New build mastic in Bletchingdon, done properly
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you are dealing with worktop and upstand sealant coming away and sealant applied over dusty or wet surfaces, we can put it right, whatever the surface.
In a village or hamlet like Bletchingdon, 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.
Big or small, you get the same 12-month guarantee.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, 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.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Do you need new build mastic in Bletchingdon?
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
The most common problems we see are:
- Beads laid onto grit and dust from the build
- Cracked caulk along new skirting
- New-build shower sealant that has already split
- Plot mastic for developers ahead of handover
For new homes near Tackley station, it’s worth checking the sealant early, while snags are still fresh.

The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours in a single home.

- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
- Mention any tricky access

Why act early in Bletchingdon
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote to plan around. In a small place like Bletchingdon, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why book with us
- Domestic, commercial and hotel work
- We are fully insured
- 12-month guarantee on every job

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Check bath and shower seals every few months as the house settles
- Open a window or run the fan after bathing
- Keep pictures and emails about snagging items
- Report sealant problems to your builder during the snagging period
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers to help keep mould away.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
Surface by surface
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
