Report
Marc was an excellent and very responsive communicator throughout the entire process! His pricing is fair and competitive and, as promised, there were no surprises from his end. His crew was thorough, professional and meticulous. We had all of the windows in our 1948 home (and 1960s addition) replaced at once. I get pretty anxious about having work done in our home, but Marc listened well, allayed my concerns and followed through on all of his commitments to us.
Our house had some surprises and complications that arose during our window install and Marc's crew was very balanced and thorough in their response and in finding solutions. His team does beautiful work, which impressed me throughout the project. We did have a couple of issues arise and Marc addressed everything right away, even personally coming by each time to make sure everything was done to our satisfaction. We give Highland Window Co. our highest recommendation!

We were 100% satisfied with the professional installation of windows and doors done by Highland Window Company in our 100 year old home. Because it was such a large project, we carefully examined their work along with other companies in the area and collected competitive quotes. We were impressed with the number of positive reviews on Google and Angie's list and found that their personal attention, knowledge and pricing beat the other companies we evaluated.
We are happy to report they came to do the job in the specified time frame, their installers were top notch, they did everything they said they would do and more and making sure their client is happy with the work is a priority for them. They also contracted with us to install gutters and that was a success as well. We highly recommend this company.

Marc has been very responsive and timely from start to finish. Really appreciate Marc's help with getting the requisite info ready to submit for the Energize CT rebate program. He and his installation team are true professionals. Very happy with our replacement windows and have already been recommending Highland to friends. Update: Just had our old basement windows replaced. Same level of service and craftsmanship as before. What a difference in the comfort level of the room. Should've done these with the first go around!

We couldn't be happier with the job that Marc Cowan and his team did with our windows. We had all 16 windows in our West Hartford home replaced by Highland, and they did outstanding work - quick, efficient and clean installation of high quality windows at a very reasonable price. Marc was a pleasure to work with - friendly, professional, responsive and trustworthy. Highly recommend Marc and his team!

We've had a great experience with Highland, and have used them on three occasions now. Marc was very helpful and informative, and once we decided to go through with window replacement, he walked us through the timeline and maintained a professional and courteous relationship with us all the way through installation. We love our new windows! Easy to use and easy to clean. Thanks, Marc!
