Why It Works
Double and triple-pane windows with low-E coatings block cold air infiltration that drives up heating bills.
Qualifying window replacements are eligible for ComEd rebates. SPM handles the paperwork from start to finish.
Modern multi-lock window systems are significantly harder to force open than older single-lock designs.
Triple-pane windows reduce outdoor noise by up to 50%, making them ideal for homes near roads, railways, or airports.
The SPM Approach
Windows are where the SPM energy plan starts. Replacing drafty or single-pane windows reduces your home's heating and cooling load, so any solar system we add later can be smaller, cheaper, and faster to pay off. Efficiency before generation is how we build plans that actually work.

We measure every window opening and evaluate your current windows for energy loss, condition, and style fit.
We help you choose the right window style, glass package, and frame material for your home and Illinois climate.
Windows are made to measure for your openings. Standard lead time is 3–5 weeks from order.
Our crew installs and seals every window to manufacturer spec. Old windows and debris are removed and disposed of.
