Sizing the framing for your project

We size joists, beams, posts, and footings for the project’s loads and spans, checking for continuous support into the soil or house structure. For a structure attached to the house, we check the individual home’s framing and foundation before planning alterations.

Connection details and materials

We detail the ledger attachment, joist hangers, fasteners, post connections, lateral connections, and guard-post connections. The plans specify pressure-treated lumber, corrosion-resistant fasteners, and guard-post connectors. Member sizing and connection details belong together: the plans need to show both the framing dimensions and how the pieces connect.

Ground conditions at the property

Soil-related movement can vary across Walnut Creek. High shrink-swell Clear Lake clay occurs near the Civic Center and Walden Road, while Cropley clay occurs at the Rossmoor Golden Rain Road entrance. We account for the property’s soil conditions when sizing footings rather than treating every location in town as the same.

How It Works

The process is short and the same every time:

  1. Tell Us What You Need

    A short call is enough for us to understand the project and what it will take.

  2. Research First

    We review what's already on file, records, plans, and prior work, before anyone heads out.

  3. Clear, Written Price

    You get the scope and the price in writing before any work starts. No surprises.

In practice, on a job like this:

  • Prepare the framing and footing plans, connection details, material schedule, and calculation package; provide sealed drawings when required.
  • Provide optional design follow-up during construction and coordinate with inspections.
