"We hired Groundworks to install a sump pump, expecting professional work and peace of mind. Unfortunately, the experience was anything but that. First, the team showed up 2 weeks after the initial visit. Worse than the delay was the complete lack of communication throughout the process ? getting updates or even basic responses was frustratingly difficult. The biggest issue, however, was the quality of the work. Their installation was poorly executed, and we ended up having to hire another company to fix their mistake ? costing us even more money on top of what we already paid Groundworks. We trusted them with an important job in our home and feel completely let down. I would not recommend Groundworks to anyone looking for reliable, professional service."

"Van Matre was truly outstanding from start to finish. Brady gave us an honest assessment of our situation and a number of reasonable options to choose from. He taught us a lot about foundations, and spent lots of time with us as we tweaked and tuned the plan. They were able to get us on their schedule fairly quickly, and they finished the job in about a week, which I thought was amazing. Willis, who led the crew, was super nice. He recognized our interest in the details of what they were working on, and kept us informed the whole way through. Joel, Wheelz and Adam were awesome too. They cranked through the work and left our finished basement just as clean as they found it."

Basement Waterproofing questions, answered by experts

Crawl space encapsulation can make repairs more complicated, particularly if you have plumbing or wiring surrounding your crawl space area. Additionally, some home designs benefit from the additional airflow that crawl spaces with vents provide. Vents are no longer an option after encapsulation. Always talk to your crawl space contractor to ensure the pros outweigh the cons before investing in the installation.

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.

It can be safe to live in a house with minor foundation problems as long as the issues are checked and monitored by a professional. Minor cracks are rarely a cause for structural concerns, but signs of leaks, sinking, or bulging walls should be strongly scrutinized by a foundation specialist. Similarly, it's always smart to hire a professional when you're concerned about buying a house with foundation repairs.

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.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.
