Dry Basements Start Here in Blair, NE
What starts here is a request to be contacted, nothing more, and nobody can honestly promise a basement that never takes on water. Blair is the seat of Washington County, about 22 miles north-northwest of Omaha City Hall, a county-seat town in its own right with its own building department and utilities.
This site advertises and refers; it is not a waterproofing company, a plumber or anyone's agent, holds no Nebraska contractor registration, and never visits a house, prices a job or signs a contract. One independent contractor receives your request and may pay this site a flat rate to advertise, currently waived for a trial. You pay nothing, and nothing is paid to you.
Basements Built Before 1960 in Blair, NE
Census survey data put the typical Blair home at about 1965. Roughly a quarter of the 3,285 homes date from 1939 or earlier, about 3% from the 1940s and 17% from the 1950s, so about 45% predate 1960. About 73% are detached houses, owners live in about 73% of homes, and the median value is $221,500. The 2025 Census estimate counts 7,997 residents.
Those houses can stand on poured, block, brick or stone walls. Not every one has a full basement, and newer houses may differ, so this page is for owners whose homes have one.
Platted in 1869 when a rail line reached the site, the town took the name of railroad magnate John Insley Blair, became a city in 1872 and was named county seat within that first year.
What Blair, NE Homeowners Ask For
- Seeping mortar joints. Older brick, block and stone walls can let water through worn mortar, so repointing and an interior drain often go together.
- Egress window wells. A larger basement window, or one the building code calls for, takes a city Miscellaneous Permit, and the well needs to drain.
- A sump that empties outdoors. Pumped water belongs outside, well clear of the foundation and the neighbors; any tie-in to a pipe is for a licensed plumber.
Rain and River Water Around Blair, NE
Blair sits among rolling loess hills above the Missouri River valley. Loess and the clayey glacial till beneath it can hold water against a wall after a long soaking, and that slow push is the seepage waterproofing is meant for. Single storms count too: Blair got 3.8 inches on June 3, 2014 (KIOS).
River water is another matter. Missouri River flooding in June 2024 left about four inches of water in the basement of at least one home north of town, beyond where the flood barrier ends north of the Blair Bridge (WOWT via 1011 Now). No drain or sump holds back a river; waterproofing handles groundwater working through walls and floors.
Blair, NE Permits, Registration and Sewer Service
The Building Department, 218 S 16th St, 402-426-6696, issues permits. Foundation or structural repair may need one, and drain or sewer work its own permit, which a licensed plumber pulls; the contractor checks which apply. Blair also asks contractors for proof of Nebraska Department of Labor registration, a city registration and a liability certificate, so ask to see all three.
Blair runs its own sewer system through its Utilities Department: (402) 426-6698 on weekdays, and the Water Treatment Plant, (402) 426-9661, after hours, on weekends and on holidays. Omaha addresses report backups to Omaha; Blair handles its own. If the trouble is in your own pipe to the street, that is work for a licensed plumber, and the city can say where your share ends.

Local Questions
Do I need a permit to enlarge a basement window in Blair?
Often, yes. Blair requires a Miscellaneous Permit when a replacement window isn't the same size as the old one, or when the building code calls for an egress window. The Building Department can say what applies to your plans, and the written contract should name who pulls the permit.
Water came up through my floor drain on a Sunday. Who do I contact?
That points to the sewer, not seepage, so waterproofing won't solve it. On weekends the Water Treatment Plant, (402) 426-9661, covers Blair's sewer trouble; for anything threatening safety, dial 911. A licensed plumber can say whether a backwater valve makes sense for the house.
Would waterproofing have kept the 2024 river water out?
No. When the Missouri River spreads over low ground, water enters through openings faster than any drain or pump can move it. Waterproofing targets groundwater seeping through walls and floors after heavy rain or a wet spring, not a river that has left its banks.
What paperwork should I ask a contractor for?
The three items Blair requires, plus a written contract with the work, materials, price and finish date, as the Attorney General advises. Check state registration at dol.nebraska.gov or (402) 471-2239. Pay in full only when the job is done; signing at home, you may have three business days to cancel. Complaints: (800) 727-6432.
