Who We Are
InsulTech is a family-owned business. We started with a simple idea: do honest, careful work, and treat every home the way we would want our own family's home treated.
What We Do
Our wet winters and damp ground are hard on attics and crawl spaces. We focus on the spaces you rarely see, because they affect the comfort, air, and health of the home you live in every day.
Top up or replace tired attic insulation to keep heat where it belongs and help lower energy bills.

You do not need to know which service you need. Start with what you are noticing, and we will help you figure out the rest.
Uneven temperatures often trace back to thin attic insulation, missing under-floor insulation, or disconnected ducts.
See solutions →When insulation is thin or ducts leak, your system works harder to keep the house comfortable.
See solutions →Moisture under the house can damage insulation and lead to mold. Cleanout and a vapor barrier can work together to help.
See solutions →Mold is usually a sign of excess moisture. We treat the growth and recommend fixes that address the cause.
See solutions →Rodents leave contaminated insulation behind. Sealing entry points and cleaning out the space help restore it.
See solutions →Insulation that has fallen, compressed, or been contaminated does not perform the way it should. Removing and replacing it gives the space a fresh start.
