25 Questions to Ask Before Choosing a Screeding Subcontractor

Whether you're managing a high-spec fit-out or a fast-moving residential scheme, one thing is certain:

Your screeding subcontractor can either protect your programme - or derail it.

We’ve seen it all over the years. Screed packages handed to the cheapest bidder, only to end up with delays, rework, and missed handover dates.

That’s why we created this checklist - to help contractors, site managers, and commercial teams choose partners who deliver certainty, not stress.

Why This Matters

If you’re not asking questions like these up front, you’re relying on hope - and hope doesn’t protect your programme.

A reliable screeding subcontractor should bring more than materials and labour. They should bring:

• Programme certainty

• Technical expertise

• Transparent communication

• A process you can trust
