Window Replacement FAQs

window replacement FAQs

We know that the idea of replacing your windows or doors often leads to a number of questions. Here are our window replacement FAQs and some answers to help you get started.


Do you have your own window installers?

Yes, we do! While many in the industry hire subcontractors to install windows, we have our own dedicated, in-house team of installers. This is important to us—and to you—because when you hire McCann, you know what you’re going to get. We offer a greater sense of accountability because our installers are part of our company.

Do you have a showroom?

We have showroom items and various displays of windows and doors at our facility, located at 3375 Commercial Ave. in Northbrook. If you’d like to stop by, our hours are Monday–Thursday, 8-5; Friday 8–3; Saturday– Consultations by appointment. However, we typically bring samples to you, right in your own home. We make the process as time efficient and convenient as possible.

Why should I buy Pella windows from you instead of going directly to Pella?

We understand that many consumers prefer to have a big name behind their purchase, such as a big box store. McCann is here for those looking for a name-brand manufacturer like Pella, easy access, and a little more personal attention. You’ll work with a company you have easy access to, and you won’t get lost in the maze. Plus, we offer competitive pricing and zero percent financing through GREENSKY. Not to mention, your windows will be installed by our dedicated in-house team of window professionals. If you were to work with Pella directly, you’d have one of 40 different installer teams coming to your house.

Why should I buy windows from you instead of a big box store?

For the same reasons we recommend clients buy from us instead of Pella directly: we offer peace of mind by selling windows from several name brand manufacturers; we are a local, family-owned company; we’re easier to reach and offer more personal attention than a big box store. If you have questions or concerns, you can call us and we’ll pick up the phone. You avoid falling into an impersonal, automated phone system to try to reach someone who can answer your questions.

What type of windows should I buy: vinyl or wood?

It depends on the situation. Both vinyl and wood are energy efficient, easy to clean and look nice. Both also will be more secure and reduce sound compared to older windows. Neither wood nor vinyl windows need to be painted. The key difference is longevity and whether you have the desire and budget to invest in a premium, higher-priced wood product. HERE’S ADDITIONAL INFORMATION ON WOOD OR VINYL.

If I buy Pella or Marvin windows and have a problem with them 5 or 10 years from now, who do I call?

Your satisfaction is our top priority. If you have an issue, call us, whether it has been 5 years, 10 years, or even longer. While you can call the window manufacturer, please let us do the legwork for you!

Will I lose daylight when I replace my windows?

We generally install new windows by replacing both the window and the frame. When we do this, you will not lose any daylight. On rare occasions, we set the new window inside the existing frame. Technically, this reduces the amount of daylight coming through the window, but it’s so minimal that you won’t notice the difference.

Is it true that vinyl windows “fall apart”?

This is simply not true. What’s most important when choosing a vinyl window is the window manufacturer—the quality, longevity, and reliability of the company. Premium window makers, such as Pella and Marvin, take more time and put more effort into their designs. They also use more expensive and more durable parts. Premium manufacturers take more time to manufacture their quality windows. This also means they command more in price. We want to help you choose the product that’s best for you. McCann will explain the pros of different window materials and makers.

Do wood windows need to be painted or stained?

No, they don’t. All of our windows come with permanently finished cladding on the outside, and the interior is pre-stained or pre-painted. There’s no extra work for you!

What is the U-factor?

It’s a measurement of the energy efficiency of a window. Like golf, the lower the score, the better. We’ve seen as low as 0.19, although windows with that rating are more appropriate for the Arctic Circle than Chicago. When McCann advises our clients, we follow the Energy Star program guidelines and only use products appropriate for our climate. (But if you’re interested, we can get windows with a U-factor of 0.19.)

We serve homeowners in the Chicago northern and north shore suburbs and the surrounding towns and villages.

 I am very happy with the new windows McCann installed for us. They were able to install them quickly and did a very thorough job. Mark and Angel did a great job! I would highly recommend McCann to anyone looking to replace their windows. Thank you McCann! 
 I can only say good things about the people I dealt with with McCann, from Kevin, and Jim, and all the installers. They did a great job, their customer service was excellent, they were very clean, and I am as happy as can be. They were professional, and a pleasure to do business with. 
 Just nice people all around. They know their stuff, have several quality options to choose from (less to more expensive), & didn’t pressure sell. Easy install, quality workmanship. Super satisfied with our experience.
