"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

When a backflow valve fails, wastewater will flow back into your system, contaminating your drinking water. You’ll immediately notice backflow valve failure from a rotten smell and brown water coming from faucets. Get in contact with a septic pro or a plumber immediately if you suspect this has happened to you.

Yes, many contractors offer warranties for their work. Confirm terms before starting the project.

In some cases, operating a snake can damage your drain and pipes. This depends on the overall condition of your pipes and how gently you operate the auger. For instance, older galvanized pipes covered in zinc are susceptible to scratches when using a drain snake. Additionally, it’s common for newbies to apply too much force when extending the snake, leading to scratches and related damage. You can also crack the porcelain with an electric auger if you’re snaking a toilet drain. If you’re using a manual snake or auger, the risk is minimal.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:
