New build mastic in West Calder, done properly
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We work on windows & doors, bathrooms & en suites and kitchens, and people most often call us about internal frame sealant that has split and plot mastic for developers ahead of handover.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
Big or small, it’s backed by our one-year guarantee.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Put sealant faults on your snagging list early
- Don’t wait for the house to settle if water is getting through
- Wipe joints with warm soapy water
- Photograph failed sealant before it’s redone
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you.

What affects the cost of new build mastic
We do not publish a price list, because jobs vary so much. What we look at:
- Mould in or behind the old joints
- Any working-time requirements on site
- The number of rooms or windows
- The size of the job
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and send you a clear quote before any work starts.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- What’s wrong with the joints now
- The type of property
- Pictures of the joints, sent by email
- The rough size of the job
Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll take it from there.
What happens on the day
When we get to you, we check the joints match what you told us. 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. Outside jobs in West Calder need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- 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.
Preparing for the visit
- Keep children and pets away from the work area
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can

Advice
Common problems we fix in West Calder
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint.
The most common problems we see are:
- Sealant work across a run of new homes
- Cracked sealant around new window and door frames
- Leaking shower tray seals in a new home
- Skirting joints opening in the first winter
Around West Calder, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- What insurance they hold
- What guarantee comes with the work
- How the joint is cleaned and prepared
- Which colour the sealant will be
What we cannot put right
A few problems are outside what sealant work can do:
- Leaks from pipes, valves or wastes, which need a plumber
- Movement caused by a poorly fitted tray or bath
- Disputes or warranty claims with your builder
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.

Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
I let a flat near West Calder station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
How long does the job take?
As a guide, most jobs take a few hours for most snagging lists, longer for a run of plots. Bigger jobs take longer.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can you work from my snagging list?
Yes. Send the list and a few photos of the sealant items and we’ll give you a quote. We will flag anything that needs another trade.
Who should fix failed sealant in a new build?
Report it to the builder first while you are covered. Once that’s done, or if they won’t put it right, we can reseal it properly.
