Window mastic in Scotstounhill

Common problems we fix in Scotstounhill

Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.

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

  • Untidy mastic left by window fitters
  • Cracked or shrunken mastic around the frame
  • Gaps where the sill meets the wall
  • Draughty joints inside around the window

For an older house near a landmark such as St David's Parish Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

How we handle window mastic in Scotstounhill

Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. If you are dealing with draughts coming in around windows and doors and sealant in the wrong colour for the frame, we can put it right.

In a Scottish city, many flats have windows two, three or four floors up, where failing mastic is easy to miss. Access is the first thing to plan for a job in Scotstounhill.

All our work comes with a one-year guarantee.

Aftercare tips

Aftercare is simple:

  • Ventilate rooms so frames don’t stay wet inside
  • Keep solvents and bleach off the sealant
  • Keep jet washers away from the mastic
  • Make sure the drainage slots are not blocked

Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.

Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.

For landlords and businesses

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.

DIY versus a professional finish

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What window mastic looks like in Scotstounhill

With historic houses such as Tenement House (about 3.6 miles east) nearby, there’s older building stock in the area around Scotstounhill 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. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, and many buildings use a factor to arrange it. Windows usually belong to the flat, but the title deeds have the final say.

If you let a flat or house near Scotstounhill station, renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Jordanhill College are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What happens on the day

There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes most of a day for a typical house, less for a few frames for a typical job. For a tenement in Scotstounhill, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.

  1. First, we go round the frames with you and agree the list.
  2. We remove the old mastic and clean the frame edge and wall.
  3. Deep gaps get closed-cell backing rod to set the depth.
  4. A flexible exterior sealant is applied in a colour to suit the frame.
  5. We tool each bead neatly and check every joint is closed.

Preparing for the visit

  • For business premises, tell us about site rules or sign-in
  • Keep children and pets away from the work area

How we quote for window mastic

Jobs vary more than people expect. The main factors:

  • The product the joint needs
  • How many areas need sealing
  • Mould in or behind the old joints
  • Whether old sealant or filler has to be cut out

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.

What we need to know

To make quoting easier, please include:

  • Where the property is
  • Whether it has been sealed before
  • What the problem is, such as mould, gaps, leaks or cracking
  • Access, such as stairs, a lift or height

For window mastic in Scotstounhill, email us at info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.

Leave it or put it right?

Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Scotstounhill, damp can travel a long way before it shows.

We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
