"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."

"They came to my residence and provided a cost and time estimate in a friendly neighborly manner. They stayed in touch to confirm our scheduled work date and time. They were punctual and thorough in explaining how the work would be done and listened when I commented on the locations of sprinklers and best approaches as to keep our lawn from unsightly track marks. The work was completed professionally as per our agreement. I would highly recommend them, and will use them for future landscaping work."

Basement Waterproofing FAQs, answered by experts

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Yes. Water can penetrate through a concrete foundation wall. This can happen whether or not you have cracks, as concrete is a porous material. You’ll want to take steps to waterproof your basement or crawl space.

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.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.
