Who We Are
Two Generations of Doing Things the Right Way
Gary Chagnon started this company in 1992 with a simple idea: build homes people are proud to live in. Today, he and his son Patrick run the business together — Gary handling design, Patrick running construction — and that same standard drives everything they do.
We're not the biggest builder in the valley, and that's by design. We take on projects we can give our full attention to, whether that's a whole-house renovation or a new deck you've been putting off for years.

What We Do
From the Ground Up — Or Just the Kitchen
Every home is different, and so is every project. Here's the range of work we do well.
Custom Homes
Build from scratch with our full design-build approach. One team from start to finish.
Kitchen Remodeling
New layouts, better flow, finishes that fit your style and your life.
Additions
We design and build additions that feel like they were always part of the house.
Bathrooms
Build your dream bathroom with our full design-build approach. One team from concept to completion.
Basements
Transform your basement with our full design-build approach. One team from planning to final build.
Decks & Porches
Create the perfect outdoor deck with our full design-build approach. One team from design to installation.
What We Do
A Clear Process, No Runaround
Here's how we keep things smooth from first call to final walkthrough.
01
Consultation
We sit down, listen to what you're after, and visit your property. We'll talk goals, budget, and what's realistic — no pressure, no sales pitch. This one's on us.
02
Design & Planning
Gary develops architectural plans and material selections tailored to your project. You'll see detailed drawings and a clear proposal before we break ground.
03
Construction
Patrick and our crews get to work. You'll have a dedicated point of contact, regular updates, and access to our client portal so you always know where things stand.
What Homeowners Say
Don't Take Our Word for It
★★★★★
Done business with Chagnon for a while, if I could give more than 5 stars I would. This is the contractor you wished you'd hired.
Sean
★★★★★
CBR re-did our deck. The new deck is beautiful (and so much safer for my family) but what really stood out was that they didn't seem to be trying to increase the price any chance they got. They gave us honest options throughout. I also love the project management program they use to keep us updated.

Deck Project
★★★★★
These guys are amazing! They did my front porch and it came out beautiful!! Gary and Pat work well together and their level of craftsmanship is so beautiful, there is so much attention to detail. They use quality materials and the finished product is more than I could have asked for!
