About our new build mastic in Giffnock
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. If you have leaking shower tray seals in a new home and sealant applied over dusty or wet surfaces, we can put it right, whatever the surface.
A lot of new homes in Scotland are timber-framed, and they settle in their first years, which can open up skirting and floor joints early on.
Every job is covered by our 12-month guarantee.

Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. Private landlords in a town like Giffnock must keep homes wind and watertight under the Repairing Standard. Replacing failed sealant early is simpler than dealing with a complaint.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

Should I try it myself first?
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.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Are you insured?
Yes. We are fully insured for every job we do.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Who should fix failed sealant in a new build?
If you’re still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix doesn’t last, we can help.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
Can you reseal over the builder’s sealant?
No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.
