Windows & Doors › Energy Efficiency
Stop paying to heat the sky.
Where the losses actually are in a southeastern PA home — and which fixes are worth the money.
What's included
Where homes lose energy
- Air leaks at rim joists, penetrations, and attic hatches
- Under-insulated attic floors — still the best dollar-per-return fix
- Single-pane or failed double-pane glazing
- Unbalanced attic ventilation causing heat and moisture buildup
- Uninsulated rough openings around windows and doors
- Gaps at the sill plate behind old siding
Worth knowing
Upgrades ranked by return
- Attic air sealing and insulation — fastest payback, lowest cost
- Balanced soffit-to-ridge ventilation
- Low-E argon glazing on the sun-exposed elevations first
- Air sealing rough openings during any siding or window job
- Full window replacement — real comfort gain, longer payback
Straight talk
What to expect
Replacing windows is rarely the cheapest way to cut an energy bill, and we would rather tell you that than sell you twelve units. Attic sealing and insulation usually wins on payback. Windows win on comfort, drafts, noise, and how the house feels to live in — which is a legitimate reason to buy them.
