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.

"The work was to our expectation. The living room addition was done to our taste and fitted very well with the reast of the house. The egress window installation to the basement room gave a whole new life and vibrancy to the rooms downstairs. Our kitchen now looks great after the remodelling.Neil and all his team were very respectful and professional. Everything went to our expectations and I would highly reccommend him to anyone who needs some work to be done!"

"I am thrilled with my Bathroom- they showed up when they said they would. They listened to my requests - went into the project knowing what the end goal would be. The bill was what they quoted. They cleaned up after themselves. Great customer service and outstanding workmanship."

Basement Remodel FAQs, answered by experts

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.

Professional remodelers streamline the process, manage permits, and handle renovations efficiently—significantly mitigating risk while maintaining standards.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

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.

The average cost to remodel a basement is between $12,100 and $33,400. Depending on the project's complexity, the price can be as low as $3,500 or exceed $50,200. For a simple project like adding a home office, you might spend between $500 and $3,000. However, a more extensive project, such as adding a bathroom, can range from $6,600 to $16,500. The final cost is influenced by factors like the basement's size and condition, the type of remodel, material choices, your location, and accessibility. For an accurate price, it's best to consult with a basement remodeling team.
