Why insulation work fails
Insulation and waterproofing are invisible when done well and catastrophic when done badly, which is why clients who have been burned once become extremely cautious buyers. They need to know which system suits their surface and exposure, what thermal or waterproofing performance to expect, and what the warranty actually covers. Contractors who publish a material list and a per-metre price compete only against whoever quoted less for an unspecified system.
What we build for an insulation contractor
First, system selection by surface, exposure and application, since choosing wrongly is how this work fails. Second, thermal and performance calculations showing expected results, which is what justifies the cost against a cheaper quote. Third, cost per square metre by system with what is included. Fourth, warranty terms and project references, because a client who has paid twice is buying reassurance more than material.
