How we handle external mastic in Hinton Ampner
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what access is needed. We work on joints between brick and frames, concrete & block and brickwork movement joints, and common reasons people get in touch are joints where the bead has come unstuck and plants rooting in failed movement joints.
External sealant needs dry, clean surfaces, so work around Hinton Ampner is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

Landlord and commercial work in Hinton Ampner
Housing providers, facilities teams and property managers book us too in Hinton Ampner and across Hampshire. Several sites can go on one quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
What we’re called out for in Hinton Ampner
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Common reasons people contact us are:
- Plants rooting in failed movement joints
- Gaps where render, brick and frames meet
- Sealant that has lost its bond to the brick or render
- Panel joints letting water in
Managing a site like Cheriton Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Walls and rooflines in Hinton Ampner
Historic houses like Hinton Ampner House (about 0.3 miles south) are a reminder that the area around Hinton Ampner has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant.

When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so these are the limits:
- Damp that is not coming from the joint
- Movement that’s more than a sealant joint can take
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
Joints and surfaces we work on

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What a professional job adds is preparation and the right 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.

Surface by surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
What we do, step by step
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours to a few days, depending on the length of joint and the access in most cases. Somewhere as small as Hinton Ampner, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can

Questions from Hinton Ampner
Will you come out to Hinton Ampner?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What guarantee comes with external mastic in Hinton Ampner?
All our work, in Hinton Ampner and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How long does external mastic take?
As a guide, most jobs take anything from a few hours to several days, depending on the building. Larger jobs naturally take longer, and we’ll say how long yours will take.
Is it OK to fill a movement joint with cement?
No. Rigid materials cannot move with the wall, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Are you insured?
Yes. We are fully insured for domestic and commercial work.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
Why it’s worth doing now in Hinton Ampner
Sealing over the top of old mastic does not hold for long. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. In a small place like Hinton Ampner, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
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.
