Master Window and Door Conservationists

Few companies in the United Kingdom focus on preserving original windows and doors rather than replacing them. As a result, the competition to replace these landmark fixtures has become overwhelming and the voice of conservation has become jeopardised. It is our sworn duty to stand up and inspire passion for our British heritage.

Fortis & Hooke provides a dependable, long-lasting alternative to replacement, ensuring true value for money for all homeowners.

         The Greenest Option

The preservation of original windows and doors is the most environmentally friendly option.

In most cases, the preservation of your original timber windows and doors is the best-case scenario for the environment. A study done by Greenpeace supports this view:

“… However, even without taking into account environmental impacts of major pollutants, the report finds PVC to be the worst of the options it considered for windows and floors. This is because timber and linoleum use less energy, contribute less to global warming gases, use fewer non-renewable resources and generate less waste.”

The report also warns of the dangers alternatives pose:

“The production and disposal of PVC-u windows leads to the release of highly poisonous chemicals which threaten the environment and human health. PVC-u production involves no less than six of the fifteen most hazardous chemicals listed by European governments for priority elimination. Timber is a sustainable resource. As long as the timber is sourced from properly managed forests and care is taken in the choice of preservatives, paints and stains, timber windows are by far the best environmental choice.”
