How we handle new build mastic in Hareplain
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. Typical jobs include joints pulling apart as timber shrinks and leaking shower tray seals in a new home, on plot handovers, kitchens and bathrooms & en suites.
In a village or hamlet like Hareplain, 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.
Each job carries a 12-month guarantee, whatever its size.

Advice
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Hareplain: your questions answered
Can you help a landlord with a rental near Headcorn station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Is Hareplain within the area you cover?
Yes. Hareplain is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can you match the sealant colour to my new kitchen or bathroom?
White and clear are the most common, but sealant comes in other colours too. We choose one to suit the room and agree it with you.
What information do you need?
Tell us what needs doing and where, with photos by email if possible. We’ll ask anything else we need to know.
How do I get a quote for new build mastic in Hareplain?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Surface by surface
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and prime where the product needs it.
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there.

What else we do in Hareplain
What we are called out for in Hareplain
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
Most people get in touch after spotting one of these:
- Skirting joints opening in the first winter
- Cracked sealant around new window and door frames
- Beads laid onto grit and dust from the build
- Cracks appearing as a new home settles
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.

For landlords and businesses
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured.

When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Settlement cracks that need a surveyor
- Your warranty claim itself, which is between you and the builder
- Plumbing faults behind the sealant
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.
