Built on Craft, Driven by Family

We started with a pickup truck and a love for building. Two decades later, we are still a family operation -- just with better tools.

From Father & Son to Full Crew

Timberline Deck Co. started in 2003 when Mike Callahan and his father, Tom, decided to turn their weekend carpentry projects into a real business. They had been building decks for neighbors and friends for years -- it was the work they loved most, and people kept asking for more.

What began as a two-man operation working out of a single truck has grown into a company with a dedicated design team, a full construction crew, and a shop where we can fabricate custom components. But the foundation has never changed: do honest work, use the best materials, and treat every homeowner's backyard like it is your own.

Today, Timberline is still family-owned and operated. Mike runs the business, his daughter Sarah handles design, and the crew includes builders who have been with us for over a decade. We are not interested in becoming the biggest deck builder in the state. We are interested in being the best one.


The People Behind the Builds

Small team, big experience. Every person at Timberline is here because they love the craft.

Mike Callahan

Owner / Master Carpenter

Mike has been building decks for over 25 years. He learned the trade from his father, earned his contractor's license in 2003, and has personally overseen every project Timberline has completed. If there is a tricky structural problem, Mike is the one solving it.

Sarah Callahan

Lead Designer

Sarah joined the family business after studying architecture. She brings a modern design sensibility and is the one who creates the 3D renderings that help homeowners visualize their new outdoor space before a single nail is driven.

Dave Ruiz

Project Manager

Dave keeps every project on schedule and on budget. He coordinates permits, material deliveries, inspections, and crew assignments. He has been with Timberline for 12 years and knows the ins and outs of every municipality in our service area.

Every Build Is Different

We do not believe in one-size-fits-all decks. Every project starts fresh because every home, yard, and family is different.

Custom Design for Every Home

We study how your home sits on the lot, where the sun hits throughout the day, how you plan to use the space, and what views you want to highlight. The deck is designed around all of it.

Working with the Landscape

Slopes, trees, drainage patterns -- we work with your yard, not against it. We incorporate natural features rather than bulldozing them, which results in a more natural, integrated feel.

Built for How You Live

A family with young kids needs a different deck than a couple who loves hosting dinner parties. We design around your actual life, not a generic template.

Overbuilt, Not Under-Engineered

Our framing exceeds code requirements. We use larger joists, closer spacing, and more fasteners than required. The result is a deck that feels rock solid underfoot for decades.

What We Build With

We work with the best decking materials available. Here is an honest breakdown of each option.

Pressure-Treated Lumber

$ -- Most Affordable

The workhorse of deck building. Treated pine is durable, strong, and budget-friendly. Requires regular sealing and staining to maintain appearance and prevent weathering.

  • Lifespan: 15-20 years with maintenance
  • Maintenance: Seal/stain every 2-3 years
  • Best for: Budget-conscious projects
  • Can be painted or stained any color

Western Red Cedar

$$ -- Mid-Range

Naturally rot-resistant with a beautiful warm tone and aromatic scent. Cedar is a classic choice that weathers gracefully and offers natural insect resistance without chemical treatment.

  • Lifespan: 20-25 years with maintenance
  • Maintenance: Oil or stain every 1-2 years
  • Best for: Natural beauty lovers
  • Naturally resistant to rot and insects

Trex Composite

$$$ -- Premium

Made from recycled wood fibers and plastic, Trex composite delivers the look of real wood with virtually no maintenance. As a Trex Pro Platinum installer, we guarantee expert installation.

  • Lifespan: 25-30+ years
  • Maintenance: Occasional soap and water
  • Best for: Low-maintenance lifestyle
  • 25-year fade and stain warranty

Ipe Hardwood

$$$$ -- Ultra-Premium

The hardest, most durable decking material available. Ipe is a tropical hardwood that is naturally resistant to everything: rot, insects, fire, and scratches. It ages to a silver patina or can be oiled annually.

  • Lifespan: 40-75+ years
  • Maintenance: Annual oiling (optional)
  • Best for: Luxury, long-term investment
  • Class A fire rating
