Seal the leaks first. Then the insulation works.
Here’s the piece of the puzzle most estimates miss: insulation without air sealing is a band-aid over a hole. Air leaks around wiring, pipes, ducts and window rough openings will push right through the insulation and carry warm (or cold) air out with it. Sealing those leaks is usually the first thing we do — and sometimes it’s the whole job.
What this means for your home
Here’s the piece of the puzzle most estimates miss: insulation without air sealing is a band-aid over a hole.

Sealing those leaks is usually the first thing we do — and sometimes it’s the whole job.
- We find the leaks with blower-door logic, not just a handheld meter
- Seal the big leaks first: rim joists, wire and pipe penetrations, ducts, window rough openings
- Caulk, foam, and weatherstripping, chosen for the specific leak type
- Often the highest-ROI step in a whole-home energy upgrade, before any insulation
- Can be scoped as a standalone job or bundled with an insulation install
Why TCS
“Insulation only works if it’s installed for the way your house actually holds air.”
We look at air leaks first, moisture second, and insulation depth third. That’s why a TCS install stays comfortable and energy-efficient.
Homes with drafts you can feel
Cold spots near the ceiling, a door that’s always a little drafty, a room that’s always a few degrees off.
Pre-insulation work
If you’re planning an insulation job, air sealing first makes it work better.
Duct and wiring problems
Unsealed ducts and a jumble of wiring in an unfinished space are the classic leak sources.
How we work
The TCS process, start to finish
We find where the air is actually going
We do a quick blower-style test and a visual pass to find the biggest leaks. It’s usually where you’d expect — the rim joist, the wiring, the ducts — but sometimes it’s somewhere you haven’t thought to look.
We rank the leaks by size
Not all leaks are worth the same effort. We prioritize the big ones (the ones that move the most air) first, so the money goes to the right places.
We seal each one with the right material
Caulk for tight gaps, foam for structural gaps, weatherstripping for doors and windows. The material matters as much as the location.
We re-check and document
After the install we do a quick re-check to make sure the seal actually holds. You get a list of what we sealed, where, and with what.
Good to know
Questions people ask before booking
Usually yes, and it’s often the highest-ROI step before you spend on insulation. A home with major leaks will let the warm air out (or cold air in) faster than the insulation can keep it in. Sealing those leaks first is why an insulation job feels better when the leaks are handled.
It helps, it’s not the main problem. Doors are a small leak compared to an unsealed rim joist or a duct that’s got a hole in it. Fix the door (weatherstripping is cheap and easy), but the bigger leaks are usually in the walls, the attic, and around the ducts.
An audit is a good idea for a full-home plan, but for air sealing specifically we do our own leak mapping as part of the quote. You don’t need a third-party audit to fix a drafty house.
Depends on how many leaks and where they are. Some homes are a half-day job (one or two main leaks, easy access). Others with ducts, rim joists and an unfinished attics are a couple of days. The quote will tell you.
