Insulating Homes in Plano
Spray Foam Insulation in Plano is mostly about updating older houses. Plano went from 17,872 residents in 1970 to 72,331 in 1980, 128,713 in 1990 and 285,494 in 2020, so a large share of its homes date from the 1970s, 1980s and 1990s. The city is surrounded by other municipalities and has little undeveloped land, which means most housing work here is remodeling, not new building.
Older attics, lower targets
Homes built in the 1970s and 1980s were insulated to the standards of their day, well below what the code calls for now. Many Plano attics we see have a few inches of old fiberglass or settled cellulose, original ductwork and gaps around every wire and pipe. ENERGY STAR recommends topping up to R-38 where three to four inches are already down in Zone 3. Sealing the ceiling first makes that top-up worth much more.
Remodels open the walls
Because Plano is built out, a lot of homeowners remodel instead of moving. When kitchens, baths or whole floors get opened to the studs, it is the one chance to spray foam in the walls. Open-cell fills the cavity and seals around outlets and plumbing; closed-cell gets more R-value into a 2x4 wall. We schedule around the remodel contractor.
Weather extremes
Plano is humid subtropical, with a recorded high of 118F in 1936 and a recorded low of -7F in 1930. Its flat terrain gave the city its name, Spanish for flat. Flat lots and slab foundations are typical, so most of our work is in attics and walls rather than crawl spaces.

Plano Questions
Is my 1980s Plano attic under-insulated?
Very likely by today's standards. We measure and price a sealed top-up.
We are remodeling. Should we spray foam the walls?
If the walls are open to the studs, it is the best time. We can coordinate with your remodeler.
Do you also do blown-in?
Yes. For most Plano attics, sealing plus blown-in is the best value.
