"Brock came out for an inspection of my leaky basement and gave me the most thorough and honest report I?ve ever seen for this kind of work. I?ve had a few other projects completed in my house (roof repair, central air installation), and Groundwork?s is the first company where I don?t feel like I need to get multiple opinions. I trust them wholeheartedly and can?t wait to have a water-free basement thanks to them!"

Standard Water Control Systems is committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers interests, and make their concerns the basis of our business.

"Before you hire any Water Control company hire a plumber to make sure you really need drain tile. After we hired this company we still had seeping water issues. After they were called twice they finally told us we had a leaking pipe. In addition, an employee stole a cellphone and a FITBIT watch from our home and damaged our egress window. They fixed the egress window. The owner was not very pleasant, made us feel like we were not telling the truth. My husband literally spent hours changing passwords and canceling credit cards since the cellphone contained sensitive information. A few days later through Google find my device we pinned the cellphone at this business location, we called the police and had to take time away from our work to retrieve our phone. We never retreived our FITBIT watch. It was a nightmare! The company apologized but the damage was done!! The job itself was OK.. Apologies are not good enough after the hell we went through!! Watch who enters your property!! "

"Lewis Insulation came out for work on my home for ice dam issues. Lewis Insulation was to air seal our attic and add insulation. We decided to move forward. Lewis Insulation allegedly performed the work, but unfortunately the ice dam issues persisted. In short, we flushed thousands down the drain by going with Lewis Insulation. Xcel energy performed a home energy audit for us after Lewis Insulation performed the work. The Xcel home energy audit revealed that air sealing was missed during the air sealing process. After confronting Lewis Insulation, the team claimed some of these areas were inaccessible. This includes our furnace flue, which gives off a ton of heat in the winter. For those who may not be aware, this is egregious because of how much heat comes off that pipe. At no point did Lewis Insulation inform me that they were unable to air seal specific areas, including the flue. Lastly, they failed to insulate our basement rim joists properly. In short, we paid to have the team air seal our home and help with ice dams. They failed to eliminate the ice dams, and Xcel suggested we get our home air sealed again. I cannot recommend this company to anyone."

I really appreciate the way they thought through the problem holisitically and helped me to come up with a a reasonable plan. They also helped me to avoid some advice by a Basement Repair firm that would have not been helpful."

Basement Waterproofing questions, answered by experts

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

Mold growth is just one common sign of excess moisture in the bathroom. You may also see the paint in the room start to peel away from the walls, or that the walls remain wet for some time after you bathe.

Condensation on the windows is another sign that your bathroom has a potential moisture problem. The room itself may start to smell like mildew.

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.

Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn’t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn’t have any more issues than a slab or basement home.

Although waterproofing your basement may not directly increase the value of your home, it will protect the value you already have by preventing water damage. A basement without any signs of water will be more appealing to prospective home buyers. A leaky basement is a major red flag during a home inspection, and it will likely reduce the amount that buyers are willing to pay.
