Why act early in Gossops Green
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. Around Gossops Green, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.

About our new build mastic in Gossops Green
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. If you have plot mastic for developers ahead of handover and kitchen sealant that has pulled off the wall, we can put it right, whatever the surface.
For a new home in or near Gossops Green, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
All of our work is guaranteed for twelve months.

What else we do in Gossops Green
What we cannot put right
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Movement caused by a poorly fitted tray or bath
- Your warranty claim itself, which is between you and the builder
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

What the job involves on each surface
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing.
For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
How to look after the new joints
To keep the joints looking good and working properly:
- Open a window or run the fan after bathing
- Wait for the cure time before using a resealed shower
- Resist patching a failed seal with a tube from the DIY shop
- Check bath and shower seals every few months as the house settles
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left in a busy bathroom.
New homes and floors in Gossops Green
Crawley, which Gossops Green is part of, is one of England’s post-war new towns. Crawley has kept growing, with newer neighbourhoods added to the original town, so brand-new homes and homes from the post-war decades sit within a short drive of each other. Older homes need their sealant and floor joints renewing, newer ones checking at snagging. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Around Gossops Green, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Ifield station, the sealant around baths, showers and frames is worth checking in the first year or two.

How it works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours in a single home. In a smaller place like Gossops Green, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Before we arrive
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed

Advice
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
