Window mastic in Brightons, done properly
Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and we give a 12-month guarantee on the work. We are often asked to deal with rushed sealant from a window installation and cracked internal joints between frame and plaster, across patio & French doors, composite doors and aluminium frames.
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.

What affects the cost of window mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- How many rooms, windows or areas are involved
- The size of the job
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
- The rough size of the job
- The address or postcode of the job
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.

Looking after it afterwards
To keep the joints looking good and working properly:
- Avoid blasting the frames with a pressure washer
- Don’t use solvent cleaners on the joint
- Do not paint over the silicone
- Repaint timber before it’s bare
Most silicone sealants won’t take paint, so mention any painting plans before work begins. We can use a paintable sealant where that matters.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
What happens if it’s left?
Resealing frames is a short job: the visit takes a morning for a couple of windows and a door. Wait for damp to appear and there may be plaster and decorating to sort out too. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

When to call us in Brightons
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. Backing rod sets the right depth.
These are the problems we are asked about most:
- Old mastic that has gone black or come away
- Untidy mastic left by window fitters
- Hard, cracked sealant around windows
- Leaking joints at the ends of sills
If you let a flat or house near Polmont station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What happens on the day
At the end, we look at the finished work together. The visit itself generally takes a few hours for a few frames, or a day or more for a whole house, depending on the size of the job. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Clear items away from the joints we’re working on
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can

Advice
Landlords, agents and businesses in Brightons

Windows and doors in Brightons
Brightons 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. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
For site and facilities teams at buildings such as Graeme High School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Brightons Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Questions from Brightons
I let a flat near Polmont station. Can you help?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Does the coastal weather in Brightons affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you cover Brightons?
We do. Brightons is part of the area we cover, and the service is the same as everywhere else.
How do I get a quote for window mastic in Brightons?
It depends on the job, so we quote each one individually. For a quick quote, send an email to info@mrmastic.co.uk and let us know what needs doing and where.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Do you have insurance?
Yes. We are fully insured for domestic and commercial work.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Does the work come with a guarantee?
Yes, with our one-year guarantee. Keeping drainage clear and checking the joints yearly helps them last.
