About our new build mastic in Crockerhill
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. If you have skirting joints opening in the first winter and cracked sealant around new window and door frames, we can put it right, whatever the surface.
For a small place like Crockerhill, the journey and access are planned in advance, and the work itself is the same as on any site.
Our work is backed for twelve months, in Crockerhill and everywhere else we cover.

How the job changes by surface
Windows and doors
A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Check bath and shower seals every few months as the house settles
- Photograph failed sealant before it’s redone
- Keep water off fresh sealant until it has cured
- Avoid running a DIY bead over the old one
Don’t stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.

DIY sealant or a professional job?
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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What happens if it’s left?
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. If you are unsure which you have, call 0345 464 0079 or drop us an email with pictures. In a small place like Crockerhill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Your questions about new build mastic in Crockerhill
I let a flat near Barnham station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover Crockerhill for new build mastic?

What does new build mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Why does sealant fail so quickly in new builds?
Cracking in the first couple of years is common. Poor preparation at handover adds to it.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
Will you just run a new bead over the existing one?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Do you work for developers?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
Can you do several jobs on one visit?
Yes. Just list everything you need.
What we are called out for in Crockerhill
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
Look out for any of the following:
- Leaking shower tray seals in a new home
- Cracked sealant around new window and door frames
- Second-fix sealing on new plots
- Untidy sealant flagged on a snagging list
If you’ve bought a new home near Barnham station, the sealant around baths, showers and frames is worth checking in the first year or two.

- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
