Common questions in Newmills
Does living near the coast affect external mastic in Newmills?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Is Newmills within the area you cover?
Yes. Newmills is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Why do you put foam in the joint first?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
What do you need from me for a quote?
Let us know what needs doing and where, plus photos if you have them. We will ask anything else we need to know.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint can’t move, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Newmills, along with the rest of our area.
External mastic for homes and businesses in Newmills
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. Typical jobs include plants rooting in failed movement joints and gaps where render, brick and frames meet, across joints between brick and frames, brickwork movement joints and render & cladding joints.
In and around a place like Newmills, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
Every job is covered by our 12-month guarantee, wherever you are in Fife.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the building and we leave things clean and tidy. Somewhere like Newmills may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work

What affects the quote in Newmills
Some jobs are bigger than they look, and some smaller. The main factors:
- The type of sealant required
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What to tell us for a quote
What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- The address or postcode of the job
- The type of property
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
When to call us in Newmills
Some movement joints have been pointed up with mortar by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
If you can see any of these, it’s time to have the joints looked at:
- Gaps where render, brick and frames meet
- Brick movement joints where the sealant has split
- Hard, crazed mastic that has stopped moving
- Joints where the bead has come unstuck
If you look after a building such as Craigflower Preparatory School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Newmills buildings and the weather
Newmills 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Homes close to Torryburn Parish Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

What the job involves on each surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Send us any details you have about the façade.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.

When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Cracking across the wall rather than at a joint
- Failed render or damaged cladding panels
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before booking.
What we seal
- Façade panels
- Joints between brick and frames
- Concrete & block
- Copings & trims
- Render & cladding joints
- Brickwork movement joints
Why act early in Newmills
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
