New build mastic for homes and businesses in Postling Green
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you are dealing with gaps behind new kitchen upstands and shower seals failing in the first year or two, we can put it right.
In a village or hamlet like Postling Green, 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.

What we do, step by step
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for most snagging lists, longer for a run of plots in most cases. Somewhere as small as Postling Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
- Mention if the joints have been sealed before

New homes and floors in Postling Green
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

What happens if it’s left?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Where a wall is exposed, as many are in small places like Postling Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email and we will talk you through it.

Different surfaces, different methods
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
When to call us in Postling Green
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint.
People usually contact us after spotting one of these:
- Leaking shower tray seals in a new home
- Gaps behind new kitchen upstands
- Messy sealant that spoils new finishes
- Beads laid onto grit and dust from the build
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.

Postling Green: your questions answered
Is Postling Green within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do new build mastic in Postling Green?
Yes. We work across London and the South East, and Postling Green is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before we start.
Is it worth resealing while the house is still settling?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Plumbing faults behind the sealant
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before you book.
