How we handle new build mastic in Wanlockhead
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We work on kitchens, skirting & floors and windows & doors, and the jobs we see most are cracked sealant around new window and door frames and new-build shower sealant that has already split.
For a place like Wanlockhead, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

Why act early in Wanlockhead
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. In an older home around Wanlockhead, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

What we are called out for in Wanlockhead
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
People usually contact us after spotting one of these:
- Untidy sealant flagged on a snagging list
- Skirting joints opening in the first winter
- Frame joints opening as the plaster dries
- Plot mastic for developers ahead of handover
In and around Wanlockhead, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Common questions in Wanlockhead
What guarantee comes with new build mastic in Wanlockhead?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Is Wanlockhead within the area you cover?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then send an email to info@mrmastic.co.uk.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but sealant comes in other colours too. We match the colour to the finish before we begin.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Are you insured?
Yes. We’re fully insured.
How long before the joint can be used?
Cure times vary by product. Before we leave, we’ll tell you the cure time.
How the visit works
On the day, we start by going over the job with you. We protect the surfaces around the joints before work begins. The work usually takes a few hours for most snagging lists, longer for a run of plots. Around Wanlockhead, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Before we arrive
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Avoid running a DIY bead over the old one
- Do not wait for the house to settle if water is getting through
- Raise failed sealant with the developer while you are covered
- Ventilate bathrooms well, especially in the first year
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
When something else is needed
A few problems are outside what sealant work can do:
- Deciding who is responsible under a builder’s warranty
- Leaks from pipes, valves or wastes, which need a plumber
- Movement caused by a poorly fitted tray or bath
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before booking.
