Commercial mastic FAQs
Common questions.
Based in Liverpool and covering commercial projects across the North West and nationwide across the UK.
Enquiries from main contractors, developers, facilities teams and commercial property managers are welcome.
Drawings and quantities are ideal, and clear photographs are enough to start the conversation.
Can you price commercial mastic from drawings?+
Yes, where the drawings, joint schedule and quantities are clear. Photos, joint dimensions, substrate details, access information and the programme help us check what is included. Complex or unclear packages may need a site visit.
Do you work on occupied commercial properties?+
Yes. Work can be phased around occupied areas and agreed working hours. We need to know access restrictions, operational constraints and any permit or induction requirements before the start date.
Can you remove and replace failed sealant?+
Yes. Existing sealant can be cut out, the joint cleaned and the replacement system applied. We first need to understand why it failed, the substrates involved and whether the joint detail is suitable.
What access methods can you work from?+
We can plan work from ground level, scaffolding or MEWPs, depending on the site. Rope-access work is delivered with an established qualified rope-access team and is quoted separately.
Do you provide RAMS and insurance details?+
Yes. Risk assessments, method statements and public liability insurance details can be provided for commercial and site-based work.
Which areas do you cover for commercial work?+
We carry out commercial mastic and construction packages across Liverpool, Manchester, St Helens, Warrington, the wider North West and nationwide across the UK. Travel and site accommodation are built into the project quote where required.
