"The crew arrived earlier that agreed and set to work quickly. The crew were friendly, knowledgeable, respectful and efficient. They worked very hard and were very respectful of our home. The job required they work at our house over multiple days and each day the guys cleaned up the work area very thoroughly. I really appreciated that the guys did not rush any aspect of their job but really focused on the quality of their workmanship. All phone contact with the management of Cooper's Construction was answered very quickly and they were very responsive to our needs. I absolutely will use this company again and I will recommend them to everyone I know.

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

Walkout basements are not generally included in a home’s square footage, although they may be if they meet certain conditions that depend on local regulations. A finished walkout basement used as a living space may be counted toward square footage in some locations as long as all codes for livable space are met.

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board. Insulation with vapor barriers can help regulate temperature and prevent condensation. Consider using mold-resistant paints or coatings. 

Research and consult with experts to select materials that are suitable for your specific basement conditions and intended use. Prioritize quality and compatibility to achieve long-lasting and aesthetically pleasing results.

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.

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage.
