Which joints should you check before moving, selling or renting out a home?

Make a simple condition map

Distinguish surface stains, detached edges and damp outside the wet area. Photograph the starting condition. A colour change may improve appearance; a leak needs diagnosis before a viewing or handover.

For a dry interior joint that will be painted, check the expected movement against the data sheet for OTTOSEAL A205. Try the finish with your actual paint.

Dry-fit the FUGENFUX profiling tool. Choose the edge that meets both sides without scooping out the middle, then tool the bead before a skin forms.

Allow time before first use

Follow the cartridge instructions for actual site conditions. Arrange another bathroom if needed. Keep the product reference and application date for the next occupant. A fresh bead does not demonstrate that the whole installation is watertight.

Before opening the cartridge, try the Presch silicone gun in the tightest corner. Check you can turn your wrist and release pressure at the end of the run.

Work backwards from moving day

Start with the day the shower must be available. Allow for removal, preparation, drying where needed and curing. If you have only one afternoon, do not strip every joint before arranging how the bathroom will be used tomorrow.

Where the detail calls for sanitary silicone on two compatible surfaces, consider OTTOSEAL S100. Porous stone needs a stone-compatible product.

Should I replace every joint before handover?

Keep joints that are sound and functional. Record any unresolved leak instead of hiding it under new sealant.
