Why Quality Doors and Windows Matter for Insulation
Your doors and windows act as the primary shield for your house. Old windows and doors often lose their ability to block heat transfer. Over time, wood frames rot and seals fail. This creates drafts that make your living space uncomfortable. Choosing energy efficient upgrades is a smart move for any property owner.
A complete replacement ensures your home stays protected. Doormatic provides energy star rated products designed for harsh climates. Modern steel entry doors and fiberglass doors feature thick insulation. These materials prevent cold air from seeping into your entryway. Upgrading your windows and doors setup also improves your home’s curb appeal. New installations provide a better seal than any DIY repair.

Step-by-Step Window Installation Process
Our team follows a strict window installation process to ensure your home is sealed. We treat every house with respect during the whole process.
1. Removing Old Windows and Doors
We start by carefully removing the existing windows and exterior doors. Our team avoids damaging your siding or interior trim. We clear away old caulk and debris from the opening. This creates a clean surface for the new seal.
2. Preparing the Opening
Our experienced installers check the structural integrity of the frame. We ensure the opening is square and level. We apply a waterproof membrane to protect against moisture. This step is vital for preventing rot in the future.
3. Installing the New Sealed Glass Unit
We set the new window or door into the opening. Our team uses shims to ensure a perfect level. We then secure the frame to the house structure. For windows doors, we ensure the sealed glass unit is protected during this phase.
4. Applying Insulation and Sealant
We fill the gaps around the frame with professional-grade insulating foam. This blocks air leaks and prevents drafts. We then apply high-quality caulk to the exterior. This creates a secondary barrier against rain and wind.
5. Adding the Perfect Finishing Touches
We install the trim and ensure the hardware works smoothly. Our sales representative checks the operation of the locks and handles. We clean the glass and the work area before we finish. You get fresh air when you want it and a tight seal when you don’t.
Exploring Different Window Types for Winter
Different window types offer various levels of protection. You must choose a style that fits your home’s architecture.
- Double Hung: These are classic and offer easy cleaning.
- Tilt and Turn: These provide excellent sealing and security.
- Casement: These press tightly against the frame when closed for a superior seal.
- Custom Windows: We can create unique shapes to match your aesthetic.
- DraftLOCK Windows: Very attractive and energy efficient windows on the market.
Each right window choice helps reduce harmful uv rays and noise. Natural light fills your home without the cold breeze. Doormatic ensures all your windows are equipped with the best glass units.

Frequently Asked Questions
How do new windows help lower my cooling bills?
High quality windows with low e coatings block heat from the sun. This keeps your home cooler in the summer. While they insulate in the winter, they also reduce the load on your air conditioner during hot months.
What is the difference between double hung and casement windows?
Double hung windows have two sashes that move up and down. Casement windows swing outward and use a crank. Casement windows often provide a tighter seal because the sash presses directly against the frame.
How long does the window installation process take?
Most installations take one to two days depending on the number of units. The window installers will also require easy access to all rooms where new units are going to be installed.
Why should I choose fiberglass doors over wood?
Fiberglass doors do not rot, rust, or warp. They offer better insulation than wood and require minimal maintenance. They are an excellent choice for the wet and cold Canadian climate.
Can I install windows myself to save on window replacement costs?
DIY installation often leads to gaps and leaks. This can void your warranty and cause water damage. Using professional installers ensures the job is done right and your home remains energy efficient.
