Why the price varies. Every Posi-Joist is made to measure, so the price depends on the depth, the length, the joist centres and the loads your floor carries.
What’s included. Every online order comes with a design drawing and structural calculations for building control. For full floors, we design and price the whole scheme for free.
What’s extra. Hangers, straps and strongbacks, delivery and VAT. You can also collect free from our yard in Swanmore.

Comparing quotes? Look at the whole floor, not the price per metre. Fewer joists and no notching for services often make a Posi-Joist floor cheaper overall.

A price per metre is a useful starting point, but the real cost of a floor depends on the whole design. That is why every quote comes with a free design and calcs.
