Popley buildings and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as The Vyne (about 1.6 miles north) nearby, there’s older building stock in the area around Popley as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near Basingstoke station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as St Bede's Catholic Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to St Gabriel's Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

External mastic in Popley
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product. Typical jobs include failed seals between different materials and movement joints with cracked, split or missing sealant, across copings & trims, concrete & block and joints between brick and frames.
In and around Popley, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
Big or small, you get the same one-year guarantee.

Leave it or put it right?
Water gets in through a failed movement joint. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. In an older home around Popley, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or send us an email.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Common questions in Popley
I let a flat near Basingstoke station. Can you help?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Do you cover smaller places like Popley?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you fully insured?
Yes. Full insurance covers our work.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Pointing it stops it working, and the wall may crack nearby. A flexible sealant is the right fill.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so the joint does not draw the eye.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
What the job involves on each surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best in all weathers.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.

What else we do in Popley
The process
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take a few hours for a handful of joints, longer for a whole elevation. A visit to Popley is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Clear items away from the joints we are working on
- On commercial sites, let us know about site rules
- Mention any tricky access

Aftercare tips
To keep the joints looking good and working properly:
- Keep soil, plants and ivy away from the joints
- Check external joints each spring
- Keep movement joints as flexible joints, not mortar
- Show decorators and builders where the movement joints are
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
When it isn’t the sealant
Before booking, it’s worth knowing the limits too:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Subsidence or other structural problems
- Adding movement joints to masonry that has none
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
