New build mastic in Mount Florida, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first. If you are dealing with shower seals failing in the first year or two and cracked caulk along new skirting, we can help.
In older Scottish city flats, floors are often timber over joists, with skirting joints that open and close with the seasons. For a flat in Mount Florida, a flexible sealant copes with that movement where filler would crack.
All our work is covered by our one-year guarantee.

What affects the cost of new build mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- The product the joint needs
- The size of the job
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
What we need to know
What to tell us when you ask for a quote:
- The rough size of the job
- Photos by email, if that’s easy
- Where the property is
- How we’d reach the joints

Landlords, agents and businesses in Mount Florida

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. 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 a tall building in Mount Florida, damp can travel a long way before it shows.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we’ll go through it with you.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid running a DIY bead over the old one
- Don’t wait for the house to settle if water is getting through
- Look at the sealant regularly in the first couple of years
- Follow the cure time we give you
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.

Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
DIY versus a professional finish
If you are 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 doesn’t work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Signs you need new build mastic in Mount Florida
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open.
The problems people normally mention when they call are:
- Beads laid onto grit and dust from the build
- Plot mastic for developers ahead of handover
- New-build shower sealant that has already split
- Cracks appearing as a new home settles
Around Mount Florida, as everywhere, new build mastic is only as good as the preparation behind it.

New build mastic in Mount Florida: local notes
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.
For new homes near Mount Florida station, it’s worth checking the sealant early, while snags are still fresh.
