New build mastic for homes and businesses in Margaretting Tye
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. If you have internal frame sealant that has split and second-fix sealing on new plots, we can put it right, whatever the surface.
Somewhere as small as Margaretting Tye, 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.
Your job is guaranteed for a year, as with all our work.

Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Aftercare tips
After the cure time, these simple habits help:
- Raise failed sealant with the developer while you are covered
- Keep photos and emails about snagging items
- Watch for new gaps as the house dries out
- Act quickly if a seal starts to leak
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.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
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, then guaranteed for a year.
Common problems we fix in Margaretting Tye
Sealant is often one of the last jobs before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
Look out for any of the following:
- Messy sealant that spoils new finishes
- Gaps opening as the house dries out and settles
- Frame joints opening as the plaster dries
- Leaking shower tray seals in a new home
For new homes near Ingatestone station, it’s worth checking the sealant early, while snags are still fresh.

Margaretting Tye: your questions answered
I let a flat near Ingatestone station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Do you cover Margaretting Tye for new build mastic?
Yes, Margaretting Tye is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, then clean and prime the joint, before resealing.
My new home is still under warranty. Should I contact you?
While the snagging or warranty period runs, the builder should be your first contact. If it is not sorted, or keeps failing, get in touch with us.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
What information do you need?
A short description and the location, plus pictures if you have them. We’ll ask anything else we need to know.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Why deal with it now?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot and most come down to preparation. In a small place like Margaretting Tye, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What you get with us
- Any old sealant cut out fully, not covered over
- Approved under the ARBOMaster scheme
- More than 20 years in sealant work
- Neat joints and a tidy finish
