A Railroad Town on the Farm Road
Spray Foam Insulation in Miles serves a small Runnels County town with a long railroad history. The city is named for Johnathan Miles, who gave $5,000 toward extending a railroad line here. Miles counted 1,302 residents in 1910, fell to 626 by 1960, and had 875 people in the 2020 census.
Older housing
With a population that peaked more than a century ago, many homes in Miles are old. Early frame houses tend to have open wall cavities that connect to the attic, little or no original insulation, and attics that were insulated once and never again. The gaps at the top of interior walls and around chimneys can move a surprising amount of air.
A small, stable stock
The 2020 census counted 364 housing units, 13.2% vacant, with a homeowner vacancy rate of 1.9%. Most homes are lived in, and most are owned by people who plan to stay, which makes long-term improvements like attic sealing worthwhile.
Farm buildings
The census counts the whole city as rural, and steel barns, shops and storage buildings are part of most properties nearby. Closed-cell foam on steel keeps them cooler and stops condensation drip.
Targets
Runnels County is classified as Climate Zone 3B by OpenEI. The 2015 code Texas uses calls for R-38 in ceilings, and ENERGY STAR suggests R-49 for a bare attic.
Farm country around town
Miles sits on the road between San Angelo and Ballinger, and many properties in and around town include a farm shop or storage building along with the house. We can price both on one visit so you can decide where the money goes first.
What a visit looks like
We walk the attic, check the depth and condition of the insulation, and look for gaps at the top plates, chimney, plumbing vents and attic access. If there is a crawl space, we look there too. You get a written quote listing each area, the material we suggest, the R-value it reaches and the price. Nothing starts until you approve it.

Miles Questions
My older house has drafts from the walls. What helps?
Sealing the tops of the walls from the attic and around chimneys and chases often cuts drafts a lot. Closed walls can be dense-packed if they are empty.
Do you work in Runnels County?
Yes, including Miles and Ballinger.
Is it worth insulating a storage barn?
If condensation drips on what is stored inside, foam on the roof usually pays off.
Can you look at the house and the farm shop on one trip?
Yes. We price both on the same visit and list them separately.
