Window and Door Installation FAQ for Homeowners in the Greater Toronto Area
This installation FAQ is tailored for homeowners in Toronto, Durham Region, and York Region who want to understand the process before starting a project. Topics include site preparation, removal of old units, installation techniques, insulation and sealing materials, cleanup procedures, and warranty coverage—ensuring your new windows and doors deliver optimal performance from day one.
How long does a typical window or door installation take?
Most standard installations are completed in one day per product type. Larger or custom projects may take 2–3 days depending on site conditions and scope of work.
Do I need to be home during the installation?
It’s preferred that a homeowner is present at the start and end of the installation for access and a final walkthrough. Our team can coordinate around your schedule.
Is window and door installation messy?
OMEGA ensures minimal disruption to your home. We use drop cloths, protective barriers, and conduct a full site cleanup after completion.
Do I need to remove window treatments before installation?
Yes, please remove any curtains, blinds, or shutters beforehand to allow the installers clear access to the window or door openings.
Will my interior walls or trim be affected?
Our expert team installs using precision tools and techniques to minimize impact. In most cases, we maintain existing trim unless replacement is requested.
What’s included in a full installation service?
- Product delivery
- Removal of old units
- Expert installation and insulation
- Finishing and sealing
- Site cleanup and disposal
Are installations done year-round?
Yes, OMEGA installs windows and doors in all seasons. In winter, we use cold-weather sealants and work quickly to minimize heat loss.
Can you install in brick or stone homes?
Absolutely. We have extensive experience installing in brick, stone, stucco, and vinyl siding homes with custom-fit finishing solutions.
Do I need a building permit?
Typically no permit is needed for replacement windows or doors. However, if you’re modifying structural openings, a permit may be required. We’ll guide you through the process.
Are your installers certified?
Yes, all installers are factory-trained, insured, and experienced in CSA and local building code standards.
What’s the difference between retrofit and full-frame installation?
Retrofit keeps your existing frame intact; full-frame includes removing the entire window or door assembly for a brand-new frame and trim.
Do you offer disposal of old windows or doors?
Yes. Our team provides safe, eco-friendly disposal of all removed materials, included in every installation package.
What kind of sealant or insulation is used?

How do I prepare my home for installation day?
- Clear furniture and décor near openings
- Disarm security systems if connected
- Ensure pets are secured
This allows for efficient and safe access for the crew.
What if it rains on installation day?
We monitor weather closely. Light rain may not cause delays, but in the case of heavy downpours or strong winds, we’ll reschedule at no cost for your safety.
Do new installations increase home value?
Yes. Professionally installed energy-efficient windows and doors boost curb appeal, improve insulation, and can raise property resale value.
Is indoor air quality affected during installation?
We take precautions to reduce dust and debris. There’s no significant impact on indoor air quality during or after installation.
Do I need to schedule a post-installation inspection?
No need—our team performs a final walkthrough with you on-site, confirming fit, finish, and performance before leaving.

Are permits required for window or door replacement?
