Lonmore Window Mastic
Problem with your window and door frames in Lonmore? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.
- Untidy mastic left by window fitters
- Mastic that is falling out in pieces
- Cracked internal joints between frame and plaster
Window mastic in Lonmore, done properly
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. If you are dealing with gaps between the frame and the inside reveal and a bead that doesn’t match the frame, we can put it right.
Outdoor sealant needs a dry surface, so window work around Lonmore is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Our work is backed for twelve months.

Window mastic in Lonmore: local notes
Lonmore is close to 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. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Whether the job is in Lonmore itself or nearby, the right material for each joint matters as much as a neat finish.

Common questions in Lonmore
Does living near the coast affect window mastic in Lonmore?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Can you do window mastic in Lonmore?
Yes, Lonmore is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
How long will my window job take?
A few frames take a few hours, while a whole house takes longer. You’ll get a timescale with the quote.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep jet washers away from the mastic
- Air rooms to keep condensation down around windows
- Do not use solvent cleaners on the joint
- Repaint timber before it’s bare
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
What we are called out for in Lonmore
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
Signs it’s time to call us include:
- Cracked internal joints between frame and plaster
- Rushed sealant from a window installation
- Cold air getting in at the frame edge
- Leaking joints at the ends of sills
In and around Lonmore, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- Who turns up on the day
- Whether they’re fully insured
- Whether they seal over old material or remove it
- How the colour is chosen
The process
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours for a few frames, or a day or more for a whole house. For a place like Lonmore, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we’re working on
- Try not to wet indoor joints just before the visit

Related advice
Different surfaces, different methods
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
