How we handle new build mastic in Lower Horsebridge
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you are still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. We work on bathrooms & en suites, windows & doors and show homes, and the jobs we see most are gaps opening as the house dries out and settles and new-build shower sealant that has already split.
Somewhere as small as Lower Horsebridge, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
All of our work is guaranteed for twelve months.

When something else is needed
We will not take on work that won’t last, so here’s what sealant cannot put right:
- Cracked trays, tiles or worktops
- Leaking fittings rather than failed sealant
- Settlement cracks that need a surveyor
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

Why act early in Lower Horsebridge
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. In a small place like Lower Horsebridge, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
How long will you be here?
It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on the number of plots. We will tell you when we quote.
Why has my new-build shower seal failed already?
It’s common, and there are normally two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Different surfaces, different methods
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
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.
What we do, step by step
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before we start. Most jobs take a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Lower Horsebridge, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Clean sealant with mild detergent, not abrasives
- Report sealant problems to your builder during the snagging period
- Open a window or run the fan after bathing
- Keep water off fresh sealant until it has cured
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. Report any movement in a bath or tray.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you.
