Rotherfield: your questions answered
Will you come out to Rotherfield?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Rotherfield in your area for new build mastic?
Yes, Rotherfield is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Are you insured?
Yes, we are fully insured for every job we do.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Can you match the sealant colour to my new kitchen or bathroom?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
New build mastic for homes and businesses in Rotherfield
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. Typical jobs include gaps opening as the house dries out and settles and internal frame sealant that has split, across windows & doors, kitchens and plot handovers.
In a village or hamlet like Rotherfield, 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.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Honest limits
Sealant is not the answer to every problem, and we will tell you before work begins. It won’t solve:
- Leaks from pipes, valves or wastes, which need a plumber
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with

Keeping the joints in good condition
After the cure time, these simple habits help:
- Act quickly if a seal starts to leak
- Watch for new gaps as the house dries out
- Wait for the cure time before using a resealed shower
- Put sealant faults on your snagging list early
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.

When to call us in Rotherfield
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
If you can see any of these, it’s time to have the joints looked at:
- Leaking shower tray seals in a new home
- Cracked sealant around new window and door frames
- Cracks appearing as a new home settles
- Beads laid onto grit and dust from the build
In and around Rotherfield, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Can I do it myself?
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.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
