Looking after it afterwards

A little care helps the new joints last. We recommend:

  • Act on the first splits you see
  • Walk round the building once a year and look at the joints
  • Keep movement joints as flexible joints, not mortar
  • Ask before painting over external sealant

Do not paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants are not designed to be painted and spoil the finish.

Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.

External mastic in Chapelton, done properly

Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. Typical jobs include damp patches traced to an open external joint and cracked joints where brick meets render or frames, across brickwork movement joints, concrete & block and render & cladding joints.

External sealant needs dry surfaces, so outdoor work around Chapelton is planned around the weather. Tell us how to reach each wall, gutter and roofline.

Every job is covered by our 12-month guarantee.

What the job involves on each surface

Cladding and façade panels

Where a cladding system has its own specified sealant, we follow it. Send us any details you have about the façade.

Render joints

Water behind render can lead to blown patches. Resealing the joints early keeps water out.

What we can’t put right

Some problems need a builder, plumber or other trade rather than us:

  • Damp that isn’t coming from the joint
  • Movement that is more than a sealant joint can take
  • Failed render or damaged cladding panels

If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.

Where we work in Chapelton

  • Façade panels
  • Concrete & block
  • Render & cladding joints
  • Brickwork movement joints
  • Joints between brick and frames
  • Copings & trims

Signs you need external mastic in Chapelton

Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.

The problems people usually mention when they call include:

  • Cracked joints where brick meets render or frames
  • Water getting into walls through failed joints
  • Joints where the bead has come unstuck
  • Leaking joints around cladding and façade panels

Homes close to Saint Ternan's Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

Questions to ask before you book

  • How the joint is cleaned and prepared
  • What product goes in the joint
  • What the cure time is
  • How the colour is chosen

Our hiring checklist

The process

You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation for a typical job. Outdoor work around Chapelton depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.

  1. First we look over the joints with you, agree which to renew and talk through access.
  2. We cut out the failed sealant and rake out any dirt or growth.
  3. We clean both faces of the joint and prime them where the product calls for it.
  4. We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
  5. We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

Preparing for the visit

  • Let us know about parking restrictions
  • Let us know about earlier repairs to the joints
  • Mention any leaks or damp you’ve noticed

Chapelton buildings and the weather

Chapelton is close to 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 movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.

Letting a property close to Portlethen station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Managing a site like Portlethen Academy? Then its movement joints, gutters and trims need looking after like any other building’s.

Chapelton is about 9 miles south of Aberdeen, in Aberdeenshire. Jobs in Chapelton get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee.

Why act early in Chapelton

Sealing over the top of old mastic does not hold for long. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

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 give you a clear quote for the lot.

Why book with us

  • Arbo and Everbuild products
  • A choice of colours where the product allows
  • You choose the colour before work begins
  • Over 20 years’ experience

Can I do it myself?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Common questions in Chapelton

Does the coastal weather in Chapelton affect outside sealant?

Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.

Do you cover smaller places like Chapelton?

Yes, Chapelton is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Do you use backing rod?

Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.

What do you need from me for a quote?

Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.

Does someone need to be in?

If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.

Where is Mr Mastic based?

Mr Mastic is based in Crawley. We cover Chapelton and the rest of Aberdeenshire, along with the rest of our area.

Do you do commercial work?

Yes. Larger jobs can be planned room by room or area by area to suit the site.

Do you work at height?

That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.
