New build mastic in Old Dean
We work in new homes and on new-build sites across Old Dean. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. We work on show homes, skirting & floors and plot handovers, and common reasons people get in touch are second-fix sealing on new plots and new-build shower sealant that has already split.
If you’ve bought a new home in or near Old Dean, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Keep photos and emails about snagging items
- Get a leaking seal dealt with straight away
- Wait for the cure time before using a resealed shower
- Check bath and shower seals every few months as the house settles
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
Do you need new build mastic in Old Dean?
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and can tear.
The most common problems we see are:
- Plot mastic for developers ahead of handover
- Cracked sealant around new window and door frames
- Untidy sealant flagged on a snagging list
- Beads laid onto grit and dust from the build
If you’ve bought a new home near Camberley station, the sealant around baths, showers and frames is worth checking in the first year or two.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, 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.
What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. In an older home around Old Dean, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
