Energy Efficiency

This post is basically my Notes app, cleaned up just enough that it’s readable.

Because the real file looks like:

“attic guy #1: $2,950 (fast)”

“attic guy #2: $6,480 (air seal?? baffles??)”

“attic guy #3: $14,600 (spray foam voice. very confident)”

And then: “why are these numbers not even in the same universe.”

Also, small confession: I didn’t grow up thinking about R-values.

I grew up thinking about “why is the upstairs always 8 degrees hotter” and “why does the hallway smell like attic dust when the furnace turns on.”

Window replacement is one of those projects where the first quote makes you go:

“Wait. For windows?”

And then the second quote makes you go:

“Wait. For the same windows??”

Because a “window quote” is rarely just a window. It’s a bundle of decisions and risks:

• Are we doing a quick insert/pocket swap, or tearing back to the rough opening?
• Is the exterior easy (vinyl siding) or annoying (brick/stucco/old trim that disintegrates when you look at it)?
• Are we finishing it like adults (trim/paint/capping) or leaving you with a follow-up project?
• Are we quietly dealing with code stuff (tempered/egress) and older-home stuff (lead-safe practices)?

If you’re stacking projects this year, the same “force scope or the numbers are fake” rule applies to other stuff too: attic insulation cost in 2026 and garage door replacement cost in 2026.
