Different surfaces, different methods
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing and primer used where needed.
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
New build mastic in Ayres End, done properly
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. If you have smeared, uneven beads picked up at snagging and shower seals failing in the first year or two, we can help, on show homes, kitchens and plot handovers alike.
Older homes in small places like Ayres End often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Each job carries a 12-month guarantee.

How it works
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the number of plots, and we explain the cure time before we leave. For a village or hamlet like Ayres End, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. 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.
Getting ready for the visit

Common problems we fix in Ayres End
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
These are the problems we’re asked about most:
- Cracked sealant around new window and door frames
- Leaking shower tray seals in a new home
- Second-fix sealing on new plots
- Skirting joints opening in the first winter
Around Ayres End, as everywhere, new build mastic is only as good as the preparation behind it.

Looking after it afterwards
Looking after new joints is easy:
- Clean sealant with mild detergent, not abrasives
- Ventilate bathrooms well, especially in the first year
- Keep water off fresh sealant until it has cured
- Do not seal over failed sealant yourself
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
DIY versus a professional finish
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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
