"We had our basement waterproofed in May 2019, the crew was out for 3 days. They also did some landscape grading. It's been 1.5 years and no problem. Very professional company. If I have any questions Carl or his wife, Jayna, respond promptly. I would highly recommend ABC for waterproofing a basement."

"We had the Steel City crew install the waterproofing system (French drain and sump pump) and wall strap in our basement. They are very friendly and efficient. They finished the project within one day and cleaned up everything. Then they walked us through and explained to us how to check whether the system is working. They also called us to check whether things are going well several days later. BTW, they have lifetime warranty! Very nice experience working with them and I would recommend to everyone!"

"Absolutely miraculous job! They turned our wet nightmare dungeon into a perfectly dry basement! Highest recommendation! We got floor drains, sheeting over our stone foundation, a sump pump and floor drain at basement door. Work was fast, professionally and was exactly what the basement needed."

"I would strongly recommend Kris Weaver and Baker's Waterproofing. Kris is extremely knowledgable about basement waterproofing, there's that. But he also did an excellent job of aligning scope and our budget. Baker's Waterproofing was highly recommended to us from friend and Kris exceeded all our expectations. He appears to be a top notch human being and we hired Baker's immediately. We are looking forward to getting started on the work and resolving our basement waterproofing issues."

I am extremely impressed with Rick in every respect. Most importantly, Rick is professional, honest, trustworthy, and knowledgeable, which is why I highly value Rick's input and feedback. Rick is always punctual and provides valuable and objective consultation and assistance. I would trust Rick for any job."

"Owner showed up with a small crew and a crazy new piece of equipment. Excavated down below my foundation and to the septic tank. Came into the basement and jackhammered the floor. Removed all the old terracotta pipe inside and out. Installed all new PVC pipe all the way down to the septic tank. Put gravel down to protect the new pipe. Poured concrete in the basement to close the floor back up. Only took one day to get the new pipe in. Came back the next to close the ground and floor up. Great experience, basement no longer smell like sewage."

Basement Waterproofing questions, answered by experts

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

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.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.
