New-build mastic & snagging in Shippon, Oxfordshire
New-build sealant joints in Shippon need attention? We cut out the old, prepare the joints and apply the right sealant.
- Internal frame sealant that has split
- Gaps between new skirting and floors
- Beads laid onto grit and dust from the build
New build mastic in Shippon, done properly
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. If you’re dealing with plot mastic for developers ahead of handover and messy sealant that spoils new finishes, we can help, on windows & doors, show homes and kitchens alike.
Around Shippon, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run of plots. Somewhere like Shippon needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at why each joint failed, including any movement.
- 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.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts

Advice
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:

- Structural cracks in walls or ceilings
- Deciding who is responsible under a builder’s warranty

What else we do in Shippon
How the job changes by surface
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one that suits the frame.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing.
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What new build mastic looks like in Shippon
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Is there any odour?

Who should fix failed sealant in a new build?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it.
I rent my home. Can I book you?

Can I send you my snagging list?
Yes. Send us the sealant items on the list, with pictures if you can, and we will quote. We’ll tell you if anything on it is not a sealant job.
What does new build mastic cost?

Common problems we fix in Shippon
Sealant applied onto damp surfaces does not bond well. Site programmes don’t always leave time for joints to dry first.
The most common problems we see are:
- Shower seals failing in the first year or two
- Frame joints opening as the plaster dries
- Plot mastic for developers ahead of handover
- Gaps opening as the house dries out and settles
If you’ve bought a new home near Radley station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before booking
- What preparation is included
- Whether all the old sealant comes out first
- What happens if they find a problem under the old sealant
- Who does the work, and how experienced they are
