If you're a window and double glazing installer in the UK, you've probably had your fair share of leads that ghost you after the quote.
The customer seemed interested, the quote was fair, and then... nothing.
Sound familiar?
The truth is, most double glazing firms lose jobs not because of price, but because of poor follow-up, lack of trust-building, or timing. In this post, we'll walk through simple, proven ways to convert more window leads into paying jobs — without needing to undercut yourself or race to the bottom.
🔍 Why Your Window Quotes Are Being Ignored
Let's start with the main reasons customers don't respond to glazing quotes:
- They forget who you are
- They get overwhelmed by too many similar quotes
- They don't understand the value of what you've offered
- They're unsure if they can trust you
- They're still waiting for more quotes
None of these reasons are about price.
Which means you can win more jobs by improving how you follow up, how you position yourself, and how you build trust.
🧠 Step 1: Qualify the Lead Properly Upfront
If someone calls you about a new window install, don't just quote them straight away. Take time to understand:
- Are they the homeowner?
- Are they actively gathering quotes?
- Have they set a timeframe for the work?
- What's driving their decision? (e.g. energy savings, noise reduction, appearance)
When you understand their priorities, you can tailor the quote and follow-up to match — which massively increases your chances of getting the job.
✍️ Step 2: Make Your Quote Easy to Understand and Easy to Trust
Many glazing companies send over a flat number and leave it at that. But homeowners want to feel informed and confident.
Improve your quote by including:
- A breakdown of what's included (frames, glass type, energy rating, warranties)
- A few bullet points on why your products are high quality
- Clear timelines and what happens next
- A photo or short intro about you or your company (adds trust)
This makes your quote feel more like a professional proposal, not just a number on an email.
📞 Step 3: Follow Up Like a Professional (Not a Salesperson)
This is where most glazing installers drop the ball.
You send the quote. Nothing happens. You think they've gone cold. You move on.
In reality, they're just waiting to be nudged.
Here's a follow-up schedule that works:
- 1 day after the quote:
"Hi [name], just checking you got the quote okay. Let me know if you have any questions." - 3 days after:
"Hi [name], just wanted to see if you'd had a chance to look at the proposal. Happy to jump on a quick call if that helps." - 7 days after:
"Hi [name], if you're still interested, we've got a few slots left this month. I can hold one for you if needed."
Friendly, low-pressure follow-up like this shows professionalism — and helps you stay top of mind when the customer is ready to decide.
⭐ Step 4: Use Local Proof and Reviews
You're a local business. Use that to your advantage.
Whenever possible, mention:
- Work you've done nearby
- Before and after photos of similar projects
- Links to your Google reviews or Checkatrade profile
- Any accreditations (FENSA, Certass, etc)
This builds confidence and helps the homeowner see you as the safe, professional choice — even if you're not the cheapest.
🧾 Step 5: Add a Simple Reason to Say Yes
If the customer is on the fence, a small incentive can help.
Try things like:
- "If you confirm by Friday, we can book your install before [hot weather / holiday / energy bill rise]"
- "We're including a free energy-rated upgrade this month only"
- "We've got leftover stock in your window size — I can pass the saving on if we act quickly"
You don't have to cut your full price — just frame the decision to act now as a smart one.
✅ Bonus: Track Your Conversions
If you're not tracking how many quotes become jobs, start now.
Even a simple spreadsheet with:
- Name
- Date quoted
- Quote amount
- Status (won, lost, ghosted)
…can help you spot patterns and improve over time.
If you realise 7 out of 10 quotes never get followed up — you've just found your biggest opportunity for growth.
Final Thoughts: It's Not About Being the Cheapest — It's About Being the Smartest
In 2025, homeowners are still investing in double glazing — but they're being more selective than ever.
If you want to convert more window leads into booked jobs, focus on:
- Stronger first conversations
- Clearer, more confident quotes
- Consistent, friendly follow-ups
- Trust-building with reviews and proof
- Giving them a reason to say yes now
These simple steps can double your conversion rate — without ever touching your prices.
