Riseden buildings and the weather
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. With historic houses such as Scotney Castle (about 1.1 miles west) nearby, there’s older building stock in the area around Riseden 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.
Homes close to Christ Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Around Riseden, as everywhere, external mastic is only as good as the preparation behind it.

External mastic in Riseden, done properly
Low-level joints can generally be done from the ground. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We work on façade panels, joints between brick and frames and render & cladding joints, and the jobs we see most are movement joints with cracked, split or missing sealant and panel joints letting water in.
Outside joints can only be sealed when they’re dry, so work in Riseden is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Surface by surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.
Common questions in Riseden
Is there a guarantee on external mastic in Riseden?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Can you do external mastic in Riseden?
Yes. We work across London and the South East, and Riseden is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. Exterior sealants come in a good range of colours.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Why act early in Riseden
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a small place like Riseden, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Movement that’s more than a sealant joint can take
- Loose or hollow render, which needs re-rendering
- Cracking across the wall rather than at a joint
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.

How it works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the building, and the area is left clean. In a small place like Riseden, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Have failed joints looked at early
- Tell anyone working on the walls about the movement joints
- Fix overflowing gutters above sealed joints
- Walk round the building once a year and look at the joints
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
