Reviews
What customers say
Positive experiences include a smooth sale and installation; one homeowner also praises prompt responses and friendly after-sales help. One homeowner says installers left a door unable to close and later returned to fix it, but broke the flashing above the door and left it unrepaired; replacing another broken part took over a month, and months later a frame-replacement offer was impractical after exterior cladding and drywall were finished, so visible capping was put over the frame instead. Another customer reports windows that would not close properly and a patio-door muntin fallen between the panes; customer service later offered a repair agreement that satisfied both parties.

I am very satisfied with my experience with Vaillancourt. Both the sale and the installation went smoothly. Now all that's left is to get through the first winter!
