Your quote
One fixed price. In writing. Before you commit.
- Free scope review — you pay nothing to find out what your project needs
- A fixed price for a defined scope; additional work is only ever quoted, never surprise-billed
- Your quote stays valid for 30 days while you line up your contractor
- Plan-check correction rounds included per the proposal
Signs your remodel needs engineering
- Any bearing wall is moving, shrinking or disappearing
- You're cutting into floor, ceiling or roof framing
- The plan checker wrote "provide structural calculations" on your submittal
- Your contractor or architect asked for beam sizes, posts or holdowns
- The house is older and the remodel touches the framing

Deliverables
What you receive
A complete, engineer-reviewed structural package — the same documents a full-service firm produces, delivered through your project dashboard.
What you receive
Structural calculations
Gravity and lateral calculations that match the drawings, member by member, so plan checkers can follow the load path.
Details & connections
Beam-to-post, holdown, footing and connection details your framer can build from — no guesswork on site.
Plus permit-correction responses and revisions through the same project. Get your quote →
Pricing, honestly
What actually drives the price
No two projects price the same — these are the factors our engineers scope. You get one fixed number after a free review, not an hourly meter.
How many walls and openings
Each new beam, post and holdown is designed and detailed individually.
One story or two
Loads stack. Work on the first floor of a two-story home carries more design work.
Seismic bracing
Removing walls can remove earthquake bracing — California plan checkers look for the replacement.
Condition of the existing structure
Older framing and foundations sometimes need verification or upgrades along the way.
The risk is on us: free scope review, fixed price, and no commitment until you accept.

Built like software, reviewed like a firm.
The engineering is the same discipline you'd expect from any licensed structural firm. The way you order it, track it and receive it is not.

Before you ask
What does remodel engineering cost?+
Every remodel is quoted after a free scope review — one fixed price for a defined scope. Submitting your project costs nothing and you're not committed until you accept the proposal.
My permit application got flagged for structural calcs. Can you help?+
Yes — that's one of the most common projects we take. Upload the plan-check letter and your drawings; we'll respond with the engineering the city asked for, and correction rounds are included per your proposal.
Do I need finished architectural plans first?+
No. Plans help us quote faster, but photos, sketches and dimensions are enough to define scope for many remodels. We'll list anything else we need in the proposal.
Who does the engineering?+
Licensed California engineers. Every project is reviewed and approved by the engineer responsible for the work — approval is never automated — and documents are signed and sealed where required.
Your Remodel, Engineered — Before the Permit Counter Asks.
Three questions, a free scope review, and a fixed-price quote — usually within one business day.
No commitment required to submit a project for review.
