Home Addition Framing Markham — Licensed, Insured & 5-Star Rated

Addition framing costs in Markham depend on the addition type, total square footage, and structural complexity of the project.

Rear additions are typically the most straightforward and cost-effective to frame. Second-floor additions cost more because the existing foundation and first floor must be assessed — and potentially reinforced — to support the new load.

In-law suites and garage conversions vary based on scope and code requirements. For an accurate price, contact Timberr Framing for a free detailed quote based on your specific project.
