Sand mastic for sash & case windows in Lendalfoot, South Ayrshire
Problem with your window and door surrounds in Lendalfoot? We remove the old material, prepare the joints and seal them properly.
- Crumbling sand mastic round a window
- Silicone on a period window that looks wrong
- Draughty sash windows at the surround
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Get any rot dealt with first
- Look over the window mastic once a year
- Clear gutters so water does not pour onto the windows
- Sort the mastic before the decorators arrive
Do not run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
How we handle sand mastic in Lendalfoot
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We work on stone surrounds, timber door frames and period & listed homes, and people most often call us about mastic that needs renewing before redecorating and open joints round the window box.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
A one-year guarantee comes as standard.

Surface by surface
Stone surrounds
We take care not to mark the stone while raking out the old mastic.
Tenement and terrace windows
Upper-floor windows need access planning. Tell us the height and we will confirm what’s needed.
Lendalfoot homes and the weather
Lendalfoot 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’s hard on the mastic around older windows and doors, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Around Lendalfoot, as everywhere, sand mastic is only as good as the preparation behind it.

How it works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours per window, depending on the condition of the joints. Outside jobs in Lendalfoot need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Let us know about parking restrictions
- On commercial sites, let us know about site rules
- Clear the area around the work

Common questions in Lendalfoot
Do you cover Lendalfoot for sand mastic?
Yes. Our work covers the whole of Scotland, and Lendalfoot is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Is Lendalfoot within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
Can old silicone round a sash window be swapped for sand mastic?
Generally, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply send an email to info@mrmastic.co.uk.
What is sand mastic?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and shaped to suit the surround.
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

When to call us in Lendalfoot
Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
Any of these means the joints need attention:
- Wind and rain getting in round a sash window
- Cracked mastic round a front door frame
- Open joints round the window box
- Old sand mastic that has cracked, crumbled or fallen out
For jobs in and around Lendalfoot, choosing the right material for each joint is as important as a tidy finish.
