About our new build mastic in West Clandon
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. If you’re dealing with sealant applied over dusty or wet surfaces and smeared, uneven beads picked up at snagging, we can put it right.
Older homes in small places like West Clandon often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
A 12-month guarantee comes as standard.

Why act early in West Clandon
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot. Where a wall is exposed, as many are in small places like West Clandon, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

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 call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
West Clandon questions
Is West Clandon within the area you cover?
Yes, West Clandon is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do new build mastic in West Clandon?
Yes. Our work covers London and the South East, and West Clandon is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will send you a clear quote.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Can new sealant go on top of the old bead?
No. The old sealant is cut out fully, then clean and prime the joint, before resealing.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Can I send you my snagging list?
Yes. Send us the sealant items on the list, with pictures if you can. We’ll flag anything that needs another trade.

Other services in West Clandon
Different surfaces, different methods
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Check bath and shower seals every few months as the house settles
- Do not wait for the house to settle if water is getting through
- Ventilate bathrooms well, especially in the first year
- Keep photos and emails about snagging items
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day before water reaches them.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you.
For landlords and businesses
Landlords and agents in West Clandon can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

Do you need new build mastic in West Clandon?
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints aren’t always given time to dry.
The most common problems we see are:
- Cracked sealant around new window and door frames
- Messy sealant that spoils new finishes
- Plot mastic for developers ahead of handover
- Gaps opening as the house dries out and settles
In and around West Clandon, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
