Customer Reviews


Alistair Taylor, Cambs

Very prompt delivery, Replaced a rotten rose arch so the adjustment feature proved to be very helpful to fit around existing path. Well made and good value as have been other products which I have purchased from this company previously. Highly recommended


Chris Rogers, Lincolnshire

It was delivered within a few days early in the morning. The arch is well made of quality treated timber, easy to erect and looks just perfect. There was nothing of this quality in any garden centre and is incredible value for money.


Kolodziej, North Yorks

Excellent sturdy arch. Also adjustable meaning fits over the path as we want it. Good value as we had seen more expensive similar arches, but flimsy at GC's .even including the delivery charge.


DR, Lincolnshire

Quality arch, well made and easy to assemble. I have used Witham Timber many times and never been disappointed with quality and service and will continue to use them.


Bedford, Lincolnshire

Excellent product, easy to put together, very sturdy and looks very nice. Adjustable width is a bonus too as it allowed for customisation in order to fit some HD Diamond trellis either side without the need to alter anything. 👍


Raymond Dunlop, Lincolnshire

We had previously bought and erected some Omega Top Fence Panels and decided to add the arch to match. The Omega Top Arch is very sturdy and made from high quality timber with a really nice finish. The erection of the arch was straight forward and everything fitted together perfectly. Once again we were very pleased with our purchase /delivery and the excellent customer service we received from the Witham Timber staff. I would have no hesitation in recommending Witham Timber and their products, you won't be disappointed.
