Common problems we fix in Allington
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.
It’s worth asking for a quote if you see:
- Damp patches traced to an open external joint
- Failed seals between different materials
- Moss and dirt in joints with no sealant left
- Joints where the bead has come unstuck
If you live in an older home near St. Nicholas' Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

About our external mastic in Allington
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. We are often asked to deal with gaps where render, brick and frames meet and moss and dirt in joints with no sealant left, on copings & trims, concrete & block and brickwork movement joints.
In a smaller place like Allington, some homes face open ground, and walls and rooflines facing the weather take the worst of it. Joints on those sides are usually the first to go.
Every job is covered by a one-year guarantee.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Do not let climbing plants root in the sealant
- Avoid pressure-washing directly into sealant joints
- Walk round the building once a year and look at the joints
- Leave the joints unpainted unless we have said otherwise
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
For landlords and businesses
We also work for property managers and facilities teams. Several sites can be quoted together.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
What we cannot put right
We’ll always be straight with you, so here’s what new sealant won’t do:
- Adding movement joints to masonry that has none
- Movement that’s more than a sealant joint can take
- Cracks in the bricks or render themselves, away from the joints
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.
What we seal
- Brickwork movement joints
- Copings & trims
- Joints between brick and frames
- Render & cladding joints
- Façade panels

Allington: your questions answered
Do you cover Allington for external mastic?
Yes, Allington is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
Is Allington within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for letting agents?
Yes. As well as householders, we work for landlords, agents, businesses and hotels in Allington.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.
When will the joints need doing again?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly and renew it when it starts to fail.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
How long does external mastic take?
It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on the building. We’ll tell you when we quote.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Different surfaces, different methods
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on the building. A visit to Allington is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks

Outside joints around Allington
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Stoneacre (about 4.2 miles south-east) nearby, there’s older building stock in the area around Allington as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Rented homes near Barming station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Allington Primary School, larger buildings have long runs of movement joint that eventually need resealing.
