Helpful answers
Frequently Asked Questions
Common questions about door & window installation in toronto & gta in Toronto and the GTA.
What's the difference between pre-hung and slab doors?
Pre-hung doors come with the frame, hinges, and often the hardware already attached, making installation faster and easier. Slab doors are just the door itself and require an existing frame. Pre-hung is recommended for most applications.
Do you install exterior doors?
Yes, we install all types of exterior doors including entry doors, patio doors, French doors, and sliding doors. We ensure proper weatherproofing, insulation, and security features.
Can you replace windows without damaging the exterior?
Yes, we specialize in window replacement with minimal disruption. For most applications, we can install new windows from the interior without disturbing exterior siding or brick.
How long does door/window installation take?
A single interior door typically takes 2-3 hours. Exterior doors take 3-4 hours. Window replacements vary but most take 1-2 hours per window. We'll provide a timeline for your specific project.
Do you handle permits for exterior work?
We can advise on permit requirements for your area. In most cases, window and door replacements don't require permits, but we'll verify based on your specific situation.
What about security features?
We install all security hardware including deadbolts, reinforced strike plates, and security hinges. For exterior doors, we recommend high-security locks and proper door reinforcement.
