BASEMENT WATERPROOFING · LIMA, OH
Basement Waterproofing in Lima, OH
We keep water out of basements and crawl spaces for homeowners, landlords and property managers across Lima and Allen County. Lima was built on drained swamp, and the clay under most of the city holds water instead of shedding it. That means a wet basement here is not bad luck — it is the ground doing what it has always done. Licensed local crews, fixed-price written quotes, and repairs matched to what your foundation is actually made of. Call (419) 731-9193 for a free on-site inspection.

LOCAL EXPERTS
Basement waterproofing built for Lima's ground
There is a reason Lima basements behave differently from basements an hour away. Northwest Ohio sat under the Great Black Swamp until the nineteenth century, when it was artificially drained for farming and settlement. That drainage is engineered — ditches, field tile and pumping — and it holds only as long as it keeps working. Underneath the city is clay loam over glacial till, and the Allen County soil survey documents the seasonal high water table within about six and a half feet of the surface. Most basement floors sit deeper than that. Water does not soak down through clay. It perches on top, spreads sideways, and finds the lowest opening it can reach. We work in that ground every week, and we quote what your foundation actually needs rather than the same system on every house.
WHAT WE DO
Our basement waterproofing services in Lima
Interior Drainage & Sump Pumps
Drain tile below the floor, routed to a sealed sump basin with a bolted lid. The right answer for a perched water table.
Block Wall & Foundation Repair
Hollow block holds water inside the cores. We repoint the joints and drain the wall instead of injecting a crack that is not the problem.
Exterior Waterproofing & French Drains
Excavation to the footing, membrane on the wall, perforated pipe in washed gravel. The most permanent option, and sometimes the only one that works in clay.
Crawl Space Encapsulation
Reinforced liner fastened at a termination strip with every seam sealed, plus a dehumidifier sized to the space. Not a sheet of plastic on dirt.
Basement Waterproofing Cost
Real price ranges for every service on this site, published openly so you can see the numbers before you call.
Not sure which repair you actually need?
Most homeowners call us after getting a quote that felt too big for the problem. A free on-site inspection tells you what is happening in your wall, what is causing it, and which of these services is the right one , from
crawl space encapsulation to interior drainage & sump pump— including when the honest answer is the cheapest one on the list.
how we work
How a Lima waterproofing job actually runs
Diagnosis comes first and carries the most weight. Two basements on the same street can take water for entirely different reasons — one from a perched water table pushing up through the slab, the other from a downspout dumping against the wall. Getting that wrong is how homeowners end up paying for an exterior excavation when a gutter extension and drain tile would have solved it. Here is the sequence we follow on every job.
01
Diagnosis
On-site inspection of the wall, floor, grade and drainage to find where the water enters and why.
02
Written fixed price
A written quote with a fixed number, scoped to the diagnosis. No pressure to sign that day.
03
Permits
We pull the Allen County plumbing permit before work starts, because a sump installation legally requires one.
04
Protection and setup
Floors covered, contents moved, dust containment set. Concrete cutting is messy work and we plan for it.
05
Installation
Drain tile, sump, repointing, membrane or liner, whatever the diagnosis called for, installed to spec.
06
Inspection and walkthrough
County inspection signed off, system tested with water, and we show you how it works before we leave.

WHY CHOOSE US
Why Lima homeowners call us instead of a franchise
- Local crews, not a truck dispatched from Toledo, Dayton or Fort Wayne
- Registered with the City of Lima and licensed for the plumbing work a sump requires
- Fixed-price written quotes based on an on-site diagnosis, never a phone estimate
- Repairs matched to hollow block construction, which is most of Lima's housing stock
- Real cost ranges published on this site before you ever call
Lima sits at the intersection of I-75 and enough interstate distance that most of the big waterproofing companies serving this market are driving in from somewhere else — Toledo is 78 miles north, Dayton 72 miles south, Fort Wayne 63 miles west. Those crews are competent, but they are not going to know that five lowhead dams inside the city limits hold the water table artificially high near the impoundments, or why a house in Shawnee Township behaves differently from one on the north side. They also will not be here in three years when a pump needs a float switch. We live here, we work here, and the same person who quotes your job is the person you call afterward.
WHERE WE WORK
Where we work in Lima and Allen County
We cover Lima and the surrounding townships and villages: Shawnee Township, Bath Township, American Township, Elida, Bluffton, Delphos, Spencerville and Allentown. The Lima metro area is home to roughly 102,000 people, and the housing across it varies more than you would expect for a market this size — oil-boom homes from the 1885 to 1930 era with brick and rubble foundations, and a large stock of war and postwar homes on hollow concrete block.
Where your house sits matters as much as when it was built. Homes near the Ottawa River impoundments carry an elevated local water table year-round, while houses a few streets away on higher ground stay dry through the same storm. That is why we inspect on site rather than quoting over the phone. Call (419) 731-9193 and we will tell you what we find.
Most commonly asked questions about basement waterproofing services.
FAQ's
Why does my Lima basement take water when my neighbor's stays dry?
Usually one of three things. Grade and downspouts, which is the cheapest to fix. Foundation type, since hollow block behaves completely differently from poured concrete. Or position relative to the water table — five lowhead dams sit inside the Lima city limits, and homes near those impoundments have a locally elevated water table that does not drop much between storms. An on-site inspection tells us which one you are dealing with, and the answer changes the price substantially.
Can you just inject the crack in my basement wall?
On a poured concrete wall, often yes. On a hollow concrete block wall, which describes most Lima basements built after 1940, no. The water in a block wall is not in the crack — it is standing inside the hollow cores of the block. Drill a weep hole at the bottom course and it will pour out. Injection has nothing solid to grip and it seals the face while the wall stays full. The right repair is to drain the cores, repoint the failed joints, and deal with what is putting water against the wall.
Do I need a permit for a sump pump in Lima?
Yes, and it comes from a place most people do not expect. Plumbing permits in this area are issued by Allen County Public Health, not the city building department, and they must be obtained before work starts. Contractors doing plumbing work have to be registered and bonded with the department. A homeowner can pull their own permit, but only if they live at the residence and sign a notarized affidavit saying so. We handle the permit as part of the job.
Can my sump pump discharge into the sewer?
No. Allen County Sanitary Engineering rules prohibit connecting sump pump discharge lines to the building sanitary drain. It confuses a lot of homeowners, because city ordinance separately requires that wastewater be connected to the public sewer — so one rule sends water to the sewer and the other keeps it out. Sewage goes to the sanitary sewer; groundwater does not. We route discharge to daylight or to storm drainage, far enough from the foundation that it does not come straight back.
My basement has been fine for thirty years. Why worry now?
Because that is exactly what happened here in June 2015. Lima took 7.87 inches of rain in one week, including 3.68 inches in a single day, which broke a record set in 1912. The Ottawa River crested at 21.20 feet, the highest on record. A fifty-year-old building on South Collett Street took more than two feet of water and had never flooded before. Four of the five highest crests on record have happened since 2011. A basement that has stayed dry has stayed dry under the conditions it has seen so far.
