About our new build mastic in Bletchingley
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We work on bathrooms & en suites, plot handovers and show homes, and the jobs we see most are gaps opening as the house dries out and settles and sealant work across a run of new homes.
Somewhere as small as Bletchingley, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Whatever the size of the job, it’s backed by our one-year guarantee.

The process
Before we leave, we go over the finished joints with you. The work normally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. Somewhere as small as Bletchingley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in

Is it worth trying it myself?

If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.

Why act early in Bletchingley
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. In a small place like Bletchingley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and send you a clear quote before any work starts.

Different surfaces, different methods
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and primer used where needed.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.

What else we do in Bletchingley
Looking after it afterwards
So the new joints stay in good condition:
- Avoid scourers and strong chemicals on sealant
- Use the extractor fan every time you shower
- Photograph failed sealant before it’s redone
- Keep water off fresh sealant until it has cured
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture doesn’t sit on the sealant.
Early snagging is easier snagging. Left alone, a small crack can become a leak.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
