External Mastic in Minstead
External mastic for Minstead and the surrounding area: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Joints pointed up with cement by mistake
- Gaps where render, brick and frames meet
- Joints where the bead has come unstuck
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Clear growth from the base of walls and joints
- Check the sealant is paintable before painting near it
- Never let anyone fill a movement joint with mortar
- Walk round the building once a year and look at the joints
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
External mastic in Minstead
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the line blends in. If you have moss and dirt in joints with no sealant left and movement joints with cracked, split or missing sealant, we can put it right, whatever the surface.
External sealant needs dry, clean surfaces, so work around Minstead is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
Every job comes with our one-year guarantee.

When it is not the sealant
It helps to know what we cannot do too:
- Cracked brickwork or render that needs a builder or plasterer
- Movement that is more than a sealant joint can take
- Render that’s blown, hollow or coming away
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.
Surfaces we seal
- Render & cladding joints
- Copings & trims

Why it’s worth doing now in Minstead
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Where a wall is exposed, as many are in small places like Minstead, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

Outside joints around Minstead
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of All Saints, the joints between older walls, newer extensions and the roofline need a sealant that can move.

How the job changes by surface
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one before the bead.
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Your questions about external mastic in Minstead
Is Minstead in your area for external mastic?
Yes. Our work covers London and the South East, and Minstead is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
Do you work for landlords with property near Ashurst New Forest station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall. There’s a wide choice of exterior colours.
Can you reach joints on upper floors?
It depends on the height and the site. Ground-floor joints are simple; for higher ones, send details and we will confirm the access.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
How do I get a quote for external mastic in Minstead?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before we start.
Common problems we fix in Minstead
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.
Any of these means the joints need attention:
- Sealant pulling away from one side of the joint
- Cracked joints where brick meets render or frames
- Plants rooting in failed movement joints
- Panel joints letting water in
Letting a property close to Ashurst New Forest station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Questions to ask before booking
- Is VAT in the price?
- Whether all the old sealant comes out first
- How hidden problems are handled
- Which colour the sealant will be
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on how much there is to do. In a small place like Minstead, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
- Clear items away from the joints we are working on
