"I am 64 years old and have never done an online recommendation previously. I am in this instance due to their superior performance on my basement waterproofing and wall anchor project. Everyone affiliated with the company personified competence, conscientiousness and customer service. Have never had a better customer experience-could not recommend them any more highly."

"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!"

"Real Pros. They arrived a tad early and I asked them to not start pounding out the basement floor until 8 am. At 8:01 they started. French drain Project finished completely at 12:15. I’ve waited until the next big rain which happened on Monday am. Torrents of rain and basement is bone dry. Exactly as promised."

Customers say: Super punctual

"The quote was fair and the work was done in a day (several guys on the job). They hand dug the trench to minimize yard damage and to prevent removing my new fence. The drain runs from my backyard all the way to a pop drain next to the street (about 90ft). They re-used sod where they could and used peat moss and grass seed to re-plant the backyard (which was a mess due to water build up and mud). That was early April and now you cannot even tell they were there. The yard looks great and the water problem was solved. I waited to see how the drain would handle the spring rains before writing this review. Happy to have a usable yard again!"

"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 FAQs, answered by experts

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

To maintain an outdoor structure, perform regular inspections for damage, leaks, and weak joints. Clean the structure regularly, treat or repaint wood surfaces for weather resistance, and reinforce any weak joints to prevent deterioration and ensure its longevity.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.

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.

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.
