"My old water heater went out yesterday and of course leaked water all over. I shut it off and stopped the leaking. Called early this morning looking for someone to install a new one. Jim was actually sent over by another plumber who could not get to my job right away. Jim showed up, looked at the job, we talked about the options and he gave me a bid. Let to get the new water heater. We back in about thirty minutes. He had to make some changes to the water and gas lines. Added shut offs and installed new one. Took the time to explain operation and maintenance of the new one. Cleaned up the work site. Removed all debris and old water heater. I was impressed with his work and his attitude.

Basement Waterproofing FAQs, answered by experts

No, everything doesn’t get wet if the bathroom is well-designed and the fixtures are properly installed. It’s important that the floor of a wet room drains correctly, and proper waterproofing and slip-resistant flooring are used to avoid creating slipping hazards. Since the shower isn’t housed in an enclosed space, you’ll need to make sure the towel rack and toilet paper holder are placed in areas where they won’t get wet.

Periodic inspections and addressing drainage issues prevent further damage.

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.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.
