I specialize in repairing existing windows and doors. Where others will quote 1000s for replacement windows, I will quote in 100s and have your windows and doors working as they were designed.

Questions and Answers

  • What we may not know about you?
I am not a traditional "glass guy". While I can, and do, work on any window, I am as much about trying to share my knowledge and expertise as I am about completing any one job. You will get an incredible value for your dollar spent on my services. You will know more about your windows, how to care for them, and how to get the most out of them.
  • What are you most proud of?
Last Fall, I restored the glazing in a 1920's bungalow in Evanston. I removed all of the old hard putty and re-glazed them. This kind of restoration work is what I really hope to, as I hate to see beautiful old single-glazed windows replaced with less-efficient vinyl replacement windows. I will be doing a complete restoration on a 1900's home Summer 2014.
  • How did you get started?
I got my first experience in the glass industry 22 years ago when I worked for a year at a glass tempering plant before going to U of I Champaign-Urbana.A few years after graduating, I returned to the glass industry working for a small family-owned, full-service residential and commercial glazing company. After 13 years there, I formed A Window Guy in 2012.
  • What types of jobs are the most common?
There are four basic types of jobs I do: Replacing broken or failed insulating units. Replacing/repairing broken single-glazed windows. Repairing windows and doors for functionality. And diagnosing/repairing water leaks.
  • How many projects do you average in a year?
I do dozens of jobs per year, and usually 2-3 large projects (window restoration projects). I have recently been solicited to do a very large and extensive restoration on a nearby VA Hospital from the 1800's.
  • How can we save money hiring you?
DO NOT REPLACE YOUR WINDOWS!! Very few windows need to be replaced, and in general, the older they are, the better they are. They can be made to work and seal properly and are almost always "warmer" than replacement windows. Also, vinyl windows are cheap, and you get what you pay for. There are some good ones, but not many, and usually you end up with a "colder" window than you had before. Also, "old" single-glazed windows, used in conjunction with storm windows, are as warm or warmer than ANY window currently available - and they will last MUCH longer than any "new" window on the market.
  • What do you recommend to know before hiring you?
Many people with newer windows do not know what kind of windows they have. Many times the name, or some identifying symbol is printed on the window or door somewhere, or inside of the insulating unit on the metallic spacer-bar between the 2 pieces of glass. Having that information will aid you in your repair needs. Also, understand that materials cost A LOT more than they should. I am putting an end to that practice at A Window Guy.
  • Do you offer any service after finishing the work?
I guarantee my work for 1 year to be free of defects of workmanship. Any and all repairs I make are guaranteed to be sound. The insulating units I use are guaranteed against seal failure for 10 years, and are manufactured by Cardinal IG in Wisconsin.
  • What kind of questions do customers ask you?
The number one question is: "Can you fix my window?" The answer is almost always yes. Some windows are too weathered and/or damaged, or not worth repairing, but most are fixable. The second question is: "Do I need new windows?" Again the answer is almost always "no". Most existing windows are better than most new windows, especially "replacement windows". Period.
  • What is important to know about your profession?
I wish people knew that new windows rarely means better windows. Unless you are going from vinyl windows to wood or clad-wood, or from double-hung windows to casement windows, you are almost always devaluing your home and also usually making it colder/hotter. Also, most glaziers mark up their insulating units and other glass products by 2-3 times, whereas I pass though all materials, without mark up - saving you money.
  • What questions should a customer ask before hiring you?
The most important questions relate to the quality of the job that is to be done. Make sure premium insulating units and materials (caulk, tape, etc) are being used, and always get an idea of what a proper job will look like when it is complete (will painting or staining be required, will the window or door look and function like new, etc).

I had two large sliding door side panel windows that the seals were broken on. Jon did a fabulous job replacing them. He was far less expensive then any other quote I received. I would highly recommend him.
