External mastic in Cuddington, done properly
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the joint doesn’t stand out. If you have water getting into walls through failed joints and rigid filler in a joint that should flex, we can put it right, whatever the surface.
Older homes in small places like Cuddington may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Surface by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible year round.
Leave it or put it right?
A failed movement joint lets water into the wall. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Older cottages and farmhouses around Cuddington can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, 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.

Your questions about external mastic in Cuddington
Is Cuddington within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover Cuddington for external mastic?
Yes, Cuddington is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
What colours does the sealant come in?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin from the range available.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. We choose one that suits both surfaces.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you when we finish.
Honest limits
We will not take on work that won’t last, so these are the limits:
- Rising or penetrating damp from elsewhere in the wall
- Subsidence or other structural problems
- Adding movement joints to masonry that has none
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.

Cuddington buildings and the weather
With historic houses such as Nonsuch Mansion (about 0.2 miles north-east) nearby, there’s older building stock in the area around Cuddington as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Dunstan include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as Nonsuch High School for Girls are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Do you need external mastic in Cuddington?
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
It’s worth asking for a quote if you see:
- Panel joints letting water in
- Rain getting behind render or cladding at a joint
- Sealant that has lost its bond to the brick or render
- Moss and dirt in joints with no sealant left
Letting a property close to Cheam station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
What your quote should include
- Which sealant they’ll use, and why
- What guarantee comes with the work
- How hidden problems are handled
- Are they insured?
What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours to a few days, depending on the length of joint and the access. In a small place like Cuddington, access is usually the main thing to plan. 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.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
