"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 questions, answered by experts

A crawl space is an area under the house that provides access to plumbing, electrical, heating ducts, and other HVAC units. Its purpose is to create a buffer between the ground and the living area, helping with ventilation, moisture control, and access for maintenance or repairs. Crawl spaces are most often seen in houses in North America which are built on concrete foundations versus other parts of the world where buildings are constructed differently.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

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.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.
