External Mastic in Wallyford
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Wallyford and across East Lothian. ARBOMaster approved applicators, fully insured, with a one-year guarantee.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
How we handle external mastic in Wallyford
Low-level joints can usually be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. Common call-outs are for moss and dirt in joints with no sealant left and weathered mastic that no longer stretches, on joints between brick and frames, render & cladding joints and façade panels.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
Whatever the size of the job, you get the same one-year guarantee.

Wallyford: your questions answered
I let a flat near Wallyford station. Can you help?
Yes, we work for landlords and agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
Does living near the coast affect external mastic in Wallyford?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you come to Wallyford?
Yes. We’re based in Crawley and work across South East England, London and Scotland, and that includes Wallyford.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
How long does external mastic take?
Typically it takes a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer, and we will tell you how long to expect.
Can I add another job to the visit?
Yes. Just list everything you need.
When will the joints need doing again?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
Different surfaces, different methods
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two.
Walls and rooflines in Wallyford
Wallyford 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. 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.
If you look after a building such as Loretto School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Wallyford station, outside joints that have cracked can let damp into a rental, so check them between lets.

What we cannot put right
To be straight with you, there are a few things sealant will not fix:
- Cracking across the wall rather than at a joint
- Rising or penetrating damp from elsewhere in the wall
- Structural movement, which needs a surveyor or engineer
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly before you book.

What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours to a few days, depending on the length of joint and the access. Around Wallyford, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises

Advice
For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
What we are called out for in Wallyford
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
If you can see any of these, it’s time to have the joints looked at:
- Sealant pulling away from one side of the joint
- Joints pointed up with cement by mistake
- Movement joints with cracked, split or missing sealant
- Gaps where render, brick and frames meet
Historic houses such as Hamilton House, about 1.9 miles north-east, show how far back building around Wallyford goes, and older homes nearby need a sealant that suits their walls.
What your quote should include
- When the joint can take water or movement
- Whether the sealant suits the joint
- The length of the guarantee
- What happens if they find a problem under the old sealant
What affects the quote in Wallyford
We do not publish a price list, because no two jobs are the same. The quote depends on:
- How many rooms, windows or areas are involved
- How much there is to do
- Mould in or behind the old joints
- The product the joint needs
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.
What we need to know
Before you ask for a quote, have a think about:
- If someone has resealed it before
- The rough size of the job
- A few photos by email, if you can
- Access, such as stairs, a lift or height
Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job, and we’ll take it from there.
