Wonderful job on both the painting for the development, and the staining of my deck. Probably the best quality painting that we have ever had in our development. From the beginning, the work, work order, estimate process, etc. was handled in a top knotch way. I have had a number of contacts with the company's owner, Colby, and he has shown himself to operate a well run company.He is very businesslike, returns calls promptly, and has people there when he promises.  I also had dealt quite a bit with Josh, who directly supervised the overall process. Josh is very cooperative, understanding, and very helpful. He always came through on his committments, and it made for a very pleasant experience.


The painting crew, led by Arturo, was by far the best group of painters we have used. I got many comments from other homewoners in the development who were very impressed with their work. They are meticulous in what they do, and the final product shows it.

Basement Remodel FAQs, answered by experts

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

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.

A finished basement does not always count as square footage, as this varies by state regulations. In areas that allow below-grade spaces to be included in a home's official square footage, the basement must typically meet certain conditions. These conditions often include having a functional egress and being a livable space with flooring, finished walls, and temperature control. To be certain, contact your local assessor to confirm your area's specific policies regarding basement square footage.

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.

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.
