A City Built by Annexing Its Neighbors
Spray Foam Insulation in Lincoln starts with knowing which Lincoln you live in. The capital began in 1856 as the village of Lancaster on the east bank of Salt Creek, was renamed and made the capital in 1869, and then grew by absorbing whole towns: Bethany Heights in 1922, University Place in 1926, College View in 1929, Havelock in 1930 and West Lincoln in 1966. Each of those places brought its own streets of older houses, and the 2020 census counted 122,048 housing units across the city.
Old neighborhoods, hollow walls
In the older parts of town, the usual story is plaster walls with nothing behind them, balloon framing that lets air run from the basement to the attic, and an attic floor with a few inches of settled insulation. Those homes benefit most from dense-pack wall insulation and attic air sealing. This is also the housing LES had in mind with its 2026 sealing and insulation incentive, which is limited to existing homes with no wall insulation or attic insulation at R-19 or less.
Mid-century ranches and split-levels
The ranches built after the war usually have some attic insulation, but rarely enough, and their rim joists are often bare. A split-level adds a tricky spot where the upper level hangs over the lower one. Closed-cell foam on the rim and the cantilevered floor, plus air sealing and blown-in over the ceiling, is a typical plan.
Newer subdivisions
Houses built under Nebraska's statewide 2018 energy code, in force since July 1, 2020, were designed for R-49 ceilings and a blower door result of 3 air changes per hour or less. The comfort complaints we hear in newer Lincoln homes usually come from one room: a bonus room over the garage or a finished basement that never feels like the rest of the house.
Weather from both directions
Lincoln's 1991-2020 normals show a 14.4F average January low and a 78.1F average July day, with records of -33F and 115F. The city article also notes an EF2 tornado in 2019, an EF3 in 2024, and increasingly common hail and wind. After a roof repair, check the attic for wet insulation before winter.

Lincoln Questions
Does my Lincoln house qualify for the LES insulation incentive?
LES lists it for existing, occupied homes in its service territory that have no wall insulation or attic insulation at R-19 or less. The project needs pre-authorization before work starts and blower door tests before and after. Funds run January 1 through December 31, 2026, first come, first served.
My older Lincoln house has plaster walls. Can they be insulated?
Yes. Dense-pack cellulose or injection foam goes in through small holes, often from the outside behind the siding. We check the wiring and confirm the bays are empty first.
Why is my bonus room so hot in the summer?
Bonus rooms have a floor over an unheated garage, short kneewalls and a sloped ceiling close to the roof. Those spaces are often under-insulated and leaky. Foam on the kneewalls and floor, and sealing at the ceiling, usually fixes it.
