Choosing the best Double glazing company


Choosing the best UPVC double glazing specialist for your new windows, doors, orangery or conservatory can be hard.

Here’s our top tips for choosing the best double glazing specialist:

Reputation 

Most importantly, review and select your double glazing company carefully – always ask for customer testimonials and references.

Check accreditations

Choose a FENSA double glazing registered company.  FENSA is the industry standard for replacement window and door installers self-certifying compliance with the building regulations.  FENSA is the brand trusted by all local authorities, industry and government – homeowners can to.  FENSA proactively protects consumers from the cowboys.

It is important that you ask every company to back up verbal claims with documentary evidence that they have the required certification.

Quality and performance - choose branded products

Some double glazing companies cut corners in areas you can’t see, like with the sealant used around the window frame.  Low quality materials can quickly start to fail, resulting in costly repairs and maintenance.  Make sure the window and door company you choose provides top quality work, and uses a UPVC leading window supplier.

Guarantees

Most installation companies will offer a guarantee.  The industry standard is based on 10 years. 

Windows doors conservatories security

Check that the glazing company offer double glazed windows and doors designed to include a variety of security features to protect your family and home against criminal intrusion.   With inadequate security measures, a burglar will gain entry to your home in a flash, without being spotted by neighbours in the street. 

Building a conservatory or orangery?

Unfortunately, regulations as they currently stand do not require most conservatories and orangeries to have planning approval or local authority building control. You’ll find that many conservatory builders cut corners – bad news for homeowners.  Choose a reputable conservatory builder that you can trust. 

Choose a company with experienced representatives and a showroom

Get the right advice from an experienced adviser.  Always ask for a written quotation so that you have a record of the scope and specification of the works included in the quotation.  Be suspicious of very low prices and equally suspicious of very high prices.  If you are comparing different double glazing companies, make sure they are offering like for like in terms of product quality.  Ask to see the products, preferably in a showroom where you can compare each design.

Cost against value

Make sure that your getting value for money.  Smaller UPVC window and door companies have less overhead than larger companies and are able to offer a quality service without the high price tag that goes alongside big brand TV and digital advertising campaigns.

Find a local double glazing installation company

Find recommended double glazing companies in your area.  You are more likely to get a better service from an established local company.
