New Build Mastic in Aylesham
Our applicators work in Aylesham on plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly.
- Cracks appearing as a new home settles
- Sealant that never bonded to the surface
- Smeared, uneven beads picked up at snagging
How we handle new build mastic in Aylesham
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. We work on bathrooms & en suites, kitchens and skirting & floors, and common reasons people get in touch are worktop and upstand sealant coming away and sealant that never bonded to the surface.
Where new homes go up in smaller places like Aylesham, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.
Every job is covered by our one-year guarantee.

Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Why act early in Aylesham
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Around Aylesham, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Should I try it myself first?
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.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The process
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. For a job in Aylesham, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
How to prepare
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can

Aftercare tips
Aftercare is simple:
- Open a window or run the fan after bathing
- Get a leaking seal dealt with right away
- Photograph failed sealant before it’s redone
- Avoid scourers and strong chemicals on sealant
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers so moisture does not sit on the sealant.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.
