About our new build mastic in Heath End
Across Heath End, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. We work on show homes, bathrooms & en suites and skirting & floors, and common reasons people get in touch are sealant that never bonded to the surface and cracked caulk along new skirting.
Work in a small place like Heath End just needs the journey and access planning, and the work itself is the same as on any site.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Heath End: your questions answered

Can you do new build mastic in Heath End?

Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.

The process
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere like Heath End needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.

What new build mastic looks like in Heath End
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Midgham station, the sealant around baths, showers and frames is worth checking in the first year or two.

When to call us in Heath End
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
The most common problems we see are:
- Internal frame sealant that has split
- Gaps between new skirting and floors
- Second-fix sealing on new plots
- Worktop and upstand sealant coming away
In and around Heath End, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Aftercare tips
After the cure time, these simple habits help:
- Ventilate bathrooms well, especially in the first year
- Get a leaking seal dealt with right away
- Watch for new gaps as the house dries out
- Keep pictures and emails about snagging items
Watch the joints as the house settles. Small gaps can appear as the house dries.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
Different surfaces, different methods
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. We reseal them with a flexible sealant.

Why deal with it now?
DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Where a wall is exposed, as many are in small places like Heath End, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
Why us?
- Every job guaranteed for a year
- We leave the area clean and tidy
- A choice of colours where the product allows
- A sealant colour to suit the surroundings
