External mastic for Drummore homes and businesses

Do you need external mastic in Drummore?

The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.

Look out for these signs:

  • Rigid filler in a joint that should flex
  • Brick movement joints where the sealant has split
  • Sealant that has lost its bond to the brick or render
  • Moss and dirt in joints with no sealant left

Around Drummore, as everywhere, external mastic is only as good as the preparation behind it.

What your quote should include

  • What guarantee comes with the work
  • Who does the work, and how experienced they are
  • Whether they’re fully insured
  • How the surfaces are prepared before sealing

How to choose a mastic man

External mastic in Drummore

Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. We’re often asked to deal with sealant pulling away from one side of the joint and joints pointed up with cement by mistake, on façade panels, copings & trims and concrete & block.

In and around a place like Drummore, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.

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

Drummore questions

Does the coastal weather in Drummore affect outside sealant?

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Is Drummore in your area for external mastic?

Yes. Our work covers the whole of Scotland, and Drummore is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear price.

Is there a guarantee?

Yes, always. There’s a 12-month guarantee on every job.

Do you take out the old sealant first?

Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Is it OK to fill a movement joint with cement?

No, not if it’s a movement joint. Pointing it stops it working, and the wall may crack nearby. A flexible sealant is the right fill.

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.

Can I add another job to the visit?

Yes, we can. Several rooms, windows or areas can go on one quote.

How often do external joints need resealing?

That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

A DIY attempt does not rule out a professional job. We cut it out and start again.

Honest limits

A few problems are outside what sealant work can do:

  • Render that’s blown, hollow or coming away
  • Structural movement, which needs a surveyor or engineer
  • Damp that is not coming from the joint

If in doubt, email us at info@mrmastic.co.uk and we will say what we think.

Why act early in Drummore

An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost near the open joint, so the problem grows beyond the joint itself. In a place like Drummore, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.

Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

  • We never seal over old sealant

External mastic in Drummore: local notes

Drummore 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 is hard on movement joints and outside wall joints, especially on the side facing the sea. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.

In the older streets around Old Parish Church and Burial-Ground, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Drummore is about 16 miles south of Stranraer, in Dumfries and Galloway. Every kind of property in Drummore can book us for external mastic, old or new, large or small. The work is guaranteed for a year. Across Dumfries and Galloway, we cover 138 places, and Drummore is one of them.

What we do, step by step

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to several days, depending on the building from start to finish. For a place like Drummore, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  1. We start by walking round the building and agreeing the joints and the access.
  2. Every bit of old sealant and any mortar or debris is cut out.
  3. Joint faces are cleaned back and primed if the sealant needs it.
  4. Backing rod sized to the joint goes in to set the depth.
  5. We apply the sealant, tool it and check the whole run.

How to prepare

  • Move anything stored near the joints
  • Try not to wet indoor joints just before the visit
  • On commercial sites, let us know about site rules
