Oak is a natural product and each beam will vary slightly in:
- Colour
- Grain pattern
- Knots
- Surface cracks
- Character markings
Our character grade beams may contain natural splits and checks which can continue to develop as the timber acclimatises.
Although air-dried, oak may continue to shrink slightly as it adjusts to your property's temperature and humidity.
If installing above a fire or log burner, we recommend gradually increasing heat exposure over the first week.
These characteristics are not faults — they are part of the beauty of real solid oak.

Very pleased with the beam. Arrived early than stated

We have just recently had a wood burner installed and needed a mantel . After searching everywhere I came accross Celtic Timber . The service I received was 5 ⭐️’s . Customer service was brilliant - I ordered the mantel on the Thursday and it was received the following Wednesday . Superbly wrapped and absolutely no damage .Literally AMAZING quality . The Mantel was lightly worked and was cut specifically to my wishes . We chose a 6x8 size (6 being width) and this was very heavy . If there is one negative , I would say that the fixings supplied were not going to be strong enough ( this was over 32kg in weight !) Not a problem for my installer as they have experience with this and came prepared with extra strong bolts , my mantel wont be moving anywhere for a LONGGG time .
Oil supplied was PURE … at first I wasn't too sure about the colour but actually its perfect . Dont be alarmed by the tiny bottle , this is more than enough for a beam this size - I still have some left over ! It applied well and really brings out the beauty of the wood .
I would use this company again and definitely recommend to others . Even my installers commented on what amazing quality and how nice the wood is.
Very pleased with the results - Thank you Celtic Timber - Exceeded my expectations, I am extremely pleased .
A
Excellent product and great value compared to many other sites. Good communication and instruction. Easy to stain and to hang on wall. Looks fabulous and exactly as hoped.
T
Needed to give the log fire some character.
Purchased this and installed it as per video and what a difference it made to the look.
It looks elegant, homely, warm especially this time of year when the log burner is on ……the wife loves it.
Definitely would recommend Celtic Timber.
N
The mantle looks fantastic. It was a little tricky to install and needed two strong people for the installation. I would say that the 12 mil drill hole was extremely tight and had to be made slightly bigger.
Either way it looks wonderful.
It was easy to oil and brought the colour of the wood alive.
R
Exactly as described, very high quality, pretty easy to finish and install too
C
Really pleased with my beam I haven't oiled it yet everyone admires it even the joiner that put it up for me
I've noticed the longer we've had it the cracks are opening up more which I love
Thank you for a lovely job
S
