New build mastic in Stambourne Green
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. We work on windows & doors, show homes and plot handovers, and the jobs we see most are joints pulling apart as timber shrinks and leaking shower tray seals in a new home.
For a small place like Stambourne Green, the journey and access are planned in advance, and the work itself is the same as on any site.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

How the job changes by surface
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
For landlords and businesses
We also work for property managers and facilities teams. Several sites can go on one quote, and we are fully insured for the work.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes a few hours in a single home. In a small place like Stambourne Green, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
How to prepare
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work

Stambourne Green questions
Do you cover smaller places like Stambourne Green?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is new build mastic in Stambourne Green guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Should I wait before resealing?
That depends on the joint. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
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. If it doesn’t work out, we can redo it.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Why has my new-build shower seal failed already?
Lots of new homes see sealant crack early. Rushed application on dusty surfaces makes it worse.
What new build mastic looks like in Stambourne Green
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For jobs in and around Stambourne Green, choosing the right material for each joint is as important as a tidy finish.

Why deal with it now?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Older cottages and farmhouses around Stambourne Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
Why us?
- Anti-fungal sanitary silicone in wet areas

Take a look at how sealant jobs are priced and customer reviews.
Do you need new build mastic in Stambourne Green?
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry.
Common reasons people contact us are:
- Sealant that never bonded to the surface
- Frame joints opening as the plaster dries
- Messy sealant that spoils new finishes
- Worktop and upstand sealant coming away
Around Stambourne Green, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- Is VAT in the price?
- Who does the work, and how experienced they are
- When the joint can take water or movement
- Whether you can choose the colour
When something else is needed
We’d rather tell you now than do work that will not last, so these are the limits:
- Plumbing faults behind the sealant
- Cracking that points to a structural problem
- Damaged fittings that need replacing
If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before booking.
Surfaces we seal
- Bathrooms & en suites

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Open a window or run the fan after bathing
- Put sealant faults on your snagging list early
- Follow the cure time we give you
- Wipe joints with warm soapy water
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it, which can damage the surface.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you.
