New build mastic in Lower Common
Across Lower Common, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. We work on skirting & floors, show homes and windows & doors, and people most often call us about internal frame sealant that has split and cracked caulk along new skirting.
In a village or hamlet like Lower Common, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
You get a 12-month guarantee, the same in Lower Common as everywhere else we work.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Why deal with it now?
A hairline gap at a skirting can wait, but water getting through can’t. If you are unsure which you have, ring 0345 464 0079 or send us an email with photos and we will give you a straight answer. In a small place like Lower Common, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Don’t wait for the house to settle if water is getting through
- Report sealant problems to your builder during the snagging period
- Record problems with dated photos
- Do not seal over failed sealant yourself
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture does not sit on the sealant.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
When something else is needed
Sealant isn’t the answer to every problem, and we’ll tell you before any work starts. Sealant won’t put right:
- Damaged fittings that need replacing
- Leaks from pipes, valves or wastes, which need a plumber
- Baths and trays that move too much for sealant to cope with
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

Different surfaces, different methods
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
