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.

Lindsay Windows, the manufacturer that builds our windows
Our other ones got blown out with the bad winds from the tornado. These are much nicer. They have screens, we can open them up, it is a nice addition to the building.
Butch, Bradley Mowers, a commercial building we reglazed after storm damage
The windows have stayed warm on the inside, and in the summer it's been cool. Excellent job, excellent work, craftsmanship, professionalism. They are one top-notch group, and Dave, doesn't get better than him in the business.
Edward Weiser, a homeowner we installed windows and a patio door for
Hey, this is Edward Weiser here with Pippin, and we want to thank Dave and his team for really doing an excellent job on our patio door here and all the windows in my house, the front side of the house and the back side.
Him and his team, they were very professional. They put a lot of time and effort into talking to me, getting what I wanted done in a timely manner. With this guy here, it was important that he's comfortable in the house. The windows have stayed warm on the inside, and in the summer it's been cool.
So Dave and his team, excellent job, excellent work, craftsmanship, professionalism. They are one top-notch group, and Dave, doesn't get better than him in the business. So if you get a chance to work with Dave, do it. His company is reputable, and he goes over and back for his customers. So I'm very appreciative, and so is Pippin. Thanks again, Dave.
The Process
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.
FAQ
ComEd offers rebates for qualifying energy-efficient window installations in Illinois. The exact amount depends on the window type, quantity, and your eligibility. SPM handles the rebate application on your behalf. Typical rebates range from $200-$600 for windows.
ENERGY STAR certified windows can reduce heating and cooling costs by 12-15% on average. In older Illinois homes with single-pane or drafty windows, savings can be significantly higher.
SPM installs double and triple-pane ENERGY STAR certified windows in all standard styles: double-hung, casement, sliding, picture, and bay. We work with leading manufacturers to find the right fit for your home and budget.
Most whole-home window replacements take 1-3 days depending on the number of windows. Individual room replacements can often be done in a single day.
It's worth evaluating first. SPM starts with a whole-home energy assessment before sizing solar, and drafty single-pane windows are one of the biggest sources of heat loss in Illinois homes. Cutting that loss first means a smaller, cheaper solar system can cover the rest of your usage.
SPM installs ENERGY STAR certified windows with a typical 25-year warranty. Well-maintained double and triple-pane windows commonly perform at that level for decades in Illinois climate conditions.
