FAQ
- Which materials can I estimate?
- Plasterboard sheets, timber studs at a spacing you set, or flooring packs from the coverage on the carton.
- Is waste included?
- Plasterboard and flooring include the waste percent you set (10% by default). Studs are a count of centres plus both ends, with optional extras for openings.
- Are these order quantities?
- They’re a ballpark from the measurements. Openings, corners, and offcuts on site will change the real order. Confirm pack sizes at the supplier.
