How to choose a window company in Chicagoland

You’re going to get three estimates, and they’re going to sound almost identical. Same lifetime warranty. Same efficiency pitch. Prices that swing by thousands for reasons nobody explains.

The differences between companies are real. They just don’t show up in the brochure. They show up in seven questions, and most homeowners don’t know to ask them.

Here they are. Ask all seven, of everyone. Us included.

1. Who is actually installing my windows?

Ask: “Are the crews doing my install the same ones you’ve worked with for years, or brought on for the season?”

Installation is where most window jobs go wrong. A well-built window set into an out-of-square opening, shimmed wrong or sealed badly, will leak air and eventually water. The manufacturer’s warranty won’t cover any of it, because the window didn’t fail. The install did.

Crews that turn over every spring never build that judgment. Ask how long the crews have been with the company. It’s a fair question, and the answer tells you plenty.

Our answer: the same crews, job after job. Ask us how long. Then ask the other two the same thing.

2. What does the warranty cover, and what does a service call cost?

Ask: “If a sash fails in year seven, what do I pay?”

“Lifetime warranty” means almost nothing by itself. What matters is the gap between the part and the visit. Plenty of companies will ship you a free replacement sash and charge you a trip fee to install it. Some warranties are also non-transferable, which quietly matters if you sell.

Get it in writing from everyone. Ask four things: is labor covered, is there a service fee, does the warranty survive if I sell the house — and who registers the product. That last one catches people out. Some manufacturers require the windows to be registered within 60 days of installation for the warranty to be active at all. Miss it and you have no coverage, and nobody finds out until years later, when they need the repair.

Our answer: labor is covered for five years. If the repair is under warranty, you are not paying us to show up — there’s no service-call fee to come out during that period. A service call costs you something only once you are outside the warranty.

On transferring it, be careful with any company that says “fully transferable,” and that includes checking us. Our primary line, Soft-Lite, carries a lifetime product warranty that lasts as long as you own the home, with a one-time transfer to the next owner — not unlimited, once. It does pass to your buyer, and it’s worth putting on the listing. Ask us for the current transfer terms in writing, ask the other two for theirs, and compare the actual mechanics rather than the word “lifetime.”

3. Are the windows made to my openings, or pulled off a shelf?

Ask: “Is this made to order, and what’s the lead time?”

Stock windows come in fixed sizes. When your opening doesn’t match one, the installer makes up the difference with trim and filler, and that’s exactly where drafts start. Made-to-order windows get built to your opening’s measurements.

The trade-off is honest: made to order takes weeks. Anyone promising you a custom window by next Tuesday is selling you stock.

Our answer: built to your openings. That’s why there’s a lead time, and we’ll give you a real one instead of a hopeful one.

4. Is the quote itemized, in writing, and good for how long?

Ask: “Can I have that in writing, broken out, before I decide?”

A number written on the back of a brochure isn’t a quote. You want the window line, the labor line, disposal, permits where they apply, and the warranty terms. On paper. With a date.

Be careful with a price that expires tonight. A discount that’s only real if you sign before the salesperson reaches their car is a pressure tactic wearing a discount’s clothes.

Our answer: written, itemized, and it doesn’t evaporate when we leave. Take the week. Get the other two quotes.

5. Can I verify your credentials and coverage myself?

Ask: “What are you licensed for, and can I see a current certificate of coverage?”

Here is the part most companies will not volunteer: Illinois does not license window contractors. There is no state window-installer credential to hold. So when a company calls itself “state licensed” on a window job, the honest follow-up is: licensed for what?

What you can actually verify is a current certificate of coverage — general liability and workers’ comp both — and whether the company is registered with your village, since plenty of Chicagoland municipalities require that on top of anything from the state.

Our answer: ask us for the certificate and we’ll hand it over. We’ll also tell you straight that there is no state window-installer credential for anyone to hold, ours included — so if another company implies it has one, they’re counting on you not knowing that. Verify the coverage, verify the village registration, and judge the rest on the other six questions.

6. Who do I call in year three?

Ask: “If something’s wrong two years from now, who picks up the phone?”

This is the one that separates a local company from a sales operation. Ask whether service runs through the same office that sold you the job or a national warranty line. Ask what happens if the company changes hands.

Our answer: the same Tinley Park office you bought from. We’ve been doing this since 1982, family-owned the whole way, and we run about 1,166 projects a year. There’s no call center in the middle.

7. How is the financing being presented?

Ask: “What’s the APR, and what’s the cash price?”

Monthly-payment selling hides the total. A comfortable payment stretched long enough can cost far more than the job is worth. Ask for both numbers and compare those, never the monthly.

Our answer: financing is available, subject to credit approval, and APR varies. Ask us for the cash price and the financed total side by side. Any company worth hiring will hand you both.

The short version

Ask all seven:

1. Who’s installing, and how long have those crews been with you?
2. Is labor covered, is there a service fee, and who registers the product?
3. Made to order or stock, and what’s the real lead time?
4. Itemized, in writing, good for how long?
5. What are you licensed for, and can I see a current certificate of coverage?
6. Who answers in year three?
7. What’s the APR, and what’s the cash price?

We’d rather you ask all seven of three companies than take our word for any of it.

When you’re ready to put us through it, the replacement windows we install are Soft-Lite, ProVia, Sierra Pacific and Pella, and the consultation is free and happens at your kitchen table. Family-owned in Tinley Park since 1982.
