Cannot fault the service or the quality of the wood. Instruction’s were clear and precise (just make sure you get your measurement spot on, before ordering!) it’s been so good will be using them again when I plan on decorating the bedroom.

I was very impressed with the attention to detail. My measurements were checked and it turned out to be an error in my part. Delivery was extremely well packaged and the exact size I needed after the sizes were amended.

Gerry H,

Ordered MDF panelling. The ordering process was easy, and the panelling was well packaged and labelled which simplified the installation greatly. Take a tip from me - don’t be a cheapskate - if you’re going to paint then buy it primed and save yourself an extra step. Highly recommended.

KENNETH MILLER,

Product is really good and delivery driver was extremely helpful
