About our new build mastic in West Lavington
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you’re dealing with shower seals failing in the first year or two and skirting joints opening in the first winter, we can put it right, whatever the surface.
Somewhere as small as West Lavington, 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.
All our work is covered by a one-year guarantee.

The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Whether the job is in West Lavington itself or nearby, the right material for each joint matters as much as a neat finish.

West Lavington: your questions answered
Will you come out to West Lavington?
Yes. West Lavington is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do new build mastic in West Lavington?
Yes, West Lavington is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or send us an email.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Do you have insurance?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
When it isn’t the sealant
Before you book, it’s worth knowing the limits too:
- Movement caused by a poorly fitted tray or bath
- Cracked trays, tiles or worktops
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.

DIY sealant or a professional job?
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.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Signs you need new build mastic in West Lavington
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
It’s worth asking for a quote if you see:
- Shower seals failing in the first year or two
- Joints pulling apart as timber shrinks
- Internal frame sealant that has split
- Cracked caulk along new skirting
Around West Lavington, as everywhere, new build mastic is only as good as the preparation behind it.

How we quote for new build mastic
The quote reflects the job in front of us. We look at:
- Any working-time requirements on site
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- The number and length of the joints
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts.
What to tell us for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- If someone has resealed it before
- Pictures of the joints, sent by email
- The type of property
- Any access issues, like height or stairs
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Keep pictures and emails about snagging items
- Open a window or run the fan after bathing
- Look at the sealant regularly in the first couple of years
- Act quickly if a seal starts to leak
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
How the visit works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as West Lavington, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
How to prepare
- Clear items away from the joints we’re working on
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
