New build mastic for homes and businesses in Lower Slackstead
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We are often asked to deal with gaps behind new kitchen upstands and gaps between new skirting and floors, across kitchens, plot handovers and show homes.
Older homes in small places like Lower Slackstead often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Related advice
What we’re called out for in Lower Slackstead
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint.
Look out for any of the following:
- Gaps opening as the house dries out and settles
- Beads laid onto grit and dust from the build
- Untidy sealant flagged on a snagging list
- Kitchen sealant that has pulled off the wall
If you’ve bought a new home near Romsey station, the sealant around baths, showers and frames is worth checking in the first year or two.

Other services in Lower Slackstead
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Why deal with it now?
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Around Lower Slackstead, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
For anyone letting property in or around Lower Slackstead, several properties can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
How to look after the new joints
To keep the joints looking good and working properly:
- Check bath and shower seals every few months as the house settles
- Use the extractor fan every time you shower
- Keep pictures and emails about snagging items
- Act quickly if a seal starts to leak
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left over time.
Different surfaces, different methods
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there suited to the job.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing to keep callbacks down.
