When to call us in Ladwell
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Keep an eye out for these signs:
- Beads laid onto grit and dust from the build
- Gaps opening as the house dries out and settles
- Frame joints opening as the plaster dries
- Gaps between new skirting and floors
For new homes near Chandlers Ford station, it’s worth checking the sealant early, while snags are still fresh.

New build mastic in Ladwell, done properly
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. We are often asked to deal with skirting joints opening in the first winter and shower seals failing in the first year or two, across show homes, kitchens and windows & doors.
Around Ladwell, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

How the visit works
We keep the work tidy and contained to the joints we are treating. Expect the work to take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Ladwell, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Clear items away from the joints we are working on
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area

Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Settlement cracks that need a surveyor
- Broken tiles or a split tray
- Baths and trays that move too much for sealant to cope with
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

How the job changes by surface
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Wipe joints with warm soapy water
- Avoid running a DIY bead over the old one
- Act quickly if a seal starts to leak
- Photograph failed sealant before it’s redone
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
