External Mastic in Bledlow Ridge
We cover Bledlow Ridge for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Failed sealant between panels on a façade
- Joints pointed up with cement by mistake
- Hard, crazed mastic that has stopped moving
Surface by surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind.
About our external mastic in Bledlow Ridge
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what access is needed. If you have sealant that has lost its bond to the brick or render and panel joints letting water in, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Bledlow Ridge is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Outside joints around Bledlow Ridge
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. With historic houses such as West Wycombe Park House (about 2.9 miles south-east) nearby, there’s older building stock in the area around Bledlow Ridge as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For an older house near a landmark such as Church of St Paul, the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Saunderton station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What else we do in Bledlow Ridge
Common problems we fix in Bledlow Ridge
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Common reasons people contact us are:
- Panel joints letting water in
- Brick movement joints where the sealant has split
- Cracked joints where brick meets render or frames
- Weathered mastic that no longer stretches
If you look after a building such as Bledlow Ridge School, its movement joints, gutters and trims need looking after like any other building’s.

Bledlow Ridge: your questions answered
Can you do external mastic in Bledlow Ridge?
Yes, Bledlow Ridge is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Bledlow Ridge?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose. A flexible sealant is the right fill.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or drop us an email.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Do you work for letting agents?
Yes. We work in homes, commercial premises and hotels, and we are fully insured.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Never let anyone fill a movement joint with mortar
- Keep water from gutters off the wall
- Avoid pressure-washing directly into sealant joints
- Act on the first splits you see
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
How we quote for external mastic
You will get a clear quote before any work starts. It’s based on:
- When we can work, for business premises
- Access and height
- How many areas need sealing
- Which sealant suits the joint
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
- Any previous sealing or DIY work
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we’ll talk you through the work before giving you a price.
Leave it or put it right?
A failed movement joint lets water into the wall. Dealing with it early keeps the repair to the joint, rather than the wall around it. Around Bledlow Ridge, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Why book with us
- A 12-month guarantee on all work
- Fully insured
- A sealant colour to suit the surroundings
- Anti-fungal silicone where joints get wet
What we do, step by step
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours to a few days, depending on the length of joint and the access, including the tidy-up. Somewhere like Bledlow Ridge needs a little journey planning: 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.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky
