Finglesham New Build Mastic
Problem with your new-build sealant joints in Finglesham? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- New-build shower sealant that has already split
- Beads laid onto grit and dust from the build
- Worktop and upstand sealant coming away
New build mastic in Finglesham, done properly
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. If you’re dealing with smeared, uneven beads picked up at snagging and cracks appearing as a new home settles, we can put it right, whatever the surface.
Somewhere as small as Finglesham, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Whatever the size of the job, you get the same 12-month guarantee in Finglesham and across Kent.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

What should I tell you?

Do I need to be at home?

Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.

It depends on the product. Some smell for a while, some hardly at all.
When it is not the sealant
New sealant cannot fix everything, and we’ll tell you before any work starts. It will not solve:
- Baths and trays that move too much for sealant to cope with
- Leaking fittings rather than failed sealant
- Cracked trays, tiles or worktops
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
What we seal
- Bathrooms & en suites
- Plot handovers
- Skirting & floors
- Windows & doors
- Kitchens
- Show homes
When to call us in Finglesham
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
Common reasons people contact us include:
- Worktop and upstand sealant coming away
- Leaking shower tray seals in a new home
- Sealant that never bonded to the surface
- Cracked sealant around new window and door frames
If you’ve bought a new home near Sandwich station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before booking
- Are they insured?
- How the colour is chosen
- Is the old sealant removed completely?
- What the cure time is
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. Somewhere as small as Finglesham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- 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.
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
- Mention any tricky access

What else we do in Finglesham
What the job involves on each surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out and baths are filled before sealing.
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Photograph failed sealant before it’s redone
- Report sealant problems to your builder during the snagging period
- Check bath and shower seals every few months as the house settles
- Avoid scourers and strong chemicals on sealant
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
Landlords, agents and businesses in Finglesham
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured.

New homes and floors in Finglesham
Finglesham is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
