How we handle new build mastic in Owslebury
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. If you’re dealing with new-build shower sealant that has already split and cracked caulk along new skirting, we can put it right, whatever the surface.
Older homes in small places like Owslebury often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Leave it or put it right?
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. You get one visit and one clear quote to plan around. Where a wall is exposed, as many are in small places like Owslebury, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

How the job changes by surface
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. We reseal them with a flexible sealant.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Watch for new gaps as the house dries out
- Resist patching a failed seal with a tube from the DIY shop
- Keep water off fresh sealant until it has cured
- Open a window or run the fan after bathing
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and protects the rest of the house.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
New build mastic around Owslebury
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Around Owslebury, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Shawford station, the sealant around baths, showers and frames is worth checking in the first year or two.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Owslebury: your questions answered
Is Owslebury within the area you cover?
Yes. Owslebury is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Shawford station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Why does sealant fail so quickly in new builds?
It’s common, and there are generally two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
My new home is still under warranty. Should I contact you?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix does not last, we can help.
Can you do plot mastic on a new development?
Yes. We work through plots to your schedule ready for handover. Tell us the plots and the joints involved and we will quote.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on the number of plots and we leave things clean and tidy. Somewhere like Owslebury needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area

Advice
What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Leaks from pipes, valves or wastes, which need a plumber
- Cracking that points to a structural problem
- A tray or bath that is not properly supported, until it’s fixed
