  • Our philosophy is one of focus. We focus on Lumber and building materials and we manage our quality carefully. We take pride in knowledge of our products and our ability to provide what you need, when you need it.



1836 – Roots of Perth Planing Mill begin when Alexander Kippen commences a wood working business at 44 Wilson St. West, manufacturing sash, doors and blinds, which then grows to include a planing operation.

  • Horse-drawn fleet

    1875 – Kippens Mill purchases 350,000bdft of lumber @ $14/thousand

    1916 – P.W. Clement Purchases the Company and eventually changes the name to Perth Planing Mill. Continual advancements are made to facilities and operations paving the way towards retailing.

  • Old storefront

    1947 – A partnership is formed between William Clement and R.C. McLenaghan, and the business continues to evolve, primarily into a retail operation

    1980 – Under John McLenaghan the company grows to include larger warehousing, multiple locations, and a number of industry parties and banners.

  • Our team

    Today – The current operation resides at 25 Lanark Rd. While the planer has ceased operating, the retail operations continue in a larger and more focused format. Now in its 3rd McLenaghan generation, PPM Supply offers indoor lumber storage, and exceptional deliver service, and a broad of products for those focused on the business of residential, agricultural and light commercial construction.



    We have been at your service, helping to build our local and neighbouring communities for many generations!


    In a world of box stores, we have chosen a path less travelled. We focus on the core products needed by those in the process of building and renovating.


    Our products and suppliers are chosen carefully to meet or exceed the expectations of our customers, and the vast majority of our products are stored indoors in our drive through building materials warehouse.

  • "I would like to take this time to thank the Perth Planing Mill Supply for their years of commitment and dedication to service, supplying Ennis Construction for over 30 years of business. The materials being provided are of high quality and their team at Perth Planing Mill also stand true to that, assisting you with any project. The bulk of our materials we have used over the years were framing lumber, sheathing, roofing, exterior cladding and interior finishing. Over the years we may have encountered a few issues that were quickly resolved and appreciated. I hope for many more years of business together."

  • "The Perth Planing mill has been a great source of supply for building material for us for over 30 years. Now two generations of great, fast and efficient service, competitive pricing, courteous, eager to please, well informed accommodating and qualified staff. I know of no other competitor with these attributes."

  • "When we realized that we were going to build a new home in Perth we knew that we had to do some serious researching for supplies and services. We went to different local suppliers, asked for estimates, and waited for replies. Our son, an apprenticing plumber and woodworker mentioned a hidden away supplier on Hwy 511. Our house framer also recommended this same supplier, so we went to PPM and talked to the owner about our project. Immediately we felt welcome, found very competitive pricing, quality products and one on one service. The entire staff from the order desk to the delivery folks were always helpful, respectful, friendly and courteous. One of our best experiences was sitting with the owner Luke, and working together on our windows and doors order. His experience and knowledge guided us through our entire project. Building your own home can be a daunting project, but thanks to PPM going above and beyond the normal service, we completed our home and are thrilled with the results."
