What We Do
About us
Westwood Siding has been serving homeowners across Toronto and the GTA since 1977.
Founded by Tony Sr. and now continuing as a second-generation family business, Westwood has completed thousands of siding and exterior renovation projects throughout Toronto, Scarborough, Etobicoke, Mississauga, Oakville, Burlington and surrounding communities.
Our experience covers James Hardie fibre cement, vinyl, aluminum and wood siding, along with soffit, fascia and eavestrough systems.
Every project starts with careful preparation and an understanding that the performance of siding depends just as much on what happens behind it as the material homeowners see on the finished exterior.
From replacing aging aluminum and vinyl siding to complete exterior transformations, our focus remains the same: proper installation, careful finishing and exterior work designed for Ontario weather.

Great siding starts with what you don’t see.
Proper preparation, moisture protection, flashing, fastening and spacing all play a major role in how well your siding performs over time.
Westwood Siding has been installing exterior cladding since 1977, and we know that even the best siding material can fail when the installation behind it is rushed or done incorrectly.
We assess your home, discuss material options, and provide clear, honest guidance based on your needs and the condition of your exterior.
Existing materials are handled properly, surfaces are inspected, and all necessary prep work is completed before installation begins.
Siding and exterior systems are installed with correct fastening, spacing, and attention to clean finishing details.
Every project is reviewed to ensure proper installation, clean results, and long-term performance before completion.
Westwood Siding provides professional siding installation and exterior renovation services across Toronto and the Greater Toronto Area.

I am beyond thrilled with the exceptional work done by Tony and the team at Westwood Siding on the siding project for my home! The entire experience, from start to finish, was seamless and effortless thanks to Tony’s clear communication and professionalism. Not only did the final result exceed all of my expectations, but it also garnered compliments and admiration from my neighbors, who couldn’t stop raving about how stunning the house looks. The team at Westwood Siding truly transformed my home, and I would highly recommend their services to anyone seeking a top-notch consultation, top-quality service, and breathtaking end results. Thank you, Westwood Siding, for making this a truly amazing experience.
Scarborough. The level of workmanship, attention to detail and solution solving by Tony and his team is exceptional! Based on a referral by a neighbour, the team delivered on the positive expectations set for them. As a semi-detached house, they seamlessly connected to the adjoining property. They took great care to seal all the seams of the boards, which is critical for this material. Without hesitation, I recommend their services!
The cedar shake siding of our 137 year old rowhouse was in dire need of replacement. We asked several companies to quote, and without question, Tony and Westwood won out on every aspect: Value for money, communication (Tony ALWAYS answered every call personally!!), professionalism, and quality of the finished product. I have nothing but praise for Tonys team, led by Paulo; they worked tirelessly, answered all questions, paid keen attention to detail, and when the job was complete, had the backyard pristine before they left. It was a challenging job: tight spaces, lots of debris (& no place for a bin), but they simply dealt with the challenges and powered forward. Many, many thanks, Tony, for a job well done!
