About our new build mastic in Wexham Court
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. If you have second-fix sealing on new plots and untidy sealant flagged on a snagging list, we can help, on plot handovers, skirting & floors and windows & doors alike.
Older homes in small places like Wexham Court often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Surface by surface
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and prime where the product needs it.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Joints and finishes in Wexham Court homes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Get a leaking seal dealt with right away
- Avoid scourers and strong chemicals on sealant
- Open a window or run the fan after bathing
- Report sealant problems to your builder during the snagging period
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.
