New build mastic in Westfield
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. We’re often asked to deal with worktop and upstand sealant coming away and beads laid onto grit and dust from the build, on bathrooms & en suites, kitchens and plot handovers.
Work in a place like Westfield is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
Our work is backed for twelve months.

What we are called out for in Westfield
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that can’t keep up splits.
Common reasons people contact us include:
- Sealant applied over dusty or wet surfaces
- Sealant work across a run of new homes
- Cracks appearing as a new home settles
- Frame joints opening as the plaster dries
In and around Westfield, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Why deal with it now?
A hairline gap at a skirting can wait, but a leaking seal can’t. If you’re unsure which you have, send an email to info@mrmastic.co.uk with photos and we’ll tell you. Around Westfield, water from a failed joint in an older stone home can soak into timber and plaster.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

What new build mastic looks like in Westfield
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. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
If you’ve bought a new home near Croy station, the sealant around baths, showers and frames is worth checking in the first year or two.

How we quote for new build mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- How easy the joints are to reach
- Which sealant suits the joint
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.
Asking for a quote
To help us quote quickly, please include:
- Any previous sealing or DIY work
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.

What we can’t put right
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Your warranty claim itself, which is between you and the builder
- Leaking fittings rather than failed sealant
- Baths and trays that move too much for sealant to cope with
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before you book.
Surfaces we seal

Is Westfield in your area for new build mastic?
Yes, Westfield is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we will send you a clear quote.
Can you help a landlord with a rental near Croy station?

Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme. Get in touch with the number of plots and the scope for a clear quote.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
My new home is still under warranty. Should I contact you?
While the snagging or warranty period runs, the builder should be your first contact. If it is not sorted, or keeps failing, get in touch with us.
Do you use white or clear sealant?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
