Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time. Homes in smaller places like Shinfield can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

- Over 20 years’ experience
- Neat joints and a tidy finish

What we are called out for in Shinfield
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
People generally contact us when they notice something like this:
- Cracked sealant around new window and door frames
- Gaps between new skirting and floors
- Smeared, uneven beads picked up at snagging
- Kitchen sealant that has pulled off the wall
If you’ve bought a new home near Reading Green Park station, the sealant around baths, showers and frames is worth checking in the first year or two.

Advice
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Do you guarantee your work?

Why has my new-build shower seal failed already?
It’s common, and there are normally two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
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.
Will you just run a new bead over the existing one?
No. We always remove the existing bead, then clean and prime the joint, and a new bead applied.
