House framing under construction

General Construction

Reliable construction services for residential and commercial projects in The Ottawa Valley.

More Than Concrete

While concrete is at the core of what we do, COA also provides general construction services that complement our concrete work. From framing and structural builds to finishing and repairs, we bring the same professionalism and reliability to every job.

If you're looking for a dependable crew to handle construction work alongside your concrete project — or as a standalone job — we're ready to help.

What We Offer

  • Residential construction and builds
  • Commercial construction projects
  • Structural framing
  • Garage and shop builds
  • Additions and renovations
  • Project coordination with trades

One Team, Fewer Headaches

Working with COA means fewer contractors to coordinate. When your project needs both concrete and construction work, we manage the full scope — reducing delays, miscommunication, and finger-pointing between trades.

Our Process

1

Consultation & Planning

We meet with you to understand the project, review plans or help develop them, and discuss timelines, budget, and any specific requirements.

2

Permits & Scheduling

We assist with building permit applications, schedule trades, order materials, and set a realistic construction timeline for your project.

3

Construction

Our crew handles the build with consistent communication throughout. We manage the day-to-day work, coordinate any sub-trades, and keep the project on schedule.

4

Walkthrough & Handoff

We do a final walkthrough with you to confirm everything meets your expectations. Any punch-list items are addressed before we consider the job complete.

What Affects the Cost

Construction project costs depend on the scope, complexity, and materials involved. A basic garage build is a very different job from a custom home addition or a commercial building. We break down every quote by phase so you can see exactly where your money is going.

Material costs fluctuate with the market — lumber, steel, and concrete prices can shift seasonally. We provide quotes based on current pricing and lock in material costs as early as possible to avoid surprises. Labour requirements, permit fees, and any specialty trades needed for your project are all included in our estimates.

We offer free consultations and detailed quotes for all construction projects. Whether you have full blueprints or just an idea, we will help you understand what is involved and what it will cost before you commit to anything.
