How we handle new build mastic in Mersham
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first. We work on show homes, bathrooms & en suites and plot handovers, and the jobs we see most are gaps between new skirting and floors and kitchen sealant that has pulled off the wall.
Older homes in small places like Mersham often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Common problems we fix in Mersham
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
Signs it’s time to call us include:
- Messy sealant that spoils new finishes
- Gaps between new skirting and floors
- Sealant applied over dusty or wet surfaces
- Gaps opening as the house dries out and settles
For new homes near Ashford International station, it’s worth checking the sealant early, while snags are still fresh.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Use the extractor fan every time you shower
- Put sealant faults on your snagging list early
- Clean sealant with mild detergent, not abrasives
- Resist patching a failed seal with a tube from the DIY shop
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you.
Questions from Mersham
I let a flat near Ashford International station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Mersham?
Yes, Mersham is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
How long will you be here?
Typically it takes a few hours in a single home. Larger jobs naturally take longer.
Is it worth resealing while the house is still settling?
Any seal that is leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Can you match the sealant colour to my new kitchen or bathroom?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
How the job changes by surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one that suits the frame.
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there suited to the job.
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
