Insulation Built for Dublin's Elevation and Wind
We install spray foam and cellulose insulation for homeowners in Dublin NH and the surrounding Monadnock Region.
What Dublin's Elevation Homes Actually Need
We offer two core insulation services: spray foam for basements and crawl spaces, where it seals out moisture and drafts, and cellulose for attics, where it's blown in for complete coverage. We match each project to what your home actually needs.
Spray Foam Insulation
Basements and crawl spaces benefit from spray foam's airtight, moisture-resistant seal and high R-value per inch, installed with a clean finish.
Cellulose Insulation
In attics, we recommend cellulose. Made from recycled materials, it's blown in to fill cavities and cover the attic floor completely.

Frequently Asked Questions
Is spray foam necessary in Dublin NH, or does cellulose cover it on its own?
It depends on where the home is losing heat. Cellulose handles attics well, but spray foam is better suited to basements and crawl spaces where air sealing matters more. Many homes need both.
How much insulation do homes at Dublin's elevation typically need?
R-15 or higher on basement walls and R-49 to R-60 in the attic is what Energy Star recommends. We'll take a look at your home's current insulation during your free quote visit.
Will spray foam installation at Dublin's elevation require me to leave the house?
It depends on which areas are being treated and the product used. We ventilate the workspace during and after the job and explain exactly what to expect during your free quote visit.
Will insulating my home lower what I spend on heating and cooling?
It depends on your current insulation and where the heat loss is happening. Sealing those specific areas tends to make your home noticeably more comfortable. We'll look for that during your free quote visit.
