Testimonials

Once again I want to thank you and all the people working on our church windows. What a fine improvement the windows have been to our church sanctuary. We immediately noticed improved natural light, less noise intrusion from the busy road out front, much warmer and more comfortable temperatures in this Michigan weather. Of course what people always comment about is the beautiful design We feel that the stained-glass cross in the window makes the sanctuary a more reverent place to worship.

We would like to personally recommend and endorse Tim Luch at Cornerstone Windows.

He has helped us take a huge step in making our house a wonderful home. The addition of over a dozen new windows has enhanced the quality of life in our family tremendously. We have owned our house for 14 years, are the third owners, and the house was built 22 years ago. Although a model home in our sub-division, it had standard side-by-side slider windows in all rooms. The heating and air-conditioning bills were sky-high.

After consulting with a couple firms about replacing the windows, we called Tim. He was more than patient explaining options and features. Never any pressure, we were confident in his advice and abilities. We had heard and experienced some horror stories about contractors and window companies in general. Tim recommended side-by-side double-hung windows for our bedrooms, which after they were installed we absolutely loved.

We had him supply and install a 5' sliding patio door and a custom 6' window in the family room with casement openings on each side and a 4' by 5' clear glass center. This along with a special DreamGlass window at the opposite end of the family room has opened up the light in this dark area and is an amazing addition.

When Tim ran into a house-structure problem with a new cut-out for our specialty window, he discussed options with us and spent an extra full day re-routing interior duct work to make the window fit where we wanted it—at no additional charge.

Now that the installation is complete, the one thing we didn't expect was the quiet. The house is so much more quiet, especially at night. We live in line with an approach to an airport and the planes could be heard late at night as we were trying to get to sleep. No more with the triple-glazed windows in our bedrooms. Additionally our heating and cooling bills are down considerably.

We are extremely happy with our windows and doors from Cornerstone Windows and would highly recommend them to anyone.

This letter is written as an endorsement of the fine job Tim and Cornerstone Windows did in replacing three windows in the front of our home. The professionalism, timeliness and work ethic displayed by Tim and his staff was exemplary. We will not hesitate to call upon Cornerstone Windows when we are ready to replace the remaining windows in our home.

We are extremely pleased with the look of our home since replacing our front doors, living room windows and two bedroom windows. We absolutely LOVE the casement windows which were installed in our bedrooms!

We would not hesitate to recommend Cornerstone Windows to anyone in the market for replacement windows.

We can't recommend Tim Luch and Cornerstone Windows highly enough! The scope of our job included a new kitchen/family room addition, significant renovations in two other rooms, siding and windows for the entire house and garage, new furnace with ducts and air conditioning unit. We also had a large vinyl front porch added across the entire front of the house. Family and neighbors say it's awesome! Everything looks great! We have a beautiful, totally new looking home!

They got the job done in less than 4 months, and cleaned up their work area daily.

When we first started talking about doing this project we were told horror stories about contractors. After meetings with several who never got back to us when they said they would, we were not looking forward to the ordeal. Tim Luch always showed up for appointments and returned our calls. He genuinely wanted to do a good job, and they did!
