What affects the cost of external mastic

Jobs vary more than people expect. What affects the quote:

  • The old material and how stubborn it is
  • The number and length of the joints
  • The type of sealant required
  • How many areas need sealing

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

External mastic for homes and businesses in Dullatur

Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. If you have moss and dirt in joints with no sealant left and old sealant gone brittle and cracked, we can put it right, whatever the surface.

Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard.

Big or small, it’s backed by our one-year guarantee.

What sealant work cannot fix

We will always be straight with you, so here’s what new sealant will not do:

  • Loose or hollow render, which needs re-rendering
  • Adding movement joints to masonry that has none
  • Damp that is not coming from the joint

If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

Where we work in Dullatur

Why it’s worth doing now in Dullatur

The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the damage spreads beyond the joint. In a place like Dullatur, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

The process

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Dullatur 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. Each joint is checked and the colour of the new sealant agreed.
  2. We take out the old sealant until the faces are sound.
  3. Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
  4. Primer is applied wherever the sealant needs it.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Before we arrive

  • On commercial sites, let us know about site rules
  • Tell us if parking is tricky
  • For indoor joints, keep the area dry beforehand if you can

Advice

Should I try it myself first?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Aftercare tips

After the cure time, these simple habits help:

  • Point out the joints to other trades
  • Fix overflowing gutters above sealed joints
  • Keep movement joints as flexible joints, not mortar
  • Leave the joints unpainted unless we have said otherwise

Keep pressure washers away from the sealant. High-pressure water can lift the edges.

If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.

Work for landlords, hotels and businesses

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.

Walls and rooflines in Dullatur

Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Dullatur is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.

Managing a site like Our Lady's High? Then its movement joints, gutters and trims need looking after like any other building’s. Rented homes near Croy station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
