What's included

Built from the ground up.

A deck is only as good as what holds it up and how it meets the house. We get both right, then make it look good.

  • Layout and design planning
  • Building permits, where your project needs them
  • Footings and structural framing
  • Decking, stairs and landings
  • Railings
  • Roof structures for covered patios
  • Flashing and weatherproofing where it meets the house
  • Lighting and fan wiring, through licensed trades
  • Final walkthrough and clean-up

From our job sites

Built to sit in the weather.

Outdoor structures in the Fraser Valley spend months in the rain. The same attention to framing, fastening and drainage goes into every deck, patio and dock we build.

How we work

Six steps, no surprises.

Every project follows the same path, whether it's a bathroom or a basement suite. You always know what happens next.

  1. Consultation

    A conversation about what you want to change, how you use the space and when you'd like it done.

  2. Free on-site estimate

    We visit your home, measure, and look closely at the existing conditions. There's no charge for the estimate.

  3. Detailed proposal

    A written proposal covering scope and materials, walked through with you line by line.

  4. Scheduling

    We set your start date and plan the work around your household.

  5. Build

    Denis runs the site. You get regular updates as the work moves along.

  6. Final walkthrough

    We walk the finished work with you and make sure every detail is right before we call it done.

Great company! I needed an awning installed on the side of my mobile home to eliminate moisture and water from leaking through my doors and windows. They worked hard to ensure that everything was sealed and weatherproofed on-top of installing the awning. Great work and fair prices, I will use them again for any custom work or upgrades needed on my place. Thanks again!

As a professional working with clients who expect the best, finding a reliable carpenter is crucial, and Denis exceeded every expectation. He recently completed a project for my clients, and the results were nothing short of amazing. Here is why I'll be hiring him again:

  • Top-Tier Quality: His attention to detail and craftsmanship are evident in every joint and finish.
  • Professionalism: He was a pleasure to work with—communicative, respectful of the property, and incredibly easy to coordinate with.
  • Reliability: He stayed exactly on budget and was remarkably timely, hitting every milestone we discussed.

If you are looking for a skilled carpenter who brings both integrity and talent to the job site, look no further. Thank you, Denis, for making me look good to my clients!
