New build mastic in Craigmarloch, done properly
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We work on bathrooms & en suites, show homes and plot handovers, and people most often call us about smeared, uneven beads picked up at snagging and sealant that never bonded to the surface.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What affects the quote in Craigmarloch
Every job gets its own quote. These are the things that affect it:
- Any working-time requirements on site
- Whether the work is at height
- Which sealant suits the joint
- Any mould that needs treating
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.
Helping us quote
To help us quote quickly, let us know:
- What’s wrong with the joints now
- Roughly how big the job is
- Any previous sealing or DIY work
- A few photos by email, if you can
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.
What we’re called out for in Craigmarloch
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly.
If you can see any of these, it’s time to have the joints looked at:
- Leaking shower tray seals in a new home
- Sealant work across a run of new homes
- Skirting joints opening in the first winter
- Joints pulling apart as timber shrinks
In and around Craigmarloch, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- Whether you can choose the colour
- How long the guarantee is
- When the joint can take water or movement
- Whether the sealant suits the joint
Aftercare tips
A little care helps the new joints last. We recommend:
- Do not wait for the house to settle if water is getting through
- Resist patching a failed seal with a tube from the DIY shop
- Open a window or run the fan after bathing
- Avoid scourers and strong chemicals on sealant
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents as they wear the bead.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
Joints and finishes in Craigmarloch homes
Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles. 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.
For new homes near Croy station, it’s worth checking the sealant early, while snags are still fresh.

Why it’s worth doing now in Craigmarloch
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
