They did such a good job on my windows I’m…
This company by far goes above and beyond more than any other contracting firm I’ve done business with. I’m renovating my family home that has not seen major repair work since 2001 when it was built. Just had the windows redone and Anthony walked me through the whole renovation and corrected all the flaws I was not happy with. On top of that they installed 25 non standard sized windows/ 6 ft sliding door and 3 architectural windows in a span of less than 8 hours. The crew were clean, respectful of the home and efficient. I also like the fact that they stand by their installation with a 50 year warranty. And the best part: I didn’t have to pay for anything till I was fully satisfied with the install!!! I can’t say enough good things about them. Definitely recommend. They did such a good job on my windows I’m having them do my roof as well.
I will definitely be contacting them if I have any…
As a first time homeowner/ widow having a trustworthy company that won’t lie just so they can get money from you when all I needed was a patch repair for a hole I had in my roof. I appreciate Willie, he made sure I was in the emergency list to get it fixed ASAP. Even though I had to pay a little bit more than the other companies I decided to go with Apex for their honesty and to me that is worth a lot more. I will definitely be contacting them if I have any other roof issues.
I will be returning to them when it makes sense…
Apex was fantastic to work with. They came out quickly to assess my roof and walk me through my options. Despite a new roof installation being in their best interest, they were willing to install a temporary tarp right away to prevent further damage while we weighed the best solution long-term. I will be returning to them when it makes sense to install a new roof.
Common Questions About Apex Exteriors’
Window And Doors In LaGrange, Illinois
Clear Information About Window
And Door Replacement
Planning new windows or doors for your Cook County, IL home raises questions about cost, materials, and how the work will impact your day-to-day life. These FAQs cover the basics we walk through during an in-home consultation so you can feel prepared and informed.
Am I Within Your Service Area?
Our company is based in South Elgin, Illinois, but we install replacement windows throughout the Chicagoland region. Our red work trucks can be seen from St. Charles to Naperville, Hinsdale to Arlington Heights, and Evanston to South Wisconsin’s Lake Geneva. Visit our Service Areas page for more information, or call us if you’re unsure.
Can I Finance My Window Project With Apex?
Financing window replacement is common, especially when replacing a large number. Other customers finance to get higher-quality or longer-lasting windows. At other times, they finance because windows are just one part of a much broader project scope. In any case, we can help. Visit our Financing page for more info, or call and let us know you’re interested.
How Long Will My Window Replacement Project Take?
This all depends on your situation. For example, installing 20+ windows takes our in-house teams longer than 5-10 windows. Are these somewhat conventional windows, or highly customized and being installed in harder-to-reach places? Your timeline will be clearly outlined at the beginning and throughout every step of your project. You’ll always know who’s doing what, when, and for how long.
Is Replacing Windows With Apex On The High-End?
It can be. We can install the most expensive luxury windows on the market or more affordable premium brands like Pella. That said, it really comes down to the type of windows you want, the number we’re installing, and what’s involved.
