New build mastic in West Barnham
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We work on kitchens, skirting & floors and plot handovers, and common reasons people get in touch are messy sealant that spoils new finishes and frame joints opening as the plaster dries.
Older homes in small places like West Barnham often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Joints and finishes in West Barnham homes

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep water off fresh sealant until it has cured
- Check bath and shower seals every few months as the house settles
- Clean sealant with mild detergent, not abrasives
- Don’t seal over failed sealant yourself
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
Common problems we fix in West Barnham
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
The problems people generally mention when they call are:
- Cracks appearing as a new home settles
- Cracked caulk along new skirting
- Cracked sealant around new window and door frames
- Sealant that never bonded to the surface
In and around West Barnham, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How the job changes by surface
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.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
West Barnham questions
Is West Barnham within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Barnham station?
Yes. We work for landlords and letting agents as well as homeowners. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Can you reseal over the builder’s sealant?
No. New silicone won’t bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Is the work guaranteed?
Yes. All our work carries our 12-month guarantee.
Should I try DIY first?
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.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

The process
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. For a village or hamlet like West Barnham, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.

- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can

Why it’s worth doing now in West Barnham
Small cosmetic gaps can wait for the house to settle, but water getting through cannot. If you’re unsure which you have, call 0345 464 0079 or email us with photos. Older cottages and farmhouses around West Barnham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
