Choosing the right siding company is one of the most important decisions you will make as a homeowner in Southwestern Ontario. The exterior of your home is not just cosmetic — it is your first line of defence against the region’s punishing weather: freeze-thaw cycles that can crack and buckle inferior materials, humid summers that invite moisture infiltration, and ice storms that test every seam and fastener. A skilled contractor using quality products can add decades of life to your home’s exterior. The wrong one can leave you with costly callbacks and voided warranties.
Whether you live in a post-war bungalow in Old East Village, a colonial revival in Byron, or a newer two-storey in Masonville, here are seven things to look for when evaluating siding companies in London, Ontario — and across the broader Southwestern Ontario region.
1. Check Reputation and Online Reviews
Word of mouth still carries weight in this industry, but today it lives online. Before you call anyone, search for the company on Google and look at their reviews — not just the star rating, but the substance of what customers are saying. Are reviewers commenting on the crew’s professionalism, the quality of the finished product, and how problems were handled? A pattern of positive, detailed reviews is far more telling than a handful of generic five-star ratings.
Also look for a company’s presence in your specific community. A contractor that regularly works in London, Brantford, or Woodstock will understand regional requirements, common home styles, and the specific weatherproofing challenges of the area. Ask neighbours who have recently had siding done — a well-regarded contractor’s trucks will show up on your street before long.
2. Verify Insurance and WSIB Coverage
This is non-negotiable. Any reputable siding company working in Ontario must carry general liability insurance and be registered with the Workplace Safety and Insurance Board (WSIB). Liability insurance protects your property if something goes wrong during the installation. WSIB coverage protects you from financial exposure if a worker is injured on your property.
Do not take a contractor’s word for it. Ask for certificates of insurance and a WSIB clearance certificate before signing anything. Both documents should be current and cover the full scope of work. Unlicensed or under-insured contractors may offer lower quotes, but the financial risk they expose you to is simply not worth it. This is a standard expectation across the industry and any professional company will supply these documents without hesitation.
3. Look for Genuine Experience
Siding installation looks straightforward from the curb, but the details matter enormously: proper flashing around windows and doors, correct overlap, adequate ventilation clearances, and precise corner and trim work all require years of practice to get right. In Southern Ontario, where homes run the gamut from century-old wood-framed houses to modern prefab builds, an experienced contractor has encountered the full range of challenges — and knows how to solve them.
Ask how long the company has been operating and how many projects they complete each year. A company with decades of experience and a consistent crew, not just a rotating cast of subcontractors, is far more likely to deliver reliable results. Read about the benefits of professional siding installation to understand why experience and technique make such a measurable difference to long-term performance.
4. Understand What Siding Materials They Offer
Not all siding is created equal, and the right material for your home depends on your budget, your home’s architecture, and your priorities around maintenance and energy efficiency. A quality siding company should be able to walk you through the options honestly, not just push whatever product gives them the highest margin.
In Southwestern Ontario, the most common options are vinyl siding and aluminum siding. Vinyl is cost-effective, low-maintenance, and comes in a vast range of profiles and colours. There are also specialty profiles worth knowing about: Dutch Lap and Board and Batten give traditional homes a distinctive character, while insulated vinyl siding adds a meaningful boost to thermal performance, which is an increasingly important consideration given rising energy costs. For a thorough comparison, our guide on aluminum siding versus vinyl siding breaks down the differences in depth.
Make sure the company you choose offers a genuine selection of siding materials and profiles, and that they are working with reputable, warranted products — ideally Canadian-made, which are engineered for our specific climate.
5. Ask About Full Exterior Services
Siding rarely exists in isolation. When a home’s exterior is being redone, it is almost always the right time to assess the eavestroughs, soffit, and fascia as well. These components work together as a system: siding channels water away from the walls, while properly functioning eavestroughs and downspouts carry that water safely away from the foundation. Damaged soffit can allow moisture and pests into the attic space, undoing the benefits of new siding within a few seasons.
A company that offers complete exterior services under one roof is a significant advantage. It means a single point of accountability, coordinated scheduling, and usually better value than hiring three separate contractors. If your home also needs roofing attention, ask whether the company handles that as well — bundling projects can reduce both cost and disruption. Learn more about how eavestroughs and exterior trim work together with your siding to protect your home’s structure.
6. Insist on a Free Written Estimate
Any professional siding company will provide a free, no-obligation estimate, and it should be in writing. A verbal quote is nearly impossible to hold a contractor to once the job is underway. A written estimate should itemize materials, labour, and any disposal or preparation costs. It should also specify the product being used, including manufacturer and profile, so you can compare quotes on an apples-to-apples basis.
When gathering estimates, be cautious of pricing that seems unusually low. Below-market quotes often signal inferior materials, unlicensed labour, or a contractor planning to cut corners on preparation work. Equally, an inflated quote does not guarantee quality. The goal is fair pricing for clearly defined, high-quality work from a company with a verifiable track record in the area, whether that is Kitchener, Norfolk County, or anywhere in between.
7. Pay Attention to Customer Service from the First Call
How a company treats you before they have your business tells you a great deal about how they will treat you after. Does someone answer the phone promptly? Do they follow up when they say they will? Are they transparent about timelines, materials, and what happens if something unexpected comes up mid-project?
Good customer service in the trades is not about salesmanship, it is about clear and consistent communication throughout the entire project. The best siding contractors will walk you through their process, explain what to expect on installation day, and leave your property cleaner than they found it. Ask for references from recent projects and actually call them. A company confident in its work will encourage it. Your home is your most valuable asset; the people you let work on it should treat it that way.
