Customers say: True professional

"I couldn't be happier with the work. Andy was extremely helpful and punctual. I had quite a few estimates on my kitchen remodel and I felt like none of the contractors I talked to were really interested in what I wanted. Andy listened to everything I had to say and delivered. 

Not only was the work completed on time. It was top notch work and under budget. How often does that happen?

I would highly recommend Andy Scott and would definitely use him again in the future.

"He just worked very tirelessly to get permits from city for slope of driveway. It was a lengthy and difficult process and he was the only one to take on this project. The work done was completely really well."

"My husband and I had spent 13 years remodeling our 1873 house by ourselves. When it came time to do our dream project of adding a sunroom, finding a contractor to do the work instead of doing it ourselves was a very important decision to us. We met with several contractors and knew instantly that John and his son Nate at Addition Doctors were the people we wanted taking on this project. John and Nate were so great to work with. They were the only company we met with who gave us a computer generated model of what the project would look like so we had a very clear vision of the end product. They were the only company to quote us the project under the budget we told them we had to work with. They kept us up to date at every step of the project and there were never any surprises about cost or timing. They had great ideas for the project when we weren't exactly sure what should or could be done. We love our finished sunroom. The quality of work and service they gave was excellent. We would highly recommend Addition Doctors for anyone who is looking to have quality work done to their home."

"Todd provided consulting of door specifications for a customer order door. He also completed the installation. The challange was the the opening would not allow for a standard door size. After we as the home owners had excavated & replaced the exterior basment steps it was was revealed that door frame work was not square and was impacted by the basement walls. Our house was built in 1925. Todd was able to view the exposed basement steps work prior to its completion. There was more than one site visit by him to determine the approach to installation for the door.Todd provided specs for us to order the door and met with us.& our vendor to review the specs before ordering. The installation went smoothly. Todd made no less than 3 site visits & many communications with us along the way. This was the 3rd time that we have used his services."

Basement Remodel FAQs, answered by experts

The time it takes to finish or remodel a basement can vary significantly, ranging from a few weeks to several months or even up to a year. On average, the construction phase can take four to eight weeks, but the total project time can extend to three or four months when including planning and permits. The timeline depends on several factors, including the basement's size, design complexity, the scope of the work, and your contractor's availability. A more detailed breakdown for an average-sized basement might include: framing (3-5 days), electrical and rough-in plumbing (3-5 days), drywall installation (5 days), flooring (2-3 days), and final touches like painting and trim (about a week). If preliminary work like installing a waterproofing system or addressing structural issues is needed, the timeline could extend to six to twelve months. Factors like difficult access, material transport, and ventilation needs can also add to the project's duration.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

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.

Save money on your basement finishing project by making cost-effective decisions such as minimizing structural changes and avoiding costly construction revisions. DIY simpler tasks such as painting or basic cleanup to reduce labor costs. You can also opt for energy-efficient fixtures and materials that may qualify for rebates or tax incentives.

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.
