Windows and doors
Better Windows, Warmer Winters.
Home Renovation Contractors replaces windows and doors across Greater Montreal, Laval, Longueuil and the North and South Shores.
In Quebec, full-frame window replacement typically costs $500 to $1,500 per window installed in 2026, and insert (retrofit) installation $300 to $850 per window, depending on size, material and access.
In every Montreal borough, changing the size of an existing window or door opening, or creating a new one, requires a permit. Heritage sectors also regulate replacement windows on facades.
Window work is often combined with exterior renovation, insulation and painting and trim.

Choosing a frame
Window Frame Materials Compared.
Each material balances cost, durability and look.
| Frame | Strengths | Consider |
|---|---|---|
| PVC (vinyl) | Economical, good insulation, low maintenance | Limited exterior colours |
| Hybrid (PVC/aluminum) | Durable exterior colour | Higher price |
| Fibreglass | Very stable in cold, slim frames | Premium price |
| Wood or wood-aluminum | Traditional look for heritage buildings | More maintenance |
Look for ENERGY STAR certification for Quebec’s climate and consider triple glazing on north or noisy sides.
