Likely yes. Unlike some of our other markets, Montreal requires a permit to replace exterior windows and doors even with same-dimension, like-for-like models. Requirements and fees vary by borough, so we recommend confirming with your local permit office before starting a project.

Yes. Montreal has extensive heritage protection in boroughs like Westmount, Old Montreal, Outremont, and Le Plateau-Mont-Royal. Projects in these areas typically require review by the borough's heritage committee or the Conseil du patrimoine de Montréal, and materials like vinyl are often restricted in favour of options that match the building's original character. We can help source appropriate products, but recommend confirming your property's heritage status with your borough first.

Yes. Montreal's building bylaw requires residential windows and patio doors to be ENERGY STAR certified for the local climate zone, regardless of any rebate program. Our Marvin & Portatech products include ENERGY STAR certified options that meet this requirement.

Yes. Quebec's Rénoclimat program offers $150 per rough opening for ENERGY STAR certified window and door replacements. A pre-retrofit energy evaluation is required before any work begins, so register before you order.

Yes. Marvin's Ultimate and Modern lines offer extensive customization for size, shape, profile, and finish. Send us drawings or photos of any unusual opening and we'll work through the options with you.

A retrofit, sometimes called an insert installation, replaces the window itself while keeping the existing frame in place. A full-frame replacement removes the entire assembly down to the rough opening, allowing for better insulation and correction of any rot or moisture damage. The right choice depends on your existing frames and performance goals; your installer can advise after a site visit.

Lead times vary by product line and season. Standard Marvin orders typically range from 5 to 15 weeks, with spring and early summer being the busiest period. We'll confirm current lead times when we provide your quote.
