About our new build mastic in Lower Largo
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We’re often asked to deal with untidy sealant flagged on a snagging list and kitchen sealant that has pulled off the wall, on windows & doors, bathrooms & en suites and kitchens.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
We stand behind the work with a 12-month guarantee.

Common problems we fix in Lower Largo
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Most people get in touch when they notice something like this:
- Joints pulling apart as timber shrinks
- Internal frame sealant that has split
- Untidy sealant flagged on a snagging list
- Cracked caulk along new skirting
In and around Lower Largo, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- What preparation is included
- What the cure time is
- Is the old sealant removed completely?
- How hidden problems are handled
Can I do it myself?
If you do try it yourself, take your time over the 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.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Why it’s worth doing now in Lower Largo
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time and most come down to preparation. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

New build mastic in Lower Largo: local notes
Lower Largo is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
For new homes near Leven station, it’s worth checking the sealant early, while snags are still fresh.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Follow the cure time we give you
- Watch for new gaps as the house dries out
- Record problems with dated pictures
- Don’t seal over failed sealant yourself
Leave the sealant for the cure time we give you before showering or bathing. Silicone is generally left for about a day.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
What we do, step by step
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes a few hours for most snagging lists, longer for a run of plots in most cases. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
How to get a quote
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand.
