"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."

"They did a great job installing French drains and sump pump in our basement. Great communication! They changed work plan to cater to our needs and got it done in one day, staying until it was finished. Very reasonably priced!! Highly recommend!!"

"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."

"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."

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 questions, answered by experts

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

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.
