Timber Restoration Services
We survey, repair, reinforce, and, only where we must, replace heavy timber structures and bridges, extending service life by decades while keeping as much original material as the structure safely allows.
Every restoration starts with the structure, not the surface. We map the load paths, find the hidden decay, and engineer a repair that keeps the original timber doing its job, because a structure that’s survived a century is worth far more standing than torn down.
When a member truly can’t be saved, we replace it in kind, species-matched, joined the way it was originally built, and engineered to a 100+ year design life. The result is sound, authentic, and documented to ISO 9001 standards.

Design life engineered into every restored and replaced member.
Load-path analysis, moisture mapping, and decay detection testing produce a board-by-board condition report — so the plan is built on what the structure can actually carry, not guesswork.
We strengthen the timber that's already there — Dutchman's patch repairs, pile posting, Structurfill® and Retrobond® epoxy injection, and FiRP® reinforcement (the Retroshear®, Retroten®, and Retrocom® panels) that restore full capacity in place. Decayed sections are amputated or densified and the exposed end grain sealed against moisture wicking, with preservatives applied on site — keeping the original material and the structure's character.
When a member is past saving, we replace it in kind — species-matched timber, original joinery, and heritage finish — fabricated and pre-fit in our shop, engineered to a 100+ year life.
We document the structure as built, geometry, connections, and a board-by-board record of its current condition.
Decay detection testing and load-path analysis reveal what’s sound, what’s failing, and exactly what each member can carry.
We repair and reinforce in place, and shop-fabricate any in-kind replacements, load-tested before they reach your site.
We arrest active decay with Decaystop®, a borate solid-rod preservative that activates as moisture rises above decay levels, and borate diffusion treatment in the zones decay detection testing flagged, then apply heritage-matched finish, and hand over documentation reviewers can sign off on.
Our offices sit in three countries, but our restoration work doesn’t stop at their borders. We’ve surveyed, repaired, and reinforced 500+ heavy timber structures, with reach across 55 countries and six continents.
Crews travel to the structure, and shop-built replacement members ship worldwide. Tell us where your project is and we’ll tell you honestly what’s feasible.
Far more often than people expect, it can be restored. Our assessment — load-path analysis plus decay detection testing — tells us what’s truly sound beneath the surface. We replace only the members that are genuinely past saving, and we tell you honestly which those are.
That’s the entire point. We keep as much original material as the structure safely allows — typically the large majority of it — and any replacement is in kind: species-matched, joined the way it was originally built, and finished to match.
Yes. Our in-place repair approach is built to satisfy historic-review requirements for material authenticity, and everything is documented through our ISO 9001 process so reviewers have an auditable record.
We engineer every restored and replaced member to a 100+ year design life. A timber structure restored and maintained to our standard outlasts the concrete and steel alternatives that would have replaced it.
Any in-kind replacement components are fabricated and pre-fit in our climate-controlled facility and load-tested before shipping — so on-site work is faster, lower-risk, and disrupts your structure for less time.
