Questions from Turville Heath
Do you cover Turville Heath for external mastic?
Yes, Turville Heath is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Do you cover smaller places like Turville Heath?
Yes. Turville Heath is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
What’s an expansion joint in brickwork?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move and needs a flexible seal, not mortar.
How long does the job take?
A typical job takes anything from a few hours to several days, depending on the building, including preparation and clearing up. Your quote will say how long we expect yours to take.
Can you reach joints on upper floors?
Each building is different. Tell us the height, the number of joints and what’s below them and we will confirm how they can be reached safely.
About our external mastic in Turville Heath
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. We work on render & cladding joints, brickwork movement joints and joints between brick and frames, and common reasons people get in touch are water getting into walls through failed joints and sealant that has lost its bond to the brick or render.
In a village or hamlet like Turville Heath, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Each job carries a 12-month guarantee, large or small.

Different surfaces, different methods
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it and keep the sealant to the right depth.
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
What external mastic looks like in Turville Heath
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 Stonor Park (about 1 mile south) nearby, there’s older building stock in the area around Turville Heath as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
In and around Turville Heath, as anywhere, good external mastic starts with a clean, dry, properly prepared joint. Stonor Park, about 1 mile south, is one of the historic houses in the wider area around Turville Heath, and older homes nearby need a sealant that suits their walls.

What we can’t put right
In fairness, some problems need a different trade:
- Movement that’s more than a sealant joint can take
- Adding movement joints to masonry that has none
- Cracks in the bricks or render themselves, away from the joints

The process
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. In a small place like Turville Heath, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Get split or bare joints resealed while the damage is small
- Avoid pressure-washing directly into sealant joints
- Keep movement joints as flexible joints, not mortar
- Keep soil, plants and ivy away from the joints
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
For landlords and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Leave it or put it right?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. Where a wall is exposed, as many are in small places like Turville Heath, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

- Arbo and Everbuild products
