The process
At the end, we look at the finished work together. The visit itself generally takes anything from a few hours to several days, depending on the building, depending on how much there is to do. For a village or hamlet like Upper Chute, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before
- Tell us if parking is tricky

External mastic for homes and businesses in Upper Chute
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. We’re often asked to deal with joints where the bead has come unstuck and plants rooting in failed movement joints, on render & cladding joints, copings & trims and concrete & block.
Around Upper Chute, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.

What we are called out for in Upper Chute
Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
Signs it’s time to call us include:
- Weathered mastic that no longer stretches
- Brick movement joints where the sealant has split
- Cracked joints where brick meets render or frames
- Joints where the bead has come unstuck
In and around Upper Chute, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- What insurance they hold
- Which colour the sealant will be
- How much experience the applicator has
- What happens if they find a problem under the old sealant

Walls and rooflines in Upper Chute
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St Nicholas include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Your questions about external mastic in Upper Chute
Will you come out to Upper Chute?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Upper Chute in your area for external mastic?
Yes. We work across London and the South East, and Upper Chute is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so the joint doesn’t draw the eye.
Can you seal over the old sealant?
No. The old sealant always comes out first.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. The sealant is matched to both sides.
How much does external mastic cost in Upper Chute?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
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 do not need to watch us work.
When it isn’t the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Render that’s blown, hollow or coming away
- Cracked brickwork or render that needs a builder or plasterer
- Movement that is more than a sealant joint can take
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.
What we seal
- Concrete & block
- Façade panels
- Joints between brick and frames
- Brickwork movement joints
- Render & cladding joints
- Copings & trims
What happens if it’s left?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Older cottages and farmhouses around Upper Chute can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
