Testimonials from Happy Customers
“Professional service with competent installers! We love our windows!”
"The Beige Windows recommended by the salesman for the historic district are a perfect color match. We bought 17 windows and will need the 3rd floor completed soon. We have noticed an energy savings already and would recommend Keystone Window to anyone."
“We replaced our whole house with Energy Star certified Slocomb Window and Door Windows. The installers showed up on time and cleaned everything up. The detail and explanation of how the windows operate was top notch. Our attic is now a little cooler in this hot weather. We liked that the owners are hands on and local and not some big national company from out of the area.”
“What a difference new windows did to our air conditioning bill. The outside heat is barely noticeable inside, and the crew never stopped working. The caulking and capping really makes the windows look better than our old house.....My husband is an engineer and liked the specifications of "Slocomb Window and Door" windows over all others researched. A great investment so far!!!!!”
“We only needed a patio door and chose Keystone Window. The job took 3 hours and now the door opens and closes smoothly. The morning sun no longer comes through and heats up the kitchen floor. The salesman was not pushy and gave us 30 days to decide. We liked the softer sales pitch and the product was priced fairly.”
“Our windows (20) were installed in a 200 year old farmhouse. We were concerned about the stone outside and how the capping would match up. The head installer was a master with the aluminum and we are very pleased. The many drafts have been reduced and we would recommend Keystone to anyone. The owners are local and really made sure we were satisfied.”
“We only needed 3 basement windows and we liked Keystone's approach of no haggling and straight to the point. They were gone in 20 minutes or so and showed up 4 weeks later for the installation. We checked out Slocomb Window and Door and were comfortable knowing they have been in business for a long time. The owner was honest and you could tell he would go the extra mile to make us happy.”
“Fantastic job and the price we paid was actually the price they advertised. That was not the case when we shopped around through the 2-3 hour presentations. What a relief!! Good job Keystone.”
