Signs you need new build mastic in New Cumnock

The problems people generally mention when they call are:
- Internal frame sealant that has split
- Untidy sealant flagged on a snagging list
- Gaps behind new kitchen upstands
- Sealant work across a run of new homes
For new homes near New Cumnock station, it’s worth checking the sealant early, while snags are still fresh.

New build mastic for homes and businesses in New Cumnock
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you have joints pulling apart as timber shrinks and internal frame sealant that has split, we can help, whatever the surface.
Around smaller Scottish places like New Cumnock, new homes tend to be single plots or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What else we do in New Cumnock
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What new build mastic looks like in New Cumnock
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles. 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.
In and around New Cumnock, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
New Cumnock is about 18 miles east of Ayr, in East Ayrshire. Jobs in New Cumnock get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. New Cumnock is one of 53 towns and villages in East Ayrshire where we work for new build mastic. Glasgow is on our list too, about 32 miles from New Cumnock.

Work for landlords, hotels and businesses
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to several days, depending on the number of plots from start to finish. Outdoor work around New Cumnock depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. 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.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules

What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’ll tell you before any work starts. Sealant will not put right:
- Deciding who is responsible under a builder’s warranty
- Leaking fittings rather than failed sealant
- Settlement cracks that need a surveyor
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
Surfaces we seal
- Skirting & floors
- Windows & doors
- Bathrooms & en suites
- Kitchens
- Show homes
- Plot handovers
What the job involves on each surface
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens.
