Words will not do justice to the five-star service and products from the people at Perth Decking. Ross was more than helpful on advice on the flooring that I got and was able to ensure that it was delivered to the warehouse 4 days after my purchase to help me out. The flooring itself was a wonderful product, looks great and was fantastic to install. Ross also allowed me to return unopened boxes. The forklift driver was able to deftly manoeuvre the pallet onto the back of my ute so that I didn't have to load it manually and checked my weight to ensure that I had not been overloaded. Finally, when I returned home and unloaded, I noticed that my tarp bar was missing and the other salesman walked around the carpark, found it and had it waiting for me in the office when I returned. My neighbours were so impressed by the product when installed that they will be heading to Perth Decking for their requirements. Well done to all.

I recently contacted Decking Perth to purchase merbau decking. Ross was extremely helpful and knowledgeable. He gave me very good advice, completed my purchase and arranged delivery on the day I requested.The delivery driver was friendly and efficient, notified us of his arrival time on delivery day and placed the timber in a very convenient location as arranged.The merbau we received was of a beautiful quality, arriving in long straight lengths and easy to lay.I highly recommend Decking Perth to anyone requiring decking. The service we received was faultless and the quality of the product was excellent. We will definitely purchase our future decking requirements from Decking Perth.

Maureen Mandy

Decking Perth were good to deal with but because they sub let the actual installation of the decking to various carpenter tradies, you need to check with them that the installer trade price is reasonable as per Perth decking quote indication.

Very professional and most excellent workmanship from David O’Brien at CCI carpentry. First class tradesman. Many thanks to Decking Perth and the team.

Many thanks to the team at decking Perth specifically Phil for all their advice and info on moisture shield decking. The quality of the product is very good. I’ve included some basic photographs of my finished product and then a photograph of the 3 1/2 year-old new tech wood decking that I replaced. This was very poor quality. Thanks again I will use decking Perth anytime I require any form of decking. Rgds bill

The installation team were top notch and very professional, but the supply people at the warehouse said stock was there, then not, so we chose another board, then it turned out they did have stock. Overall a good experience.

Blake De Costa

The guys at Decking Perth were fabulous to deal with. Being a DYI project and never having built a deck before I had many questions which they were happy to answer. Their choice of products was extensive and we ended up choosing the Moisture Shield range. The product was great to work with and the result was fantastic. Decking Perth helped with all the ordering and delivery and happily accepted any returned unused items that were not required.Fantastic experience all round and we love our new deck.Thanks guys.

After visiting several decking businesses, I landed here to find excellent service, listening skills and advice. After choosing the material, they provided several quality different people to quote the job........(how much time did that save!) and as a result I have a lovely front and back deck. so pleased.

Charles Sullivan

Adrian at Decking Perth was very knowledgable and helpful and provided sound advice about suitable materials and finishes for my courtyard decking project for which I was very grateful. A big thanks also to Blake (contractor referred by Adrian) who did such a wonderful job translating my ideas into reality (including the bench seating) and whose workmanship was excellent. I am so happy with the finished Jarrah deck, which looks better than I could have hoped, and with my experience dealing with Adrian and Blake. Thanks so much guys!

We contacted Decking Perth via a website contact form and received a call back within an hour! We visited the showroom on a Saturday, took colour samples home and were contacted by two carpenters on the following Monday morning. Both were prompt and very reasonably priced. Our decking was completed within a day and all offcuts and rubbish removed.We are thrilled with the results.The process was quick, efficient, friendly and well priced.Thank you. :)

The level of service, quality of the timber and professionalism of the Decking Perth Team is without question the Best in the West! I placed my first order last month for some subframe H3 which arrived superfast, was well wrapped and of excellent quality. This week I have taken delivery of some additional subframe H3 and Merbau 5.7 FJ decking and was not let down. The only place I will order my decking supplies in future.
