About Us


Seasonmaster was formed in 1985 by Andrew Fletcher and Gerda Fletcher making secondary glazing to the retail and trade. In 1994 his son, Gary Fletcher, came into the business after leaving school, and since around 2010 Gary has been running the company along with his wife Zuzana.

Since we all came back to work after Covid Gary has introduced more products (bi folding doors and patio doors) and the company has gone from turning over around 400k a year to over a million a year in the last couple of years. We continue to grow slowly.

We pride ourselves on remaining family-owned; giving customers a good service is our main priority and will continue to be so into the future.

  • We manufacture and fit secondary glazing all over the UK
  • We manufacture Patio Doors and Bi fold doors to the trade and retail (fitting also locally)
  • We supply and fit UPVC windows and doors locally
