    I can't rave enough about the amazing job Marc and his team did. Down-to-earth, quick, professional, and detailed - they really took care of my home. I had a deadline in mind and they exceeded expectations, while always being quick with the communication. I would highly recommend them to anyone looking for new siding.

    Marc and the team at Highland did a fantastic job on the installation of 23 windows and siding at our house. The price, professionalism and attention to detail are unbeatable!!!

    Met with a couple of contractors for a large project and after a lot of research went with Marc and Highland Window Company. Bottom line very happy and completely satisfied that we did. Marc walked us step by step through what we could expect as he oversaw a new roof, new windows (18), a new front door, new siding & soffits, and new gutters and downspouts. Each of the four different crews that came for each stage of the project were professional, polite, and skilled. Cleanup was done daily and hardly impacted our daily routine. Marc was out on the site very often throughout the process and answered all questions and concerns. We actually had one minor glitch on the project when a manufacturer sent a wrongly sized part for the storm door frame. Definitely still deserves five stars as Marc stayed on top of it and communicated to us regularly until it was resolved perfectly. Waited a couple of months to post this to make sure nothing popped up and nothing has - love the look, functionality, and quality of the work.

    Highland Window Company just finished installing 30 windows in our 1931 Dutch Cape, and we couldn’t be happier! Several years ago, we had a different window company come to our house, take over three hours to give an estimate and the salesman would not leave unless we signed the contract, (the estimate was over $30K. ). We had to tell him to leave. It was not a good experience, so we did not pursue further until we reached a point where a stiff breeze was blowing through our living room last January. Our experience with Highland , specifically with owner Marc Cowan, was completely different. Marc spent 45 minutes chatting with us and looking around our house, showing us a beautiful sample window and giving us an incredibly reasonable estimate. He was so charming and personable, we didn’t want him to leave! No pressure, just a great quality window from an honest and kind business owner. Highland had our windows manufactured and installed within a month. The crew (Neil, Hilton and Tom) were neat, skillful, professional and gracious, installing 20 windows day one!!! They left our house cleaner than when they arrived. We can’t recommend Highland Window Company any higher. Marc is a great pleasure to work with and we will definitely call him with our future home renovation needs. Amanda and Paul Riley Danbury, CT

    Highland Windows just completed replacing 9 windows in our 4 bedrooms. We chose the Harvey Majesty windows, as these seemed the best at matching our colonial house. The overall job was six weeks from order to completed installation, which was great. The install took two days, and the workers cleaned everything up quite well each day. During the installation, we asked them to do a couple extra things for us, which they were happy to accommodate! Overall a great job at a fair price (we shopped around before we picked Highland). Great company to work with.

    I obtained several estimates to replace a number of windows in our house. Not only was Highland the fastest to respond and provide an estimate, but they had the best price. They came when they said they would and did the work exactly as stated. They worked fast, quietly, left no mess and the end product was A+ quality. I’ll surely have them back for more work.

    I researched and met with several people/companies for window replacements before Marc and his Highland Window Company was referred to me. I have since used him several times for window replacements during several phases of renovations to my 3 family house. He provides excellent customer service, he is not pushy, he is fair and very easy to work with. He and his crew are clean, pleasant and quick. They did an amazing job. He also provides financing. I would recommend them to anyone and would definitely use them again.

    Marc and his team are the best. They've helped me personally with multiple projects and many I have referred. Solid work and everyone I have met from his team shares his customer service brilliance. Well done

    Affordable price and super professional installation. Marc came to our house to give us an estimation and walked with us in and around the house several times to make sure all we need is covered and to assure that we are in sync. After saving us money on things we thought we need and didn't really, Marc gave us an estimation for the entire house. After the windows were manufactured for our house Highland company installed the windows in a no less than perfect way, while making sure that the insulation is perfect and that we are happy in every step they make. No compromise on any of the installation steps or quality - the team cleaned daily during and after they finished their work, collected the old fixtures and left a clean house with new windows, installed to perfection. Thank you for a great job. You are the best!!!
