Staffin questions
Is Staffin within the area you cover?

Do you cover Staffin for window mastic?

Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can resealing stop a draught around my window?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.

A handful of frames is a short visit. You’ll get a timescale with the quote.
Window mastic for homes and businesses in Staffin
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. If you have old mastic that has gone black or come away and gaps between the frame and the inside reveal, we can put it right.
In and around a place like Staffin, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
All of our work is guaranteed for twelve months, in Staffin and everywhere else we cover.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

What we’re called out for in Staffin
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. Backing rod sets the right depth.
Most people get in touch after spotting one of these:
- Rushed sealant from a window installation
- Leaking joints at the ends of sills
- Cold air getting in at the frame edge
- Water coming in at the bottom corners of a door
If you look after a building such as Staffin Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- Whether they’re fully insured
- What the cure time is
- Is the old sealant removed completely?
- What preparation is included
What happens if it’s left?
Choosing the product is half the job. Interior caulk and bathroom silicone aren’t made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

What window mastic looks like in Staffin
Staffin is close to 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
In and around Staffin, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
Staffin (Gaelic: Stafainn) is in Highland. Staffin gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. Our Highland coverage runs to 253 places, Staffin among them.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep jet washers away from the mastic
- Air rooms to keep condensation down around windows
- Look round the frames every year or so
- Paint up to the joint, not over it
Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
The process
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a morning for a couple of windows and a door. For a place like Staffin, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts

Related advice
Different surfaces, different methods
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
