External & façade joints in Charleshill, Surrey
We cover Charleshill for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Joints pointed up with cement by mistake
- Failed sealant between panels on a façade
- Rain getting behind render or cladding at a joint
Why deal with it now?
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. In a small place like Charleshill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.
What you get with us
- Sealant colour chosen to suit
- Tidy, careful work
- Anti-fungal silicone where joints get wet

About our external mastic in Charleshill
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 joints with sealant missing in places and moss and dirt in joints with no sealant left, we can put it right, on concrete & block, render & cladding joints and façade panels alike.
Outside joints can only be sealed when they’re dry, so work in Charleshill is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
A 12-month guarantee comes as standard.

How the job changes by surface
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
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and protects the render itself.
Signs you need external mastic in Charleshill
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
If you can see any of these, it’s time to have the joints looked at:
- Damp patches traced to an open external joint
- Brick movement joints where the sealant has split
- Rigid filler in a joint that should flex
- Weeds or debris growing in open joints
For an older house near a landmark such as Church of St James, an extension built onto an older house moves differently, and the joint between them takes the strain.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take anything from a few hours to several days, depending on the building. Somewhere like Charleshill needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height

External mastic in Charleshill: local notes
The South East is one of the drier parts 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 Farnham Castle (about 3.8 miles north-west) nearby, there’s older building stock in the area around Charleshill as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For landlords with property near Farnham station, outside joints that have cracked can let damp into a rental, so check them between lets. Managing a site like Waverley Abbey CofE Junior School? Then its movement joints, gutters and trims need looking after like any other building’s.

For landlords and businesses
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Never let anyone fill a movement joint with mortar
- Check the sealant is paintable before painting near it
- Fix overflowing gutters above sealed joints
- Keep soil, plants and ivy away from the joints
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.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick.
