"We found that the wall in our laundry closet was soft and damp. After opening the wall a bit we found massive water damage. Ray with Lopez Bros Construction responded quickly to our request for quote, came out and assessed the damage, and gave us an idea of what it would cost. He then pointed out the demo work that was needed and offered to allow us to do what we could of the work to save us money. Once the demo work we could do ourselves was done, Ray and his crew came out to complete it and then identify where the leak was. This had clearly been going on for some time as the entire floor and subfloor was completely rotten. Ray coordinated the plumber to fix the leak, remove the water heater that was in the garage on the other side of the laundry wall as it was pressing through the other side. After allowing several days for everything to dry out, Ray and his crew then began building back the floor and the walls. Work was completed within a week. Everyone was professional and careful to keep the mess to a very minimum. Ray communicated everything he found, his plan to fix, and showing progress throughout the project. He always let us decide how far to go (removing the water heater and repairing the other side of the wall was our decision) and never pressed to do any more than what we were comfortable with. The project was much bigger than expected, but the price of the work wasn't much more than what was originally discussed. SUPER happy with Lopez Bros work!"

"I strongly recommend Bzr. We found them on Houzz. We started with a kitchen remodel and felt good about moving forward with our next projects with them. We then started our bathrooms. Sean and his crew did an amazing job. They were very respectful about our place, patched up and protect our home. Sean was very helpful with choosing and delivering materials. Overall we had an outstanding experience with them. Gaby was also such a pleasure to work with. Without a doubt we would hire them again."

Basement Remodel questions, answered by experts

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.

Yes, you can add a door to your basement—it might even be required, depending on building codes in your area and whether or not you’re using the basement as a bedroom. A basement contractor can give you some advice on installation and help you add a door to your basement.

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.

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. 

Renovation enhances functionality, increases home value, and can add new space for personal or family needs. It typically modernizes older unfinished basements for new uses.
