Ohio businesses filed under foundation and waterproofing work, open and reviewed.
Roofers, plumbers and insulation companies with a side service were left out.
Services come from what each company says on its own site.
No answer on the site means "no information yet", never a guess.
Every listing starts from public business data for Ohio companies filed under foundation and waterproofing work. We kept businesses that are open and have Google reviews, merged duplicates, and left out roofers, plumbers, insulation companies and other trades that list waterproofing only as a side service.
Then we read each company's own website and recorded the services it names, such as wall anchors, piers, drain tile, sump pumps or crawl space encapsulation. When a site does not say, the listing says so instead of guessing.

A crack in a basement wall or water on the floor after a storm is stressful, and the first company you call may not be the right one. Some of the companies listed here mostly keep water out. Others mostly fix walls and foundations that have moved. Many do both. This guide covers what to look for before you sign anything.
Water coming in is usually a waterproofing job: drain tile, a sump pump, sealing cracks or encapsulating a crawl space. Walls that bow, floors that sag or doors that stick point to a structural problem that calls for wall anchors, braces or piers. A good company will tell you which one you have after an inspection, and many listed here say they offer that inspection for free.
Weather plays a part. Yearly precipitation averages about 32 inches in northwest Ohio and 42 inches in the south, and 2-inch downpours have become more common since the mid-1990s. Forecasters also expect wetter winters and springs, which raises the risk of spring flooding.
Ohio's state contractor license covers HVAC, refrigeration, electrical, plumbing and hydronics work. Foundation repair and waterproofing are not on that list, so licensing is mostly a city matter. Columbus licenses home improvement contractors for structural work and lets you search for a contractor online. Cincinnati requires every contractor working in the city to be registered. Cleveland requires contractors to be bonded, insured and registered, and you can call 216.664.2910 to check. Toledo requires home repair contractors to hold a city license. Ask every company which local license or registration it holds, and check it with your city before you pay a deposit. The listings on this site show whether a company states a license on its own website. This site does not check licenses.
Permit rules differ by city. Cincinnati, for example, lists building repair and excavation as work that needs a permit. Ask the company who pulls the permit, and call your city's building department if you are not sure. If the job means digging outside, such as exterior waterproofing or drain tile, Ohio law requires the excavator to notify OHIO811 at least two working days, and no more than 16 calendar days, before digging starts. Call 811. The call is free, and a hired contractor must place it before digging.
Each listing shows the services a company names on its own website: foundation repair, basement waterproofing, bowing wall repair, piers, crack repair, crawl space work, sump pumps, drain tile, concrete lifting and egress windows. It also shows whether the company mentions a free inspection, financing, a license or a warranty. A service under "No information yet" means the company's site does not say. It does not mean the company does not offer it. Call and ask.
Ask what they think is causing the problem and how they know. Ask what the warranty covers, whether it is in writing, and whether it transfers if you sell the house. Ask who does the work, their own crew or a subcontractor. Get at least two written estimates that describe the same scope of work, so you can compare them line by line.
Each listing is an open Ohio business with Google reviews that does foundation repair, basement waterproofing or crawl space work. Roofers, plumbers and other trades that only list waterproofing as a side service were left out. Owners can claim a listing to fix details or add photos.
No. A basic listing is free. Companies can pay for a featured spot or a premium listing, and those are always marked as featured.
No. A listing shows whether a company states a license on its own website, but nothing here is verified. Ask which local license or registration the company holds and check it with your city before you hire.
Waterproofing keeps water out of a basement or crawl space, with drain tile, sump pumps, crack sealing or encapsulation. Foundation repair fixes walls and footings that have moved, with wall anchors, braces or piers. Many companies here do both. Each listing shows which services the company names on its own website.
Ohio's state contractor license covers HVAC, refrigeration, electrical, plumbing and hydronics work, not foundation repair or waterproofing. Many Ohio cities, including Columbus, Cincinnati, Cleveland and Toledo, require contractors to be licensed or registered locally. Ask which one the company holds and check it with your city.
Ohio law requires the excavator to notify OHIO811 at least two working days, and no more than 16 calendar days, before digging starts. Call 811; it is free. If you hire a contractor, the contractor must place the request.
