I let a flat near Witley station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.

How long does the job take?
A typical job takes anything from a few hours to several days, depending on the building, including the preparation. Your quote will say how long we expect yours to take.
Do you work at height?
It depends on the building. Tell us the height, the number of joints and what’s below them.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
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.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.

Low-level joints can generally be done from the ground. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. Common call-outs are for old sealant gone brittle and cracked and sealant pulling away from one side of the joint, across façade panels, joints between brick and frames and concrete & block.

How the visit works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take anything from a few hours to several days, depending on the building. In a small place like Bowlhead Green, access is normally 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.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
- Keep children and pets away from the work area

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Do you need external mastic in Bowlhead Green?
Every building moves. 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.
Look out for any of the following:
- Sealant pulling away from one side of the joint
- Plants rooting in failed movement joints
- Failed seals between different materials
- Movement joints with cracked, split or missing sealant
In the older streets around Church of St Michael and All Angels, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- How hidden problems are handled
- Who does the work, and how experienced they are
- Which colour the sealant will be
- Are they insured?

Why act early in Bowlhead Green
Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Where a wall is exposed, as many are in small places like Bowlhead Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
