Frequently asked questions
+What's the minimum job lot in Cardiff?
Most Wales sellers set one pallet as the minimum. Sub-pallet quantities revert to per-unit pricing.
+Can mineral wool get wet?
Recovers if it dries fully within 48 hours. Prolonged saturation permanently reduces R-value.
+Can I split a job lot with another buyer?
Yes — SurplusBuilder listings often show "split available". Coordinate with the seller before payment.
