External mastic in Haddington, done properly
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. If you are dealing with water getting into walls through failed joints and joints pointed up with cement by mistake, we can put it right.
Scottish towns like Haddington mix older stone buildings with newer estates of brick, render and uPVC trims. Each has its own weak points: worn joints in old gutters, and dried-out movement joints in newer walls.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Walls and rooflines in Haddington
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
In the older streets around West Parish Kirk and Tower, an extension built onto an older house moves differently, and the joint between them takes the strain. If you let a flat or house near Drem station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as Knox Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
How long before the joint can be used?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
The process
At the end, we look at the finished work together. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the amount of work.

- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.

Advice
Why act early in Haddington
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together. In Haddington, wind and rain soon get through failed outside joints. Indoors, failed sealant lets water into floors and ceilings.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
Why us?
- Colour agreed with you before work begins
- Any old sealant cut out fully, not covered over
- Anti-fungal sanitary silicone in wet areas
- Over 20 years’ experience

What the job involves on each surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
What else we do in Haddington
DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
What affects the cost of external mastic
Jobs vary more than people expect. What affects the quote:
- How much there is to do
- How many rooms, windows or areas are involved
- Whether the work is at height
- Whether old sealant or filler has to be cut out
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
What to tell us for a quote
To make quoting easier, let us know:
- Access, such as stairs, a lift or height
- The rough size of the job
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we will explain what’s involved.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Check the sealant is paintable before painting near it
- Show decorators and builders where the movement joints are
- Avoid pressure-washing directly into sealant joints
- Clear growth from the base of walls and joints
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
