Double glazing glass unit is a popular choice for improving your home’s energy efficiency, security, and aesthetic appeal. However, selecting the right company to install your double glazing can feel overwhelming. To help you make an informed decision, the Durajoin team has created a comprehensive guide on what to consider when choosing a double glazing company.

  1. Research and Gather Recommendations

Start by conducting an online search for local double glazing companies. Look for those with strong reviews and ratings on trusted platforms like Trustpilot or Google Reviews. This will give you an idea of their reputation and reliability.

If you’re unsure how to find local double glazing companies, please follow the step-by-step tutorial below. If live in London and don’t have time, Durajoin team has worked hard to create top 5 double glazing supplier in each borough of London.

Step 1: Use localized keywords to search for nearby companies.

Step 2: Go to Google Maps: https://www.google.co.uk/maps. Make sure to turn on your GPS. Once it detects your current location, search for terms like “double glazing company near me,” “best double glazing company near me,” “double glazing window company near me,” or “windows and doors near me.” Alternatively, you can add your area or city name instead of using “near me.”

Step 3: You’ll see sponsored and organic results. Sponsored results are paid advertisements, so it’s better to focus on the local companies, like the example of Durajoin.

Step 4: Create a list of five nearby companies. Search for each one on Google to gather reviews on Trustpilot and other platforms. Read the reviews to understand customers’ experiences. You may notice that some companies have many reviews while others have fewer. Don’t make your decision solely based on the number of reviews, as some business owners may not be tech-savvy and might not ask customers to leave feedback. However, they could still have extensive experience and good offerings. It’s subjective. Once you have your list, reach out to all the companies for quotes.

Additionally, gather recommendations from friends, family, or neighbors who have recently had double glazing installed. Personal experiences often provide valuable insights into the quality of a company’s products and services.

  1. Verify Accreditation

Reputable companies will hold accreditations from leading organizations. You need to ensure that the company you choose is certified by recognized trade organizations such as:

  • FENSA (Fenestration Self-Assessment Scheme)
  • CERTASS (Certification and Self-Assessment)
  • GGF (Glass and Glazing Federation)
  • Secured by Design

These certifications show that the company complies with industry standards for installation and building regulations. Many lead generation companies display false accreditations on their websites. You can verify certifications by visiting the official website.

  1. Compare Quotes and Pricing

Request multiple quotes from various companies to compare prices. Be wary of companies that provide prices significantly lower than their competitors, as this may suggest inferior materials or workmanship. A clear quote should include:

  • The cost of materials
  • Installation fees
  • Warranty details
  • Any additional charges

We always recommend our customers to compare quotes on a like-for-like basis, as this allows them to see significant value. Sometimes, many of our clients come to us claiming they have received quotes for aluminum windows and doors at a 30% discount compared to our initial quote. When we ask them about the aluminum profiles they would receive from that company, they often have no idea.

We have tried reaching out to that companies to understand their offering, and we frequently notice that lower-priced quotes are associated with low-quality aluminum profiles, which is the reason for the lower prices. Customers who choose low-quality profiles often find themselves facing numerous issues with insulation and other faults.

We highly recommend investing in high-quality, value-for-money profiles to avoid any concerns about your windows and doors for decades to come.

  1. Inspect the Quality of Products

Not all double glazing products are created equal. Ask about the specifications of the windows they offer, including:

  • Energy efficiency ratings (e.g., A++ to E)
  • Glass type (e.g., low-emissivity glass, toughened glass)
  • Frame material (e.g., uPVC, aluminum, wood)

High-quality materials contribute to better insulation, durability, and security.

  1. Check Warranty and Aftercare Services

A reliable company will provide a comprehensive warranty that covers both the product and installation. Typical warranties range from 10 to 15 years. Make sure you understand which material get covered by warranties. Mostly frames get warranties. Additionally, inquire about their aftercare services, such as maintenance and repair support.

  1. Visit Showrooms or Request Samples

If possible, visit the company’s showroom to see and assess the quality of their products. Alternatively, request samples or brochures to evaluate the materials, finishes, and styles they offer.

  1. Assess Customer Service

Pay attention to the company’s customer service throughout your interactions. Are they responsive to your inquiries? Do they provide clear and detailed answers? A company that values customer satisfaction will prioritize communication and transparency.

  1. Confirm Installation Timeline

Discuss the expected timeline for your project and ensure it aligns with your schedule. Reliable companies will provide a clear plan and keep you informed of any delays or changes.

  1. Check for Financing Options

If budget is a concern, ask about financing options or payment plans. Many reputable companies offer flexible payment solutions to make double glazing more affordable.

  1. Read the Contract Carefully

Before signing any agreement, read the contract thoroughly. Ensure it includes:

  • A detailed breakdown of costs
  • The agreed timeline
  • Warranty terms
  • Terms and conditions

Seek clarification on anything you don’t understand to avoid unexpected surprises later.

  1. Avoid Lead Generation companies

When conducting online research to find window and door companies, you may encounter numerous lead-generation companies that create fake websites and local business listings on Google Maps, many of which are associated with businesses that do not actually exist in those locations. Additionally, several websites offer comparison services for double glazing companies. Be aware that when you provide your information, these sites often sell your data to various double-glazing companies. As a result, you may receive numerous sales calls from different companies. To protect your data and privacy, it’s best to avoid these types of companies.

Conclusion

Choosing the right double-glazing  windows company is a crucial step in enhancing your home’s comfort and value. By following these tips and conducting thorough research, you can find a trustworthy company that delivers quality products and professional installation. Take your time, ask the right questions, and make an informed decision to enjoy the long-term benefits of double glazing.
