New build mastic in Lambs Green, done properly
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. If you are dealing with kitchen sealant that has pulled off the wall and new-build shower sealant that has already split, we can put it right, on skirting & floors, show homes and plot handovers alike.
For a small place like Lambs Green, the journey and access are planned in advance, and the work itself is the same as on any site.
Big or small, you get the same 12-month guarantee in Lambs Green and across West Sussex.

Signs you need new build mastic in Lambs Green
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.
Any of these means the joints need attention:
- New-build shower sealant that has already split
- Beads laid onto grit and dust from the build
- Smeared, uneven beads picked up at snagging
- Plot mastic for developers ahead of handover
If you’ve bought a new home near Faygate station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before booking anyone
- Are they insured?
- The length of the guarantee
- How the surfaces are prepared before sealing
- Whether they seal over old material or remove it
Why deal with it now?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time. Around Lambs Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is generally more efficient than separate visits. We’ll give you a clear price for the lot.

How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Lambs Green 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 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.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we are working on

Questions from Lambs Green
Do you work for landlords with property near Faygate station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Is Lambs Green within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
How long before the joint can be used?
It depends on the product and the temperature. Before we leave, we will tell you the cure time.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Get a leaking seal dealt with right away
- Watch for new gaps as the house dries out
- Keep water off fresh sealant until it has cured
- Avoid scourers and strong chemicals on sealant
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
