Groundworks knows how to solve basement, and crawl space problems, the first time. Proudly serving Montana and Wyoming.

"WOW! Groundworks is a great, reliable company! We had the dream team, Ryan, Alejando (Alex) and Jose, working on our home. Ryan kept us informed on what was going on the during the whole project. Ryan and Alex were so reassuring of all our fears and concerns, we knew we were in good hands. Alex and Jose were so polite and talk about hard working!! All three of them went above and beyond, exceeding our expectations, saving some landscaping we didn't expect to be saved. They took great care with our landscaping and yard and did not cause any unexpected damage to any of it! They did a great job with the clean-up at the end of the job as well. These three men worked great together as a team. We were happy to see them everyday and a little sad when we said good bye."

Basement Waterproofing questions, answered by experts

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

Typically, waterproofing a basement should last up to 10 years. However, it’s worth noting that with proper maintenance and depending on the waterproofing method and installation quality, you can probably squeeze another decade out of it.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

Below-ground shelters are the best in terms of durability, but there is a risk of flooding and obstruction. Modern technology and rigorous construction requirements make above-ground shelters a better option for accessibility, safety, and, usually, your budget. They may not have the same aesthetic appeal, but many of their features make above-ground shelters a better option. 

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.
