About our new build mastic in Aldingbourne
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference. If you’re dealing with kitchen sealant that has pulled off the wall and gaps opening as the house dries out and settles, we can help, on skirting & floors, windows & doors and plot handovers alike.
In a village or hamlet like Aldingbourne, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Big or small, you get the same one-year guarantee in Aldingbourne and across West Sussex.

Common problems we fix in Aldingbourne
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Most people get in touch after spotting something like this:
- Sealant applied over dusty or wet surfaces
- Sealant work across a run of new homes
- Shower seals failing in the first year or two
- Cracks appearing as a new home settles
For new homes near Barnham station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- Which colour the sealant will be
- What the quote includes, VAT included or not
- Who turns up on the day
- How long the guarantee is
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Leaking fittings rather than failed sealant
- Cracking that points to a structural problem
- Deciding who is responsible under a builder’s warranty
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

Different surfaces, different methods
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Resist patching a failed seal with a tube from the DIY shop
- Put sealant faults on your snagging list early
- Open a window or run the fan after bathing
- Wait for the cure time before using a resealed shower
Do not stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.
