Trusted sand mastic in St. Ninians

Sand mastic in St. Ninians

Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted and we’ll advise if you’re redecorating. If you have draughts and rain around sash boxes and cement or filler used on old window joints that has cracked, we can help.

Mastic can only go onto a dry joint, so outside work in St. Ninians depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.

You get a 12-month guarantee, the same in St. Ninians as everywhere else we work.

What the job involves on each surface

Period and listed homes

Materials matter on listed and conservation-area homes. Like-for-like sand mastic is normally favoured.

Timber door frames

Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.

DIY sealant or a professional job?

If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

What happens if it’s left?

New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Why us?

  • Any old sealant cut out fully, not covered over
  • Arbo and Everbuild products
  • We leave the area clean and tidy
  • Every job guaranteed for a year

St. Ninians questions

Do you work for landlords with property near Stirling station?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.

Is St. Ninians within the area you cover?

Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.

Are you insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Can you seal over the old sealant?

No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.

What guarantee comes with the work?

All our work has a one-year guarantee.

What do you put in the joint?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.

Can you quote for more than one area?

Of course. Doing several areas at once is generally more efficient.

Can old silicone round a sash window be swapped for sand mastic?

Yes. We remove the silicone and clean the joint before the sand mastic goes in.

What we’re called out for in St. Ninians

Timber frames move with the seasons. The movement cracks the mastic little by little.

Any of these means the joints need attention:

  • Gaps round a timber door in stone or brick
  • Silicone on a period window that looks wrong
  • Tired mastic found when preparing windows for paint
  • Gaps where the frame meets the masonry

For landlords with property near Stirling station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Our hiring checklist

How the visit works

Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours per window, depending on the condition of the joints. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.

  1. Each surround is checked first.
  2. We rake out the old mastic and clean the joint.
  3. Large voids are packed out.
  4. New sand mastic is applied and shaped by hand.
  5. The finish is dressed neatly.

How to prepare

  • On commercial sites, let us know about site rules
  • Mention if the joints have been sealed before
  • Where the joints are inside, avoid wetting them before we arrive
