Your questions about external mastic in Farnborough
I let a flat near Farnborough Main station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Is there a guarantee on external mastic in Farnborough?
All our work, in Farnborough and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
What is a movement joint?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking.
How much does external mastic cost in Farnborough?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or email us and let us know what needs doing and where.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.
How long does the job take?
That depends on how much there is to do, but as a guide it takes a few hours for a handful of joints, longer for a whole elevation. We’ll tell you when we quote.
Do you work at height?
That depends on the building and the joints. Where joints can be reached safely, we’ll do them. Tell us about the building and we will confirm what access is needed.
About our external mastic in Farnborough
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. If you are dealing with damp patches traced to an open external joint and plants rooting in failed movement joints, we can help, whatever the surface.
Farnborough mixes older houses and their gutters with newer estates of brick, render and uPVC trims. All of those joints move, so they need a flexible sealant rather than a rigid filler.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

Signs you need external mastic in Farnborough
If plants are growing out of a joint, the sealant has normally failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
If you can see any of these, it’s time to have the joints looked at:
- Joints with sealant missing in places
- Old sealant gone brittle and cracked
- Movement joints filled with mortar instead of sealant
- Moss and dirt in joints with no sealant left
For landlords with property near Farnborough Main station, outside joints that have cracked can let damp into a rental, so check them between lets.
Before booking anyone
- Which sealant they’ll use, and why
- Whether you can choose the colour
- How much experience the applicator has
- Are they insured?
For landlords and businesses
For anyone letting property in or around Farnborough, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
When it is not the sealant
We’ll always be straight with you, so here’s what new sealant will not do:
- Rising or penetrating damp from elsewhere in the wall
- Structural movement, which needs a surveyor or engineer
- Walls that need new movement joints cut into them
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before you book.
Joints and surfaces we work on
- Façade panels
- Joints between brick and frames
- Brickwork movement joints
- Copings & trims
- Render & cladding joints
- Concrete & block
Surface by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
Leave it or put it right?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together. Black mould and gaps in sealant don’t fix themselves, and in a busy home in Farnborough they get worse with every use. Now is the easy time to put it right.
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. The price is agreed before we begin.
Why book with us
- Full insurance on every job
- Anti-fungal silicone where joints get wet
- 4.9 on Google from 180+ five-star reviews

External mastic in Farnborough: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St Christopher, an extension built onto an older house moves differently, and the joint between them takes the strain. Schools such as Tower Hill Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
