Why I insulate older homes in Cudahy
I started out insulating new houses, back when the walls were open framing and everything was easy to reach. After a few years I moved over to homes people already live in, and I liked that work better, because every attic and crawl space turns out to be its own puzzle. In 2021 I started Landmark Cudahy Spray Foam Insulation here in Cudahy to do that kind of work.
Most of our calls come from people in older houses around Cudahy, with some landlords and small business owners in the mix. They usually call about a room that's hot upstairs, a drafty bedroom or a power bill that keeps climbing. What I care about most is getting the order of the work right, because insulation laid over a problem just hides it. If a job won't help your house, I'll tell you before you spend anything. You can see the work we do on our home page.
We find the cause before we insulate. If it won't help, we'll say so.
How we run a job at your house
I come out to every job, look at the attic or crawl space with you and give the estimate myself. Our installers do the work in the order an older house needs, pulling out soaked or dirty material first, then air sealing the gaps around can lights, pipes and the hatch before any new insulation goes in. I'm on site to check it, and the crew cleans up before we leave.
After I've looked, I walk you through what I found and what's worth doing. If we turn up something outside our work, like old wiring or insulation that looks suspect, we tell you plainly and hold off until it's handled. We check with the building office that covers your address, and when a permit is needed we handle the paperwork and line up the inspection.
