About our new build mastic in Lillingstone Lovell
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. If you have joints pulling apart as timber shrinks and cracked caulk along new skirting, we can put it right, whatever the surface.
In a village or hamlet like Lillingstone Lovell, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Wipe joints with warm soapy water
- Watch for new gaps as the house dries out
- Do not seal over failed sealant yourself
- Keep pictures and emails about snagging items
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
What happens if it’s left?
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Where a wall is exposed, as many are in small places like Lillingstone Lovell, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Questions from Lillingstone Lovell
Is there a guarantee on new build mastic in Lillingstone Lovell?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is Lillingstone Lovell in your area for new build mastic?
Yes, Lillingstone Lovell is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Why does sealant fail so quickly in new builds?
Cracking in the first couple of years is common as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Lillingstone Lovell and the rest of Buckinghamshire, along with the rest of our area.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before any work starts.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home and we leave things clean and tidy. In a small place like Lillingstone Lovell, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
How to prepare
- Clear the area around the work
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises

What the job involves on each surface
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there suited to the job.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
