How the job changes by surface
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing and primer used where needed.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
New build mastic in East End Green
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. We work on kitchens, show homes and bathrooms & en suites, and people most often call us about sealant work across a run of new homes and leaking shower tray seals in a new home.
For a small place like East End Green, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
All of our work is guaranteed for twelve months.

East End Green: your questions answered
Can you do new build mastic in East End Green?
Yes. Our work covers London and the South East, and East End Green is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear price.
Do you cover smaller places like East End Green?
Yes. East End Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Should I go to my builder first?
Start with the builder if you are in the snagging or warranty period. If it is not resolved, we’ll cut it out and reseal it.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or email us.
Do you work for developers?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we’ll give you a quote.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Open a window or run the fan after bathing
- Avoid running a DIY bead over the old one
- Wait for the cure time before using a resealed shower
- Don’t wait for the house to settle if water is getting through
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
Early snagging is easier snagging. Small faults turn into leaks if left over time.
When to call us in East End Green
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. As it does, timber shrinks and joints open.
If you can see any of these, it’s time to have the joints looked at:
- Joints pulling apart as timber shrinks
- Sealant work across a run of new homes
- Leaking shower tray seals in a new home
- Internal frame sealant that has split
Around East End Green, as everywhere, new build mastic is only as good as the preparation behind it.
Before you book anyone
- What guarantee comes with the work
- Are they insured?
- How the joint is cleaned and prepared
- When the joint can take water or movement
What sealant work cannot fix
We won’t take on work that will not last, so these are the limits:
- Baths and trays that move too much for sealant to cope with
- Leaks from pipes, valves or wastes, which need a plumber
- Disputes or warranty claims with your builder
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
