Frames and glazing around Blochairn
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Historic houses like Provand's Lordship (about 0.9 miles south-west) are a reminder that the area around Blochairn has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For an older house near a landmark such as Our Lady of Good Counsel Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Alexandra Parade station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Window mastic in Blochairn
Homes in Blochairn have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you’re dealing with gaps where the sill meets the wall and cracked internal joints between frame and plaster, we can help.
Blochairn 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, which normally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
The work is covered for a year after we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

FAQs for Blochairn
Can you do window mastic in Blochairn?
Yes. We work across all of Scotland, and Blochairn is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Do you work for landlords with property near Alexandra Parade station?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What the job involves on each surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
How it works
We bring everything the job needs with us. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a morning for a couple of windows and a door. Parking in city streets around Blochairn can be tight or controlled, so it helps to know about permits or nearby bays. If you’re in a flat, let us know how we get in at the street door.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Before we arrive
- Keep children and pets away from the work area
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Paint up to the joint, not over it
- Avoid harsh chemicals near the mastic
- Avoid blasting the frames with a pressure washer
- Walk round the house once a year and look at the joints
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
What sealant work can’t fix
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Draughts through the window seals rather than the frame
- Damp coming through the wall itself rather than the frame joint
- Misting between the panes of a double-glazed unit (that needs a new unit)
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before booking.

What affects the quote in Blochairn
We quote each job individually. These are the things that affect it:
- Any working-time requirements on site
- Any mould that needs treating
- Which sealant suits the joint
- How many areas need sealing
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
When you call or email, it’s useful to know:
- A few photos by email, if you can
- What’s wrong with the joints now
- Whether it has been sealed before
- Any access issues, like height or stairs
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.

What else we do in Blochairn
What we’re called out for in Blochairn
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
It’s worth asking for a quote if you see:
- Sealant in the wrong colour for the frame
- Rain getting in at the frame or under the sill
- Mastic that is falling out in pieces
- Draughts coming in around windows and doors
Managing a site like St. Roch's Secondary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
What to look for in a quote
- Is the old sealant removed completely?
- How long the guarantee is
- How much experience the applicator has
- How long to leave it before use
