About our external mastic in Heath End
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. If you’re dealing with failed sealant between panels on a façade and movement joints filled with mortar instead of sealant, we can put it right, on render & cladding joints, concrete & block and brickwork movement joints alike.
Around Heath End, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

Leave it or put it right?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. Where a wall is exposed, as many are in small places like Heath End, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

We’ll always be straight with you, so here’s what sealant cannot fix:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Structural movement, which needs a surveyor or engineer

How it works
Before we leave, we go over the finished joints with you. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. In a small place like Heath End, access is generally 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.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height

Advice
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Heath End: your questions answered
Do you cover smaller places like Heath End?
Yes, Heath End is covered. 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.
Do you work for landlords with property near Aldershot station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Can you reach joints on upper floors?
It depends on the building. We work on joints that can be reached safely. Give us some details and we’ll confirm the access.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Common problems we fix in Heath End
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Look out for these signs:
- Weathered mastic that no longer stretches
- Water getting into walls through failed joints
- Movement joints with cracked, split or missing sealant
- Sealant pulling away from one side of the joint
Rented homes near Aldershot station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Different surfaces, different methods
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
What external mastic looks like in Heath End
With historic houses such as Farnham Castle (about 1.4 miles south-west) nearby, there’s older building stock in the area around Heath End as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Farnham Heath End School? Then larger buildings have long runs of movement joint that eventually need resealing. In the older streets around St Mark the Evangelist Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
