Window Mastic in Longman
Problem with your window and door frames in Longman? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Gaps left after new windows were fitted
- Cold air getting in at the frame edge
- Cracked or shrunken mastic around the frame
Window mastic for homes and businesses in Longman
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We work on window sills, composite doors and uPVC windows, and people most often call us about draughty joints inside around the window and a bead that doesn’t match the frame.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What we’re called out for in Longman
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Any of these means the joints need attention:
- Draughty joints inside around the window
- Gaps where the sill meets the wall
- Sealant in the wrong colour for the frame
- Cold air getting in at the frame edge
Schools such as Millburn Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before booking
- How hidden problems are handled
- How much experience the applicator has

Quotes for window mastic in Longman
We don’t publish a price list, because jobs vary so much. What we look at:
- Whether the work is at height
- Any mould that needs treating
- The number of rooms or windows
- The size of the job
Doing several joints on one visit is generally more efficient than separate visits. We will send you a clear quote for the lot.
Helping us quote
To make quoting easier, let us know:
- Roughly how big the job is
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
- How we’d reach the joints
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we will take it from there.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Common questions in Longman
Do you work for landlords with property near Inverness station?
Yes. We work for letting agents and landlords as well as householders. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Does living near the coast affect window mastic in Longman?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Is the new sealant paintable?
Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Can you get sealant to suit coloured frames?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
What window mastic looks like in Longman
Longman is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. With historic houses such as Old Allangrange House (about 4.2 miles north-west) nearby, there’s older building stock in the area around Longman as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Homes close to East Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Inverness station? Then renewing tired window mastic between tenants heads off draught and damp complaints.
Longman is about 1 mile north of Inverness, in Highland. Jobs in Longman get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. 253 places in Highland are on our list, large and small.

What else we do in Longman
How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of frames, longer for a whole house and we leave things clean and tidy. Around Longman, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- Each frame is looked over and we agree which ones need resealing.
- 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.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
How to get a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
Related advice
Surface by surface
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall.
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.
Why it’s worth doing now in Longman
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Around Longman, water from a failed joint in an older stone home can soak into timber and plaster.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Clean frames with a soft cloth and soapy water
- Look round the frames every year or so
- Keep paint off silicone joints
- Avoid harsh chemicals near the mastic
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just drop us a line at info@mrmastic.co.uk.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
