Why homeowners pick Greenify for wall insulation
Warmer, more even rooms
Insulated walls slow heat loss, so the room over the garage and that cold back bedroom feel closer to the rest of the house.
Lower utility bills
Less heat escaping means your furnace and air conditioner run less. That is the whole reason we started this company in 2012.
Work with what you have
Drill and fill adds insulation to wall cavities that are already closed up, so you do not have to gut your walls to fix them.
One team for the whole home
Walls, attic, crawlspace, air sealing, duct sealing, windows and solar all come from the same local company.
We check before we sell
A home energy assessment shows where your house is losing energy, so you only pay for upgrades that make a real difference.
Northern Utah local
We install for homeowners across the Salt Lake City region and surrounding northern Utah communities.
What exterior wall insulation work looks like
Most older Utah homes were built with little or no insulation inside the exterior walls. You feel it as cold walls in winter, warm walls in summer, and a furnace that never seems to catch up. Drill and fill is a way to insulate those closed wall cavities from the outside or inside, instead of tearing out finished walls.
Walls are only part of the story. We look at the attic, the crawlspace and the air leaks around the house too, then tell you which upgrade gives you the most comfort and savings for your budget.
- Attic, wall and crawlspace insulation installation and upgrades
- Air sealing around windows, exterior doors and trim, plumbing penetrations and electrical outlets
- Home energy audit using a door fan and a thermal camera to pinpoint leaks and drafts
- Attic radiant barrier to reflect summer heat away from the home
- Aeroseal duct sealing that seals HVAC duct leaks from the inside out
- Low-E replacement windows to cut heat transfer and block UV
- Solar attic fans to lower attic temperatures without adding to your power bill
- Residential solar, battery storage and Level 2 EV charger installation when you are ready for the next step

Frequently asked questions
What is drill and fill insulation?
It is a way to insulate exterior walls that are already closed up. Insulation goes into the wall cavity through small access points, so you avoid opening the finished wall. We confirm the right method for your home during the assessment.
How much does exterior wall insulation cost?
Price depends on the size of your home, how many wall cavities need filling, the siding or wall surface and whether you add attic or crawlspace work. We give you a quote after we look at the house.
Do you serve my area?
We work with homeowners in Northern Utah, including the Salt Lake City region and surrounding northern Utah communities. We do not work outside Utah.
Should I insulate my walls or my attic first?
That depends on your home. A home energy audit shows where you are losing the most energy. Many homes get the biggest gain from attic insulation and air sealing, but cold exterior walls can be the main problem in older houses. We tell you what we find.
Do you do new construction or roof work?
No. We work on existing homes. We do not do new home construction, general remodeling, roof replacement or furnace and AC replacement.
Can you handle other energy upgrades at the same time?
Yes. Along with insulation we offer air sealing, Aeroseal duct sealing, radiant barriers, Low-E replacement windows, window tinting, solar attic fans, tankless water heaters, solar, battery backup and EV chargers.
