Window mastic in Pumpherston: 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.
For an older house near a landmark such as St Andrew's Church, the joint between an old wall and a newer frame is normally the first place rain gets in. For site and facilities teams at buildings such as Inveralmond Community High School, the mastic around its windows and doors needs looking after like any other building’s.

Window mastic for homes and businesses in Pumpherston
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 gaps left after new windows were fitted, on patio & French doors, timber windows & doors and aluminium frames.
In and around a place like Pumpherston, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
Our work is backed for twelve months.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Paint up to the joint, not over it
- Look round the frames every year or so
- Clean frames with a soft cloth and soapy water
- Keep drainage slots and sill grooves clear
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.

The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a morning for a couple of windows and a door and we leave things clean and tidy. Outdoor work around Pumpherston depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks

Advice
What the job involves on each surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Window sills
Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.
Leave it or put it right?
Resealing frames is a short job: it takes a few hours for a handful of frames, longer for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. In a place like Pumpherston, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
The cost reflects the work involved, not guesswork. That is why we ask about the job first.
Why us?
- More than 20 years in sealant work
- Quality sealants from Arbo and Everbuild
- Sanitary silicone with an anti-fungal additive in wet areas
- Tidy, careful work

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Draughts through the window seals rather than the frame
- Soft or decayed wood in the frame
- Broken hinges, locks or handles
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before booking.
Surfaces we seal
- Timber windows & doors
- uPVC windows
- Window sills
- Aluminium frames
- Patio & French doors
- Composite doors
What we’re called out for in Pumpherston
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. That’s what backing rod is for.
Any of these means the joints need attention:
- Gaps between the frame and the inside reveal
- Draughts coming in around windows and doors
- Gaps where the sill meets the wall
- Old mastic that has gone black or come away
If you let a flat or house near Uphall station, renewing tired window mastic between tenants heads off draught and damp complaints.
