External mastic for homes and businesses in Peasemore
Low-level joints can generally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. We work on brickwork movement joints, copings & trims and render & cladding joints, and people most often call us about failed sealant between panels on a façade and cracked joints where brick meets render or frames.
Outside joints can only be sealed when they’re dry, so work in Peasemore is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid pressure-washing directly into sealant joints
- Do not let climbing plants root in the sealant
- Get split or bare joints resealed while the damage is small
- Walk round the building once a year and look at the joints
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
FAQs for Peasemore
Do you cover Peasemore for external mastic?
Yes, Peasemore is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear quote.
What guarantee comes with external mastic in Peasemore?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can you reach joints on upper floors?
It depends on the building. Tell us the height, the number of joints and what’s below them, and we’ll confirm what access is needed.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you.
Peasemore buildings and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Barnabas include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Why it’s worth doing now in Peasemore
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last, so it pays to do it properly once. Around Peasemore, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.

What happens on the day
At the end, we look at the finished work together. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the amount of work. Somewhere as small as Peasemore, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
Before we arrive
- Mention any tricky access
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
What sealant work cannot fix
We will not take on work that will not last, so these are the limits:
- Cracked brickwork or render that needs a builder or plasterer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Movement that is more than a sealant joint can take
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before booking.
What we seal
- Concrete & block
- Copings & trims
- Render & cladding joints
- Brickwork movement joints
- Façade panels
- Joints between brick and frames
Common problems we fix in Peasemore
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Signs it’s time to call us include:
- Joints with sealant missing in places
- Weeds or debris growing in open joints
- Cracked joints where brick meets render or frames
- Joints where the bead has come unstuck
In and around Peasemore, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- What happens if the job turns out different
- Whether all the old sealant comes out first
- How long to leave it before use
- How much experience the applicator has
