Can sticking doors and windows mean I need restumping in Bendigo?

Yes, sticking doors and windows can mean you need restumping in Bendigo when they start jamming at the same time as floors slope, cracks open around architraves or gaps appear under skirting boards. In Bendigo's older timber housing, reactive clay can shift seasonally and drop parts of the subfloor, which twists the frame enough to throw door openings out of square. That does not automatically mean a full reblock, but it is a strong reason to get the stumps, bearers and floor levels checked before you spend money trimming doors or patching plaster. Ask whether the quote includes a subfloor inspection, laser levelling and any joist repairs found once access is gained.
