"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."

"Brett and his guys have run gas lines, installed faucets, changed out water heaters, replaced outside spigots and plumbed washer dryer hookups for me. The work is always started in a timely frame, work was done properly. The best part for me is that they always leave the job site clean."

Basement Waterproofing questions, answered by experts

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

If not properly maintained, an underground downspout may damage your home's foundation. A clogged downspout can back up, causing water to pool around the base of your home and seep into the foundation. Regular inspections and maintenance keep your downspout in good working order, preventing damage and protecting your home.

A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.
