They take pride in their work and truly want the customer to be happy with the end product. I would hire them again if I need this level of work done again."

"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

Home improvements that increase value offer a high return on investment (ROI) and can enhance your quality of life. Upgrades to your home’s curb appeal often add the most value, with garage door replacement having one of the best ROIs at 93%. Other high-value exterior projects include replacing your front door, upgrading siding and roofing, installing a stone veneer, adding new windows, and landscaping. For interior renovations, a fresh coat of paint provides an excellent ROI. Major projects like a kitchen remodel or upgrading appliances and HVAC systems also add significant value, as potential buyers appreciate the peace of mind that new equipment provides.

Yes, it is possible to turn a regular basement into a walkout basement. Doing so involves excavating the land around at least one side of your basement foundation, installing retaining walls to create a permanent below-grade area outside your home, and then cutting into the foundation to install an exterior door that leads out to the new space. This is an expensive and time-consuming project, but it can add a lot of value and utility to your home.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

It is common for a contractor to ask for a down payment before starting a project, especially for jobs that require purchasing materials and equipment or hiring a crew. The deposit amount can range from 10% to 50% of the total job cost. While a request for up to 50% is not unusual, a contractor should not ask for more than that, and you should never pay for a project in full before the work has begun. To protect yourself, always discuss payment terms before starting and have a written contract that outlines the project timeline and expectations. Additionally, be sure to hire reputable contractors and check their licensing and insurance before the project begins.

Finishing a basement can provide a great return on investment, by increasing the market price of your home when you want to sell. Beyond that, there are many reasons to finish your basement. Doing so expands the usable square footage of your home, so you can enjoy it more, even as your family grows. Renovating your basement costs less in terms of time, energy, and money than having to search for and buy a new home.
