Fritwell New Build Mastic
New-build sealant joints in Fritwell need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Joints pulling apart as timber shrinks
- Sealant that never bonded to the surface
- Messy sealant that spoils new finishes
How we handle new build mastic in Fritwell
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. We work on plot handovers, kitchens and bathrooms & en suites, and common reasons people get in touch are shower seals failing in the first year or two and joints pulling apart as timber shrinks.
Older homes in small places like Fritwell often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Look at the sealant regularly in the first couple of years
- Don’t seal over failed sealant yourself
- Put sealant faults on your snagging list early
- Act quickly if a seal starts to leak
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
When to call us in Fritwell
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that cannot keep up splits.
Most people get in touch when they notice one of these:
- Plot mastic for developers ahead of handover
- Leaking shower tray seals in a new home
- Worktop and upstand sealant coming away
- Messy sealant that spoils new finishes
If you’ve bought a new home near Heyford station, the sealant around baths, showers and frames is worth checking in the first year or two.

What happens on the day
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Fritwell, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Before we arrive
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in

Advice
Can I do it myself?
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.
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.
