External mastic for homes and businesses in Red Rice
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on joints between brick and frames, render & cladding joints and façade panels, and the jobs we see most are leaking joints around cladding and façade panels and cracked joints where brick meets render or frames.
In a village or hamlet like Red Rice, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

Surface by surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
What happens on the day
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Red Rice, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules

External mastic in Red Rice: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Redrice School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as Church of St Mary the Virgin, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What’s near Red Rice
Typical jobs here are in homes near Abbotts Ann Church of England Primary School and John Hanson Community School, among other places. The closest station to Red Rice is Andover station, about 2.6 miles north-east. A little further out are Andover Museum (2.8 miles north-east) and Andover War Memorial Hospital (2.8 miles north). Open spaces near Red Rice include Mill Lake and Quarley Hill.
What happens if it’s left?
Water gets in through a failed movement joint and can run behind render or cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. In a small place like Red Rice, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

Red Rice: your questions answered
Do you work for landlords with property near Andover station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Is Red Rice in your area for external mastic?
Yes. We work across London and the South East, and Red Rice is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Why do you put foam in the joint first?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
What we can’t put right
To be straight with you, some problems need a different trade:
- Loose or hollow render, which needs re-rendering
- Damp that is not coming from the joint
- Walls that need new movement joints cut into them
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.
What we seal
- Render & cladding joints
- Concrete & block
- Copings & trims
- Joints between brick and frames
- Brickwork movement joints
- Façade panels
Signs you need external mastic in Red Rice
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Common reasons people contact us include:
- Gaps where render, brick and frames meet
- Joints where the bead has come unstuck
- Failed sealant between panels on a façade
- Brick movement joints where the sealant has split
Rented homes near Andover station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before you book
- Whether VAT is included
- Whether the sealant suits the joint
- Whether they seal over old material or remove it
- What preparation is included
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Never let anyone fill a movement joint with mortar
- Keep high-pressure jets off the joints
- Leave the joints unpainted unless we have said otherwise
- Look over the joints every year, ideally after winter
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
