Why deal with it now?

Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Wind-driven rain gets into any failed joint on the outside of a city building, and in Jordanhill, damp can spread through stone and plaster before anyone sees it.

Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

How we handle sand mastic in Jordanhill

Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it and we’ll advise if you’re redecorating. We work on brick reveals, tenement windows and timber door frames, and the jobs we see most are mastic round period door frames that has failed and tired mastic found when preparing windows for paint.

Sash and case windows are a feature of older tenements in all four Scottish cities, and plenty still have them. Whether you are in a tenement flat or a house in Jordanhill, the joint between frame and wall is what keeps the weather out.

A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Landlord and commercial work in Jordanhill

Letting agents often deal with us directly. Tell us the address, the job and how access works.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.

Aftercare tips

Simple care keeps the joints in good condition. Our advice:

  • Renew mastic before redecorating the windows
  • Check the mastic when you check the paintwork
  • Go gently near the mastic when preparing windows
  • Do not paint over the new mastic

Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.

Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.

What we are called out for in Jordanhill

Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows.

Look out for these signs:

  • Cement or filler used on old window joints that has cracked
  • Window mastic to renew ahead of painting
  • Modern sealant on a period surround
  • Weathered mastic on the most exposed windows

Homes close to Jordanhill Parish Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

Choosing a sealant specialist

What we do, step by step

Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours per window, depending on the condition of the joints. In a city area like Jordanhill, parking may be by permit or pay-and-display, so tell us what’s nearby. 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. Old mastic and any loose material are raked out.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. We dress the finish so it sits neatly against the masonry.

Before we arrive

  • Move anything stored near the joints
  • Let us know about parking restrictions
  • Let us know about stairs, lifts or work at height

Common questions in Jordanhill

Who arranges sealant work on the shared parts of a tenement in Jordanhill?

Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not.

Do you work for landlords with property near Scotstounhill station?

Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.

Typically it takes a few hours for a single window, longer for several. Bigger jobs take longer, and we’ll tell you how long to expect.

It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.

Can I do it myself?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

Is it OK to seal over old sealant?

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

Do you guarantee sand mastic work?

There’s a 12-month guarantee on every job, sand mastic included.

Sand mastic in Jordanhill: local notes

Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, and many buildings use a factor to arrange it. Windows usually belong to the flat, but the title deeds have the final say. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.

For site and facilities teams at buildings such as Jordanhill College, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Scotstounhill station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
