New build mastic in Cripp's Corner, done properly
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. Common call-outs are for sealant that never bonded to the surface and shower seals failing in the first year or two, across show homes, skirting & floors and windows & doors.
Older homes in small places like Cripp's Corner often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Our work is backed for twelve months, in Cripp's Corner and everywhere else we cover.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
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.
How we quote for new build mastic
Jobs vary more than people expect. The main factors:
- Whether there’s mould to deal with

Asking for a quote
Photos by email are helpful but not essential. Please mention:

- How we’d reach the joints

What we’re called out for in Cripp's Corner
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Any of these means the joints need attention:
- Gaps behind new kitchen upstands
- Gaps opening as the house dries out and settles
- Sealant applied over dusty or wet surfaces
- Untidy sealant flagged on a snagging list
Around Cripp's Corner, as everywhere, new build mastic is only as good as the preparation behind it.
What to look for in a quote
- Whether they seal over old material or remove it
- What insurance they hold
- How long to leave it before use
- How the surfaces are prepared before sealing

FAQs for Cripp's Corner
Do you cover smaller places like Cripp's Corner?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Robertsbridge station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.
Should I go to my builder first?
Your builder, if you are still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme, room by room. Get in touch with the number of plots and the scope for a clear quote.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints.
Can new sealant go on top of the old bead?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little.
Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Where a wall is exposed, as many are in small places like Cripp's Corner, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.
