Window mastic for homes and businesses in Ravenscraig
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have mastic that’s falling out in pieces and cracked internal joints between frame and plaster, we can put it right, on window sills, uPVC windows and composite doors alike.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Your job is guaranteed for a year, as with all our work.

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 call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Ravenscraig questions
Will you come out to Ravenscraig?

Is Ravenscraig in your area for window mastic?
Yes. Our work covers the whole of Scotland, and Ravenscraig is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Can I paint over the new sealant?
Not generally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.

Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
Does someone need to be in?

Other services in Ravenscraig
What we’re called out for in Ravenscraig
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
Signs it’s time to call us include:
- Mastic that has split away from the wall
- Mastic that is falling out in pieces
- Draughts coming in around windows and doors
- Water coming in at the bottom corners of a door
Historic houses such as Cambusnethan House, about 2.7 miles south, show how far back building around Ravenscraig goes, and older homes nearby need a sealant that suits their walls.
What to look for in a quote
- Whether they seal over old material or remove it
- How the surfaces are prepared before sealing
- Who does the work, and how experienced they are
- How the colour is chosen
When something else is needed
New sealant can’t fix everything, and we’ll tell you before we start. Sealant will not put right:
- Broken hinges, locks or handles
- Damp problems in the wall away from the window
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before you book.
Joints and surfaces we work on
- uPVC windows
- Aluminium frames
- Composite doors
- Patio & French doors
- Window sills
- Timber windows & doors
Surface by surface
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We’ll tell you if that’s what we find.
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain cannot run into the wall.
What window mastic looks like in Ravenscraig
With historic houses such as Cambusnethan House (about 2.7 miles south) nearby, there’s older building stock in the area around Ravenscraig as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
For site and facilities teams at buildings such as Our Lady's High School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Shieldmuir station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Leave it or put it right?
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
How it works
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes anything from an hour or two to a full day, depending on how many frames there are in most cases. Outside jobs in Ravenscraig need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks
