Cosyseal Double Glazing

About Cosyseal

Customer Service Lead

Cosyseal is a commercial window and double glazing company based in Croydon, South London. We work with a broad range of customers including architects, surveyors and construction firms, mostly within London and the Home Counties.

We can supply and install all types of PVCu, aluminium and timber windows and doors, conservatories and roof lights, all purpose made to meet the customers requirements.

In addition to installation and refurbishment, we also provide maintenance services, 24 hours a day, 365 days a year.

The unique selling point of Cosyseal is the way we do business. We are customer service focused and believe in developing strong working partnerships with our customers. This is reflected in the length of time that we have worked with them; 10 years in many cases.

Everything we do is based on our core-values of:

  • Working in partnership with customers,
  • Commitment to nurturing the relationship with our customers and working with them for the long term,
  • Conducting our business with respect and honesty,
  • Investing in our staff’s development and training,
  • Recognising that we have a responsibility to our wider community and the environment,
  • Taking the health and safety of our staff and others seriously and
  • Appreciating and embracing diversity.

If you have any dealings with us, you can expect to be treated according to these principles.

We know our customers want the reassurance of dealing with a company that has had the quality of its work independently accredited. Amongst many others, we have been accredited by Construction Line, CHAS, EXOR SAFE contractor and FENSA.

At Cosyseal we take corporate social responsibility (CSR) very seriously. We’re proud to adhere to a strict environmental policy that we have followed for many years. We go out of our way to source materials locally, we recycle old windows, glass and offcuts and have an ambitious aim to reduce energy consumption by 25% by June of next year. Even the company logo acknowledges our green approach as it was inspired by the Save the Seal campaign.

If you chose to do business with Cosyseal, you can rest assured that you are teaming up with a company with a long history. We were founded in 1984 and became a limited company in 2000. Shortly afterwards the company was bought by Rajesh Patel. Rajesh has owned the company ever since and has overseen its successful expansion into the maintenance market.

We don’t just want to fulfil a contract, we want to work with you, understand your needs and provide the highest levels of customer service.
