Covington New Build Mastic
New-build sealant joints in Covington need attention? We cut out the old, prepare the joints and apply the right sealant.
- Cracked caulk along new skirting
- Shower seals failing in the first year or two
- Second-fix sealing on new plots
How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks

Related advice
New build mastic in Covington, done properly
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. Typical jobs include cracks appearing as a new home settles and sealant work across a run of new homes, on kitchens, show homes and bathrooms & en suites.
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.
Each job carries a 12-month guarantee, large or small.

Why act early in Covington
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Why book with us
- Any old sealant cut out fully, not covered over
- We agree the colour with you first

Questions from Covington
Can you do new build mastic in Covington?
Yes, Covington is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Is Covington within the area you cover?
Yes, Covington is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
When is the best time to reseal in a new build?
Where water is getting through, do not wait. Hairline cosmetic gaps can wait until the house has settled.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
How long does the job take?
Typically it takes a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer, and we will say how long yours will take.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Resist patching a failed seal with a tube from the DIY shop
- Wipe joints with warm soapy water
- Report sealant problems to your builder during the snagging period
- Photograph failed sealant before it’s redone
Do not stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
