Do you need window mastic in Clachan?

Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.

Keep an eye out for these signs:

  • Hard, cracked sealant around windows
  • Old mastic that has gone black or come away
  • Draughts coming in around windows and doors
  • Damp patches on the reveal after heavy rain

In and around Clachan, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

How to look after the new joints

Simple care keeps the joints in good condition. Our advice:

  • Paint up to the joint, not over it
  • Do not aim a pressure washer at the joints
  • Do not use solvent cleaners on the joint
  • Look round the frames every year or so

Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.

On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.

Why it’s worth doing now in Clachan

Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. In an older home around Clachan, damp from a failed joint can get into timber and plaster.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

What we cannot put right

Before booking, it’s worth knowing the limits too:

  • Draughts through the window seals rather than the frame
  • Damp coming through the wall itself rather than the frame joint
  • Misting between the panes of a double-glazed unit (that needs a new unit)

Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.

The process

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to a full day, depending on how many frames there are and we leave things clean and tidy. Somewhere like Clachan may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  1. We start by checking each window and door with you.
  2. We remove the old mastic and clean the frame and the wall.
  3. Where gaps are deep, backing rod goes in first.
  4. We apply a weatherproof sealant to match the frame and tool it neatly.
  5. We clear up and check every joint is fully closed.

Before we arrive

  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about stairs, lifts or work at height
  • Tell us about any water getting in

Frames and glazing around Clachan

Clachan 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’s 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.

For jobs in and around Clachan, choosing the right material for each joint is as important as a tidy finish.

Will resealing my frames help with draughts?

Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.

Do I have to be there?

We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.

Do you work on first-floor windows?

Can you work on commercial sites?

What does window mastic cost?

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

Surface by surface

Window sills

Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.

Timber windows & doors

Soft or rotten wood can’t be sealed successfully. If we find rot, we will tell you before going ahead, as that is a job for a joiner.
