Window & door mastic in Preston, East Lothian
Window mastic for Preston and the surrounding area: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Damp patches on the reveal after heavy rain
- Whistling draughts around closed windows
- Mastic that has split away from the wall
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes most of a day for a typical house, less for a few frames. Outside jobs in Preston 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.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height

Window mastic in Preston
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we’ll tell you. Typical jobs include rain getting in at the frame or under the sill and cold air getting in at the frame edge, across window sills, aluminium frames and timber windows & doors.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
Each job carries a 12-month guarantee, whatever its size.

What affects the cost of window mastic
Jobs vary more than people expect. What affects the quote:
- Whether old sealant or filler has to be cut out
- The product the joint needs
- The number of rooms or windows
- The size of the job
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.
Helping us quote
To help us quote quickly, let us know:
- Roughly how big the job is
- If someone has resealed it before
- A few pictures by email, if you can
- Whether it’s a home or a business
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved.
Why it’s worth doing now in Preston
The work is quick compared with the damage it prevents: the visit takes a few hours for a few frames, or a day or more for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. In an older home around Preston, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
What we are called out for in Preston
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.
Common reasons people contact us include:
- Gaps where the sill meets the wall
- Mastic that has split away from the wall
- Gaps left after new windows were fitted
- Sealant in the wrong colour for the frame
For landlords with property near East Linton station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
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. All the old material has to come out first.
What window mastic looks like in Preston
Preston is within about 3 miles of 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. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
If you live in an older home near Prestonkirk Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Questions from Preston
Do you cover smaller places like Preston?
Yes, Preston is covered. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Does living near the coast affect window mastic in Preston?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first.
How many windows can you do in a day?
A few frames take a few hours. You’ll get a timescale with the quote.
What does window mastic cost?
Every job is different, so each one gets its own quote. To get one, email us at info@mrmastic.co.uk with a short description of the job.
Do you have sealant for grey or black windows?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Honest limits
We’ll always be straight with you, so here’s what sealant cannot fix:
