How we handle window mastic in Lathones
Homes in Lathones have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you are dealing with leaking joints at the ends of sills and cracked or shrunken mastic around the frame, we can put it right, on window sills, timber windows & doors and aluminium frames alike.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

What we do, step by step
We keep the work tidy and contained to the joints we’re treating. The job normally takes a morning for a couple of windows and a door, and we tell you how long to leave it before we go. Outdoor work around Lathones depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints

For landlords and businesses
Letting agents and landlords in Lathones can book us as well as householders. Resealing between tenancies keeps a property looking cared for.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Air rooms to keep condensation down around windows
- Keep timber frames painted
- Clear any debris from frame drain holes
- Do not aim a pressure washer at the joints
Most silicone sealants won’t take paint, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
What window mastic looks like in Lathones
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Historic houses like Gibliston House (about 2.3 miles south-east) are a reminder that the area around Lathones 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 is traditional sand mastic.
If you live in an older home near Largoward Parish Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

Do you need window mastic in Lathones?
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Keep an eye out for these signs:
- Gaps where the sill meets the wall
- Old mastic that has gone black or come away
- Cracked or shrunken mastic around the frame
- White mastic on grey or black frames
Around Lathones, as everywhere, window mastic is only as good as the preparation behind it.

Why it’s worth doing now in Lathones
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Lathones questions
What guarantee comes with window mastic in Lathones?
All our work, in Lathones and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Will you come out to Lathones?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses and we’re fully insured.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Do you have sealant for grey or black windows?
Yes. Grey and black frames get grey or black sealant, and wood-effect frames usually suit brown.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Where are you based?
We work from Crawley. We cover Lathones and the rest of Fife, along with the rest of our area.
What affects the cost of window mastic
We quote each job individually. This is what makes a difference:
- How easy the joints are to reach
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
- Any working-time requirements on site
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Whether it has been sealed before
- Any access issues, like height or stairs
- The address or postcode of the job
- Pictures of the joints, sent by email
Asking for a quote is easy: let us know the job and the location. A few pictures by email make the job easier to understand, and we will take it from there.
