Mark replaced the front door of my house and I couldn’t be happier with the result. He did an excellent job — the installation was done carefully and professionally, and the door looks great. Mark was reliable, easy to communicate with, and clearly takes pride in his work. I would highly recommend him to anyone needing door installation or similar work.
Thanks very much to Mark and Will for the great job on my window install. I needed Energy Star certified windows for the rebate program and federal loans that were availble at the time, and the Gentek windows installed both look great and meet the requrements.I did some other work along with the windows, but the difference in heat retention this winter is noteable. No more draughts and cool spots, like the 40+ year old windows they replaced. Perhaps most impressive is the difference in soundproofing; it is quieter inside the house with the windows closed than it was before.Highly professional and responsive throughout, and a local team which is a big for me. I prefer to work with smaller local contractors than franchises of national chains. Highly Recommend.
If I could give Mark 10 stars, I would! He replaced 8 windows in my rental house and my tenant was also impressed with Mark's professionalism and his personal approach. Mark's workmanship is top notch, he installed beautiful window casings with backband, which was more than I expected. I would definitely recommend his services, his expertise, his helpful suggestions and his competitive pricing. I will definitely hire him to do the basement windows next year !
Mark was quick to respond to my calls, was friendly and trustworthy. He did his work quickly and tidied up very well. I was thrilled with our new windows! I am also a repeat customer.
We had more than 20 windows replaced in our home, and we are very happy with the results. Mark and his assistant Will were professional, kept us well informed, and stayed organized throughout the project. They worked quickly and paid close attention to details, even on the high and hard-to-reach windows.We appreciated that it was easy to stay in our home while they worked. Their respectful and careful approach made everything go smoothly and without stress.We highly recommend Mark and his team for window replacement. Great service from start to finish!
