Customers say: Quality work

"I think it's a testament to a company when you have such a great experience that you go back to them again for a second project. We worked with Bill and his team on a basement bathroom remodel 3 years ago and loved it. When it was time to finish the basement remodel and redo the flooring, windows and some lighting in the adjacent finished portion of the basement, I knew I wanted to work with him again. Bill is very easy going, but extremely knowledgable. He helped us through some material selection, provided sound advice on options and saw the project through to completion. I've personally recommended him to friends, and would absolutely work with him again on any other remodeling projects that come up at our house. Five stars, full stop."

"I couldn’t be happier with the work done on my basement remodel. The quality of craftsmanship, attention to detail, and professionalism were outstanding from start to finish. Everything was completed on time and exactly as discussed. Even came back fix a sticking door and made sure everything was perfect."

"Joe Timm did an extensive remodel of our 1965 ranch fixer-upper, that included kitchen, 2 baths, great room, 1 bedroom, and den. He was professional and thorough. His price quotes were on-target and reasonable. He was reliable: he called and visited when he said he would. We'll use him again for our unfinished basement. We highly recommend Joe and his work."

"We had Joe lay flooring in two of our bedrooms and he did an amazing job. Joe was incredibly professional, focused, and timely. He made sure to ask and answer all the right questions. Craftsmanship was fantastic. Would definitely recommend and will be hiring again when we have other projects in our house to complete."

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 most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Professional remodelers streamline the process, manage permits, and handle renovations efficiently—significantly mitigating risk while maintaining standards.

Costs are guided by renovation scope, materials chosen, project duration, structural needs, and labor. Prioritizing tasks prevents unforeseen expenses.

Yes, adding a walkout basement will usually bump up your property value. Most homeowners prefer walk out basements because the exposed wall that’s level with the ground provides more utility via a ground-level exterior entrance, and they can fit full windows, which adds natural light and ventilation to the basement area. The only exception might be in areas prone to tornadoes, as walkout basements aren’t as safe as regular basements during a tornado, particularly if they include large windows or glass sliding doors.
