How we handle new build mastic in Hearnden Green
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference, because that is what rushed new-build sealant normally lacks. We’re often asked to deal with cracked caulk along new skirting and leaking shower tray seals in a new home, across kitchens, show homes and bathrooms & en suites.
In a village or hamlet like Hearnden Green, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
You get a 12-month guarantee, the same in Hearnden Green as everywhere else we work.

Hearnden Green: your questions answered
Can you do new build mastic in Hearnden Green?
Yes, Hearnden Green is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
Do you work for landlords with property near Headcorn station?
Yes. We work for landlords and letting agents as well as homeowners. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do you use white or clear sealant?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We will agree it with you first.
Why does sealant fail so quickly in new builds?
It’s common, and there are normally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Can you reseal over the builder’s sealant?
No. New silicone will not bond to old silicone, so it soon lifts and traps water. We cut the old bead out completely.
How long will you be here?
That depends on the amount of work, but most jobs take anything from a few hours to several days, depending on the number of plots. We’ll give you a better idea when we quote.
When is the sealant fully cured?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
What affects the quote in Hearnden Green
We quote each job individually. This is what makes a difference:
- The product the joint needs
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- Whether the work is at height
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will go through it with you.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Roughly how big the job is
- Where the job is, and your postcode
- A few pictures by email, if you can
- If someone has resealed it before
We quote each job on its own. Just phone 0345 464 0079 or send us an email with the details.
New homes and floors in Hearnden 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.
Around Hearnden Green, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Headcorn station, the sealant around baths, showers and frames is worth checking in the first year or two.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What happens if it’s left?
The builder is generally the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. Where a wall is exposed, as many are in small places like Hearnden Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and send you a clear quote before we start.

Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and primer used where needed.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk painted or coloured to suit.
