Advice
About our new build mastic in Cock Clarks
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. If you have worktop and upstand sealant coming away and gaps opening as the house dries out and settles, we can put it right, on show homes, bathrooms & en suites and plot handovers alike.
Work in a small place like Cock Clarks just needs the journey and access planning, and once on site, the job is the same as anywhere.
Every job is covered by our one-year guarantee, wherever you are in Essex.

What the job involves on each surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. Tell us when the home is open so we can plan around it.
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there, food-safe where it’s needed.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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 does not work out, we can still put it right.
Why deal with it now?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Older cottages and farmhouses around Cock Clarks can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and give you a clear quote before any work starts.

Common questions in Cock Clarks
Do you cover Cock Clarks for new build mastic?
Yes. Our work covers London and the South East, and Cock Clarks is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Is Cock Clarks within the area you cover?
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.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
What does new build mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Can you match the sealant colour to my new kitchen or bathroom?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
When to call us in Cock Clarks
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
Any of these means the joints need attention:
- Sealant work across a run of new homes
- Shower seals failing in the first year or two
- Cracked caulk along new skirting
- Cracks appearing as a new home settles
Around Cock Clarks, as everywhere, new build mastic is only as good as the preparation behind it.
