Window & door mastic in Whitecraigs, Glasgow
Problem with your window and door frames in Whitecraigs? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Cold air getting in at the frame edge
- Hard, cracked sealant around windows
- Damp patches on the reveal after heavy rain
Window mastic in Whitecraigs
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. If you are dealing with draughty joints inside around the window and hard, cracked sealant around windows, we can help, whatever the surface.
Whitecraigs is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Natural stone around older windows needs a sealant that will not mark or attack it, so acetoxy silicones, which can attack some stone, are best avoided.
Big or small, you get the same one-year guarantee.

What we do, step by step
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours for a handful of frames, longer for a whole house. Inside a flat in Whitecraigs, 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.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit

What else we do in Whitecraigs
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
When something else is needed
In fairness, there are a few things sealant won’t fix:
- Worn gaskets, brush seals or a door that has dropped
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Faulty window hardware
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
What we seal
- Window sills
- Patio & French doors
- Composite doors
- uPVC windows
- Timber windows & doors
- Aluminium frames
Common questions in Whitecraigs
Who arranges sealant work on the shared parts of a tenement in Whitecraigs?
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.
Can you help a landlord with a rental near Whitecraigs station?
Yes, we work for letting agents and landlords. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Is the new sealant paintable?
It depends on the sealant. Silicone isn’t paintable, but some hybrid sealants are. Tell us if you’re decorating and we’ll choose accordingly.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply drop us a line at info@mrmastic.co.uk.
Windows and doors in Whitecraigs
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.
If you let a flat or house near Whitecraigs station, renewing tired window mastic between tenants heads off draught and damp complaints. Historic houses such as Pollok House, about 3 miles north, show how far back building around Whitecraigs goes. Managing a site like Belmont House School? Then the mastic around its windows and doors needs looking after like any other building’s.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Avoid blasting the frames with a pressure washer
- Repaint timber before it’s bare
- Clear any debris from frame drain holes
- Check the mastic once a year
Most silicone sealants won’t take paint, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
Why deal with it now?
Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Private landlords in Whitecraigs must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

How the job changes by surface
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We will tell you if that’s what we find.
