Sutton at Hone questions
Can you do external mastic in Sutton at Hone?
Yes, Sutton at Hone is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Can you help a landlord with a rental near Farningham Road station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.
Can you reach joints on upper floors?
It depends on the height and the site. Ground-floor joints are simple; for higher work, tell us about the building and we’ll confirm what’s needed.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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, then guaranteed for a year.

External mastic in Sutton at Hone: local notes
Rainfall in the South East is lower than in much 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 Lullingstone Castle (about 3.9 miles south-west) nearby, there’s older building stock in the area around Sutton at Hone as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near Farningham Road station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around Church of St John the Baptist, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. Somewhere like Sutton at Hone needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in

Why deal with it now?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Around Sutton at Hone, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and send you a clear quote before we start.
Why us?
- Colour picked to suit the job
- Colour agreed with you before any work starts
- Any old sealant cut out fully, not covered over
- More than 20 years in sealant work
For landlords and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
When to call us in Sutton at Hone
Sometimes a movement joint was filled with mortar or a rigid filler. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
These are the problems we are asked about most:
- Rigid filler in a joint that should flex
- Brick movement joints where the sealant has split
- Sealant that has lost its bond to the brick or render
- Weathered mastic that no longer stretches
For site and facilities teams at buildings such as Sutton-At-Hone Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s.
What to look for in a quote

When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Adding movement joints to masonry that has none
- Subsidence or other structural problems
- Cracked brickwork or render that needs a builder or plasterer
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.
