Thermaseal has transformed many properties with homeowners returning for further projects on existing and new properties alike.

Our policy of no pressure sales has allowed customers to take the time to evaluate the benefits of dealing with professionals each step of the transformation from old to new.

Many choose Thermaseal Window Systems on the value of dealing with a traditional company, where customers service is of paramount importance to our customers.

Our products are bespoke with numerous design and colour options to satisfy the precise design and budget requirements of any project.

Themaseal Window Systems independently test our manufactured windows and doors to surpass all the security standards currently specified within our industry. Today they are manufactured using quality fittings, again that have been durability tested to ensure many years of service beyond our standard 10 year guarantee period, giving peace of mind for the homeowner for many years to come.

Customers on future projects frequently personally request our trained installation teams, as they have built up a relationship with them previously. Installations are generally carried out within the Essex area, although we have installed as far away as Nottingham for customers that have relocated.
