"We had seen Duane's work and got a quote. We had the kitchen totally remodeled. Duane had a couple suggestions which made the whole project better and did not wreck our budget. The work and crew that preformed it were absolutely great. Duane was accessible if we had a question and got the project completed in a timely manner and at the price agreed on. We love our new Kitchen and highly recommend Duane and his crew. Thank You Guys."

"Awesome finish work to our tiny remote cabin! Ryan and crew installed our LVP flooring in just a few hours. He kept us up to date on the project with text and pictures, super helpful since we live in Seattle and had to work. His crew kept the construction site clean and the vendor he used for our cedar interior work was meticulous. Thanks Ryan!"

"We had a very good experience working with Pro Image, We started by getting an estimate from another firm. The representative of that firm was always late for meetings with us, took a long time to get us their estimate, and the estimate was much higher than we expected. The experience with Pro Image and its owner, Kevin, was much different. Kevin was on time for the first meeting, and every meeting after that. We got the estimate within a day or two, and it was much more reasonable. They remodeled a bath, a family room, a laundry room, and a bedroom, and the work was great. The remodel was not simple, because they framed in new ceilings in 3 of the rooms, modified several windows and door sizes, and framed out two walls in the bedroom to hide the foundation. They made great suggestions on materials and people to work with that made the process go very smoothly. The work was done on time and within the original estimate. Kevin and all of his crew were friendly, courteous, and efficient, a joy to work with. So much so, that we have already hired them for an additional job."

Basement Remodel FAQs, answered by experts

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

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.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.
