External mastic in Faringdon, done properly
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. If you have hard, crazed mastic that has stopped moving and sealant that has lost its bond to the brick or render, we can help, whatever the surface.
Around Faringdon, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

How to look after the new joints
To keep the joints looking good and working properly:
- Walk round the building once a year and look at the joints
- Don’t let climbing plants root in the sealant
- Keep water from gutters off the wall
- Act on the first splits you see
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. Earlier resealing means a smaller job and a better result.
Why deal with it now?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost around the joint, so the damage spreads beyond the joint. Homes in smaller places like Faringdon can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

What we can’t put right
We won’t take on work that won’t last, so these are the limits:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracks in the bricks or render themselves, away from the joints
- Damp that isn’t coming from the joint
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
What we seal
- Copings & trims
- Joints between brick and frames
- Façade panels
- Concrete & block
- Render & cladding joints
- Brickwork movement joints
How it works
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for a handful of joints, longer for a whole elevation. For a job in Faringdon, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- 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.
Before we arrive
- Keep children and pets away from the work area
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can

Questions from Faringdon
Is external mastic in Faringdon guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Do you cover smaller places like Faringdon?
Yes, Faringdon is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
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.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you.
How much does external mastic cost in Faringdon?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces with primer where required.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

Common problems we fix in Faringdon
Sometimes a movement joint was filled with mortar or a rigid filler. The joint can’t move, so the wall cracks somewhere else instead.
Most people get in touch after spotting one of these:
- Brick movement joints where the sealant has split
- Sealant pulling away from one side of the joint
- Cracked joints where brick meets render or frames
- Weeds or debris growing in open joints
Homes close to Church of All Saints include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How the job changes by surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly if the joint can be cleared.
Faringdon buildings and the weather
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 Buscot Park (about 3 miles north-west) nearby, there’s older building stock in the area around Faringdon as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you look after a building such as Faringdon Community College, larger buildings have long runs of movement joint that eventually need resealing.
