What People Are Saying…
We strongly recommend John’s window inserts and excellent workmanship.
John is an AMAZING person and the window inserts he provided do a wonderful insulation job, especially these days when its close to -30 outside.
The temperature in our large room with ceiling vaulted windows got quite a few degrees better with less heating being required and there is absolutely no condensation anymore, no matter the humidity setting inside the house.
The best part: all for a small fraction of what new triple window panes would have cost.
Thank You, John!
