About our new build mastic in Plaitford Green
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you’re dealing with messy sealant that spoils new finishes and skirting joints opening in the first winter, we can help, on plot handovers, skirting & floors and show homes alike.
In a village or hamlet like Plaitford 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.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Use the extractor fan every time you shower
- Report sealant problems to your builder during the snagging period
- Check bath and shower seals every few months as the house settles
- Record problems with dated pictures
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
What happens if it’s left?
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Where a wall is exposed, as many are in small places like Plaitford Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- A tray or bath that is not properly supported, until it’s fixed
- Deciding who is responsible under a builder’s warranty
- Leaking fittings rather than failed sealant
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.

What else we do in Plaitford Green
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Plaitford Green, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- 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.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height

Do you need new build mastic in Plaitford Green?
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly.
If you can see any of these, it’s time to have the joints looked at:
- Beads laid onto grit and dust from the build
- Smeared, uneven beads picked up at snagging
- Cracked caulk along new skirting
- Cracks appearing as a new home settles
Around Plaitford Green, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- Whether you can choose the colour
- How much experience the applicator has

Plaitford Green questions
Do you cover Plaitford Green for new build mastic?
Yes, Plaitford Green is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Is Plaitford Green within the area you cover?
Yes, Plaitford Green is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or send us an email.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can you match the sealant colour to my new kitchen or bathroom?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Who should fix failed sealant in a new build?
Start with your builder while their snagging or warranty period runs. If that doesn’t work out, we’re happy to quote.
Can you do plot mastic on a new development?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.
