New build mastic in Lower Caversham, done properly
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We work on show homes, plot handovers and kitchens, and people most often call us about worktop and upstand sealant coming away and messy sealant that spoils new finishes.
In and around Lower Caversham, floors range from older timber boards to tiles and newer finishes, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
Whatever the size of the job, it’s backed by our one-year guarantee.

Can I do it myself?
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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
New homes and floors in Lower Caversham
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Reading station, the sealant around baths, showers and frames is worth checking in the first year or two.

Advice
Common problems we fix in Lower Caversham
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.
Signs it’s time to call us include:
- Gaps behind new kitchen upstands
- Smeared, uneven beads picked up at snagging
- Plot mastic for developers ahead of handover
- Skirting joints opening in the first winter
In and around Lower Caversham, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- Whether VAT is included
- When the joint can take water or movement
- How much experience the applicator has
- Which sealant they’ll use, and why
Why it’s worth doing now in Lower Caversham
Small cosmetic gaps can wait for the house to settle, but water getting through cannot. Not sure whether yours can wait? You can phone 0345 464 0079 or send us an email with a few photos. In an older home around Lower Caversham, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
