About our new build mastic in Felbridge
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. If you’re dealing with sealant work across a run of new homes and leaking shower tray seals in a new home, we can put it right.
In a village or hamlet like Felbridge, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What we are called out for in Felbridge
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
Any of these means the joints need attention:
- Worktop and upstand sealant coming away
- Gaps between new skirting and floors
- Sealant applied over dusty or wet surfaces
- Smeared, uneven beads picked up at snagging
In and around Felbridge, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Surface by surface
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. A fresh flexible bead closes them.
Questions from Felbridge
Do you cover smaller places like Felbridge?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near East Grinstead station. Can you help?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can you work from my snagging list?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, before resealing.
How long does the job take?
Typically it takes anything from a few hours to several days, depending on the number of plots. Bigger jobs take longer.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
The process
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours in a single home. In a small place like Felbridge, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
