New build mastic in Childrey
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first. Typical jobs include kitchen sealant that has pulled off the wall and sealant that never bonded to the surface, across show homes, bathrooms & en suites and skirting & floors.
Somewhere as small as Childrey, 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.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Why act early in Childrey
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. In a small place like Childrey, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or email us and we will give you an honest view and a quote.

What else we do in Childrey
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Keep pictures and emails about snagging items
- Put sealant faults on your snagging list early
- Use the extractor fan every time you shower
- Wipe joints with warm soapy water
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture does not sit on the sealant.
Early snagging is easier snagging. Left alone, a small crack can become a leak.
Different surfaces, different methods
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. We reseal them with a flexible sealant.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Joints and finishes in Childrey homes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Childrey questions
Is Childrey within the area you cover?
Yes, Childrey is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you do new build mastic in Childrey?
Yes. Our work covers London and the South East, and Childrey is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before any work starts.
Can I send you my snagging list?
Yes. Send us the sealant items on the list, with pictures if you can, and we’ll quote. We’ll flag anything that needs another trade.
How much does new build mastic cost in Childrey?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or send us an email and tell us what needs doing and where.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
How the visit works
There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours for most snagging lists, longer for a run of plots, including the tidy-up. In a small place like Childrey, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- 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
- Tell us about any water getting in
- Clear the area around the work
- For business premises, tell us about site rules or sign-in
Getting a quote
For a quote, call 0345 464 0079 or send us an email with the location and a short description of the problem. You’ll have a clear quote before we start.

What affects the cost of new build mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- Access and height
- The number and length of the joints
- Any mould that needs treating
- The product the joint needs
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.
Asking for a quote
To help us quote quickly, let us know:
- A few pictures by email, if you can
- Whether it’s a home or a business
- The problem you’ve noticed
- The rough size of the job
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.
When it is not the sealant
A few problems are outside what sealant work can do:
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with
- Settlement cracks that need a surveyor
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.
Surfaces we seal
- Show homes

- Smeared, uneven beads picked up at snagging
