Your questions about sand mastic in Glasgow

Can you do sand mastic in Glasgow?

Yes. We work across all of Scotland, and Glasgow is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.

How do repairs to the shared parts of a tenement in Glasgow get organised?

Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not, and we can quote for the factor or the owners directly.

Is there any odour?

Sometimes, a little. It fades as the sealant cures.

Are you ARBOMaster approved?

Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.

Is sand mastic better than silicone for my windows?

It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.

Can you replace silicone on a period window with sand mastic?

Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.

What do you put in the joint?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Do I need permission for sand mastic on a listed building?

It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like, but they decide.

Sand mastic in Glasgow

Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. Typical jobs include draughty sash windows at the surround and failed mastic on an exposed elevation, across tenement windows, sash and case windows and period & listed homes.

Glasgow is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Stone needs a sealant that suits it, so acetoxy silicones, which can attack some stone, are best avoided.

A 12-month guarantee comes as standard.

When it isn’t the sealant

We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:

  • Crumbling stone or brickwork round the window
  • Sashes that rattle, stick or won’t open
  • Planning or listed building consent (your local planning authority decides)

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

How we quote for sand mastic

Your quote is based on your job. We take into account:

  • The type of sealant required
  • Whether there’s mould to deal with
  • Whether old sealant or filler has to be cut out
  • How easy the joints are to reach

Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.

Helping us quote

There’s no need for technical detail. Just tell us:

  • How we’d reach the joints
  • If someone has resealed it before
  • A few photos by email, if you can
  • The address or postcode of the job

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.

Why deal with it now?

Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Wind-driven rain gets into any failed joint on the outside of a city building, and in Glasgow, damp can spread through stone and plaster before anyone sees it.

Combining jobs into one visit normally makes better use of the time than several visits. We will give you a clear price for the lot.

Should I try it myself first?

If you’re 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 does not work out, we can still put it right.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Landlords, agents and businesses in Glasgow

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

We also work for property managers and facilities teams. Several sites can go on one quote.

What the job involves on each surface

Brick reveals

Sand mastic is also used where timber frames meet brick. It gives a traditional finish.

Timber door frames

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

Windows and doors in Glasgow

With historic houses such as Tenement House (about 1 mile north) nearby, there’s older building stock in the area around Glasgow as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.

Letting a property close to Anderston station? Then any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as Our Lady and St Margaret's Primary School, the mastic around its windows and doors needs looking after like any other building’s. Historic houses such as Tenement House, about 1 mile north, show how far back building around Glasgow goes, and older homes nearby need a sealant that suits their walls.

How it 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. All told, the work takes anything from a few hours to a full day, depending on how many windows. Parking in city streets around Glasgow can be tight or controlled, so it helps to know about permits or nearby bays. If you’re in a flat, let us know how we get in at the street door.

  1. First we agree which joints need doing.
  2. We remove the old, loose mastic.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. We apply the mastic by hand and shape it.
  5. The surface is finished to suit the stone or brick.

Getting ready for the visit

  • Mention any leaks or damp you’ve noticed
  • Where the joints are inside, avoid wetting them before we arrive
  • Mention if the joints have been sealed before
