New build mastic in Westfield
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on skirting & floors, kitchens and show homes, and people most often call us about internal frame sealant that has split and skirting joints opening in the first winter.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
You get a one-year guarantee, the same in Westfield as everywhere else we work.

What happens if it’s left?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot and most come down to preparation. In an older home around Westfield, damp from a failed joint can get into timber and plaster.
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

Westfield questions
Can you help a landlord with a rental near Armadale station?
Yes, we work for landlords and agents. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Is Westfield in your area for new build mastic?
Yes, Westfield is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
What colour sealant will you use?
Most bathroom joints are white or clear, but other colours are available. We choose one to suit the room.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you when we finish.
Should I go to my builder first?
While the snagging or warranty period runs, the builder should be your first contact. If it isn’t sorted, or keeps failing, get in touch with us.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
What we do, step by step
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the number of plots in most cases. Around Westfield, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- 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 tricky access
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we are working on

Advice
Surface by surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
Do you need new build mastic in Westfield?
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
Common reasons people contact us are:
- Shower seals failing in the first year or two
- Smeared, uneven beads picked up at snagging
- Cracked caulk along new skirting
- Gaps opening as the house dries out and settles
Around Westfield, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- Who turns up on the day
- What preparation is included
- How hidden problems are handled
- How the colour is chosen
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Act quickly if a seal starts to leak
- Avoid scourers and strong chemicals on sealant
- Watch for new gaps as the house dries out
- Keep water off fresh sealant until it has cured
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you.
