How we handle new build mastic in Westwell Leacon
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. We’re often asked to deal with sealant that never bonded to the surface and gaps between new skirting and floors, across skirting & floors, windows & doors and bathrooms & en suites.
In a village or hamlet like Westwell Leacon, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Big or small, it’s backed by our one-year guarantee.

Your questions about new build mastic in Westwell Leacon
Is Westwell Leacon in your area for new build mastic?
Yes. We work across London and the South East, and Westwell Leacon is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
Will you come out to Westwell Leacon?
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.
Why has my new-build shower seal failed already?
There are generally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient.
Where is Mr Mastic based?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Resist patching a failed seal with a tube from the DIY shop
- Wait for the cure time before using a resealed shower
- Wipe joints with warm soapy water
- Keep pictures and emails about snagging items
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Settlement cracks that need a surveyor
- Plumbing faults behind the sealant
- Your warranty claim itself, which is between you and the builder
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.

What we are called out for in Westwell Leacon
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.
The problems people generally mention when they call include:
- Internal frame sealant that has split
- New-build shower sealant that has already split
- Sealant that never bonded to the surface
- Untidy sealant flagged on a snagging list
In and around Westwell Leacon, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- What happens if the job turns out different
- How the surfaces are prepared before sealing
- What the cure time is
- What insurance they hold
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, 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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What the job involves on each surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
Landlords, agents and businesses in Westwell Leacon
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we are fully insured for the work.
How it 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 a few hours for most snagging lists, longer for a run of plots. Somewhere like Westwell Leacon 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.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before
