FAQs for Penilee
Is there a guarantee on new build mastic in Penilee?
All our work, in Penilee and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
I let a flat near Hillington West station. Can you help?
Yes. We work for landlords and agents as well as householders. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Is it normal for sealant to crack in a new home?
It’s common, and there are usually two reasons: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
How long does the job take?
A typical job takes a few hours in a single home. We’ll confirm how long when we quote.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Do you cover Penilee?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes Penilee.
Can you work from my snagging list?
Yes. Send it with photos and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
How we handle new build mastic in Penilee
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. We are often asked to deal with cracked caulk along new skirting and plot mastic for developers ahead of handover, across show homes, windows & doors and kitchens.
In older Scottish city flats, floors are often timber over joists, with skirting joints that open and close with the seasons. In Penilee, a flexible sealant suits those joints better than filler.
Your job is guaranteed for a year, as with all our work.

Leave it or put it right?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. In a tenement flat in Penilee, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
Why us?
- We never seal over old sealant
- 20+ years of sealant experience

Signs you need new build mastic in Penilee
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
It’s worth asking for a quote if you see:
- Skirting joints opening in the first winter
- Second-fix sealing on new plots
- Sealant applied over dusty or wet surfaces
- Frame joints opening as the plaster dries
For new homes near Hillington West station, it’s worth checking the sealant early, while snags are still fresh.
Before you book anyone
- Who turns up on the day
- Which sealant they’ll use, and why
- How the colour is chosen
- What preparation is included
How to look after the new joints
To keep the joints looking good and working properly:
- Look at the sealant regularly in the first couple of years
- Keep water off fresh sealant until it has cured
- Put sealant faults on your snagging list early
- Get a leaking seal dealt with right away
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.

Surface by surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will give you a quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
New build mastic in Penilee: 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.
In and around Penilee, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
