Lee's Summit's 1980s and 1990s two-story homes with walkout basements and bonus rooms over garages sit on rolling terrain where temperature control is a constant battle. A room that never reaches comfort, a cooling bill that climbs into the hundreds by July, or condensation on the rim joist in spring: these are the calls we get from 64063.
Your home was built in an era when attic insulation was often minimal and rim joists were left uninsulated. The bluffs and valleys around Lee's Summit mean attics bake at 130 to 150 degrees Fahrenheit in summer and freeze in January, and bonus rooms over garages or at the end of duct runs are notorious for staying too hot or too cold. Kansas City Spray Foam Insulation has been serving Lee's Summit and the surrounding areas since 2012. We know this building stock, the moisture challenges it faces, and the spray foam and air sealing work that fixes them.
Spray Foam Insulation in Lee's Summit (64063)
Lee's Summit's two-story homes with finished bonus rooms and walkout basements present a specific insulation challenge: the attic above those bonus rooms is often poorly insulated, and the rim joist where the first-floor wall meets the basement rim band is almost never sealed. In summer, heat pours down through the attic into the second story. In winter, cold radiates inward from the rim joist, and humid air infiltrates through gaps in the band board, causing condensation on rim joists and band joists, damp insulation in crawl spaces, and moisture staining on basement walls. The mixed-humid climate means vapor drive flips with the seasons, outward through cold winters and inward through hot, humid summers.
Closed-cell spray foam solves this problem because it is both an insulator and an air barrier. It seals the rim joist completely, stops air leakage into the attic, and resists moisture. Open-cell foam works well in attics where vapor can escape outward through the roof deck and where closed-cell cost is not justified for a top-up of sound existing insulation. We assess your home on site, specify the R-value and thickness you need, and recommend the right foam for your use and budget.
Our team has been insulating homes across Kansas City and the surrounding areas for over a decade. We know the building codes that apply in Lee's Summit, the moisture patterns in this climate, and how to leave your home clean and your insulation right.

How a Job Works in Lee's Summit
We start with a free on-site assessment. You walk us through the problem: a room that will not heat or cool, a high utility bill, visible condensation or damp insulation, or insulation that has failed and needs to come out. We measure the space, look at what is already there, check for moisture or leaks, and ask about your comfort goals and budget. We give you a written estimate that specifies the R-value, the foam thickness in inches, the area to be sprayed, and the cost. No surprises.
On the day of the work, our fully insured crew arrives with equipment and material. If old insulation has to come out first, we remove it and haul it away. We set up mechanical ventilation during the spray, because the smell and off-gassing are real and we manage them. We spray the foam in controlled passes at the correct thickness, at the manufacturer's ratio and drum temperature. The work is noisy and takes a few hours for most jobs. We clean up thoroughly when we are done.
After spraying, we give you a re-entry window of 24 to 48 hours before you occupy the space. During that time, mechanical ventilation runs. After the window closes, the foam is cured and the space is yours. We do a final walkthrough with you, answer any questions, and leave the property clean.
Attic spray foam in Lee's Summit typically runs from $1.50 per square foot for open-cell foam on top of existing insulation, to $1.75 per square foot or more for closed-cell foam in a rim joist or band joist application where air sealing is the goal. Crawl space foam starts at $2,500 and goes up with the square footage and the depth of the space. Wall and injection foam retrofit runs from $2 per square foot. Insulation removal starts at $950, and a full removal and replacement job runs from $2,800 depending on the area and what has to come out. The key cost factors are the area to cover, the R-value and thickness you need, whether you choose open-cell or closed-cell foam, and whether existing insulation has to be removed first. A tight crawl space or a finished attic with limited access adds time and cost. We give you a free written estimate with all the details. Call us at (816) 307-2678 to schedule your assessment.
