Great Shoddesden External Mastic
Our applicators work in Great Shoddesden on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Cracked joints where brick meets render or frames
- Plants rooting in failed movement joints
- Sealant that has lost its bond to the brick or render
External mastic for homes and businesses in Great Shoddesden
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render. Typical jobs include plants rooting in failed movement joints and weathered mastic that no longer stretches, on concrete & block, brickwork movement joints and façade panels.
Somewhere as small as Great Shoddesden, homes and farm buildings often face open ground, 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.
We stand behind the work with a 12-month guarantee.

Why it’s worth doing now in Great Shoddesden
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last. In a small place like Great Shoddesden, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.

Walls and rooflines in Great Shoddesden
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.
Schools such as Ludgershall Castle Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Great Shoddesden questions
I let a flat near Grateley station. Can you help?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Do you cover Great Shoddesden for external mastic?
Yes. Our work covers London and the South East, and Great Shoddesden is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Can you reach joints on upper floors?
It depends on the building. Where joints can be reached safely, we will do them. Tell us about the building and we’ll confirm what access is needed.
How much does external mastic cost in Great Shoddesden?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or drop us an email and tell us what needs doing and where.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
When will the joints need doing again?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
What affects the cost of external mastic
For a quick quote, just ask. What matters most is:
- The product the joint needs
- Whether the work is at height
- Any working-time requirements on site
- Whether there’s mould to deal with
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
Asking for a quote
What to tell us when you ask for a quote:
- Pictures of the joints, sent by email
- Any access issues, like height or stairs
- The rough size of the job
- Whether it has been sealed before
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved and send you a clear quote.
Work for landlords, hotels and businesses
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.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will give you a quote.
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Look over the joints every year, ideally after winter
- Never let anyone fill a movement joint with mortar
- Ask before painting over external sealant
- Avoid pressure-washing directly into sealant joints
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

Signs you need external mastic in Great Shoddesden
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
The problems people usually mention when they call are:
- Moss and dirt in joints with no sealant left
- Gaps where render, brick and frames meet
- Joints pointed up with cement by mistake
- Water getting into walls through failed joints
If you let a flat or house near Grateley station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Questions to ask before booking
- Which colour the sealant will be
- Whether the sealant suits the joint
- How long the guarantee is
- What insurance they hold
What we do, step by step
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. In a small place like Great Shoddesden, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Mention any tricky access
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
