Why book with us in Carshalton
Fixed written price
The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
Honest about grants
If you might qualify for funding, we tell you before we quote.
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
