Window Mastic in Fearnan
Window and door frames in Fearnan need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Rushed sealant from a window installation
- A bead that doesn’t match the frame
- Old mastic that has gone black or come away
Window mastic in Fearnan
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. If you are dealing with rushed sealant from a window installation and cracked internal joints between frame and plaster, we can help, whatever the surface.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Each job carries a 12-month guarantee, whatever its size.

Fearnan: your questions answered
Is there a guarantee on window mastic in Fearnan?
All our work, in Fearnan and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Will you come out to Fearnan?
Yes. Fearnan is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Can you seal the gap between the frame and the plaster indoors?
Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Do you work for letting agents?
Yes. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.

The process
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work starts. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. For a place like Fearnan, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we’re working on
- Mention any leaks or damp you’ve noticed

How the job changes by surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.

Can I do it myself?
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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What window mastic looks like in Fearnan
Fearnan is in the west of Scotland, which is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
In and around Fearnan, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Ventilate rooms so frames don’t stay wet inside
- Use gentle cleaners on frames and sealant
- Avoid blasting the frames with a pressure washer
- Do not use solvent cleaners on the joint
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
Common problems we fix in Fearnan
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Keep an eye out for these signs:
- Black, perished sealant on frames
- Gaps where the sill meets the wall
- Cracked internal joints between frame and plaster
- Cracked or shrunken mastic around the frame
Whether the job is in Fearnan itself or nearby, the right material for each joint matters as much as a neat finish.

What sealant work can’t fix
New sealant cannot fix everything, and we will tell you before work begins. Sealant will not put right:
- Damp problems in the wall away from the window
- Worn gaskets, brush seals or a door that has dropped
- A sash or casement that will not close properly
