Window mastic in Prestonpans, done properly
Whether it’s one leaking patio door or every frame on the house, you’ll get a clear quote before any work starts. To get one, drop us a line at info@mrmastic.co.uk with the number of frames and any access details. If you have gaps left after new windows were fitted and a bead that doesn’t match the frame, we can put it right, on window sills, aluminium frames and timber windows & doors alike.
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, so the mastic there works hard.
Each job carries a 12-month guarantee, whatever its size.

What the job involves on each surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones aren’t used, as they can attack some metals. Neutral-cure sealant is the safe choice.
Window sills
Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Frames and glazing around Prestonpans
Prestonpans is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. With historic houses such as Hamilton House (about 0.2 miles south-east) nearby, there’s older building stock in the area around Prestonpans 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.
Rented homes near Prestonpans station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like Preston Lodge High School? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to Prestongrange Parish Church include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

FAQs for Prestonpans
Does living near the coast affect window mastic in Prestonpans?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you cover smaller places like Prestonpans?
Yes, Prestonpans is covered. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you reach windows above the ground floor?
Usually, yes. Access is planned before we start.
How long will my window job take?
It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do you work for letting agents?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.

The process
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for a few frames, or a day or more for a whole house for a typical job. Outdoor work around Prestonpans 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.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Before we arrive
- Mention any tricky access
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit

Landlord and commercial work in Prestonpans
If you manage several properties in or around Prestonpans, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
What happens if it’s left?
Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
