Window mastic in Longriggend
There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. If you are dealing with whistling draughts around closed windows and gaps left after new windows were fitted, we can put it right, on uPVC windows, composite doors and patio & French doors alike.
Outdoor sealant needs a dry surface, so window work around Longriggend is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Different surfaces, different methods
Composite doors
Draughts round the door leaf normally come from worn seals or adjustment, not the mastic. We will tell you if that is what we find.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
Longriggend: your questions answered
Is Longriggend within the area you cover?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Caldercruix station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Can you get sealant to suit coloured frames?
Yes. Grey and black frames get grey or black sealant, and wood-effect frames generally suit brown.
Landlord and commercial work in Longriggend
Landlords and agents in Longriggend can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
When to call us in Longriggend
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Keep an eye out for any of the following:
- Draughty joints inside around the window
- Old mastic that has gone black or come away
- Water coming in at the bottom corners of a door
- Cracked or shrunken mastic around the frame
Around Longriggend, as everywhere, window mastic is only as good as the preparation behind it.
What to look for in a quote
- Whether VAT is included
- How the surfaces are prepared before sealing
- What product goes in the joint
- Who does the work, and how experienced they are
Longriggend homes and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.

What affects the quote in Longriggend
For a quick quote, just ask. What matters most is:
- Any mould that needs treating
- The type of sealant required
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
Helping us quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- The rough size of the job
- Any access issues, like height or stairs
- Whether it’s a home or a business
- Where the property is
Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we’ll take it from there.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Don’t aim a pressure washer at the joints
- Keep solvents and bleach off the sealant
- Make sure the drainage slots are not blocked
- Wipe condensation off the frames
Most silicone sealants won’t take paint, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
