New build mastic for homes and businesses in Rowfant
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. Typical jobs include worktop and upstand sealant coming away and internal frame sealant that has split, across windows & doors, show homes and kitchens.
In a village or hamlet like Rowfant, 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.
You’re covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or email us.

Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Where a wall is exposed, as many are in small places like Rowfant, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Use the extractor fan every time you shower
- Raise failed sealant with the developer while you are covered
- Follow the cure time we give you
- Watch for new gaps as the house dries out
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
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.

Will you just run a new bead over the existing one?
No. New silicone won’t bond to old silicone, so it soon lifts and traps water. The old sealant always comes out first.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Is it normal for sealant to crack in a new home?
Cracking in the first couple of years is common. Rushed application on dusty surfaces makes it worse.
