New build mastic in Atherfield Green, done properly
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. If you are dealing with skirting joints opening in the first winter and messy sealant that spoils new finishes, we can put it right, on show homes, plot handovers and bathrooms & en suites alike.
In a village or hamlet like Atherfield Green, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
A one-year guarantee comes as standard.

Your questions about new build mastic in Atherfield Green
Can you do new build mastic in Atherfield Green?
Yes. Our work covers London and the South East, and Atherfield Green is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Is Atherfield Green within the area you cover?
Yes, Atherfield Green is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for developers?
Yes. We seal plots to the developer’s programme ready for handover. Get in touch with the number of plots and the scope and we will quote.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
Where do you work from?
We work from Crawley. We cover Atherfield Green and the rest of the Isle of Wight, along with the rest of our area.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Can you reseal over the builder’s sealant?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
Should I wait before resealing?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
The process
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. The job generally takes a few hours in a single home. Somewhere as small as Atherfield Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Tell us about any water getting in
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in

Do you need new build mastic in Atherfield Green?
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
These are the problems we are asked about most:
- Joints pulling apart as timber shrinks
- Worktop and upstand sealant coming away
- Cracked sealant around new window and door frames
- Second-fix sealing on new plots
For jobs in and around Atherfield Green, choosing the right material for each joint is as important as a tidy finish.
What to look for in a quote
- Whether you can choose the colour
- Is the old sealant removed completely?
- Whether the sealant suits the joint
- How the joint is cleaned and prepared
Honest limits
New sealant cannot fix everything, and we’ll tell you before any work starts. It will not solve:
- Leaks from pipes, valves or wastes, which need a plumber
- Baths and trays that move too much for sealant to cope with
- Settlement cracks that need a surveyor
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

What affects the quote in Atherfield Green
We quote each job individually. This is what makes a difference:
- The number and length of the joints
- When we can work, for business premises
- The product the joint needs
- How many areas need sealing
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- Where the job is, and your postcode
- A few pictures by email, if you can
- Any access issues, like height or stairs
- The type of property
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.

Different surfaces, different methods
Show homes
We seal show-home bathrooms, kitchens and frames ready for viewings. We will plan around viewing times.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it in a colour to suit.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Resist patching a failed seal with a tube from the DIY shop
- Follow the cure time we give you
- Check bath and shower seals every few months as the house settles
- Get a leaking seal dealt with right away
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
New build mastic around Atherfield Green
Atherfield Green is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Atherfield Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
