External & façade joints in Rumford, Falkirk
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Rumford and across Falkirk. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.

How it works
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. Outside jobs in Rumford need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children

About our external mastic in Rumford
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. If you have cracked joints where brick meets render or frames and failed sealant between panels on a façade, we can help.
External sealant needs dry surfaces, so outdoor work around Rumford is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.

What happens if it’s left?
Running new sealant over the old bead rarely lasts. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Around Rumford, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and send you a clear quote before work begins.

What we cannot put right
In fairness, there are a few things sealant won’t fix:
- Movement that is more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracks in the bricks or render themselves, away from the joints
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before you book.

Common questions in Rumford
I let a flat near Polmont station. Can you help?
Yes, landlords and agents are among the people we work for. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Is external mastic in a coastal place like Rumford any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses.
When is the sealant fully cured?
It depends on the product. Before we leave, we’ll tell you the cure time.
Can a movement joint be filled with mortar?
No. Cement or mortar cannot stretch. Where a joint has been mortared, it can often be raked out and sealed properly.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly and renew it when it starts to fail.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Different surfaces, different methods
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly where it can be done safely.
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.

Walls and rooflines in Rumford
Rumford is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
If you let a flat or house near Polmont station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Do you need external mastic in Rumford?
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
Common reasons people contact us include:
- Gaps where render, brick and frames meet
- Movement joints filled with mortar instead of sealant
- Movement joints with cracked, split or missing sealant
- Weathered mastic that no longer stretches
In the older streets around Brightons Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Walk round the building once a year and look at the joints
- Ask before painting over external sealant
- Deal with leaking gutters that soak the joints below
- Don’t let climbing plants root in the sealant
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.
Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
