Cambridge's Trusted Addition Framing Contractor — Galt, Preston & Hespeler
Home addition framing in Cambridge covers second-floor additions, rear additions, side additions, garage conversions, and in-law suite framing built to Ontario Building Code and left inspection-ready.
Home Addition Framing Cambridge needs clean layout, code-aware framing, and an inspection-ready handoff from the start. Cambridge is three communities in one — Galt, Preston, and Hespeler — each with its own housing stock, its own character, and its own addition framing needs. From the heritage mill town homes along the Grand River in Galt to the post-war family streets in Preston and the growing neighbourhoods in Hespeler, homeowners across Cambridge are choosing to expand rather than move.
Timberr Framing is a fully licensed home addition framing contractor serving Cambridge, including Galt, Preston, Hespeler, and the surrounding Waterloo Region. We frame second-floor additions, rear additions, side additions, garage conversions, and in-law suites — all built to Ontario Building Code and left inspection-ready.
We carry $5M in liability insurance, are registered with WSIB, and hold a 5.0 rating across 40 Google reviews and 11 HomeStars reviews, and bring the right approach to every project — whether it is tying a modern addition into a century-old Galt home or building a clean second storey on a Hespeler bungalow.
Whether you need more space for a growing family, want to add rental income with a secondary suite, or are converting a garage into livable square footage — Timberr Framing delivers addition framing in Cambridge that is structurally sound, code-compliant, and ready for the next trades.

Our Addition Framing Services In Cambridge

Second-Floor Addition Framing
Complete structural framing for second-floor additions — including new floor systems, load-bearing walls, roof framing, and structural tie-ins to your existing home. We work with your architect and engineer to execute the plan with precision.
Cambridge has a large stock of bungalows and storey-and-a-half homes across all three communities that are well-suited for second-floor addition framing. The existing foundation and first-floor structure must support the new load — Timberr Framing evaluates everything before framing begins.

Rear Addition Framing
Rear additions are the most popular way to expand living space while keeping the street-facing facade unchanged. We frame rear bump-outs, kitchen extensions, family room additions, and full-width rear builds — properly tied into your existing structure.
All rear addition framing in Cambridge is completed to Ontario Building Code with clean tie-ins to the original frame.

Side Addition Framing
Side additions add usable square footage by extending into your side yard. These builds require careful attention to setback requirements and structural integration with the existing home.
Timberr Framing handles the structural framing for side additions of all sizes across Cambridge — from narrow extensions on tighter Galt lots to full-width builds in Preston and Hespeler.

Garage Conversion & Addition Framing
Converting an existing garage into living space or building a new attached garage addition requires structural framing that meets code — especially if you are adding living space above.
We frame garage-to-suite conversions, garage additions with second-floor living space, and standalone garage structures. All work is inspection-ready.

In-Law Suite & Secondary Suite Framing
Growing families and rising property values across Cambridge are driving demand for in-law suites and secondary suites. The framing must meet Ontario Building Code requirements for separate dwelling units — including fire separation, egress, and sound isolation framing.
Timberr Framing understands the code requirements for secondary suites and frames accordingly.

Frequently Asked Questions — Home Addition Framing Cambridge
What does home addition framing cost in Cambridge?
Addition framing costs in Cambridge depend on the type of addition, the square footage, and the complexity of the structural work — particularly when tying into older heritage construction in Galt or Preston.
A rear addition frame is typically the most straightforward option. Second-floor additions cost more because the existing foundation and first-floor structure must be confirmed to handle the added load.
Garage conversions and in-law suites vary based on the scope of structural modifications.
The most reliable way to get an accurate price is to contact Timberr Framing for a free written quote. We assess your plans and your home before pricing — no guesswork.

If your project involves structural framing for an addition of any type, contact us to discuss.
How long does addition framing take?
Timeline varies by project. A standard rear addition frame typically takes one to two weeks. A full second-floor addition generally requires two to four weeks depending on size and complexity.
Timberr Framing provides a clear project schedule during quoting and communicates throughout the build so you always know where things stand.
Do I need a structural engineer?
In most cases, yes. Any addition involving load-bearing changes, new foundation work, or a second-floor build will require structural engineering. The City of Cambridge requires engineered drawings as part of the building permit application.
Timberr Framing is experienced coordinating with structural engineers and frames to their specifications. We ensure the work is ready for inspection.
Can you tie a new addition into my existing home?
Yes — and this is one of the most important aspects of any addition project. Cambridge's diverse housing stock — from heritage Galt homes to mid-century Preston builds — means every tie-in is different.
Timberr Framing specializes in structural tie-ins between new additions and existing homes. We assess your existing framing, identify load paths, and connect the new structure so it performs as one integrated unit.
Do I need a building permit for framing?
Yes. Any home addition in Cambridge requires a building permit from the City of Cambridge before construction begins. This includes second-floor additions, rear additions, side additions, garage conversions, and in-law suites.
Timberr Framing builds every addition to Ontario Building Code and ensures all work is inspection-ready at handoff. Permits are typically handled by the homeowner or GC — we frame to the exact specs on your permit drawings.
What is the difference between an addition and a renovation?
A home addition adds new square footage to your home — a new room, floor, or extension. A renovation changes existing space without expanding the footprint — like removing walls or re-framing interiors.
Timberr Framing handles both. For renovation framing, see our renovation framing services. For additions, you are in the right place.
Do you work with builders and general contractors?
Yes. Timberr Framing regularly works as a framing subcontractor for general contractors managing home addition projects across Cambridge and Waterloo Region.
We understand the scheduling requirements of residential builds and coordinate smoothly with other trades. If you are a GC looking for a reliable addition framing sub, get in touch to discuss your upcoming work.
What areas do you serve?
Can you frame an in-law suite that meets Ontario code for a secondary suite?
Yes. Ontario Building Code has specific requirements for secondary suites including fire separation, sound transmission ratings, separate egress, and minimum ceiling heights. The framing must be designed around all of these requirements from the outset.
Timberr Framing understands secondary dwelling unit code requirements and frames accordingly — including fire-rated wall assemblies, sound isolation framing, and proper egress window framing. All work is left inspection-ready.
