Supply & install from Gentek, Mitten & Kaycan — Family-owned, 30+ years
Ontario’s Most Popular Vinyl Siding Choice
At A-1 Siding & Windows Niagara, vinyl siding is our most requested exterior product for homeowners across the Niagara Region and Hamilton area. We’ve been installing vinyl siding for over 30 years. From St. Catharines and Niagara Falls to Stoney Creek, Hamilton, and Ancaster, we help homeowners choose the right product and install it properly the first time.
We supply and install vinyl siding from three of Ontario’s most trusted manufacturers — Gentek, Mitten, and Kaycan. Whether you’re replacing old, worn siding on a home in Welland or upgrading a newer build in Grimsby, we’ll match the right profile and colour to your home and budget.
Vinyl Siding Profiles We Install
Choosing the right profile makes a big difference to your home’s finished look. Here’s a breakdown of the most popular options we install across the Niagara Region and Hamilton area.
Horizontal Lap Siding
The most popular profile in Ontario. Horizontal panels run across the wall in overlapping rows, shedding water effectively and giving homes a clean, classic look. Available in Double 4″, Double 5″, and Dutch Lap profiles. Double 5″ is the standard for most homes in the Niagara Region and Hamilton area — it strikes the right balance between coverage and visual proportion. Dutch Lap adds a subtle shadow line for a more traditional appearance.
Board & Batten
Board and batten is a vertical siding profile that alternates wide panels (boards) with narrow strips (battens) running up and down the wall. It gives homes a bold, contemporary look and works particularly well as an accent on gable ends, garage faces, or combined with horizontal siding on the main walls. Increasingly popular on newer builds and renovations across Hamilton and Niagara. Adds strong visual height and character to any home exterior.
Beaded & Other Profiles
Beaded siding features a rounded groove along the bottom edge of each panel, adding a decorative detail inspired by traditional wood siding. It’s a refined look well-suited to heritage homes and classic neighbourhood streetscapes common throughout older areas of Niagara and Hamilton. We also install vertical panels and specialty profiles where required — ask us about what’s available from Gentek, Mitten, and Kaycan for your specific project.

Why Vinyl Siding Is Right for Ontario Homes
Ontario’s climate puts real demands on home exteriors. The freeze-thaw cycles, heavy snow, wind, and summer heat that homeowners in Niagara and Hamilton deal with every year require a material that can handle constant thermal movement without cracking, warping, or deteriorating. Vinyl is engineered for exactly this.
- Never needs painting — colour goes all the way through the material
- Won’t rot, rust, or corrode
- Lightweight — faster installation means lower labour costs
- Insulated options available for improved energy efficiency
- Excellent value for money compared to other siding materials
- Wide colour and profile selection from Gentek, Mitten, and Kaycan

Frequently Asked Questions
How long does vinyl siding last in Ontario?
Quality vinyl siding installed properly typically lasts 20–40 years in Ontario’s climate. The key is correct fastening technique — panels need room to expand and contract through the freeze-thaw cycles common throughout Niagara and Hamilton. Improper installation leads to buckling and cracking within a few years.
What’s the difference between horizontal and board and batten siding?
Horizontal lap siding runs across the wall in overlapping rows and is the most common choice across the Niagara Region and Hamilton area — it suits almost any home style and sheds water extremely well. Board and batten is a vertical profile that alternates wide boards with narrow strips, giving a more contemporary or farmhouse look. Many homeowners combine both — horizontal on the main walls and board and batten on gable ends or as an accent feature.
Does vinyl siding need to be painted?
No — vinyl siding never needs to be painted. The colour is manufactured into the material. Modern products from Gentek, Mitten, and Kaycan have significantly improved UV resistance and colour retention compared to older generations of vinyl.
Can vinyl siding be installed over existing siding?
In some cases yes, but we generally recommend removing existing siding first. This lets us inspect the sheathing underneath for moisture damage or rot — a common issue on older homes throughout Niagara and Hamilton that’s far cheaper to fix before new siding goes on than after.
What colours and profiles are available?
Between Gentek, Mitten, and Kaycan we have access to dozens of colours and profiles including Double 4″, Double 5″, Dutch Lap, Beaded, Board & Batten, and vertical siding. We can bring samples to your estimate so you can see the options against your home’s existing trim and roof colour — whether you’re in St. Catharines, Hamilton, or anywhere in between.
