New build mastic in Shawlands
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. We work on skirting & floors, windows & doors and show homes, and the jobs we see most are skirting joints opening in the first winter and second-fix sealing on new plots.
In a Scottish city, commercial floors have movement joints and thresholds that wear under traffic. Those joints, and plot mastic for developers, are part of the work we cover in Shawlands.
Whatever the size of the job, you get the same 12-month guarantee in Shawlands and across Glasgow.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Wipe joints with warm soapy water
- Photograph failed sealant before it’s redone
- Open a window or run the fan after bathing
- Get a leaking seal dealt with right away
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Wind-driven rain gets into any failed joint on the outside of a city building, and in Shawlands, damp can spread through stone and plaster before anyone sees it.
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

What we are called out for in Shawlands
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
People usually contact us after spotting something like this:
- Second-fix sealing on new plots
- Cracked caulk along new skirting
- New-build shower sealant that has already split
- Cracked sealant around new window and door frames
For new homes near Shawlands station, it’s worth checking the sealant early, while snags are still fresh.

New build mastic around Shawlands
The west of Scotland is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
Different surfaces, different methods
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there suited to the job.
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
