New build mastic in Haslingbourne, done properly
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. If you are dealing with gaps opening as the house dries out and settles and plot mastic for developers ahead of handover, we can help, whatever the surface.
In a village or hamlet like Haslingbourne, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Your job is guaranteed for a year, as with all our work.

Different surfaces, different methods
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
Show homes
We seal show-home bathrooms, kitchens and frames. Tell us when the home is open so we can plan around it.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Keeping the joints in good condition
Aftercare is simple:
- Wipe joints with warm soapy water
- Check bath and shower seals every few months as the house settles
- Record problems with dated photos
- Put sealant faults on your snagging list early
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day before water reaches them.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
Why act early in Haslingbourne
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Older cottages and farmhouses around Haslingbourne can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

Common problems we fix in Haslingbourne
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
Most people get in touch when they notice one of these:
- Cracked sealant around new window and door frames
- Gaps behind new kitchen upstands
- Sealant applied over dusty or wet surfaces
- Skirting joints opening in the first winter
If you’ve bought a new home near Pulborough station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before you book
- How hidden problems are handled
- Whether all the old sealant comes out first
- Whether the sealant suits the joint
- When the joint can take water or movement
