External & façade joints in Purbrook, Hampshire
We cover Purbrook for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Sealant that has lost its bond to the brick or render
- Failed seals between different materials
- Moss and dirt in joints with no sealant left
How we handle external mastic in Purbrook
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing. We work on concrete & block, render & cladding joints and brickwork movement joints, and people most often call us about weeds or debris growing in open joints and failed seals between different materials.
In a town like Purbrook, older houses with traditional gutters sit alongside newer estates with uPVC rooflines and rendered walls. All of those joints move, so they need a flexible sealant rather than a rigid filler.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Walls and rooflines in Purbrook
Purbrook is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, 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 John, the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like Purbrook Junior School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Bedhampton station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Purbrook is about 2 miles west of Havant, in Hampshire. Jobs in Purbrook get the same care as everywhere else we work: old sealant removed completely, careful preparation and a 12-month guarantee. 683 places in Hampshire are on our list, from the larger towns to small villages.

Purbrook: your questions answered
Do you work for landlords with property near Bedhampton station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Can you do external mastic in Purbrook?
Yes, Purbrook is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
How long does external mastic last?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Pointing it stops it working. A flexible sealant is the right fill.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
Can you reach joints on upper floors?
Each building is different. Tell us the height, the number of joints and what’s below them and we’ll confirm how they can be reached safely.
Landlords, agents and businesses in Purbrook
Landlords and agents in Purbrook can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render around the joint, so the damage spreads beyond the joint. Black mould and gaps in sealant do not fix themselves, and in a busy home in Purbrook they get worse with every use. Replacing the sealant now is the simplest fix.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Render that’s blown, hollow or coming away
- Cracked brickwork or render that needs a builder or plasterer
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

The process
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work starts. The work usually takes a few hours for a handful of joints, longer for a whole elevation. In Purbrook, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Clear the area around the work
- Mention any parking rules near the property
- Mention if the joints have been sealed before

Advice
DIY versus a professional finish
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.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Different surfaces, different methods
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap and keep the sealant to the right depth.
Cladding and façade panels
If the façade has a specified sealant, that is what we use, or one the system allows. Send us any details you have about the façade.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Keep soil, plants and ivy away from the joints
- Walk round the building once a year and look at the joints
- Keep high-pressure jets off the joints
- Leave the joints unpainted unless we’ve said otherwise
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
