External mastic for homes and businesses in Farley Green
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. If you have movement joints with cracked, split or missing sealant and weathered mastic that no longer stretches, we can help, on brickwork movement joints, render & cladding joints and joints between brick and frames alike.
Around Farley Green, 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, and they need the right sealant at the right depth.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What external mastic looks like in Farley Green
With historic houses such as Chilworth Manor (about 2.7 miles north-west) nearby, there’s older building stock in the area around Farley Green as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among 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 St Michael include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Chilworth station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Different surfaces, different methods
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. A primer goes on where the product requires one.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Clear growth from the base of walls and joints
- Deal with leaking gutters that soak the joints below
- Keep movement joints as flexible joints, not mortar
- Tell anyone working on the walls about the movement joints
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
A joint that has stopped moving pushes the movement elsewhere, generally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
How it works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to several days, depending on the building, including the tidy-up. In a small place like Farley Green, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- 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.
Preparing for the visit
- Clear the area around the work
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit

Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Older cottages and farmhouses around Farley Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

What does external mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or send us an email and tell us what needs doing and where.
Are you insured?
Yes, we’re fully insured for every job we do.
How long does the job take?
That depends on how much there is to do, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We’ll tell you when we quote.
Can you seal joints between render and window frames?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Can you reach joints on upper floors?
It depends on the building. Where joints can be reached safely, we will do them. Tell us about the building and we will confirm what access is needed.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Structural movement, which needs a surveyor or engineer
- Failed render or damaged cladding panels
- Damp that isn’t coming from the joint
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
