New build mastic in Caulcott, done properly
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. Common call-outs are for smeared, uneven beads picked up at snagging and shower seals failing in the first year or two, across show homes, plot handovers and kitchens.
Around Caulcott, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What affects the quote in Caulcott
You’ll get a clear quote before any work starts. It’s based on:
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- Any mould that needs treating
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
Asking for a quote
When you contact us, these details help:
- A few photos by email, if you can
- Roughly how big the job is
- Any previous sealing or DIY work
- The address or postcode of the job
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.
What happens if it’s left?
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Around Caulcott, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Why Caulcott clients choose us
- Colour picked to suit the job
- We agree the colour with you first
- Sanitary silicone with an anti-fungal additive in wet areas
- Approved under the ARBOMaster scheme
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. In a small place like Caulcott, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Clear items away from the joints we’re working on
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed

Advice
When to call us in Caulcott
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.

- Gaps opening as the house dries out and settles

What new build mastic looks like in Caulcott
