Window mastic in Greenhills

The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you are dealing with draughts coming in around windows and doors and cracked internal joints between frame and plaster, we can help.

Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.

You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

What we are called out for in Greenhills

Sun, frost and rain wear sealant out. Sunlight dries the surface out, until it loses its stretch and starts to crack.

Signs it’s time to call us include:

  • Leaking joints at the ends of sills
  • Rushed sealant from a window installation
  • Old mastic that has gone black or come away
  • Cracked or shrunken mastic around the frame

For landlords with property near Dunlop station, renewing tired window mastic between tenants heads off draught and damp complaints.

Before you book anyone

  • What happens if the job turns out different
  • What the cure time is
  • Who does the work, and how experienced they are
  • Is the old sealant removed completely?

How to choose a mastic man

What we do, step by step

We keep the work tidy and contained to the joints we’re treating. The job normally takes anything from an hour or two to a full day, depending on how many frames there are, and we explain the cure time before we leave. Outdoor work around Greenhills depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.

  1. We start by checking each window and door with you.
  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. We apply a weatherproof sealant to match the frame and tool it neatly.
  5. Every joint is checked before we leave.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Move anything stored near the joints
  • Let us know if you’ve seen damp or leaks

How to look after the new joints

How long the joints last depends on use and care. We suggest:

  • Keep solvents and bleach off the sealant
  • Avoid blasting the frames with a pressure washer
  • Check the mastic once a year
  • Air rooms to keep condensation down around windows

Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just send an email to info@mrmastic.co.uk.

Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.

Window mastic in Greenhills: local notes

Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.

Montgreenan, about 4.4 miles south-west, is one of the historic houses in the wider area around Greenhills, and older homes nearby need a sealant that suits their walls.

Greenhills questions

Is Greenhills within the area you cover?

Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.

Can you help a landlord with a rental near Dunlop station?

Yes. We work for landlords and letting agents as well as homeowners. You can send an email to info@mrmastic.co.uk with the details for a clear quote.

Do you remove the old sealant?

Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

Can you do the inside joint as well?

Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.

Do you work for hotels and businesses?

Yes. Larger jobs can be planned room by room or area by area to suit the site.

What information do you need?

Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.

Can you seal over the old sealant?

No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.

Are you fully insured?

Yes. We are fully insured, and we can confirm the details when we quote.

How the job changes by surface

Composite doors

An exposed front door gets wind-driven rain. We pay most attention there.

uPVC windows

The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.

Your quote is based on your job. We look at:

  • How many rooms, windows or areas are involved

What to tell us for a quote

Photos by email are helpful but not essential. Please mention:

  • Pictures of the joints, sent by email
  • The problem you’ve noticed
  • Roughly how big the job is
  • Where the property is
