  • ProVia
  • Pella
  • Sierra Pacific Windows

Every reason people call us about windows

Built around your home, not a catalog.

Tap any one — here’s what actually changes when the windows are done right.

  • Lower energy bills

    Comfort-Foam R5 fills the frame where cheaper windows leave hollow air, and a metal-free Warm-Edge Super Spacer kills the cold edge. Soft-Lite seals to .08 CFM — about four times tighter than the AAMA standard.

  • A quieter house

    Multi-pane glass and tight seals shut out traffic and mowers. Pella’s triple-pane sound package cuts outside noise up to 52%.

  • No more foggy, sweating glass

    Fog between the panes means a failed seal. The Warm-Edge Super Spacer keeps the glass edge about 16° warmer — seals last longer and winter condensation drops.

  • Easy to live with

    ILTIS dual-action sashes tilt in so you clean both sides from inside. Vinyl and aluminum-clad finishes never need scraping or paint.

  • Locked up tight

    K-Beam meeting-rail reinforcement — Kevlar-cored, stronger than steel — backs the lock. Multipoint hardware standard, laminated glass where you want more.

  • Floors that don’t fade

    Low-E coatings block up to 95–99% of the UV that fades hardwood, rugs, and furniture — without darkening the room.

  • Curb appeal that holds

    Sierra Pacific runs 50 cladding colors over real-wood interiors; Soft-Lite adds woodgrain interiors and Sure-Coat exteriors engineered to keep their color.

  • Backed in writing

    20-year to lifetime manufacturer product warranties, 5-year Excel labor, and no service-fee gate when you call us out. It’s in the contract.

THE EXCEL PROMISE

How we do business.

Three things we hold to on every job — the reasons families call us back and send their neighbors.

  1. Same owner, same crews

    Chris still runs the company he started, and the same installers come back job after job. You're never handing your house to a stranger.

  2. Education over selling

    We walk you through the options and leave a written proposal — not a high-pressure pitch. You decide on your own time.

  3. The care we'd want at home

    Most of our work is repeat and referral — because every job gets the same care and craftsmanship we'd want in our own homes.


WHAT TO EXPECT

  1. 01 Call or form
  2. 02 Schedule visit
  3. 03 Design appointment
  4. 04 Final measure
  5. 05 Install (average 1–2 days)

Most projects run about 6–8 weeks from first call to install day.

Backed For The Long Haul

The warranty isn’t fine print. It’s the whole point.

A window is only as good as what stands behind it. Here’s exactly what you get — written into your contract, not promised at the door.

  • 20yr–Life

    Manufacturer product warranty

    From 20-year glass coverage to fully transferable lifetime, depending on the line. Soft-Lite and ProVia carry lifetime; Sierra Pacific runs 30/20.

  • 5 yr

    Excel labor warranty

    On every window we install. If our workmanship is the issue, we make it right — no argument about whose fault it is.

  • $0

    No service-fee gate

    Call us out under warranty and there’s no per-visit charge just to ask. A lot of companies bury that fee. We don’t have one.

Financing available — ask about options at your free consultation.

IN THEIR WORDS

What our windows customers say.

The Windy City Chicagoland
★★★★★
“Great experience with my new front door system installation as part of our Chicago Bungalow restoration project. Installers Dave and Steve Jr. started right on time and did their expert install. Real craftsman! They were able to preserve my original 1928 inside trim, which is no small feat, but that's where experience pays off. Cleaned up well and hauled away the old system. Excel did our whole house of windows in 2007, and the windows still look and operate like new. We are very happy we used Excel once again (prices are competitive and very fair) and we always highly recommend them.”

“From the beginning, Excel windows made our decision easy to choose them for our new windows. Their price was very reasonable. Aside from great price, their customer service is on another level. They really go above and beyond to make sure the customer is satisfied. Matt was our salesman and he was very knowledgeable an d patient with us. He answered any questions I had regarding the windows. Leo is very professional and friendly. He really helps everything run smoothly and makes the transition easy. The installers were professional and punctual. They finished 27 windows in one day in a timely manner. We were in the middle of a home renovation and ordered 9 more windows from Excel because of how beautiful everything turned out. I will never go to any other place for windows. I've already recommended them to a couple of family members and a friend. We are very happy with our experience. Thank you Excel for such a positive and stress free experience from start to finish!”

“We had an amazing experience with Excel. We recently replaced 5 windows in our house. We got four quotes and they were equal to the lowest quote but had a superior product. Last week we had Juan T and Salvador come to install the windows and I cannot say enough about how happy we are with them. They were professional and went above and beyond. When installing the windows a little bit of paint around the window frame got taken off. They even asked for paint to repaint that area before leaving. They vacuumed and left our house looking better than it did before they came. The windows are beautiful and they way they install them looks amazing. They noticed a tiny rip in the screen and informed me of it and already ordered the replacement even before showing me. It's so small I never would have even noticed. They really take pride in their work and it shows. We will be using them for every window and door we replace in our home and would recommend them to anyone.”

“Extremely happy with Excel. It started with a young neighborhood canvasser named Vinnie who did a great job peaking my interest on replacing my front windows. From there, I was contacted by a salesman Matt Reed who came out and took his time describing and demonstrating all the different options and cost structures. I was very impressed with his knowledge and he absolutely did not try and oversell me. After the contract was signed and deposit made, I communicated mostly with Leo in the office who did a great job of keeping me posted on the progress and scheduling install appointments. Juan and his install screw were great. They installed 10 total windows in deep snow and cold temps and got it all done in one day. I cannot say enough good things about Excel, and will refer them to friends and family and absolutely use them again.”

“Excellent sales person (Dominick) explained everything, answered all questions, and started the process. Measurements were done perfectly, scheduling was very efficient and communication was great. Windows arrived as planned, the installers were great, cleaned up after, as if they were never there. Very happy with the new windows, had 19 replaced front and back of the house, look great, inside and out. No issues, No complaints, pricing was extremly competitive, would highly recommend Excel for your nest home project. I will call them in spring when I need to replace my patio doors.”

“We were referred to Excel and were very pleased with our experience. We appreciated the straightforward sales approach, the time we were allowed to consider and make a decision, and the flexibility in scheduling to best fit the needs of our household. The installation team was prompt and efficient. When they left at the end of day 1, they were very thorough in cleaning up behind themselves. When an unforeseen issue caused a delay in them being able to return the next day, Leo made sure communicate with us quickly about the issue and reschedule. On top of all that - the windows look beautiful! We would definitely recommend Excel!”

“Just had my windows installed 2 days ago. Although it's too early to comment on the product, I can confidently say dealing with this company is a refreshing change from dealing with many other companies where customer service is not a priority. Tony, our salesman was great. Very friendly and thorough. Franz, and other employees I spoke with on the phone leading up to installation ALL exhibited genuine care and were pleasant to talk to. My installers were amazing. They were very friendly. They cleaned up everything and addressed any concerns. I don't recall their names, but it was a father and son team. They had a great work ethic. Assuming the windows are going to be as great as the service, I highly recommend Excel.”

“Excel windows has been a great experience to work with. I purchased windows last year for the upstairs of my home and the pricing was good the installation team was great. I'm now getting ready to complete the rest of my home they came out quickly to measure and provide a quote. Kelly in the office followed up the next day to make sure everything went well and asked if I had any questions or needed any additional information. Highly recommend Excel Windows.”

Windows — common questions

How long does a window job take?

Most whole-home jobs run one to two days. We give you a real timeline at the consultation, not a guess.

Will the same crew be on my whole job?

Yes. We send the same crews job after job — low turnover, same faces from day one to handoff. We're not picking a name out of a hat and sending a stranger to your house.

What brands do you install?

Soft-Lite is our primary line (Elements and Classic Plus), plus ProVia, Sierra Pacific, and Pella — depending on what fits your home and budget.

What actually makes a window energy-efficient?

Three things working together: a Low-E glass coating, argon gas sealed between the panes, and a warm-edge spacer that stops heat escaping at the glass edge. We also foam-fill the frame (Comfort-Foam R5 on Soft-Lite) where cheaper windows leave hollow air.

What's "air infiltration," and why does .08 CFM matter?

Air infiltration is how much air leaks straight through the window. The industry standard (AAMA) allows .30 CFM; our Soft-Lite line tests at .08 — roughly four times tighter. Less leak means lower bills and fewer drafts.

How low do the U-factors go?

As low as 0.17 on ProVia Endure. U-factor measures heat loss — the lower the number, the better the window holds your heat in winter and out in summer. We'll show you the rating on the exact glass package you're considering.

What warranty comes with the windows?

Manufacturer product warranties run 20-year to lifetime depending on the line, plus 5-year Excel labor on every window we install. No service-fee gate when you call us out under warranty. The specifics are written into your contract.

Are your windows Energy Star?

Some — it depends on the glass package you choose. Energy Star isn't a blanket claim across every window. We'll tell you which configurations qualify before you sign.
