How we handle new build mastic in Furzeley Corner
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 have untidy sealant flagged on a snagging list and cracked caulk along new skirting, we can help, whatever the surface.
Somewhere as small as Furzeley Corner, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we will explain what it covers.

Common questions in Furzeley Corner
Can you help a landlord with a rental near Cosham station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Will you come out to Furzeley Corner?
Yes, Furzeley Corner is covered. 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.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
My new home is still under warranty. Should I contact you?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.
Why does sealant fail so quickly in new builds?
There are generally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Record problems with dated pictures
- Avoid scourers and strong chemicals on sealant
- Raise failed sealant with the developer while you’re covered
- Do not wait for the house to settle if water is getting through
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers to help keep mould away.
Early snagging is easier snagging. Small faults turn into leaks if left over time.
How it works
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes anything from a few hours to several days, depending on the number of plots for a typical job. In a small place like Furzeley Corner, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
How to get a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What new build mastic looks like in Furzeley Corner
Furzeley Corner is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth 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.
If you’ve bought a new home near Cosham station, the sealant around baths, showers and frames is worth checking in the first year or two.

Surface by surface
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
Signs you need new build mastic in Furzeley Corner
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
It’s worth asking for a quote if you see:
- Gaps behind new kitchen upstands
- Smeared, uneven beads picked up at snagging
- Frame joints opening as the plaster dries
- Sealant work across a run of new homes
In and around Furzeley Corner, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
