to a line drain on the floor with a small glass hex tile.
The Shower
We build up this tub deck to match the new cast iron tub that was installed. We surrounded it in a 12x24" marble tile.

Basement Remodel questions, answered by experts

It’s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is $32,000 (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

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.
