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

"My certified inspector MatthewCote out of the Belgrade, MT office found i have a natural spring comming up in my crawlspace. I knew I had water streaming all over crawlspace and my husband believed it was due to watering lawn of the hill our house sits on. Matt was great to work with, he was totally professional. He explained my situation and showed me in photos and map of my basement what this ssprincause, how it had eroded and damage caused. It has been going on for quite a few years, of which I noticed escalation of water even though I decreased watering on above lawn. I wish I had researched this sooner. But MATT assured me it's not too late. He was clear and concise as to what I needed done to resolve and eliminate further damage by installing 2 sump pumps, installing trenches & piping to drain all areas of water, draining ouside of house past septic and leach field, add a humidifier and encapsulation of crawlspace. I highly recommend Groundworks and Matt to anyone."

Basement Leak Repair questions, answered by experts

You may have to dig out drain valves if they are buried under dirt. This method isn’t ideal, and it increases the chance of clogs and damage. Ideally, a drip irrigation system buries drain valves in a gravel pocket so they are easier to access and better-protected. If you have trouble accessing drain valves, hire a sprinkler professional to find them safely and efficiently.

Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don’t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
