"Oh we can't say enough about Rueben and his crew.. the work was top notch and talk about craftsmanship, there is no comparison.. we were on a budget and they came through and made everything work. We had a sunroom and bath added to our h ome and we just love them. The crew of guys were always very polite and just a great group of young men doing the best job we could of imagined. Ruben was always on top of the job, making sure things were done right. He came every day to check on his crew and asked if we had any concerns. So on that note if you need any construction on your home or business give this company a call, you won't be sorry."

"It went well.. we had water in our basement and had to have some work done in order to get it back to where it was. Ken came in early may to start the job and took the bar out and and the drywall that was wet. He then had to come back after we got the asbestos out of the basement. He did a great job and I would use him again. He put in new electrical and drywall and put our bar back.. there were some issues with the bar not being level but he came back with no argument to fix it. Drywall looks great

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.

"Amanda was really very good!  At first I was very skeptical, thinking why did I pay money to just speak with someone on the phone about my kitchen remodel project... but after just a few minutes of her addressing some of the issues/questions I emailed to her earlier, I knew it was worth it.  It was very clear that she knew her business and she gave me several ideas that I had not even thought about.  I told her that I would definitely recommend her to friends and I will very likely use her again myself for my next home project!

Basement Remodel FAQs, answered by experts

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Yes, in most cases, finishing a basement is worth the cost. The project adds valuable, usable square footage to your home and typically provides a return on investment (ROI) of 70% to 75%. For example, an average basement refinishing project costing $32,000 could add between $22,400 and $24,000 to your property's value. The final value added depends on factors like your location, the quality of materials and workmanship, and the features you include, such as a living space, bedroom, or bathroom. To be officially counted in your home's total square footage, the finished space must comply with all local building codes, including requirements for points of egress. However, in areas prone to flooding, a finished basement might be seen as a liability by potential buyers and could potentially decrease your home's value.

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

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.

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.
