The price is agreed before any work begins. It takes into account:

  • Any working-time requirements on site
  • The type of sealant required

New build mastic in Allanton, done properly

We never seal over a failed new-build bead. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. We’re often asked to deal with beads laid onto grit and dust from the build and kitchen sealant that has pulled off the wall, across windows & doors, kitchens and bathrooms & en suites.

For a place like Allanton, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.

Big or small, you get the same 12-month guarantee.

Different surfaces, different methods

Show homes

Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.

Plot handovers

Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed.

What we do, step by step

You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for most snagging lists, longer for a run of plots for a typical job. Outside jobs in Allanton 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.

  1. First we work through your snagging list or plot schedule with you.
  2. Failed or untidy sealant is cut out completely.
  3. Each joint is cleaned of dust and grit, then primed if required.
  4. A sealant chosen for each area goes in and is tooled smooth.
  5. We check every joint and tell you how long each needs to cure.

Getting ready for the visit

  • Let us know about stairs, lifts or work at height
  • Mention if the joints have been sealed before
  • Mention any sign-in or site rules at work premises

How to look after the new joints

Aftercare is simple:

  • Keep pictures and emails about snagging items
  • Watch for new gaps as the house dries out
  • Do not wait for the house to settle if water is getting through
  • Do not seal over failed sealant yourself

Avoid standing on the rim of the bath or the edge 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. Once it ends, the repair may be down to you, so raise it early.

Why deal with it now?

Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.

Common problems we fix in Allanton

New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open.

If you can see any of these, it’s time to have the joints looked at:

  • Cracked caulk along new skirting
  • Beads laid onto grit and dust from the build
  • Gaps opening as the house dries out and settles
  • Kitchen sealant that has pulled off the wall

Around Allanton, as everywhere, new build mastic is only as good as the preparation behind it.

When something else is needed

Sealant isn’t the answer to every problem, and we will tell you before any work starts. Sealant won’t put right:

  • Leaking fittings rather than failed sealant
  • Cracked trays, tiles or worktops
  • Baths and trays that move too much for sealant to cope with

If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
