Calderwood New Build Mastic
Our applicators work in Calderwood on plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly.
- Cracked caulk along new skirting
- Joints pulling apart as timber shrinks
- Smeared, uneven beads picked up at snagging
Surface by surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out with baths filled first.
New build mastic for homes and businesses in Calderwood
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first, and if it isn’t put right, get in touch with us. Typical jobs include sealant applied over dusty or wet surfaces and sealant work across a run of new homes, on skirting & floors, kitchens and windows & doors.
For a place like Calderwood, 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.
Big or small, it’s backed by our one-year guarantee in Calderwood and across West Lothian.

Quotes for new build mastic in Calderwood
Every job gets its own quote. These are the things that affect it:
- When we can work, for business premises
- Any mould that needs treating
- How many rooms, windows or areas are involved
- The product the joint needs
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
- Any previous sealing or DIY work
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Photograph failed sealant before it’s redone
- Do not wait for the house to settle if water is getting through
- Report sealant problems to your builder during the snagging period
- Keep water off fresh sealant until it has cured
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
What happens if it’s left?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. In a place like Calderwood, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
What it costs depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
For new homes near Kirknewton station, it’s worth checking the sealant early, while snags are still fresh.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Signs you need new build mastic in Calderwood
Sealant is often one of the last jobs 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:
- Internal frame sealant that has split
- New-build shower sealant that has already split
- Sealant that never bonded to the surface
- Sealant work across a run of new homes
In and around Calderwood, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Calderwood: your questions answered
Can you help a landlord with a rental near Kirknewton 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.
Will you come out to Calderwood?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
When is the best time to reseal in a new build?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Can you work from my snagging list?
Yes. Send us the sealant items on the list, with photos if you can, and we will quote. We’ll tell you if anything on it isn’t a sealant job.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early as timber and plaster dry out. Poor preparation at handover adds to it.
What information do you need?
Tell us what needs doing and where. We’ll ask anything else we need to know.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the number of plots. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Before we arrive
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in
