About our external mastic in Broad Street
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 strip the joint back and start again. Typical jobs include old sealant gone brittle and cracked and damp patches traced to an open external joint, on brickwork movement joints, joints between brick and frames and render & cladding joints.
Older homes in small places like Broad Street may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
All our work comes with a 12-month guarantee, wherever you are in Kent.

Walls and rooflines in Broad Street
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Leeds Castle (about 2.3 miles south) are a reminder that the area around Broad Street has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you let a flat or house near Hollingbourne station, outside joints that have cracked can let damp into a rental, so check them between lets.

Broad Street: your questions answered
Do you cover Broad Street for external mastic?
Yes. Our work covers London and the South East, and Broad Street is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Is Broad Street within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
How long does external mastic take?
A typical job takes a few hours to a few days, depending on the length of joint and the access, including preparation and clearing up. We will confirm how long when we quote.
Where do you work from?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is generally a movement joint. It gives the wall room to move, and it should be sealed with a flexible sealant.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Common problems we fix in Broad Street
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Most people get in touch when they notice something like this:
- Brick movement joints where the sealant has split
- Joints where the bead has come unstuck
- Weeds or debris growing in open joints
- Rain getting behind render or cladding at a joint
Historic houses such as Leeds Castle, about 2.3 miles south, show how far back building around Broad Street goes.

How we quote for external mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
- The number and length of the joints
- Whether there’s mould to deal with
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.

There’s no need for technical detail. It helps if you can tell us:

- Any previous sealing or DIY work
- Where the job is, and your postcode

How the visit works
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Broad Street, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints

Advice
What the job involves on each surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.
Keeping the joints in good condition
Looking after new joints is easy:
- Wash walls gently around the sealant
- Ask before painting over external sealant
- Act on the first splits you see
- Check external joints each spring
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
