What new build mastic looks like in Clifton Hampden

Why it’s worth doing now in Clifton Hampden
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. Older cottages and farmhouses around Clifton Hampden can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

What else we do in Clifton Hampden
How to look after the new joints
Looking after new joints is easy:
- Act quickly if a seal starts to leak
- Report sealant problems to your builder during the snagging period
- Resist patching a failed seal with a tube from the DIY shop
- Photograph failed sealant before it’s redone
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
Early snagging is easier snagging. Left alone, a small crack can become a leak.
What the job involves on each surface
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing to keep callbacks down.
Common questions in Clifton Hampden
I let a flat near Culham station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Is Clifton Hampden in your area for new build mastic?
Yes. We work across London and the South East, and Clifton Hampden is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
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.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Why does sealant fail so quickly in new builds?
It’s common, and there are generally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Can new sealant go on top of the old bead?
No. New silicone won’t bond to old silicone, so it soon lifts and traps water. We cut the old bead out completely.
Do you use white or clear sealant?
White and clear are the most common, but other colours are available. We choose one to suit the room and agree it with you.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- A tray or bath that isn’t properly supported, until it’s fixed
- Your warranty claim itself, which is between you and the builder
- Plumbing faults behind the sealant
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.

Related advice
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
