Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
Keep an eye out for these signs:
- Leaking shower tray seals in a new home
- Sealant applied over dusty or wet surfaces
- Gaps behind new kitchen upstands
- Joints pulling apart as timber shrinks
In and around Sellindge, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

New build mastic in Sellindge
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. Typical jobs include shower seals failing in the first year or two and messy sealant that spoils new finishes, across plot handovers, show homes and skirting & floors.
In a village or hamlet like Sellindge, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Every job is covered by a one-year guarantee, wherever you are in Kent.

Questions from Sellindge
Is Sellindge in your area for new build mastic?
Yes. Our work covers London and the South East, and Sellindge is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing.
Can you help a landlord with a rental near Westenhanger station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
What does new build mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Should I go to my builder first?
If you are still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix doesn’t last, we can help.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
New build mastic around Sellindge
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Westenhanger station, the sealant around baths, showers and frames is worth checking in the first year or two.

How it works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for most snagging lists, longer for a run of plots from start to finish. For a village or hamlet like Sellindge, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Before we arrive
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive

What the job involves on each surface
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. Tell us when the home is open so we can plan around it.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Wait for the cure time before using a resealed shower
- Record problems with dated pictures
- Report sealant problems to your builder during the snagging period
- Use the extractor fan every time you shower
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.
What affects the cost of new build mastic
Jobs vary more than people expect. What affects the quote:
- The type of sealant required
- How many areas need sealing
- Mould in or behind the old joints
- Any working-time requirements on site
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The type of property
- The address or postcode of the job
- The problem you’ve noticed
- Photos by email, if that is easy
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we will talk you through the work.
