New build mastic in Royston

Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference. We’re often asked to deal with messy sealant that spoils new finishes and sealant applied over dusty or wet surfaces, across windows & doors, show homes and bathrooms & en suites.

In older Scottish city flats, floors are often timber over joists, so skirting joints open and close through the year. For a flat in Royston, a flexible sealant copes with that movement where filler would crack.

Big or small, you get the same 12-month guarantee in Royston and across Glasgow.

Joints and finishes in Royston homes

The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.

In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

What we’re called out for in Royston

A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.

People generally contact us when they notice something like this:

  • Skirting joints opening in the first winter
  • Gaps behind new kitchen upstands
  • Gaps opening as the house dries out and settles
  • Sealant work across a run of new homes

In and around Royston, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Choosing a sealant specialist

DIY versus a professional finish

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Some sealant jobs are within reach of a careful DIYer, 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.

Keeping the joints in good condition

A little care helps the new joints last. We recommend:

  • Keep pictures and emails about snagging items
  • Report sealant problems to your builder during the snagging period
  • Ventilate bathrooms well, especially in the first year
  • Keep water off fresh sealant until it has cured

Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents.

Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.

Honest limits

Before booking, it’s worth knowing the limits too:

  • Baths and trays that move too much for sealant to cope with
  • Leaking fittings rather than failed sealant
  • Cracking that points to a structural problem

If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
