Home Additions frequently asked questions

Home Additions FAQs

Common questions from Niagara homeowners about this service.

How long does a home addition take?+
A room addition typically takes 3–4 months. A full two-story addition or complex project can take 5–7 months. Design and permit approval add 4–8 weeks before construction begins.
Do I need to move out during construction?+
In most cases, you can remain in your home during construction. We sequence the work to maintain access and security. For very large additions, temporary relocation may be advisable for part of the project.
Will the addition match the rest of my house?+
Yes, matching your existing home is a priority. We carefully match rooflines, exterior cladding, windows, and interior finishes so the addition looks like an original part of the home.
What permits are required for a home addition in Ontario?+
Home additions require building, electrical, plumbing, and HVAC permits. We manage all permit applications and coordinate all required inspections throughout the project.
