About our new build mastic in Rough Common
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. Common call-outs are for shower seals failing in the first year or two and gaps opening as the house dries out and settles, across show homes, windows & doors and plot handovers.
Older homes in small places like Rough Common often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Our work is backed for twelve months, in Rough Common and everywhere else we cover.

New homes and floors in Rough Common

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Look at the sealant regularly in the first couple of years
- Avoid scourers and strong chemicals on sealant
- Follow the cure time we give you
- Don’t wait for the house to settle if water is getting through
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day to cure enough for use.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Different surfaces, different methods
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
Landlords, agents and businesses in Rough Common
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Why act early in Rough Common
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Where a wall is exposed, as many are in small places like Rough Common, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit is normally more efficient than separate visits. You’ll get one clear quote for the whole job.

What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Rough Common, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- On commercial sites, let us know about site rules
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts
