Great experience! Denis was accommodating and great at communicating updates. He sealed our very large windows which others weren’t willing to even look at.

Denis did a fantastic job with our window and door repairs. He handled our window repair, patio door, and storm door with absolute professionalism. Everything looks great, functions smoothly, and works exactly like it should. He’s efficient, knowledgeable, and reliable. Highly recommend his services if you want the job done right!

Denis from Daybreak Seals did an excellent job repairing the caulking around our windows. He was prompt, professional, and clearly knew what he was doing. He walked us through what had failed, explained the fix, and worked efficiently without cutting corners. The finished work looks clean and solid, and you can tell it was done with care. It’s a relief to finally have this taken care of, especially with how the Chicago weather has been lately. I’d absolutely recommend Daybreak Seals to anyone dealing with window leaks or worn-out exterior caulking.

Details: 1 window • Water is leaking in • Window sealing • Double hung (slides up and down) • Residential

After sending our window leak pictures, Dan came in, analyzed and went straight to work. Work was efficient and effective. Would bring him in for future projects without a doubt!
