Care & maintenance
Caring for your oak building
Oak is one of the most low-maintenance building materials there is, here's how to keep it looking its best for a century and more.
How oak ages
The first three years of your frame
Green oak isn't finished when it's raised, it's just beginning its life. Here's what to expect as it seasons in place.
0-6 months
Fresh and green
Your frame has just been raised. The oak is pale, joints are tight, and the timber is at its highest moisture content. No treatment needed, let it settle.
6-18 months
First checks appear
Surface checks and shakes begin as the oak dries. This is completely normal, the grain opens slightly and the joints tighten further. Resist the urge to treat or oil.
1-3 years
Silvering begins
Exposed oak starts to weather from honey-gold to soft silver-grey. Indoors, it deepens to amber. The frame is now structurally tighter than the day it was raised.
3+ years
Settled and stable
Moisture content has equalised. Movement slows to a near stop. Your oak building now looks established and mature, and will for decades.
The golden rule
Keep the roof sound, leave the oak alone
An oak frame wants one thing above all: a sound roof that keeps water off the joints. Do that, and the timber looks after itself.
Do
- • Keep the roof sound, a leaking roof is the only real threat to an oak frame
- • Clear gutters and downpipes each autumn to prevent water tracking onto the frame
- • Wash the frame annually with a soft brush and fresh water
- • Trim vegetation back to allow airflow around the timber
- • Inspect pegs and joints visually once a year
- • Let exterior oak weather naturally to silver-grey
Don't
- • Don't pressure-wash the oak, it drives water into the grain and erodes the surface
- • Don't use chemical cleaners, bleach or wire brushes
- • Don't paint or varnish exterior green oak, it traps moisture and causes rot
- • Don't fill surface checks, they move seasonally and the filler will fall out
- • Don't panic at cracks, they're a sign of healthy drying, not damage
- • Don't let Ivy or climbing plants grow directly on the frame
If you want to treat it
To oil or not to oil?
Most oak is left untreated. If you prefer to keep the fresh-sawn colour, here's what to know.
Exterior oak
Leave it to silver, it's the authentic heritage look and needs zero upkeep. A breathable exterior oil can slow silvering, but requires reapplication every 1-2 years.
Interior oak
A natural wax or breathable oil enhances the grain and deepens the amber tone. Apply one coat and refresh occasionally, far less maintenance than paint.
Joints & pegs
Never seal or treat joints, let them breathe. Pegs are designed to be visible; if one works loose over time, contact us rather than driving it back yourself.
