- Leaking shower tray seals in a new home
- Cracks appearing as a new home settles
- Worktop and upstand sealant coming away
How to look after the new joints
Aftercare is simple:
- Get a leaking seal dealt with right away
- Wipe joints with warm soapy water
- Keep water off fresh sealant until it has cured
- Open a window or run the fan after bathing
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day before water reaches them.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
About our new build mastic in Lochboisdale
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We are often asked to deal with cracked caulk along new skirting and kitchen sealant that has pulled off the wall, on plot handovers, bathrooms & en suites and windows & doors.
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.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

New build mastic in Lochboisdale: local notes
Lochboisdale is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
In and around Lochboisdale, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Lochboisdale is in Na h-Eileanan Siar. Anywhere in HS8, we cover new build mastic for homes and businesses. Lochboisdale is one of 87 places in Na h-Eileanan Siar where we work for new build mastic.
Our applicators cover all of the HS8 postcode area for new build mastic and the streets around it. We cover properties on Braehead, Calabhaigh and Kenneth Terrace. Close by, we work in Loch Baghasdail (1 mile north), Dalabrog (2 miles north-west), Rubha Ban (5 miles south), Eòlaigearraidh (9 miles south-west) and Cuidhir (12 miles south-west).

Landmarks near Lochboisdale
Nearby you will also find Calvay Castle (1.8 miles east). Not far away are Beinn Ruigh Choinnich and Loch Stulaval.
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Signs you need new build mastic in Lochboisdale
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry before the sealant goes on.
It’s worth asking for a quote if you see:
- Shower seals failing in the first year or two
- Cracked caulk along new skirting
- Sealant work across a run of new homes
- Sealant applied over dusty or wet surfaces
Whether the job is in Lochboisdale itself or nearby, the right material for each joint matters as much as a neat finish.
Before booking anyone
- Are they insured?
- Is the old sealant removed completely?
- What product goes in the joint
- How much experience the applicator has
Surface by surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it in a colour to suit.
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Why it’s worth doing now in Lochboisdale
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote. In a place like Lochboisdale, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.

Lochboisdale: your questions answered
Can you do new build mastic in Lochboisdale?
Yes. We work across all of Scotland, and Lochboisdale is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Do you cover smaller places like Lochboisdale?
Yes, we do. Our work covers the whole of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before work begins.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply drop us a line at info@mrmastic.co.uk.
Are you insured?
Yes. Full insurance covers our work.
