Great job on installing the first class windows in Queen Victoria Grant!

Your lead time on the units were realistic and everything arrived on time!!

Thank you Matt, for your time, patience and expertise! You worked so hard and yet left my house spotless... I was almost sure after the initial consultation that my choice was made, but had to wait for the other vendors to respond back to me. When you were done installing the incredible sturdy windows, I knew I had made the right decision. The quality finished products were superb!!

You were recommended to me and I will do the same to my friends.

Again, thank you so much!!!!

I am writing this letter of recommendation for Matt O'Brien, owner of a great local business. Having recently been in the market for new windows for our 20 year old house, I recently contacted Matt for an estimate. An appointment was made and Mr. O'Brien showed up promptly.

Matt discussed the variety of products that he had available and took thorough measurements. As promised, within a week, Matt had an estimate for me. I had also contacted several other local window companies, both large and small. The estimate that I received from Matt was considerably less for a superior product. Matt recommended Harvey Windows. After experiencing the winter we just did, I can say they made a significant difference in the warmth of our house and overall heating cost.

Throughout the ordering and installation of the windows, Matt was timely and courteous. Matt kept to a schedule and installation was done in a timely fashion. His work was professional and he was meticulous about his cleanup each day. My wife and I would not have even known the work was going on. Upon completion, to our satisfaction, Matt followed up on several occasions to make sure we were satisfied. On one occasion Matt came to the house when I was having difficulty with one of the windows. It turned out I was operating it incorrectly. Matt was patient and very helpful.

In closing, I would highly recommend O'Brien Windows and Doors for your installation. Service and professionalism are the best!

What a great experience we had working with you, Matt. The Harvey windows are a wonderful product and your service was impeccable. You are the ultimate professional and delivered exactly what you promised in a very timely fashion. Our sincerest thanks to you.

Dave and Helen - Glens Falls, NY

I can't thank you enough for the wonderful job you did with our recent window replacement project at our home. As I mentioned to you when we first met, I had contacted six different window companies to obtain bids to replace 18 windows at our home and our main concern was replacing a wood window with a vinyl window.

Although your price quote was not the lowest, I believe you get what you pay for. After meeting with you on several occasions and listening to your reassurances, I was convinced that not only were we getting a quality window with Harvey Windows, but equally important, we were getting an individual who would install the windows professionally, work neatly and meet our time line while standing behind the product. Everything that you promised came to fruition and the windows look great!

It is without hesitation, that I would highly recommend Matt to anyone who is considering any carpentry or window replacement In their home. Matt is well organized, easy to work with and more importantly, stays on the project until it's finished.

Matt, thanks again for doing a great job and making this difficult project so painless.

If anyone needs new windows for his home, I know where one can find the answer. During the 70's, I built a home on my family farm, which provides beautiful views. These improved views are now crystal clear. O'Brien Windows installed Harvey windows on three sides of my home. . I find myself discovering these views as if for the first time. The patio doors are wonderful. No drafts are found in my home because of 0'Brien installations.

This letter is to inform you that Matt O'Brien replaced windows for us in one of our properties. We are very pleased with the quality of work he did. the timeliness in which it was completed and the clean up during and after the job. I have given Matt's name to friends and do not hesitate to recommend his work.

Teressa - Queensbury, NY

Our family has known Matt O'Brien since March 2003. His brother, a general contractor who has done extensive work in our house, referred him to us. Last spring Matt installed eleven Harvey replacement windows in our home in Wilton, NY. He also noticed and fixed sealing problems with several windows that were installed by a workman whom we found to be less reliable. The windows look great, are easy to clean and have reduced the drafts into our home significantly.

This spring Matt installed new 80-inch wide Pella sliding glass door between our family room and deck. This job involved replacing several pieces of dry rotted wood with pressure-treated lumber. He also replaced four basement windows. which included building casements to avoid high costs associated with non-standard sized windows. Matt will replace our front door when the new one on order comes in.

We have found Matt O'Brien to be professional and courteous, and to demonstrate pride in his work. He believes in using quality materials, but has worked with us to control costs. I would recommend Matt's services to any of my friends, and encourage you to call us or stop by if you would like more information on the quality of his work.

On a number of occasions during the past three years we have contracted the services of Mr. Matthew O'Brien for general carpentry and window installation, and would recommend him without reservation or equivocation to anyone seeking and inquiring about his services.

Mr. O'Brien is thorough in his work, has an eye for the smallest of details, completes his work on schedule, is clean and neat, and stayed within the estimated cost of the job. Having used other carpenters and installers in the past we would say without hesitation that our experience with Mr. O'Brien has been the most positive one, and we frequently recommend him to family and friends when the need arises.

To anyone reading this recommendation; you will not go wrong in having Mr. O'Brien working on your home, office or building.

Sherye - Queensbury, NY

Last Fall I decided that I needed to replace three windows in my home before winter set in. After researching several product options and speaking to a few contractors I was not able to secure someone to expedite my project requirements. Through a friend I was put in contact with Matt O'Brien, owner of O'Brien Windows and Doors. After a brief conversation of what I wanted he followed up with a visit to my home to assess the job. He recommended the window replacements and described the work involved in detail to complete the job.

I am extremely pleased to recommend Mr. Matt O'Brien to my family, co-workers and friends. I found him to be very meticulous, dependable and his work to be superior. He spent a couple of days installing the windows and I appreciated that he kept the Work area neat. He was prompt each day and at the end of the installation reviewed all operating manuals and warranty information with me.

I look forward to future projects with Matt and his many skills and talents.
