About Exterior Pro Materials
Canada's Trade Source for Exterior Building Materials
We started Exterior Pro Materials because contractors in Ontario kept running into the same wall: two or three distributors, limited colour depth, and quotes that took longer than the project timeline. That's a real problem when you're coordinating a re-side on a 40-unit subdivision or trying to match existing fascia on a heritage renovation. We built something different - a focused catalogue of exterior cladding, trim, ventilation, and building envelope products from the manufacturers Canadian contractors actually specify, priced for trade volume.
Today we supply 137 products across 25 categories - vinyl siding, cedar shake and stone veneer, engineered wood and fiber cement, metal cladding, soffit and fascia, eavestroughs, PVC trim, windows, housewrap, landscaping and paving systems, and installation tools. Every product is tested and specified for Canadian climates, not rebranded imports that haven't been evaluated against freeze-thaw cycles, heavy snow loads, or the coastal humidity of BC.
Whether you need a single-house colour match or subdivision volume for 200 units, the process is the same: submit your material list, get a quote, and we'll confirm availability and lead time. No minimums on most lines, no sales pitch - just accurate pricing and product that ships.

Structured for contractors buying at job-site volume - no membership fees, no minimums to unlock better rates. Consistent trade pricing from the very first quote.
Curated, Not Comprehensive
137 products across 25 focused categories. Every product evaluated for Canadian climate performance, manufacturer support, and contractor serviceability.
Colour Depth That Delivers
Mitten and Kaycan lines carry 20–40 colours per siding profile, with matched soffit, fascia, and trim - stocked year-round, no factory delays on standard specs.
Quote in Hours, Not Days
Submit your cut sheet and get a same-business-day quote with stock confirmed. Book your crew on an accurate timeline - not a moving target.
Manufacturer Partners
Brands Canadian Contractors Specify
Every brand in our catalogue is an authorized supply relationship - real manufacturer support, no grey-market product.
FAQ
Common Questions from Contractors
Straight answers to what contractors ask us most before placing their first order.
Still have questions? Get in touchDo you supply to homeowners or only to trade professionals?
Primarily trade - contractors, builders, renovation companies, and building supply businesses. That's who our pricing and quoting process is built for. If you're a homeowner working on your own property, we're happy to discuss your project, but most of what we do is wholesale supply to professionals working at job-site volume.
What areas of Canada does Exterior Pro Materials serve?
Our primary supply footprint is Ontario and Western Canada. We ship to contractors across the Greater Toronto Area, Hamilton, Ottawa, and throughout Ontario, as well as BC, Alberta, and Saskatchewan. If you're outside those areas, contact us - depending on the product and volume, we may be able to accommodate.
How do I get a price on materials for a project?
The easiest way is to use the Quote Request form on our website - list your products, quantities, and colour preferences, and we'll come back with pricing and availability within the same business day on most requests. If you have a cut sheet or takeoff in Excel or PDF, you can attach it directly. No account required.
What's the minimum order to buy from Exterior Pro Materials?
There's no formal minimum on most product lines. Practically speaking, we're most useful to contractors ordering at job-site quantities - full boxes of siding, full coils of trim, cases of accessories. We don't stock individual panels, but we're not going to turn away a smaller order if we have the stock and the margin works.
Do you carry ENERGY STAR certified products?
Yes. Our window lines are ENERGY STAR certified for Canadian climate zones, and our housewrap and building envelope products meet or exceed the thermal performance requirements of the National Building Code and provincial energy codes including OBC SB-12 and BC Energy Step Code.
What's the difference between Mitten and Kaycan vinyl siding?
Both are excellent Canadian manufacturers with strong warranty programs. Mitten is known for particularly deep colour palettes and high-impact formulations - the stronger choice when colour selection depth matters. Kaycan has a broader portfolio and is especially strong in PVC trim and eavestrough accessories, making them easier to spec as a complete exterior package. We carry both.
Can I get samples before ordering?
For siding, yes - we can provide colour chip samples for Mitten and Kaycan lines so you or your client can make a colour decision before committing. For larger samples (a full shake panel, a stone veneer section), we handle those case-by-case. Contact us and we'll confirm what's available.
Do your products come with manufacturer warranties?
Yes. Mitten's premium vinyl siding carries a Limited Lifetime warranty. Kaycan lines carry 25–40 year warranties depending on the product. CertainTeed Restoration Millwork carries a 25-year limited warranty. Imperial aluminum railings carry a 20-year warranty. Everything ships with full manufacturer support - no grey-market product, no discontinued inventory.
