DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How we handle external mastic in Beenham
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. Common call-outs are for weathered mastic that no longer stretches and water getting into walls through failed joints, on joints between brick and frames, render & cladding joints and façade panels.
Outside joints can only be sealed when they’re dry, so work in Beenham is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
We stand behind the work with a one-year guarantee.

Why deal with it now?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render, so the damage spreads beyond the joint. In a small place like Beenham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

When it is not the sealant
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Movement that is more than a sealant joint can take
- Loose or hollow render, which needs re-rendering
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before you book.

What external mastic looks like in Beenham
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Letting a property close to Aldermaston station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Beenham Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

How the visit works
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. In a small place like Beenham, 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.
- 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.
Getting ready for the visit

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep high-pressure jets off the joints
- Never let anyone fill a movement joint with mortar
- Keep soil, plants and ivy away from the joints
- Have failed joints looked at early
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.
