Window & door mastic in Cromarty, Highland
Our applicators work in Cromarty on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and a 12-month guarantee.

Signs you need window mastic in Cromarty
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Common reasons people contact us include:
- Old mastic that has gone black or come away
- Rushed sealant from a window installation
- Rain getting in at the frame or under the sill
- Cracked internal joints between frame and plaster
Whether the job is in Cromarty itself or nearby, the right material for each joint matters as much as a neat finish.

Window mastic for homes and businesses in Cromarty
Homes in Cromarty have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you are dealing with gaps between the frame and the inside reveal and rushed sealant from a window installation, we can help.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Each job carries a 12-month guarantee, large or small.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
How the job changes by surface
Patio & French doors
Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Aluminium frames
Coated aluminium needs a compatible sealant. We use a neutral-cure product.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Wash the frames with mild soapy water
- Look round the frames every year or so
- Avoid blasting the frames with a pressure washer
- Air rooms to keep condensation down around windows
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
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.
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a morning for a couple of windows and a door and we leave things clean and tidy. In smaller Scottish places, parking is normally 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.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we are working on
How to get a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll take it from there.

Your questions about window mastic in Cromarty
Does the coastal weather in Cromarty affect outside sealant?
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.

Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.

What affects the cost of window mastic
We quote each job individually. This is what makes a difference:
- Any working-time requirements on site

- How much old sealant there is and how hard it is to remove

Frames and glazing around Cromarty
Cromarty is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. The west of Scotland is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
In and around Cromarty, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
