Serving Waterloo's University-Area Rentals And Established Residential
Waterloo blends established residential neighbourhoods — like Beechwood and Columbia Hills — with newer development north of Weber Street and a significant rental property stock near the university corridor.

About Our Siding Installation & Repair Service in Waterloo
New siding is one of the most impactful exterior upgrades an Ontario homeowner can make — improving insulation, curb appeal, and weather protection in a single project. D&D Exterior Finishing installs vinyl, aluminum, and fiber cement siding on homes of all sizes and ages. Every installation includes proper moisture barrier, flashing, and trim work — the details that separate a lasting siding job from one that fails within a decade.
Ontario Building Code & Climate Context: Ontario Building Code Section 9.27 governs exterior cladding installation, requiring proper weather-resistant barriers behind cladding and adequate drainage planes to prevent moisture accumulation in wall assemblies. Improper siding installation — particularly missing or lapped house wrap, incorrect flashing at windows, and unsealed penetrations — is one of the leading causes of premature rot in Ontario homes. D&D Exterior Finishing installs complete weather barrier systems, not just siding panels.

Frequently Asked Questions — Siding Installation & Repair in Waterloo
What is the best siding for Ontario's climate?
Vinyl siding with foam insulation backing is one of the most popular choices for Ontario — combining good thermal performance, durability through freeze-thaw, and low maintenance. Fiber cement (HardiePlank) offers premium durability and a wood-like appearance.
How long does siding installation take?
A typical residential siding project takes 3–7 days depending on house size and complexity. We provide a detailed schedule with your estimate.
Do I need a permit for new siding?
Like-for-like siding replacement typically does not require a permit in Ontario. If you're adding insulation boards that change the wall assembly, a permit may be required. We advise during your estimate.
Can you install siding over existing siding?
Installing over existing siding is sometimes done but is generally not recommended. It prevents proper inspection of the moisture barrier, can create a drainage problem, and may void material warranties. We typically recommend removal for a proper installation.
What warranty comes with new siding?
Siding products from CertainTeed, Ply Gem, and Canexel typically carry 25-year to lifetime manufacturer warranties against manufacturing defects. D&D Exterior Finishing provides a 5-year workmanship warranty on all siding installations.
