DIY sealant or a professional job?
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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
New build mastic in Bursledon, done properly
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. We work on windows & doors, bathrooms & en suites and kitchens, and the jobs we see most are leaking shower tray seals in a new home and kitchen sealant that has pulled off the wall.
For a new home in or near Bursledon, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.
There’s a 12-month guarantee on every job, whatever its size.

Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. In a smaller place like Bursledon, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Avoid scourers and strong chemicals on sealant
- Use the extractor fan every time you shower
- Get a leaking seal dealt with straight away
- Avoid running a DIY bead over the old one
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture does not sit on the sealant.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.

- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.

Advice
Your questions about new build mastic in Bursledon
Do you cover smaller places like Bursledon?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Bursledon station. Can you help?
Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Should I wait before resealing?
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.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Is there a guarantee?
Yes. All our work carries a 12-month guarantee.
Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.

New build mastic around Bursledon
Bursledon is within about 2 miles 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
