Why Retrofit

Make an older home feel new again

Most homes built before modern energy codes are quietly leaking money through the attic, rim joists, and wall cavities. You feel it as cold floors in January, rooms that never warm up, and a furnace that runs and runs but never quite catches up.

We start by finding the weak spots, then build a practical plan around the house you already have. Usually that means targeted air sealing and added insulation, the upgrades that deliver real, noticeable comfort without tearing your home apart.

What You Get

Comfort you can feel, savings you can measure

Retrofitting is about fixing the right things in the right order, not just piling on more material and hoping.

Even, room-to-room comfort

Bedrooms, additions, and upstairs spaces finally stay consistent through Wisconsin temperature swings.

Lower heating & cooling bills

Sealing leaks keeps the air you paid to heat or cool inside, so your equipment runs less often.

Minimal mess and demo

We work through attics, basements, and rim joists whenever we can, with clean containment and careful access.

Honest, direct pricing

Owner-led scopes with no middleman markup. You only pay for the upgrades that actually earn their keep.

Where We Work

The spots that make the biggest difference

A few key areas are responsible for most of the discomfort in an older home. These are where we focus first.

AtticsAttics

Seal the hidden bypasses and add R-value to stop heat from escaping at the top of the house.

Rim JoistsRim Joists

One of the leakiest areas in most homes, sealed tight with closed-cell foam.

Additions & Bonus RoomsAdditions & Bonus Rooms

Bring older additions and over-garage rooms up to the comfort of the rest of the home.

How It Works

Straightforward from first call to cleanup

Every project runs on the same three priorities: the right material, a clean install window, and direct communication from a local crew.

Install Cleanly

Our crew protects the space, installs the right material, and leaves the area ready to use, not a mess to clean up.

Spray Foam Works did an excellent job in my attic. Aaron was thorough and timely. I would highly recommend them to anyone considering spray foam for insulation.

Questions homeowners ask us

Do you have to open up my walls?

Usually not. Most of the biggest wins happen in attics, basements, crawl spaces, and rim joists. If wall access would genuinely help, we walk you through the options before any work starts.

Is retrofitting worth it before I replace my HVAC?

Very often, yes. Cutting air leakage and heat loss first can make your existing system perform better, and may even change the size of the equipment you actually need.

How disruptive is the work?

Most retrofit jobs are a day or two with careful containment. We protect floors and finishes and keep the work area tidy from start to finish.
