When to call us in Penicuik

People generally contact us when they notice one of these:
- Joints pulling apart as timber shrinks
- Gaps behind new kitchen upstands
- Sealant applied over dusty or wet surfaces
- Sealant work across a run of new homes
In and around Penicuik, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

About our new build mastic in Penicuik
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference. Typical jobs include internal frame sealant that has split and joints pulling apart as timber shrinks, across kitchens, show homes and skirting & floors.
A lot of new homes in Scotland are timber-framed, and they settle in their first years, which can open up skirting and floor joints early on.
All our work comes with a one-year guarantee.

For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Looking after it afterwards
So the new joints stay in good condition:
- Record problems with dated photos
- Follow the cure time we give you
- Ventilate bathrooms well, especially in the first year
- Act quickly if a seal starts to leak
Do not stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Leave it or put it right?
A hairline gap at a skirting can wait, but a leaking seal can’t. Not sure whether yours can wait? You can send an email to info@mrmastic.co.uk with a few photos. In flats with a shared stair in Penicuik, a leak from a failed seal can affect the flat below too, which turns a small job into a bigger one.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
