External mastic for homes and businesses in Broomfield
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. We work on brickwork movement joints, render & cladding joints and concrete & block, and the jobs we see most are sealant pulling away from one side of the joint and old sealant gone brittle and cracked.
External sealant needs dry, clean surfaces, so work around Broomfield is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Big or small, it’s backed by our 12-month guarantee.

What we do, step by step
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. Somewhere as small as Broomfield, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Let us know about stairs, lifts or work at height
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive

More services for Broomfield
Do you need external mastic in Broomfield?
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
The most common problems we see are:
- Movement joints filled with mortar instead of sealant
- Panel joints letting water in
- Sealant pulling away from one side of the joint
- Hard, crazed mastic that has stopped moving
Letting a property close to Hollingbourne station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Questions from Broomfield
Can you help a landlord with a rental near Hollingbourne station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Is Broomfield within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
How do you reach high-level joints?
It depends on the building. We work on joints that can be reached safely. Give us some details and we will confirm the access.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Adding movement joints to masonry that has none
- Render that’s blown, hollow or coming away
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.
Where we work in Broomfield
- Joints between brick and frames
- Concrete & block
- Copings & trims
- Brickwork movement joints
- Façade panels
- Render & cladding joints
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Keep high-pressure jets off the joints
- Walk round the building once a year and look at the joints
- Make sure movement joints are not pointed over
- Have failed joints looked at early
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
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, all bigger jobs than a reseal.
For landlords and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured for the work.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
How we quote for external mastic
There’s no set price list, because no two jobs are the same. What we look at:
- How many areas need sealing
- How much there is to do
- When we can work, for business premises
- Mould in or behind the old joints
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
What to tell us when you ask for a quote:
- Any access issues, like height or stairs
- The rough size of the job
- The address or postcode of the job
- If it’s domestic, commercial or a hotel

External mastic in Broomfield: local notes
With historic houses such as Leeds Castle (about 0.4 miles north-west) nearby, there’s older building stock in the area around Broomfield as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Leeds and Broomfield Church of England Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as Church of St Margaret, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Should I try it myself first?
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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
