The only ISO 9001-certified timber structure repair firm on earth
The case for timber
When it's built right, wood outlasts
Lighter, longer-lived, lower-carbon, and more cost-effective than the steel or concrete alternative, when the workmanship is right. A concrete bridge lasts 50–70 years; a properly built and maintained timber bridge lasts far longer. The problem was never the material. It was the workmanship, and the reputation poor methods gave a material that never earned it.
Our proprietary treatments, patented reinforcement, and ISO 9001-certified process unlock the material’s full lifespan. We exist to change that standard, permanently.
"When built and maintained properly, a timber bridge easily lasts over a century."

Why timber
Lighter, longer-lived, lower-carbon, and more cost-effective
The reputation timber earned came from poor workmanship, not the material. Built to our standard, it outperforms steel and concrete on the things that actually decide a project.
Costs less
More cost-effective than a comparable steel or concrete structure: in materials, in the lighter foundations it allows, and in field time.
Outlasts the alternatives
Concrete manages 50–70 years. Built and maintained right, timber serves 100+: one build instead of two.
A fraction of the weight
Light enough to reuse existing piles and foundations, as on the Roger Bacon Bridge. Impossible with the mass of steel or concrete.
Stores carbon
The only structural material that grows, storing carbon for the life of the structure, a fraction of the embodied emissions of steel or concrete.
Strength that holds up
Meets modern loads while resisting the corrosion that attacks steel and the cracking and spalling that age concrete, especially in coastal and embedded zones.

The TRS difference
Engineering rigor you can verify
We don’t ask you to take longevity on faith. The proof is in the certification, the patents, and the fact that every structure is built and load-tested before it ever reaches your site.
ISO 9001-certified
The only timber structure repair firm on earth to hold it.
40+ patents
Proprietary reinforcement IP, not borrowed technology.
Full in-shop assembly
Built and load-tested before treatment or shipping.

Their commitment to safety, quality and the environment was best practice, the field crew hard-working, polite, and appropriately skilled. Both Council and the community are very pleased with the finished project, and I have no hesitation in recommending Timber Restoration Services on future projects

Sustainability
The most sustainable choice is the one that lasts
Timber is the only major construction material that grows. It sequesters carbon while it lives, produces a fraction of the emissions of concrete or steel, and, built to our standard, lasts for generations without replacement.
We source responsibly, salvage and recycle timber from every project, and never tear down a structure within a human lifetime.
100+ years
Design life of a properly built and maintained timber structure.
Carbon-storing
Every span we build keeps sequestered carbon locked in place for its lifetime.
