Built square.
Built to last.
Cornerstone Construction handles new builds, remodels, and additions across the North Valley. Run by Matt Rappa, on site and on the phone, from the first walk to the final walkthrough.
One contractor, whole project
From ground-up builds to the repair jobs nobody calls back about, handled under one roof with one point of contact.
New Construction
Ground-up builds managed from plans to final walkthrough: site work, framing, trades, and finish, coordinated under one contract.
- Custom homes
- Shops & garages
- Plan-to-finish management
Remodels
Whole-home and single-room remodels that respect the house you have while building the one you want.

More square footage done right: additions and accessory dwelling units that match the existing structure and meet code cleanly.
- Room additions
- ADUs & granny units
- Garage conversions
Kitchens & Baths
The two rooms that sell a house and shape every day in it. Layout, cabinetry, tile, and fixtures, sequenced so the mess stays short.
- Kitchen remodels
- Bathroom remodels
- Fixture & finish upgrades
Decks & Exterior
Decks, patio covers, siding, and exterior repairs built for valley summers and wet winters.
- Decks & patio covers

Repairs & Projects
The in-between jobs other contractors will not call back about: structural fixes, dry rot, doors, drywall, and punch lists.
- Structural & dry rot repair
- Doors & windows
- Punch-list work
The first stone sets every wall
A cornerstone is what the rest of the building lines up on. That is how we treat the first conversation, the first bid, and the first day on site.
Matt runs the job
You deal with the person building your project, not a project manager three layers up. Questions get answered on site.
Local to the North Valley
Chico and Durham roots. Local subs, local suppliers, and a reputation that lives where you do.
Straight bids
A clear scope and an honest number up front. If something changes mid-project, you hear about it before it costs anything.
Finished means finished
The last five percent is the difference between a job and a reputation. Punch lists get done, not promised.
Hire the contractor who shows up when he says, bids what he means, and finishes what he starts. That is the whole pitch.

Build it square
