External mastic for homes and businesses in Warblington
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the joint does not stand out. We’re often asked to deal with brick movement joints where the sealant has split and weathered mastic that no longer stretches, on concrete & block, render & cladding joints and façade panels.
Outside joints can only be sealed when they’re dry, so work in Warblington is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Your job is guaranteed for a year, as with all our work.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Look over the joints every year, ideally after winter
- Clear growth from the base of walls and joints
- Deal with leaking gutters that soak the joints below
- Wash walls gently around the sealant
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted and spoil the finish.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
Your questions about external mastic in Warblington
Do you work for landlords with property near Warblington station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Is Warblington within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so it does not stand out.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
What happens if it’s left?
Sealing over the top of old mastic doesn’t hold for long. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. In a small place like Warblington, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

What affects the quote in Warblington
We quote each job individually. These are the things that affect it:
- The number and length of the joints
- The number of rooms or windows
- Any mould that needs treating
- Working hours on commercial sites
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- If someone has resealed it before
- Where the property is
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
There’s no standard price list. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or drop us an email.
Signs you need external mastic in Warblington
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.
Keep an eye out for these signs:
- Leaking joints around cladding and façade panels
- Movement joints with cracked, split or missing sealant
- Damp patches traced to an open external joint
- Weathered mastic that no longer stretches
Managing a site like Bosmere Junior School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What to look for in a quote
- How hidden problems are handled
- What the cure time is
- What guarantee comes with the work
- Whether the sealant suits the joint
DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What happens on the day
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In a small place like Warblington, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules

Surface by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.

Warblington buildings and the weather
Warblington is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near St Thomas à Becket Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you let a flat or house near Warblington station, split movement joints are easy to miss on a rental until damp shows inside.
