New build mastic in Leverton
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. Typical jobs include internal frame sealant that has split and beads laid onto grit and dust from the build, on plot handovers, kitchens and skirting & floors.
Older homes in small places like Leverton often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. Older cottages and farmhouses around Leverton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

New build mastic in Leverton: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Leverton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Hungerford station, it’s worth checking the sealant early, while snags are still fresh.

Looking after it afterwards
After the cure time, these simple habits help:
- Wipe joints with warm soapy water
- Act quickly if a seal starts to leak
- Follow the cure time we give you
- Ventilate bathrooms well, especially in the first year
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing so moisture doesn’t sit on the sealant.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.

How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Leverton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we are working on
- Mention any parking rules near the property

FAQs for Leverton
Is Leverton in your area for new build mastic?
Yes, Leverton is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Do you work for landlords with property near Hungerford station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Is it normal for sealant to crack in a new home?
There are generally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you work for developers?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we will quote.
How long will you be here?
A typical job takes a few hours for most snagging lists, longer for a run of plots, including the preparation. We’ll confirm how long when we quote.
What affects the quote in Leverton
There’s no set price list, because no two jobs are the same. What we look at:
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
- When we can work, for business premises
- Whether there’s mould to deal with
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.
What we need to know

Landlords, agents and businesses in Leverton
We also work for property managers and facilities teams in Leverton and across West Berkshire. We can quote a run of properties together, and we’re fully insured for the work.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
When something else is needed
Sealant isn’t the answer to every problem, and we will tell you before work begins. Sealant will not put right:
- A tray or bath that isn’t properly supported, until it’s fixed
- Disputes or warranty claims with your builder
- Plumbing faults behind the sealant
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before you book.
