Window mastic for homes and businesses in Carberry
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on patio & French doors, composite doors and uPVC windows, and people most often call us about untidy mastic left by window fitters and white mastic on grey or black frames.
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.
Every job comes with our 12-month guarantee, wherever you are in East Lothian.

Surface by surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so they get particular care.
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
For landlords and businesses
We also work for property managers and facilities teams in Carberry and across East Lothian. We can quote a run of properties together.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
The process
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a few frames, or a day or more for a whole house. Outside jobs in Carberry need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
How to prepare
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area
- Mention if the joints have been sealed before

Windows and doors in Carberry
Carberry 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, often pointed into the wall with traditional sand mastic.
Hamilton House, about 3.2 miles north-east, is one of the historic houses in the wider area around Carberry, and older homes nearby need a sealant that suits their walls. If you let a flat or house near Wallyford station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Carberry is about 2 miles south-east of Musselburgh, in East Lothian. From the centre of Carberry to the outskirts, we cover window mastic for every kind of property, from flats and houses to offices and hotels.

Carberry questions
Will you come out to Carberry?
Yes, Carberry is covered. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is window mastic in a coastal place like Carberry any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we are using and why.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels in Carberry.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Will new mastic stop draughts?
It will if the frame joint is the problem. We check where the draught is before work begins.
Looking after it afterwards
So the new joints stay in good condition:
- Keep paint off silicone joints
- Clean frames with a soft cloth and soapy water
- Make sure the drainage slots aren’t blocked
- Keep timber frames painted
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just drop us a line at info@mrmastic.co.uk.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
What we are called out for in Carberry
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
Most people get in touch when they notice one of these:
- Rain getting in at the frame or under the sill
- Black, perished sealant on frames
- Gaps where the sill meets the wall
- Untidy mastic left by window fitters
For site and facilities teams at buildings such as Loretto School, larger buildings have plenty of frames, and the mastic around each one ages.
