Nelson, thank you for your generous offer. You surprised me with that & I truly truly appreciate it. You have made me very happy by the offer & I see that you stand behind your company & your work!
So often when something goes wrong we make sure to speak up but when everything goes right we forget to say thank you, so this is a big thank you for a job done right!
Just a quick note to say I love my new windows. What an improvement, they look great, and I can already notice there’s no drafts like with my old ones. I’d also like to mention what a fantastic job your installers did (Stan & Roma). They were very professional, efficient, respectful of my home and dedicated to perfection. Overall, I am very pleased with your company’s efficient service, professional staff and quality of products.
Went by the house today & saw the windows, they look AMAZING! I am especially fond of the lead-paned windows. They are so beautiful and feel exactly the same as the originals. I can't thank you enough!
Nelson, many thanks, few companies provide after market service the way you do. It's much appreciated!!
We want to let you know how happy we are with our new patio door. It looks great. We also want to thank the installers for doing such a good job. Looking forward to working with you on our next project!
We are extremely pleased with the door and the installation, particularly compared to our past experiences. The installer spent a lot of time making sure that everything was perfect…..we'll be replacing other windows in stages, so you'll hear from us again.
Janet & Nelson …..The door is beautiful! Thanks for doing what you said you would. I appreciate your professionalism (we have found this rare lately!) & the varnish was beyond very nice in the frigid weather.
