Can I do it myself?
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.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
How we handle new build mastic in Cramhurst
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on kitchens, windows & doors and show homes, and common reasons people get in touch are gaps opening as the house dries out and settles and plot mastic for developers ahead of handover.
Work in a small place like Cramhurst just needs the journey and access planning, and the work itself is the same as on any site.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours in a single home. Somewhere like Cramhurst needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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’re working on
- Try not to wet indoor joints just before the visit
- Tell us if parking is tricky
How to get a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.

Aftercare tips
So the new joints stay in good condition:
- Put sealant faults on your snagging list early
- Look at the sealant regularly in the first couple of years
- Use the extractor fan every time you shower
- Photograph failed sealant before it’s redone
Do not stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.

Why act early in Cramhurst
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time and most come down to preparation. Where a wall is exposed, as many are in small places like Cramhurst, wind-driven rain gets into any failed joint, 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 about the job first.
