What is a hybrid window, and why is it popular?

A hybrid window combines a PVC frame on the inside for insulation and easy maintenance with an aluminum frame on the outside for weather resistance. It offers excellent value for money, all standard configurations, and a wide range of colours, including black, which is currently in high demand.

Are Portes et Fenêtres Verdun windows ENERGY STAR certified and eligible for grants?

Yes, our products are ENERGY STAR certified, which may make you eligible for certain government grants for energy-efficient renovations. Programs change over time, so your representative will inform you of the available financial assistance at the time of your project.

When should you replace the windows in your home?

A window generally has a lifespan of 15 to 20 years. Several signs may indicate that it is time to replace it: condensation between the panes (broken sealed glass unit), drafts, rising energy bills, difficulty opening or closing, or visible frame deterioration. If you notice one or more of these signs, a free evaluation can confirm whether replacement is recommended.

Why is there fog or condensation on my windows?

Condensation on windows can have several causes.
Inside the home: indoor humidity is too high from cooking, showers, plants, etc., and condenses on the cold glass surface. This is normal in winter and can usually be solved with better ventilation.
Between the two panes: this means the seal of the insulated glass unit has failed. The window has lost its insulating performance and should be replaced.
Outside: this is actually a good sign — it means your windows are well insulated.

How do I choose the right type of window for my home?

The choice is based on three main criteria: the material, the type of opening, and the style of your home.
PVC is an affordable option, aluminum offers excellent resistance, and hybrid windows combine the best of both worlds. Casement, awning, hung, or sliding windows each offer different benefits in terms of ventilation, security, and style.
See our detailed guide or ask a Portes et Fenêtres Verdun advisor for advice.

How to prepare your home before installing doors and windows?

A renovation can create dust. A few simple steps can help protect your home. Before the installers arrive, please remember to:
1. remove blinds and curtains,
2. clear at least 4 feet of space inside and outside each opening,
3. cover nearby furniture, floors, and plants with drop cloths or sheets.

How to remove the screen from a single- or double-hung window?

First, unlock the latches, then open the sash halfway. Release the side latches, tilt the sash 90 degrees inward, and lift one side while rotating it to disengage the sash pivot. Remove the sash and place it upright.
Finally, using the tabs at the bottom of the screen, gently lift it upward. Detailed demonstration here.

How to choose and install a patio door?

Choosing a patio door depends on the configuration (2, 3, or 4 panels, left or right opening), the material (PVC, hybrid, or aluminum), the type of glass (double or triple glazing, Low-E), and the security hardware.
Installation requires precise measurements, a perfectly level sill, and watertight caulking. It is carried out by our teams to ensure proper sealing and preserve the warranty.

Can you install an exterior door yourself, and when should you call a professional?

Installing an exterior door involves several technical steps: removing the mouldings, frame, and sill; positioning the door, adding shims, and constantly checking the level and alignment; securing the jamb, insulating around the frame, caulking, and installing the hardware.
A poorly adjusted installation can lead to heat loss, water infiltration, and void the manufacturer’s warranty. For a long-lasting result, we recommend professional installation. See our complete guide.

How to measure a window for replacement?

Measure the height in three places: left, centre, and right, and keep the smallest measurement. Do the same for the width: top, centre, and bottom. This method accounts for slightly warped frames. For a full replacement, the best option is still an on-site measurement by a Portes et Fenêtres Verdun advisor. It’s free and ensures a precise fit.

What grants or financial assistance are available to replace my doors and windows in Quebec?
