About our external mastic in Farleigh
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we don’t skip that step. We work on façade panels, render & cladding joints and copings & trims, and people most often call us about failed sealant between panels on a façade and failed seals between different materials.
Outside joints can only be sealed when they’re dry, so work in Farleigh is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Each job carries a 12-month guarantee, large or small.

Common problems we fix in Farleigh
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Any of these means the joints need attention:
- Joints where the bead has come unstuck
- Hard, crazed mastic that has stopped moving
- Rigid filler in a joint that should flex
- Moss and dirt in joints with no sealant left
In the older streets around Church of St Mary the Virgin, an extension built onto an older house moves differently, and the joint between them takes the strain.

What external mastic looks like in Farleigh
With historic houses such as Addington Palace (about 2.2 miles north) nearby, there’s older building stock in the area around Farleigh as well as newer homes. Where a home is older, 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Upper Warlingham station, split movement joints are easy to miss on a rental until damp shows inside. For site and facilities teams at buildings such as Meridian High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Why deal with it now?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. In a small place like Farleigh, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

When something else is needed
It helps to know what we cannot do too:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Loose or hollow render, which needs re-rendering
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
Surfaces we seal

How it works
The work is kept neat and contained to the joints we are treating. Expect the work to take a few hours to a few days, depending on the length of joint and the access, and we tell you how long to leave it before we go. Somewhere like Farleigh needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions

Common questions in Farleigh
I let a flat near Upper Warlingham station. Can you help?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Do you cover smaller places like Farleigh?
Yes, we do. 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.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
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 and have them redone then.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
