About our sand mastic in Kentallen

For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We work on period & listed homes, tenement windows and sash and case windows, and common reasons people get in touch are window mastic to renew ahead of painting and mastic dropping out of the joint.

Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.

All our work is covered by our one-year guarantee.

Leave it or put it right?

A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

Quotes for sand mastic in Kentallen

There’s no set price list, because no two jobs are the same. The quote depends on:

  • Access and height
  • Any mould that needs treating
  • Any working-time requirements on site
  • How much old sealant there is and how hard it is to remove

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

What we need to know

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • The problem you’ve noticed
  • How we’d reach the joints
  • If it’s domestic, commercial or a hotel
  • Roughly how big the job is

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.

DIY versus a professional finish

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.

If you are 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.

Do you need sand mastic in Kentallen?

Timber frames move with the seasons. The movement cracks the mastic little by little.

The problems people normally mention when they call include:

  • Gaps where the frame meets the masonry
  • Window mastic to renew ahead of painting
  • Mastic round period door frames that has failed
  • Mastic dropping out of the joint

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

Before booking anyone

  • Is VAT in the price?
  • Which colour the sealant will be
  • Who does the work, and how experienced they are
  • How the joint is cleaned and prepared

How to choose a mastic man

What happens on the day

Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a single window, longer for several. Somewhere like Kentallen 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 look at the surrounds with you and agree the joints to renew.
  2. Old mastic and any loose material are raked out.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. We dress the finish so it sits neatly against the masonry.

Getting ready for the visit

  • Let us know if you’ve seen damp or leaks
  • For indoor joints, keep the area dry beforehand if you can
  • Mention any sign-in or site rules at work premises

What sand mastic looks like in Kentallen

Kentallen 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. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.

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

How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Check the mastic when you check the paintwork
  • Have rotten timber repaired before new mastic goes in
  • Ask us before painting near the mastic
  • Clear gutters so water does not pour onto the windows

Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.

Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.

Can you work on commercial sites?

Yes. Larger jobs can be planned room by room or area by area.

Can I add another job to the visit?

Will the old sealant be removed?

Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
