Kinrossie: your questions answered
Is Kinrossie within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you cover Kinrossie for external mastic?
Yes, Kinrossie is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before we start.
Where do you work from?
Our base is Crawley. We work across South East England, London and Scotland.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
What is backing rod for?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
External mastic for homes and businesses in Kinrossie
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. We work on concrete & block, brickwork movement joints and joints between brick and frames, and people most often call us about plants rooting in failed movement joints and gaps where render, brick and frames meet.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
All of our work is guaranteed for twelve months.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Outside joints around Kinrossie
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Whether the job is in Kinrossie itself or nearby, the right material for each joint matters as much as a neat finish.

The process
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours to a few days, depending on the length of joint and the access. Around Kinrossie, 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.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children

Advice
Surface by surface
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. We choose the product to suit.
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best year round.
Aftercare tips
Aftercare is simple:
- Get split or bare joints resealed while the damage is small
- Keep high-pressure jets off the joints
- Do not let climbing plants root in the sealant
- Never let anyone fill a movement joint with mortar
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
A joint that has stopped moving pushes the movement elsewhere, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
Do you need external mastic in Kinrossie?
If plants are growing out of a joint, the sealant has generally failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
These are the problems we are asked about most:
- Panel joints letting water in
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
- Movement joints with cracked, split or missing sealant
In and around Kinrossie, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

What else we do in Kinrossie
How we quote for external mastic
We don’t publish a price list, because no two jobs are the same. What we look at:
- Which sealant suits the joint
- The old material and how stubborn it is
- Access and height
- The number of rooms or windows
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What to tell us for a quote
When you contact us, these details help:
- Pictures of the joints, sent by email
- Whether it has been sealed before
- How many joints, rooms or windows are involved
- The type of property
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we will talk you through the work.
Honest limits
New sealant can’t fix everything, and we’ll tell you before we start. It will not solve:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Subsidence or other structural problems
- Loose or hollow render, which needs re-rendering
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.
