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."

"The quality of work was great and I love my new basement. There were a few schedule delays, some that were poorly communicated and led to contractors arriving at the house unable to do work."

"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."

"We selected Investment Painting Contractors because of their ad in the Angie's List monthly publication sent to our home.  Len (owner) came to our home to assess the situation and he gave us a proposal (including a 5% Angie's List discount).  At that time we also selected paint colors.  The following Monday work started on our kitchen and bath.  Each day Len, Ed and Theron appeared at our home at exactly the time promised.  During the time they worked in our home they were friendly and very professional.  They worked hard and demonstrated pride in their work.  Upon completion of their work, we were extremely satisfied with the results.  They did a beautiful job, and we would highly recommend them.  We plan to enlist their services for any painting done in our home, and we have recommended them to friends and family.

Basement Remodel FAQs, answered by experts

Any bowing in a basement wall indicates a problem that needs to be addressed by a professional. If your basement wall bows more than 1 inch, it's time for an inspection. Generally, a wall can bow up to 30% of its thickness (around 2.5 inches for an 8-inch-thick wall) before it becomes an urgent situation. Bowing of 2 to 4 inches is more straightforward to fix than bowing of more than 4 inches, which will require significant repairs. If the bowing is more than 6 inches, the wall will likely need to be replaced. The sooner you address the problem, the easier and less expensive the repair will be.

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.

For most basement remodels, you’ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote. 

Renovations that add functionality or more comfortable floor space generally add the most value when remodeling your home. Attic or basement finishing can add floor space without altering the home's structure, saving you renovation money while adding valuable space. Smaller improvements, such as installing smart-home components or replacing entry doors and windows, also experience high ROIs. 

You technically can paint wires in a basement ceiling, but there are several important safety and code considerations. It's safe to paint non-metallic sheathed cable as long as the labeling remains visible. You can also paint low-voltage wires and conduit and junction boxes to help them blend into your basement. 

However, you should not paint damaged or deteriorated wiring is a fire hazard because it poses a fire hazard. The same goes for painting over high-heat wires that connect to heat-generating appliances or systems. Be sure to avoid painting multiple coats onto any wires, as that traps heat and poses fire risks.
