Award winning local contractor! Our areas of Expertise...

"Jeff came out and did exactly what is advertised on their website: inspected and educated. Excellent service with a depth of knowledge. My wife and I have owned a house for almost a couple years now that is 62-63 years old with a crawl space. It had some foundation work done sometime before we took ownership and we just wanted some peace of mind that everything was still solid. Jeff came out and ended up just doing a cursory inspection since my wife and I didn't need anything official, just a professional eye. I followed Jeff around as he was pointing things out. Thankfully there was nothing of concern, just points of interest, and a lot of education. At the end of it all, my wife and I are much more confident in the backbone of our house thanks to Jeff and the Foundation Professionals of Colorado."

"We paid them $9356.26 as 60% down to complete a sliding glass door installation and patio enclosure. After 2 months of being given the run around. We have two projects started and neither completed. They provided us with maybe 12 hours worth of work. They are no longer showing up to work or returning our phone calls. We were told by the company that they were bankrupt and used our money for another job. They said we no longer have your money. They still have their website up and have their phones listed as Risen Contractor Group. Do not hire!"

Basement Waterproofing questions, answered by experts

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

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.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.
