External Mastic in Burlington Estate
Movement joints in Burlington Estate need attention? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Gaps where render, brick and frames meet
- Plants rooting in failed movement joints
- Damp patches traced to an open external joint
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Keep water from gutters off the wall
- Walk round the building once a year and look at the joints
- Do not let climbing plants root in the sealant
- Check the sealant is paintable before painting near it
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
External mastic in Burlington Estate
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. Typical jobs include brick movement joints where the sealant has split and cracked joints where brick meets render or frames, on joints between brick and frames, concrete & block and copings & trims.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. For a home in Burlington Estate, tell us how high the joints are and how to reach the back of the building.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

What we’re called out for in Burlington Estate
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Keep an eye out for these signs:
- Failed sealant between panels on a façade
- Movement joints filled with mortar instead of sealant
- Damp patches traced to an open external joint
- Sealant pulling away from one side of the joint
If you let a flat or house near Bond Street station, outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before you book
- Whether you can choose the colour
- What insurance they hold
- Whether they seal over old material or remove it
- When the joint can take water or movement
Common questions in Burlington Estate
Is parking a problem for a job in Burlington Estate?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Can you help a landlord with a rental near Bond Street station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can a movement joint be filled with mortar?
No. Rigid materials cannot move with the wall. If it has already been filled, we can normally cut it out and reseal it.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before we start, matched as closely as the range allows.
How long does external mastic last?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Every job carries our 12-month guarantee.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
What affects the cost of external mastic
For a quick quote, just ask. The main things that affect it are:
- The number of rooms or windows
- The product the joint needs
- The number and length of the joints
- The old material and how stubborn it is
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
What we need to know
When you contact us, it’s useful to know:
- Access, such as stairs, a lift or height
- The type of property
- A few pictures by email, if you can
- Where the property is
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, phone 0345 464 0079 or send us an email.
How the visit works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In Burlington Estate, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Clear the area around the work
- Try not to wet indoor joints just before the visit
- Mention any tricky access

Related advice
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
External mastic in Burlington Estate: local notes
With historic houses such as Burlington House (about 0.1 miles south-east) nearby, there’s older building stock in the area around Burlington Estate as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking.
If you look after a building such as LITE Regal International School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Burlington Estate is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What else we do in Burlington Estate
Why act early in Burlington Estate
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Burlington Estate, the repair is bigger than the sealant job would have been.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
