Need a structural beam letter in Chilliwack?
If you’re removing a load bearing wall, widening an opening, or adding onto your home, a stamped beam letter is often required for permit approval. We provide practical, code-compliant beam letters that help your project move forward quickly and confidently.

When Is a Beam Letter Required?
In Chilliwack, beam letters are commonly required when:
Removing a load bearing wall
Creating an open-concept layout
Installing a new LVL or steel beam
Adding a major addition
Modifying support posts
A properly engineered beam ensures loads are transferred safely to supporting structure below and complies with BCBC 2024 requirements.

Types of Projects We’ve Completed
We have provided beam letters for:
Wall removals in townhouses
Apartment and multi-unit residential buildings
Single-family homes
Large structural openings
Reinforcement of walls below new openings
Where existing drawings are available, we review them carefully. If drawings are not available, we attend site, take measurements, inspect the existing framing, and determine the structural system directly.
This ensures the beam design reflects actual site conditions, not assumptions.

Cost of a Beam Letter in Chilliwack
Most beam letters for residential projects in Chilliwack cost around $1,000, which is our typical minimum fee.
This generally includes:
Site visit
Measuring and documenting existing conditions
Structural design calculations
Internal design review
Issuance of a stamped beam letter
In some cases, we also complete a follow-up site review after installation to confirm the beam was installed according to the design. A field review report can then be provided confirming compliance.
More complex projects involving multiple beams, unusual loading, or significant foundation upgrades may require additional scope.
Practical Structural Solutions
Our background working hands-on in construction allows us to design beams that are practical to install, especially when space is limited and the surrounding finishes are complete.
We understand that most beam projects occur in lived-in homes. We aim to provide solutions that are structurally sound while minimizing disruption and unnecessary cost.
