Your Ultimate Guide to Choosing the Right Glazing Expert in London
Choosing the right glazier is one of the most important decisions any homeowner in London can make . Whether you’re upgrading to double glazing for better insulation , repairing a smashed shopfront with emergency glazing , or transforming your home with architectural glass installations , the professional you hire will directly affect the quality , durability , and cost of the project .
Yet , many homeowners rush into hiring the first glazing company they find — and often regret it later . From hidden costs to poor-quality workmanship , the wrong choice can lead to frustration , wasted money , and security risks .
This guide is designed to help you avoid those pitfalls . Here , we’ll cover the key questions you should always ask your glazier before hiring them — questions that reveal their experience , reliability , and suitability for your project .

1 . How Long Have You Been Working in the Glazing Industry?
Experience matters — a lot . A glazier with 10+ years in the industry has likely seen and solved every possible challenge . They know how to handle complex installations , work with a variety of materials , and anticipate problems before they arise .
When you ask about experience , don’t settle for vague answers like “a long time .” Request specific details:
- How many years have they been operating in London?
- What types of projects have they handled — residential , commercial , or both?
- Do they have experience with specific services like Double Glazing in London or Emergency Glazing?
Pro Tip: Look for glaziers with at least 5–10 years of experience and a proven track record in the type of project you need .
📞 At Glazing London , our team brings over 20 years of combined experience to every project , ensuring flawless results from consultation to installation .

2 . Are You Fully Licensed and Insured?
Never hire a glazier without confirming their licenses and insurance . A legitimate glazing company should:
- Hold the proper certifications required by UK building standards .
- Carry public liability insurance to protect your property in case of accidents .
- Be registered with recognised trade bodies or glazing associations .
If a company hesitates to show documentation , consider it a red flag .
Bonus tip: Check whether they comply with FENSA or CERTASS regulations , which ensure your installation meets UK building codes .

- Attention to detail
- Range of glazing solutions they offer

4 . What Types of Glazing Services Do You Offer?

- Double Glazing London: Ideal for improving insulation and reducing noise .
- Emergency Glazing: Essential for break-ins , accidents , or storm damage .

5 . What Materials Do You Use , and Why?
The quality of materials directly affects the performance and longevity of your glazing . A good glazier will be transparent about what they use and why .
Questions to ask:
- Do they use energy-efficient glass that meets UK standards?
- What types of frames do they offer — uPVC , aluminium , or timber?
- Do they provide options for security glazing or laminated glass?
📌 We use only high-performance , energy-efficient glass and industry-leading frames to ensure your installation lasts for decades .
6 . How Do You Handle Emergency Glazing Situations?
Glass emergencies require fast , reliable , 24/7 service . If a glazier doesn’t have a dedicated emergency team , you could be left vulnerable for hours — or even days .
Ask:
- Do you offer same-day response for emergency glazing in London?
- What is your typical response time?
- Will you provide board-up services if glass replacement isn’t immediately possible?
🛠️ Our emergency glazing team is on standby 24/7 . We aim to arrive within hours anywhere in London , securing your property and restoring safety fast .
7 . Can You Explain the Full Installation Process?
A professional glazier should walk you through the process step by step . This shows transparency and helps you understand what to expect .
Typical stages include:
- Initial Consultation: Discuss needs , budget , and goals .
- Site Survey: Measurements , safety checks , and recommendations .
- Quote & Agreement: Transparent pricing with no hidden fees .
- Installation or Repair: Work completed efficiently and cleanly .
- Final Inspection: Ensuring quality and customer satisfaction .
Tip: Ask about timelines and potential delays so you can plan accordingly .

8 . What Warranties or Guarantees Do You Offer?
A glazing company confident in its work will offer clear warranties on both materials and workmanship . Standard coverage ranges from 5 to 15 years depending on the service .
Ask about:
- Length and terms of warranties
- What’s covered (e .g . , seals , frames , glass , labour)
- Whether they provide aftercare support
📜 We offer up to 15 years of warranty on our double glazing installations , giving homeowners peace of mind for years to come .

A trustworthy glazier will be upfront about possible complications . Ask how they handle:
- Structural issues discovered during installation
- Difficult access points or scaffold requirements
- Additional materials not included in the original quote
Transparency here helps you avoid budget surprises later .
10 . Can I Speak to Past Clients or Read Reviews?
Nothing builds trust like hearing from other homeowners . A reputable glazier should happily connect you with past clients or direct you to verified reviews .
