DIY sealant or a professional job?

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

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.

Different surfaces, different methods

Timber door frames

Sand mastic is used round timber door frames too. The method is the same as for windows.

Period and listed homes

Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.

How we quote for sand mastic

You’ll get a clear quote before we start. It’s based on:

  • The type of sealant required
  • The number and length of the joints
  • Mould in or behind the old joints
  • Whether the work is at height

The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.

Helping us quote

You do not need to know the technical terms. It helps if you can tell us:

  • Where the job is, and your postcode
  • If someone has resealed it before
  • The problem you’ve noticed
  • How many joints, rooms or windows are involved

There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To arrange one, send an email to info@mrmastic.co.uk.

What sand mastic looks like in Duddingston

Duddingston is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.

If you look after a building such as Holy Rood High School, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around Duddingston Kirk, the joint between an old wall and a newer frame is generally the first place rain gets in.

Questions from Duddingston

Do you cover smaller places like Duddingston?

Yes. Duddingston is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.

How long does the job take?

That depends on the amount of work, but as a guide it takes a few hours for a single window, longer for several. We will tell you when we quote.

Do the sealants smell?

That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

Which products do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

What does sand mastic cost?

It depends on the job, so we quote each one individually. To get one, send an email to info@mrmastic.co.uk and tell us what needs doing and where.

Should I check with the council before work on a listed or conservation-area home?

Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish, but they decide.

Do I have to be there?

It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.

How the visit works

You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a single window, longer for several in most cases. Somewhere like Duddingston may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.

  1. First, we look at the surrounds with you and agree what needs doing.
  2. The loose and crumbling mastic is raked out and the joint cleaned.
  3. Large voids are packed out first, so the mastic isn’t too thick.
  4. Sand mastic is mixed and applied by hand, then shaped to the joint.
  5. The finish is dressed so it sits neatly against the stone or brick.

Preparing for the visit

  • Clear items away from the joints we’re working on
  • Let us know about earlier repairs to the joints
  • On commercial sites, let us know about site rules
