If you're running a double glazing business and still relying on leaflet drops, Checkatrade or word of mouth, you're likely leaving money on the table. Facebook Ads are one of the most cost-effective ways to generate high-quality leads for window and door installers in the UK.
But there's a catch: most double glazers get it wrong.
In this guide, we'll walk you through how to run profitable Facebook ads for double glazing, what mistakes to avoid, and how to actually turn clicks into consultations.
Why Facebook Ads Work for Double Glazing
Double glazing is a visual product. People love a good before-and-after. Facebook and Instagram, which are both managed from the same ad platform, are the perfect place to show transformations and drive interest.
What makes Facebook Ads powerful for glazing firms:
- Visual targeting: Show off your best installs and attract people who want a similar look
- Hyper-local targeting: Promote within specific postcodes where you've done work or want more
- Lead forms: Facebook lets you collect names, emails and phone numbers right in the app
- Pixel tracking: If you have a website, you can retarget visitors who didn't enquire
Common Mistakes Double Glazing Companies Make on Facebook
Most failed Facebook ad campaigns for glazing boil down to these errors:
- Too generic: "We install windows and doors" isn't enough. People need to see the benefit and transformation.
- Poor photos: Bad lighting, no context, or stock images don't stop the scroll.
- No lead capture: Clicking through to a slow website with no form is a conversion killer.
- No follow-up: Leads go cold if you don't call them within 24 hours.
What a Good Double Glazing Facebook Ad Looks Like
The best-performing ads usually have:
- A real image of a recent installation (ideally a transformation: old to new)
- A clear offer, e.g. "Free Quote in 24 Hours" or "Energy-Efficient Windows Installed From £X"
- A call-to-action, like "Get My Free Quote" that triggers a lead form
- Postcode or area mention to increase relevance (e.g. "Now fitting in Reading and Slough")
Example Facebook Ad Copy (Proven to Convert)
"Tired of cold, draughty windows? Our A-rated glazing keeps the heat in and cuts bills. Now installing in [Your Area]. Click to get your free quote."
Or:
"Another transformation in [Town Name]! See how we replaced 20-year-old windows with modern, energy-saving glazing. Want a quote? Click here — no obligation."
Targeting Tips for Glazing Ads
- Use age targeting: 30–65+ usually performs best
- Homeowners > renters: Use interests like DIY, home improvement, property ownership
- Exclude recent converters: People who just filled out your form
- Create Lookalike Audiences: Based on previous leads
Best Time to Run Ads for Window Leads
- Spring and Autumn tend to convert best (people notice the cold or start renovation plans)
- Run ads Tuesday–Thursday, mornings and evenings
- Boost posts from real installs on weekends
What Budget Should You Start With?
You can get started from as little as £10/day, but £20–£30/day will give you faster data and more consistent leads.
Expect leads to cost anywhere between £10–£40 depending on your location, offer, and ad quality.
Facebook Ads vs Lead Generation Platforms
| Feature | Facebook Ads | Lead Marketplaces (e.g. Bark) |
|---|---|---|
| You own the leads | ✅ Yes | ❌ Often shared with competitors |
| Custom branding | ✅ Your photos, offer | ❌ Generic profiles |
| Cost control | ✅ Set daily budget | ❌ Pay per lead, no control |
| Exclusivity | ✅ 100% yours | ❌ Usually sold to 3–5 trades |
Facebook ads for glazing installers are often a better way to generate leads than lead marketplaces like Checkatrade or Bark, but platforms such as HomebuyerLeads can be a good alternative if you want full control over your postcode areas.
