Reviews
What customers say
Customers who described window work praised the results: a customer who bought four windows with installation included praised the team's work, and another said a whole-house redo looked better than expected with no issues after a year. A customer reported waiting more than 11 months for a warranty thermos replacement without hearing from the service department, while recalling good installation service five years earlier. One customer said sales and warranty documents were not available in English.

Frequently Asked Questions
How does Caron & Guay plan window installation?
A counsellor meets with customers in a store or at home to discuss their needs and recommend products. Caron & Guay says a certified measurer takes dimensions after a selection is made, then installers arrange the visit once production is complete.
Can existing window frames stay in place?
Caron & Guay generally advises against fitting new windows inside existing frames. It says frames may need to stay if existing brick or stone is supported by them, the walls are too thick, or special interior finishing is unavailable or difficult to remove.
Can customers outside Caron & Guay's branch regions still get its products?
Yes. Caron & Guay says its products are available through distributors across Québec; each distributor sets its own installation terms, and the company does not guarantee its certified installation service through them.
