"Thrasher did an excellent job repairing our driveway. They leveled out the entire driveway with amazing precision, and they fixed all the gaps with an attractive sealant that blends beautifully with the concrete. All of the team members I interacted with were professional and polite. I am very pleased with the results and only wish I’d called them sooner."

"Mike was prompt, efficient and professional during the estimate phase. He was very accomodating as it took a bit to secure the funds. When we were ready, he provided an approximate date to begin and end the work. His roofing crew was friendly, professional and hard-working. They listened to any questions I had and tried to accommodate us. Mike was in communication every day of the project and very interested in making sure we were completely satisfied. Because of the size of the roof, it became a two-day project and Mike was apologetic. We never considered it a problem and the crew started before 7:00 am every morning. There were a few extra things provided by Mike and his crew, some tree trimming, a couple of nails tidying up a sagging garage door and a little extra cleanup around the house. We are very satisfied with Agape Construction and wouldn't hesitate to recommend the for any project. You can trust Mike and his crew.

Basement Waterproofing FAQs, answered by experts

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

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.

Venting the crawl space can be a good alternative to encapsulation if you live in a dry climate and the moisture problem isn’t severe. You could also try a dehumidifier or install a vapor barrier on the floor, leaving the walls exposed. A new drainage system may eliminate the moisture problem if it is not caused by humidity.
