From our first conversation with them, we knew that we could trust them to get the job done in our exact vision. They helped us to work within our budget and provided valuable insights and recommendations based on their experience. We’re thrilled with how it’s come out and won’t hesitate to use them for future home projects!"

"I needed to have the old flooring removed and the new flooring put down. They team was very professional. They realized the subflooring was messed up in a section and made sure to stop and communicate so the job can be doone correctly. I appreciated that factor and was able to approve a replacement of the messed up board the great thing was they were still able to finish the job in the time frame they originally stated! I plan to use them for all jobs moving forward. Priced fair,quality work, and friendly and professional!"

Basement Remodel FAQs, answered by experts

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

For most basement remodels, you’ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote. 

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

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.

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.
