New build mastic in Empshott
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 it isn’t put right, get in touch with us. We work on kitchens, plot handovers and bathrooms & en suites, and the jobs we see most are sealant applied over dusty or wet surfaces and cracks appearing as a new home settles.
Somewhere as small as Empshott, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Each job carries a 12-month guarantee, whatever its size.

How the visit works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots for a typical job. Somewhere as small as Empshott, access is often the only tricky part. 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.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints

What the job involves on each surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
What affects the quote in Empshott
We do not publish a price list, because no two jobs are the same. The quote depends on:
- The product the joint needs
- Whether there’s mould to deal with
- Whether the work is at height
- How much there is to do
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Pictures of the joints, sent by email
- Roughly how big the job is
- The problem you’ve noticed
- If it’s domestic, commercial or a hotel
We quote each job on its own, so start by telling us what you need. Simply ring 0345 464 0079 or email us and describe the job.
Why it’s worth doing now in Empshott
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Around Empshott, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

When to call us in Empshott
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
Signs it’s time to call us include:
- Cracked caulk along new skirting
- Shower seals failing in the first year or two
- Plot mastic for developers ahead of handover
- Sealant applied over dusty or wet surfaces
For new homes near Liss station, it’s worth checking the sealant early, while snags are still fresh.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Empshott questions
Is Empshott within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Liss station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
How do I get a quote for new build mastic in Empshott?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, before resealing.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Looking after it afterwards
After the cure time, these simple habits help:
- Avoid scourers and strong chemicals on sealant
- Keep water off fresh sealant until it has cured
- Act quickly if a seal starts to leak
- Look at the sealant regularly in the first couple of years
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
What new build mastic looks like in Empshott
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
