External mastic in Dibden Purlieu, done properly
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. If you’re dealing with joints with sealant missing in places and damp patches traced to an open external joint, we can help.
Around Dibden Purlieu, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

When something else is needed
New sealant can’t fix everything, and we’ll tell you before we start. It will not solve:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp that isn’t coming from the joint
- Cracks in the bricks or render themselves, away from the joints
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
Joints and surfaces we work on
- Joints between brick and frames
- Render & cladding joints
- Concrete & block
- Brickwork movement joints
- Façade panels
- Copings & trims
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How we quote for external mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- How many areas need sealing
- When we can work, for business premises
- The amount of work
- Any mould that needs treating
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Roughly how big the job is
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- If it’s domestic, commercial or a hotel

Questions from Dibden Purlieu
Does living near the coast affect external mastic in Dibden Purlieu?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Do you work for landlords with property near Southampton Town Quay station?
Yes. We work for landlords and letting agents as well as householders. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you come to Dibden Purlieu?
Yes. We work in Dibden Purlieu and the rest of Hampshire. To book, ring 0345 464 0079 or send us an email.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
Can you reach joints on upper floors?
It depends on the height and the site. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Are you fully insured?
Yes. We’re fully insured.
What we’re called out for in Dibden Purlieu
If plants are growing out of a joint, the sealant has usually failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
Any of these means the joints need attention:
- Failed sealant between panels on a façade
- Moss and dirt in joints with no sealant left
- Rigid filler in a joint that should flex
- Hard, crazed mastic that has stopped moving
For an older house near a landmark such as St. Andrew's Church and Centre, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What external mastic looks like in Dibden Purlieu
Dibden Purlieu is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Beaulieu Palace House (about 2.9 miles south-west) are a reminder that the area around Dibden Purlieu has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Schools such as Wildground Infant School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Southampton Town Quay station, split movement joints are easy to miss on a rental until damp shows inside.

Looking after it afterwards
Looking after new joints is easy:
- Check external joints each spring
- Get split or bare joints resealed while the damage is small
- Keep soil, plants and ivy away from the joints
- Avoid pressure-washing directly into sealant joints
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.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours to a few days, depending on the length of joint and the access. A visit to Dibden Purlieu is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- 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.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Tell us if parking is tricky
