"Our sewer service between the city and the house failed due to poor materials when the house was built in '95. Once it was all exposed, it was easy to see what a poor system a less caring plumber had installed. Vince and company replaced it all quickly and easily with the proper materials. We use Vince exclusively for all of our plumbing needs."

"Well. 1st plumber who looked at the system said shower valves needed to be replaced but that was a problem because there are no access panels. Chaub plummer advised valves were good quality and there was no need to replace. He replaced/installed new hardware and did a great job in a timely manner."

Basement Waterproofing FAQs, answered by experts

Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there’s a lower chance of dust mites breeding and causing allergic reactions in your home.

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

Plan on cleaning your crawl space at least once a year, though twice a year is ideal. During the cleaning, remove any debris or dust and check for potential issues like pest infestations or water damage. The sooner you catch these issues, the easier (and cheaper) it will be to fix them.

Access to commercial-grade products and equipment, ensuring thorough coverage and long-lasting protection.

Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile.
