Timber Frame Repairs

Timber frame corner post repairs with the brace reinstalled.

Historic timber-framed buildings require specialist knowledge, sympathetic repair methods and an understanding of traditional construction techniques. Harber Carpentry and Restoration undertakes traditional timber frame repairs for listed and historic buildings across East Anglia.

We repair and conserve structural timber frames using traditional carpentry methods, breathable materials and conservation-led approaches designed to preserve the character and integrity of historic buildings.

Specialist Timber Frame Repair for Historic Buildings

Timber-framed buildings behave differently from modern construction and often require careful diagnosis before repairs begin. Moisture ingress, failed roofing, trapped damp and inappropriate modern materials can all contribute to timber decay over time.

Our work includes:

Oak beam repairs
Sole plate replacement
Timber frame conservation
Structural timber repairs
Scarf joint repairs
Timber splicing
Traditional oak framing
Listed building timber repairs
Historic barn repairs
Timber frame stabilisation

We aim to retain as much original material as possible while ensuring the long-term stability of the structure.

Traditional Green Oak Framing & Carpentry

Honouring heritage through authentic, hand-crafted timber work.

We specialise in traditional timber framing and structural restorations, working exclusively with English green oak to preserve, repair, and recreate historic timber structures. Staying completely true to the methods of master carpenters of the past, all of our oak is meticulously hand-planed prior to fitting. This ensures that every beam retains authentic tool markings and a distinct, historic texture that modern, machine-sawn timber simply cannot replicate.

As green oak naturally seasons and cures over time, it develops the classic silver-grey patina and subtle structural twists that give period architecture its timeless strength and character.

Traditional Framing & Repairs: Constructing new timber frames or undertaking sympathetic structural restorations using time-honoured joinery.
Hand-Planed Finishes: Meticulously hand-tooling every surface before installation to ensure an authentic, historically accurate aesthetic.
Sympathetic Timber Interventions: Executing precise repairs, from traditional scarfed joints to structural beam replacements, ensuring structural integrity without losing character.

Common Causes of Timber Frame Decay

Historic timber frames are often affected by moisture-related deterioration. Problems commonly occur where modern materials have restricted the building’s ability to breathe naturally.

Common causes include:

Cement render trapping moisture
Failed lime mortar joints
Poor drainage
Roof leaks including guttering
Inadequate ventilation
Ground moisture affecting sole plates
Insect or fungal attack
Structural movement over time

Understanding the source of decay is essential before repairs are undertaken.

Frequently Asked Questions

What causes timber frame decay?

Timber frame decay is commonly caused by prolonged moisture exposure, poor ventilation, trapped damp and inappropriate modern materials that prevent historic buildings from breathing naturally.

Can rotten oak beams be repaired?

Yes. Traditional scarf repairs and timber splicing methods can often preserve historic oak beams without requiring full replacement.

Do listed building repairs require consent?

Some structural repairs to listed buildings may require listed building consent depending on the scope of work and materials involved.

What are scarf joint repairs?

A scarf joint repair involves removing decayed timber sections and carefully joining new timber into the existing structural member using traditional carpentry techniques.
