About our new build mastic in Newman's End
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. Typical jobs include shower seals failing in the first year or two and beads laid onto grit and dust from the build, across show homes, bathrooms & en suites and skirting & floors.
Older homes in small places like Newman's End often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
You’re covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

Do you need new build mastic in Newman's End?
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Both fail early.
The problems people usually mention when they call include:
- Internal frame sealant that has split
- Cracked caulk along new skirting
- Leaking shower tray seals in a new home
- Worktop and upstand sealant coming away
In and around Newman's End, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

If you’ve bought a new home near Sawbridgeworth station, the sealant around baths, showers and frames is worth checking in the first year or two.

How to look after the new joints
So the new joints stay in good condition:
- Record problems with dated pictures
- Keep water off fresh sealant until it has cured
- Clean sealant with mild detergent, not abrasives
- Avoid running a DIY bead over the old one
Avoid standing on the rim of the bath or the edge of the tray. Report any movement in a bath or tray.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
Questions from Newman's End
Do you cover smaller places like Newman's End?
Yes. Newman's End 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.
I let a flat near Sawbridgeworth station. Can you help?
Yes. We work for landlords and agents as well as householders. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or drop us an email.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
What colour sealant will you use?
Most bathroom joints are white or clear, but other colours are available. We choose one to suit the room and agree it with you.
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
How the visit works
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots for a typical job. For a village or hamlet like Newman's End, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
How to prepare
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks
- Clear the area around the work

What the job involves on each surface
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing.
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. We reseal them with a flexible sealant.
