New build mastic in Dane Hill
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. Common call-outs are for skirting joints opening in the first winter and gaps opening as the house dries out and settles, on show homes, bathrooms & en suites and skirting & floors.
For a small place like Dane Hill, the journey and access are planned in advance, and the work itself is the same as on any site.
All our work comes with our 12-month guarantee.

Looking after it afterwards
After the cure time, these simple habits help:
- Keep photos and emails about snagging items
- Report sealant problems to your builder during the snagging period
- Follow the cure time we give you
- Do not seal over failed sealant yourself
Follow the cure time we give you before the area gets wet. Most silicones need around a day before water reaches them.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.

What we are called out for in Dane Hill
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry first.
Common reasons people contact us are:
- Sealant applied over dusty or wet surfaces
- Leaking shower tray seals in a new home
- Cracks appearing as a new home settles
- Sealant work across a run of new homes
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.

DIY versus a professional finish
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.
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.
Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Older cottages and farmhouses around Dane Hill can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
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.

How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Dane Hill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive
