How we handle new build mastic in South Stoke
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a seal that’s letting water through needs doing now. We work on skirting & floors, plot handovers and kitchens, and common reasons people get in touch are sealant applied over dusty or wet surfaces and internal frame sealant that has split.
Around South Stoke, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
You’re covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

How we quote for new build mastic
We don’t publish a price list, because jobs vary so much. What we look at:
- The type of sealant required
- How much old sealant there is and how hard it is to remove
- Access and height
- Mould in or behind the old joints
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
What we need to know
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- Photos by email, if that is easy
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
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, and email photos if that’s easy.
Surface by surface
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out with baths filled first.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Wait for the cure time before using a resealed shower
- Put sealant faults on your snagging list early
- Do not wait for the house to settle if water is getting through
- Resist patching a failed seal with a tube from the DIY shop
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
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.

I let a flat near Cholsey station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.

Yes. South Stoke is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.

What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
How long does new build mastic take?
Most jobs take a few hours in a single home. Your quote will say how long we expect yours to take.
Do you need new build mastic in South Stoke?
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 can tear.
It’s worth asking for a quote if you see:
- Cracked sealant around new window and door frames
- Shower seals failing in the first year or two
- Skirting joints opening in the first winter
- Second-fix sealing on new plots
For new homes near Cholsey station, it’s worth checking the sealant early, while snags are still fresh.

How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours in a single home. Somewhere like South Stoke needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can

Advice
Also in South Stoke
Why deal with it now?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Around South Stoke, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Why book with us
- Over 20 years’ experience
- Experience in homes, commercial sites and hotels
- White, clear, grey or coloured to suit, where the product allows
- A sealant colour to suit the surroundings
