Window mastic for Woodside homes and businesses

When it is not the sealant

In fairness, there are a few things sealant won’t fix:

  • Soft or decayed wood in the frame
  • Misting between the panes of a double-glazed unit (that needs a new unit)
  • Penetrating damp from a failed cavity tray or render

If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

About our window mastic in Woodside

A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. Common call-outs are for mastic that’s falling out in pieces and cracked or shrunken mastic around the frame, on composite doors, timber windows & doors and window sills.

Tenement flats in Scotland’s cities often have windows high above the street, where failing mastic is easy to miss. Access is the first thing to plan for a job in Woodside, and in a tenement the outside of the building may be a shared repair.

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Window mastic in Woodside: local notes

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. The west of Scotland is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.

For an older house near a landmark such as St Vincent Street Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as College of Piping, its window and door frames need their mastic kept sound, just like a home’s.

When to call us in Woodside

Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. A sealant that can’t keep up eventually tears.

The problems people usually mention when they call include:

  • Mastic that is falling out in pieces
  • Sealant in the wrong colour for the frame
  • Gaps where the sill meets the wall
  • Damp patches on the reveal after heavy rain

Letting a property close to Charing Cross (Glasgow) station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

What your quote should include

  • What preparation is included
  • Who does the work, and how experienced they are
  • Whether all the old sealant comes out first
  • How the colour is chosen

10 questions to ask before booking

Different surfaces, different methods

Window sills

Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.

Composite doors

Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We will tell you if that’s what we find.

FAQs for Woodside

Do you cover Woodside for window mastic?

Yes. Our work covers the whole of Scotland, and Woodside is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.

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

The owners of the flats normally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds do not. Your title deeds will say who owns the windows.

Is there any odour?

That depends on the sealant. Some products have a noticeable smell, others very little.

Can tenants book the work?

Of course. Ask your landlord first, and we can send them the quote if that helps.

Do you seal inside as well as outside?

Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.

Do you have insurance?

Yes, we are fully insured.

Can you seal over the old sealant?

No, because it fails. The old sealant always comes out first.

Do you do commercial work?

Yes. Hotels, offices and other businesses use us.

Why deal with it now?

Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. Scottish rain finds any gap around a frame or wall joint, and in Woodside, damp can spread through stone and plaster before anyone sees it.

A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.

DIY versus a professional finish

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

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What we do, step by step

Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes most of a day for a typical house, less for a few frames and we leave things clean and tidy. Inside a flat in Woodside, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.

  1. We check each frame and agree which ones need doing.
  2. Next the failed sealant is cut away and the joint cleaned.
  3. We fit backing rod in deep gaps so the sealant is the right depth.
  4. New exterior sealant goes on in a matching colour and is tooled smooth.
  5. We clear up and check every joint is fully closed.

Preparing for the visit

  • Let us know about parking restrictions
  • Keep pets and children clear of the area while we work
  • Tell us about any previous sealing or DIY attempts
