Surface by surface
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
External mastic in Eastleigh
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render. If you have rigid filler in a joint that should flex and moss and dirt in joints with no sealant left, we can help, on render & cladding joints, façade panels and joints between brick and frames alike.
Around Eastleigh, outside jobs take in garage door frames, porches, gutters and trims as well as walls. Where two materials meet, they move differently, and the sealant has to allow for it.
Each job carries a 12-month guarantee.

Outside joints around Eastleigh
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as South Stoneham House (about 2.5 miles south-west) nearby, there’s older building stock in the area around Eastleigh as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Managing a site like Norwood Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Eastleigh station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

The process

It normally takes anything from a few hours to several days, depending on the building. For a job in Eastleigh, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Landlord and commercial work in Eastleigh
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Why act early in Eastleigh
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. In a family home in Eastleigh, a failed seal around a bath or a frame lets water into places you can’t see, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What we’re called out for in Eastleigh
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
The most common problems we see are:
- Panel joints letting water in
- Weeds or debris growing in open joints
- Movement joints filled with mortar instead of sealant
- Sealant pulling away from one side of the joint
Homes close to Church of the Resurrection include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Fix overflowing gutters above sealed joints
- Never let anyone fill a movement joint with mortar
- Ask before painting over external sealant
- Do not let climbing plants root in the sealant
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
