Common questions in West Liss
Do you work for landlords with property near Liss station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Is West Liss in your area for external mastic?
Yes. Our work covers London and the South East, and West Liss is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. There’s a wide choice of exterior colours.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
External mastic in West Liss, done properly
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing. Typical jobs include failed sealant between panels on a façade and movement joints filled with mortar instead of sealant, on concrete & block, façade panels and joints between brick and frames.
Older homes in small places like West Liss may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
Whatever the size of the job, it’s backed by our one-year guarantee.

The process
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the building. Somewhere as small as West Liss, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
- Move anything stored near the joints

How the job changes by surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Ask before painting over external sealant
- Wash walls gently around the sealant
- Make sure movement joints aren’t pointed over
- Act on the first splits you see
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
Walls and rooflines in West Liss
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.
If you look after a building such as Liss Infant School, larger buildings have long runs of movement joint that eventually need resealing. Homes close to Church of St Mary include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. For landlords with property near Liss station, outside joints that have cracked can let damp into a rental, so check them between lets.

Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Where a wall is exposed, as many are in small places like West Liss, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

Quotes for external mastic in West Liss
Jobs vary more than people expect. What affects the quote:
- Which sealant suits the joint
- The old material and how stubborn it is
- Any working-time requirements on site
- The amount of work
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.

There’s no need for technical detail. Just tell us:
- Photos by email, if that’s easy

- If it’s domestic, commercial or a hotel
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you’re ready, phone 0345 464 0079 or send us an email.
