Q: Why does my crawl space smell like a sewer?

• <div><p>A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor. </p></div>

Q: How do I make good drainage around my house foundation?

• <div><p>The best way to ensure the ground next to your home&rsquo;s foundation drains properly is to divert water away from it as much as possible. While a flood wall can stop water from entering the house, gutters and spouts can help direct rainwater and melting snow away from the foundation. Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house. Add extenders to the spouts so the water runs out and away from your home, not into the surrounding soil. </p></div>

Q: Is it OK to live in a finished basement?

• <div><p>Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted. </p></div>

Q: What are signs of a moisture problem in the bathroom?

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

Q: Does homeowners insurance cover basement flooding or water damage?

• <div><p>Standard homeowners insurance policies may cover basement water damage or flooding, but only if it is caused by a sudden and accidental event that is a covered peril, such as a burst pipe or a failing appliance. Damage caused by natural flooding from extreme weather, groundwater seepage, or heavy rain is typically excluded and requires a separate flood insurance policy. Some insurers also offer an optional water backup endorsement for issues like sewer backups. Review your policy or speak with your agent to understand your specific coverage.</p></div>

"Excellent work by Hunter K., Jacey H., and Teddy F.!!! I was so impressed with the encapsulation of my crawlspace that I immediately scheduled for the crew to come back and encapsulate my basement! They were very careful and attended to details, communicated every step of the process, made sure I understood what they were doing and why, and that I was pleased with the work. The space looks, smells, and feels amazing!!! Thank you to the best crew around!!!"

"I was very happy with the estimate I got from Corey, and he explained how things were going to be done. I had the waterproofing done on one entire wall of my basement, and a sump pump put in, on one of the coldest days of this year, and the guys were great, they put up plastic to keep things from getting dusty, and they were done in 1 day!! I was very impressed! I did have a tiny leak, a few days later, but the company sent someone out almost immediately, and that was resolved. I highly recommend this company, and know that I went with the best!!!"

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell.

Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house.

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.
