Installing or replacing windows isn’t just about looks, it’s about protecting your home, improving comfort, and saving on energy bills. The right contractor ensures every window is fitted correctly and sealed properly.
Here’s why it pays to hire carefully:
Proper Installation and Performance: Verified contractors will make sure your windows are level, insulated, and sealed to prevent drafts, leaks, or condensation. Poor installation can cause long-term issues like water damage and heat loss.
Energy Efficiency and Code Compliance: Canadian homes face strict energy and building standards. The right window contract will understand local codes and can install ENERGY STAR® rated products that help reduce heating and cooling costs year-round.
Access to Quality Materials and Warranties: Choose window companies that work with trusted suppliers and ensure both materials and labour are covered under warranty, protecting you if anything goes wrong.
Expert Advice and Custom Fit: From choosing the right frame materials to selecting double or triple glazing, contractors can guide you through options that suit your home’s design, budget, and energy goals.
By using HomeStars to find a window contractor, you enjoy several benefits:
Generally speaking, windows aren’t something you replace very often. So when it’s time to take on this project, it helps to know what to ask before hiring a local contractor to make sure you’re getting the right expertise, materials, and long-term value.
Are you licensed and insured?
Window contractors must follow provincial and municipal regulations, so licensing requirements vary by region. Ask your contractor whether they hold a valid trade licence for window installation, and confirm they carry public liability insurance and workers’ compensation coverage. This protects you from being held responsible if an accident or damage occurs during the job.
Do you provide a written quote and what’s included?
A professional contractor should provide a detailed, written estimate outlining:
Do you handle permits and inspections?
In many municipalities, window replacement requires a building permit, especially when altering window sizes. A contractor should understand local bylaws and handle any required paperwork or inspections for you.
Do you offer a warranty or workmanship guarantee?
Most window manufacturers offer warranties on the product itself (often 20 years or more), but you’ll also want to confirm a labour warranty on installation — ideally 5–10 years. A good contractor stands behind their work and will address issues like leaks or condensation without additional cost.
When could you start, and how long will it take?
Window replacements can usually be completed in a day or two, depending on how many windows you’re replacing. Ask about scheduling and how long the job will take from order to completion, especially if custom sizes or weather delays are possible.
Not all contractors are comfortable with non-standard window designs. If your home has bay, bow, arched, or large picture windows, confirm that your installer has experience with these types and can provide a structural and aesthetic solution that fits your home.
Removing and disposing of old windows can be messy and time-consuming. Confirm whether the contractor includes safe removal, recycling, or disposal of old windows in their service.
Accidents are rare, but it’s important to know your contractor’s policy. Ask whether they have insurance coverage for accidental damage and how they handle repair or replacement if something goes wrong. Clear expectations upfront can prevent frustration later.
Older homes may have window openings that aren’t standard sizes. Ask whether the contractor can modify the trim or adjust drywall as part of the installation. Some quotes include finish work, while others do not.
