External Mastic in Broughton Crossing
Problem with your movement joints in Broughton Crossing? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.

External mastic in Broughton Crossing
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 work on copings & trims, concrete & block and brickwork movement joints, and people most often call us about sealant that has lost its bond to the brick or render and moss and dirt in joints with no sealant left.
Older homes in small places like Broughton Crossing may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in.
You get a one-year guarantee, the same in Broughton Crossing as everywhere else we work.

What affects the quote in Broughton Crossing
Every job gets its own quote. This is what makes a difference:
- How many rooms, windows or areas are involved
- How easy the joints are to reach
- Which sealant suits the joint
- The number and length of the joints
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- The rough size of the job
- Photos by email, if that’s easy
- The problem you’ve noticed
- Where the property is
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we’ll explain what’s involved and give you a clear quote.

What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to several days, depending on the building, including the tidy-up. Somewhere as small as Broughton Crossing, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
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 fails, we can still redo it.
What we can’t put right
Before booking, it’s worth knowing the limits too:
- Loose or hollow render, which needs re-rendering
- Rising or penetrating damp from elsewhere in the wall
- Cutting new joints into brickwork, which is building work rather than sealant work
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

Your questions about external mastic in Broughton Crossing
Do you work for landlords with property near Aylesbury station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Do you cover Broughton Crossing for external mastic?
Yes, Broughton Crossing is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
How much does external mastic cost in Broughton Crossing?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
Can a movement joint be filled with mortar?
No. Rigid materials can’t move with the wall, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Is the work guaranteed?
Yes. All our work carries a 12-month guarantee.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Show decorators and builders where the movement joints are
- Deal with leaking gutters that soak the joints below
- Have failed joints looked at early
- Keep high-pressure jets off the joints
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
What happens if it’s left?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Around Broughton Crossing, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Why book with us

Walls and rooflines in Broughton Crossing
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.
If you look after a building such as Bierton Church of England Combined School, larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Aylesbury station, split movement joints are easy to miss on a rental until damp shows inside. Homes close to Church of St James include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
