Window Mastic in Fraserburgh
Mastic around window and door frames, sills and patio doors for homeowners, landlords and businesses in Fraserburgh. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Cracked sealant at the sill ends
- Mastic that has split away from the wall
- Rain getting in at the frame or under the sill
About our window mastic in Fraserburgh
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. We work on aluminium frames, window sills and uPVC windows, and common reasons people get in touch are cracked sealant at the sill ends and cracked or shrunken mastic around the frame.
In a town like Fraserburgh, stone-built older streets generally sit alongside harled houses and newer estates, and windows range from older sash and case to modern uPVC. The sealant has to suit both the frame and the wall it sits in.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

How to look after the new joints
To keep the joints looking good and working properly:
- Use gentle cleaners on frames and sealant
- Wipe condensation off the frames
- Keep jet washers away from the mastic
- Repaint timber before it’s bare
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
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.
Work for landlords, hotels and businesses
If you manage several properties in or around Fraserburgh, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and pictures by email help.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Why deal with it now?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. For landlords in Fraserburgh, damp and leaks can fall under the Repairing Standard. Sorting failed joints early is easier than dealing with a tenant’s complaint.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.
What you get with us
- An ARBOMaster approved applicator
- We never seal over old sealant

What affects the quote in Fraserburgh
The quote reflects the job in front of us. We look at:
- The amount of work
- How many areas need sealing
- Whether old sealant or filler has to be cut out
- Access and height
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- If someone has resealed it before
- Any access issues, like height or stairs
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job, and we’ll take it from there.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
When it is not the sealant
Before booking, it’s worth knowing the limits too:
- Soft or decayed wood in the frame
- Condensation trapped between the panes
- A door that needs adjusting, rehanging or new seals
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.

Frames and glazing around Fraserburgh
Fraserburgh is within about 1 mile of 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Schools such as Fraserburgh Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Around Fraserburgh, as everywhere, window mastic is only as good as the preparation behind it.
Fraserburgh is about 37 miles north of Aberdeen, in Aberdeenshire. Across the AB43 area, we cover window mastic for homes and businesses. Across Aberdeenshire, we cover 161 places, Fraserburgh among them. Our Aberdeen page covers work nearby, about 37 miles away.

How the visit works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for a handful of frames, longer for a whole house. In a Scottish town like Fraserburgh, parking is normally straightforward, though older centres can be tighter. For flats, mention the shared stair or door entry system.
- 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.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- Move anything stored near the joints

Your questions about window mastic in Fraserburgh
Is window mastic in Fraserburgh guaranteed?
All our work, in Fraserburgh and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Does living near the coast affect window mastic in Fraserburgh?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
Do you work in Fraserburgh?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, Fraserburgh included.
Can you do the inside joint as well?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
