Have questions about how we rank or list top-rated windows and doors companies? This FAQ covers our selection process, review standards, and what it means to be featured on Mullions.

For Homeowners

How does Mullions choose which companies to feature?

We use a proprietary 30-point review process to evaluate companies on service quality, business integrity, reputation, and customer value. Only those that meet our criteria are listed.

No. Listings on Mullions are entirely merit-based. Companies cannot pay to be featured or ranked—this helps us stay unbiased and trustworthy.
A top-rated company consistently demonstrates quality workmanship, fair pricing, responsive customer service, and solid online reviews, all verified through our 30-point inspection.
We don’t do in-person visits. Instead, we conduct extensive online research using public records, customer reviews, and company websites. We also test contact responsiveness.
It’s a checklist we use to evaluate each business across categories like licensing, insurance, website quality, service clarity, customer reviews, and reputation. You can read the full list on our Review Standard page.
Not yet. We focus on select cities like Toronto, Vancouver, and Calgary, where we can thoroughly review and maintain high-quality listings. More cities will be added over time.
We limit listings to ensure exclusivity and focus. This helps homeowners make clearer decisions and gives top-performing businesses a meaningful spotlight.
Our team updates listings quarterly or sooner if we receive a correction request or discover major changes (e.g., company closure or poor performance).
We gather info from official company websites, public directories, licensing bodies, review platforms, and direct communication with businesses.
Yes. We only use verified review sources and analyze review patterns to screen for manipulation. We also consider recency, volume, and depth of feedback.

Please email us at [email protected]. We will verify the business status and remove or update the listing accordingly.

We are a ranking site. We don’t collect reviews directly but use them as part of our evaluation process to help rank trusted businesses.

For Businesses

Can I submit my business to Mullions for review?

Yes. Visit our contact page or email [email protected] to request a review. If your company meets our 30-point criteria, we may include you in our next update.

Even if there are listings, we periodically reassess companies. New submissions are considered during our update cycles, and strong candidates may replace underperforming ones.
As long as the business continues to meet our criteria. We review listings regularly and remove companies that fall below our standards.
All featured companies meet the same high standards. Positioning is for layout purposes only and doesn’t reflect a numerical rank.

Absolutely. If you notice incorrect details, contact us at [email protected]. We’ll verify and update your listing promptly.

Yes. We provide badges and promotional assets you can use on your website or marketing materials to showcase your Mullions listing.
It means your business has passed our independent 30-point review and is recognized for quality, trust, and local relevance in your city.
We look at overall review trends. A few negative reviews don’t disqualify a company, but consistently poor feedback or unresolved complaints may prevent listing.
We do not list businesses that show a pattern of discriminatory, unethical, or illegal behaviour. Community trust is central to our platform.
Yes. These details strengthen a company’s profile and help us evaluate professionalism and product expertise.
