Our Process
How It Works
Survey & Specification
Get in touch to arrange a survey, and we will come out and assess the surfaces and joints to be sealed and advise on products and colours. We will then provide you with a quotation and, once accepted, arrange an installation date.
Preparation
Whether it is a cut out and reseal or a new application, we make sure all surfaces are clean and debris-free, with wider joints sufficiently filled using foam or backer rod.
Application & Finish
We apply the appropriate sealant and tool it for a neat, professional finishing touch to your project.
Quality in Every Detail

FAQ
Frequently Asked Questions
Cure time depends on the silicone type and ambient conditions; skin forms in minutes but full cure can take 24–48 hours in typical interior conditions. External, cold or humid conditions can slow cure; we factor this into our programme and advise on ventilation and use during cure.
