Homeowner Reviews

“The installation crew was awesome - they did a very good job of ensuring its done right. Did not rush through, patiently worked on each window, even though it involved them coming over an extra day to finish it up. Awesome work, and would recommend them definitely.”

“Dennis and the installers both did a fantastic job!”

“The installation crew took the time to do the install right the first time and focused on attention to detail. They worked hard the entire time, but did not rush just to get the job done and move on. They cared about the quality of the work they performed and the result shows.”

“Steven Stephen”

“Simply THE BEST !!”

“Very satisfied and highly recommend.”

“The entire staff went above and beyond from Nancy to the workers on site”

“Responsiveness, customer service, professionalism, quality of work, quality of products”

“Quality of windows and doors and excellent installation.”

“Dennis Williams gave the estimate and arranged the installation. He was direct, honest and thorough in describing and explaining everything. Robert, Kevin, Steve and Nathan did an exceptional job of installation. I don't believe any installers could beat that group in performance, knowledge, and experience.”

“The entire experience was excellent. The sales person was very knowledgeable and professional, as were the installers. I really love my new windows!”

“Already recommended them to several of my neighbors.”

“Everyone I had personal contact with/ Exceptional in every way.”

“Robert and his installation crew were up most professionals. Very satisfied with there workmanship. Robert will definitely finish up the rest of my windows in my house when the next time comes!!!”

“This was our 2nd time using Pinnacle Window &Siding Co. It was a great experience from the first meeting, scheduling and final install. The staff is professional and friendly. We are enjoying our beautiful new windows!”

“I spoke to at least 6 companies and Dennis Williams by far was the most knowledgeable and really listened to what I wanted and supplied me with options based on my requirements. The others pushed certain brands of windows and didn't listen to my needs.”

“Dennis Williams, Robert (measured windows) and the GREAT installation crew!!! Thanks”

“The professionalism of the installation team and the high attention to detail. The windows look great with no fit or cosmetic issues.”

“We are extremely please with the professional work completed. The Sales process with John and the install by Hector and his team were first class. We are planning to complete 12 more windows with this company in late 2019.”

“Terrific experience with Pinnacle! Professional and knowledgeable about product. Communicated delivery details and installation schedule.”

“Robert and his helper (sorry I didn't catch his name) did a great job with the installation.”

“We had a great experience with Pinnacle. These guys are the best! We had our windows and front door replaced and could not be happier. The whole process from sales to installation was very easy and painless. Everyone was very informative and professional plus the final product looks great. We would highly recommend Pinnacle to anyone looking for new windows and doors.”

“Wow! What a fabulous company to do business with! This was hands down, one of the best contractor experiences we have had in a very long time. With a focus on quality, integrity and customer service, Pinnacle Window & Siding is definitely a rare find in today's business environment. We experienced nothing short of professionalism from our first meeting with salesman John Fitzgerald, to the wonderful crew (Robert, Kevin and Steve) who couldn't have been more skilled, efficient and courteous, to the amazing owner Mr. Lee Fuller. We purchased the Okna Eco-Pro 600 Series windows and love them! Oh, and how many company owners today, take the time to call their customers before the end of the day to make sure that they are satisfied?!! Thank you Lee Fuller! Know that we appreciate your dedication to excellence! Wish we would have found you ten years ago!”

“Everyone at Pinnacle has given me excellent service. They kept me informed through out the process. Outstanding customer service.”

“The complete installation process.”

“We had a great experience with Pinnacle Windows. The sales team answered all our questions and made suggestions based on our needs. The installation team was exceptional. They were organized, very clean, and efficient. I would highly recommend Pinnacle Windows to anyone.”

“Quality & care of window purchase decision as well as the install. I was not an easy customer and we never ever felt any sales pressure. The process was like working with a friend. Additionally, the install was just flawless...from replacing rotten wood, to keeping all areas of the home calm and clean, great caulking job and no drama...just a beautiful finished product.”

“Mr. Fuller”

“We just had 26 windows replaced by Pinnacle, and we could not be more pleased with the entire experience. We received quotes from several companies and chose Pinnacle because of the quality of the products they offer and the quality of the service they provide. They do all of their installations with their own staff and stand behind the windows and the work with a lifetime guarantee. We love the new windows - they have made a huge improvement in the comfort level in our house. Dennis was our salesman, and he walked us through several options, without a hard sell, and was very responsive through the entire process of getting a quote and placing the order. As soon as our windows were ready for installation, Robert called us and arranged the installation. He and Steve came with a crew and replaced our windows in one day. They handled everything, were very professional and conscientious, kept us informed as they went along, and took care of all the clean up, even hauling away all of our old screens. The most impressive thing is that there was an error in sizing on of our windows. They had received the wrong sized window. Robert noticed the error right away, did not touch that window, and thoroughly explained how they would order a new window and the timeline for getting it to us. We knew exactly what to expect, and as soon soon as the correct window came in (when he said it would), Robert came back and finished the installation. We will definitely recommend Pinnacle. The quality of the products and the work is excellent. Most impressively, they stand behind their work and they do what they say they will do, when they say they will do it.”

“After receiving several estimates on several custom windows and unique windows, we selected Pinnacle Windows and couldn?t be happier. Hector and team did a wonderful job with the installation, worked very hard, and were careful around furniture and landscaping. Lee was great with quoting and following up after the installation was complete. I will definitely use Pinnacle Windows again for our next window project.”

“Everyone at Pinnacle from the salesman, the management to the on site crew were all knowledgeable and professional throughout the process. They showed up on time, took care of the install professionally, cleaned up after they were done. An excellent experience all around. I would highly recommend them.”

“The entire team was excellent, but we would like to give special recognition to Robert Cole, a consummate craftsman who takes great pride in doing high quality work.”
