Walls and rooflines in Kitwood
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 Bentworth Hall (about 3.8 miles north) are a reminder that the area around Kitwood 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.
Managing a site like Four Marks Church of England Primary School? Then 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 the Good Shepherd, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How we handle external mastic in Kitwood
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. If you have sealant pulling away from one side of the joint and weeds or debris growing in open joints, we can put it right.
Around Kitwood, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in.
Whatever the size of the job, you get the same 12-month guarantee.

Your questions about external mastic in Kitwood
What guarantee comes with external mastic in Kitwood?
All our work, in Kitwood and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Can you do external mastic in Kitwood?
Yes, Kitwood is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
How long does external mastic last?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges.
What colours does the sealant come in?
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.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What is a movement joint?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Are you insured?
Yes. We are fully insured.
What we do, step by step
There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours to a few days, depending on the length of joint and the access from start to finish. In a small place like Kitwood, access is generally 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.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit

Why it’s worth doing now in Kitwood
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Where a wall is exposed, as many are in small places like Kitwood, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- 20+ years of sealant experience
- Homes, businesses and hotels
- Colour picked to suit the job

What the job involves on each surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Subsidence or other structural problems
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracking across the wall rather than at a joint
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before booking.
Surfaces we seal
- Copings & trims
- Brickwork movement joints
- Façade panels
- Render & cladding joints
- Concrete & block
- Joints between brick and frames

What affects the quote in Kitwood
Some jobs are bigger than they look, and some smaller. The main factors:
- The product the joint needs
- Any working-time requirements on site
- How easy the joints are to reach
- Mould in or behind the old joints
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
What we need to know
What to tell us when you ask for a quote:
- Where the property is
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
For external mastic in Kitwood, phone 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
How to look after the new joints
To keep the joints looking good and working properly:
- Fix overflowing gutters above sealed joints
- Point out the joints to other trades
- Get split or bare joints resealed while the damage is small
- Make sure movement joints are not pointed over
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.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
