About our new build mastic in Oxnam
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. Common call-outs are for plot mastic for developers ahead of handover and cracked caulk along new skirting, across kitchens, plot handovers and bathrooms & en suites.
For a place like Oxnam, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
The work is covered for a year after we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

What happens if it’s left?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.

How it works
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take anything from a few hours to several days, depending on the number of plots. Outside jobs in Oxnam need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- 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.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before

For jobs in and around Oxnam, choosing the right material for each joint is as important as a tidy finish.

Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- A tray or bath that is not properly supported, until it’s fixed
- Cracked trays, tiles or worktops
- Structural cracks in walls or ceilings
