In May of 2019, Seiffert replaced 33 windows and 6 doors at our house in Davenport with new Marvin units. We wanted the new units to look like the old Pella windows complete with inner wood trim and the same exterior finish as the existing. Jeremy from Seiffert's QC Windows team spent a great deal of time with us investigating the windows we had and working with us and Marvin to arrive at the optimal solution. The new windows and doors all fit perfectly and look great. We worked with Silver Creek Construction on the installation and they did a superior job.
Our 1926 home need replacement casement windows which had to open in because of outdoor awnings and Marvin WIndows were the only company who could provide them. Jeremy at Seiffert was great! He answered every question I had and took care to exactly measure every window opening as they weren't uniform. The windows arrived when promised and our installer braved the cold weather to remove the old windows and install the new ones. We're VERY happy with the windows and the service!
Chuck and I want you to know how happy we are with our new windows. The attention and customer service we received was outstanding! The installers did a great job with our siding as they replaced the back windows. Thanks to you and the boys!
Seiffert offers a great line of quality products and really friendly and knowledgeable staff. We've worked with them on a couple different projects and were really pleased with the materials we purchased but even more so with the incredible service. They go above and beyond your expectations!
My Marvin Windows are the showpiece of my 1940 house. I asked that the original windows be duplicated to match the integrity of the house and Marvin answered the call. Not only did they do a beautiful job on the two corner windows that face each other but the finish on the inside was matched perfectly to my inside trim. I also love to stand in front of them and watch the snow fall and not feel one degree of cold coming in! The bedroom windows were done in the Integrity Line and were also a delight. Thank you Marvin and Seiffert....keep up the great work.
