In 1986 John Gallagher had one goal – to provide top quality exterior remodeling products and workmanship at a reasonable price along with incredible service before and after the job. Exterior Designers Inc started with and maintains that philosophy and mission.

"I requested quotes and met with a number of companies. By far, I enjoyed meeting with John. He was informative and thorough at our meeting. Given the information provided, and our own research, I also felt as though our values matched up nicely. So much so, that we planned on using EDI services, given the quote was reasonable. However, we were never given our quote. We were strung along by a series of emails, and then received no more responses. I have tried many times to reach out for the quote, and after that, to inquire as to what happened. Again, no response at all. Now, after waiting so long, we have to start the entire process over again, and as it is October, we essentially have no hope of getting a new roof this season. I really hope our current last through the winter. This is entire unprofessional behavior, and I grow so weary of companies that make promises and do not fulfil them. We should at the very least be treated with enough respect to be given an explanation as to why they cannot or will not perform the work."

FAQs for window service projects in Lockport, IL

If you have a problem with your window, such as broken glass, minor leaks, or a problem with your window being stuck, repairing the broken part might be a cheaper option than replacing the entire window. However, if you have a deteriorating window frame or major leaks, buying a new window will be the better long-term solution.

Window replacement can become costly, especially if you’re replacing your whole home. There are a few steps you can take to help save money on the bottom cost while still giving your windows a facelift. 

  • Replace multiple windows at once to bundle your purchase 

  • Inquire about discounts, coupons, or special offers

  • Consider window repair as soon as you see damage to help prevent the need for replacement

  • Maintain your windows often by inspecting your windows for drafts, leaks, and cracks

There are certain window repairs that are cost-effective to DIY and relatively simple for homeowners to tackle themselves. Tasks like replacing a screen, replacing a lock, or sealing a window are typically under $30 and take minimal time to do yourself. However, if you need to replace your window or repair a broken double pane, it’s best to call in a professional window replacement installer to lend a hand. Replacing the majority or all of the windows in your home is a time consuming job and best left to a professional.

Window replacement costs between $180 and $410 per window, or an average of $280 per window. However, your specific replacement job could cost as little as $100 or as much as $750. Factors such as frame material, the number of windows you need, and the type of glass you order all impact the overall cost. For example, simple double-glazed windows will cost $3 to $6 per square foot, but the stronger tempered glass ranges from $12 to $14 per square foot.

The time it takes to replace a window is a total of four to 15 weeks. This time includes your initial consultation, appointments for measuring, as well as ordering and manufacturing your windows. For a smaller job, you can expect the total timeline to be on the shorter end, but for a whole house window replacement, it might take longer (or be split into multiple install appointments). Once your windows are created and ready to be installed, your window installer will take 30 to 60 minutes per window to install.
