"Brian LaValle is a God Send!! Bought my home for under 20k and Brian has done everything from the basement to the roof!!! Drive by and Look at It. 705 Lundy St Streator. It sat for 5 1/2 years after a destructive foreclosure. There was no bathroom! Everyone Loves my bathroom now. The house looks Modern and heâ  s SO professional and comfortable and has been working on my home for well over a year so we pitched him keys to the house. I slept in the other day while him and his crew, always making sure my cats donâ  t get out, installed my laundry room floor. Never thought something like that could happen! Grade A work! Im So Proud of my house! This guy Checks My House to assure itâ  s sound and safe! The addition was attached to the original house. My roof was stressed and leaking. He â  tiedâ  (their lingo) the 2 lil houses together. Now Iâ  m saving up for him to do the roof. I flipped and remodeled 4 homes of my own when I was younger. This guy is the best. I humbly admit.

"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

Yes, you can add a door to your basement—it might even be required, depending on building codes in your area and whether or not you’re using the basement as a bedroom. A basement contractor can give you some advice on installation and help you add a door to your basement.

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board. Insulation with vapor barriers can help regulate temperature and prevent condensation. Consider using mold-resistant paints or coatings. 

Research and consult with experts to select materials that are suitable for your specific basement conditions and intended use. Prioritize quality and compatibility to achieve long-lasting and aesthetically pleasing results.

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.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

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.
