"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."

"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."

"Pete & his crew took our extremely sloped, wet yard, and created a dry, level area that is perfect for us. We never thought the yard could or would look this good, but Pete has a great vision and also has the ability to make it into a reality. Pete is honest, and exceeded our expectations. We could not say enough about the positive experience we had with Pete & his crew. Highly recommend."

Basement Waterproofing questions, answered by experts

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.

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 keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

A sump pump can remove excess moisture from under a house if standing water is present. Other ways to protect your crawl space from moisture include installing a vapor barrier, using a dehumidifier, installing insulation, and using a fan to dry the space. Finally, keeping your gutters clear of debris and positioning your downspouts away from the home’s foundation can prevent moisture from getting into the crawl space in the first place.

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.
