Built for rendering subcontractors, small teams and growing businesses

A render quotation involves more than multiplying square metres by a rate. The system build-up, substrate preparation, window reveals, beads, access, protection and colour can all affect the price. SubCon keeps those decisions alongside the estimate, quotation and job record so the scope is easier to review, explain and update.

Frequently asked questions

Can I calculate a rendering estimate by square metre?

Yes. Record the measured area and build up your labour and material allowances, then add access, preparation and other project costs. Check deductions, reveals and elevations against the agreed measurement method.

Can I quote for silicone render, monocouche and EWI?

Yes. SubCon supports estimating workflows for these systems. Keep the specified manufacturer, materials, finish and installation scope with the relevant job before issuing the quote.

What should I include in a rendering quotation?

Define the substrate and system, preparation, areas, reveals and edges, access, protection, waste, colour, exclusions, payment stages and any variations. Confirm the exact scope with the customer.

Can I track extra rendering work and retention?

SubCon keeps variations, invoices and retention records linked to the project so additional work and payments are easier to follow.
