External & façade joints in Norleywood, Hampshire
Movement joints in Norleywood need attention? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Failed seals between different materials
- Water getting into walls through failed joints
- Joints where the bead has come unstuck
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
About our external mastic in Norleywood
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the joint does not stand out. If you have gaps where render, brick and frames meet and damp patches traced to an open external joint, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Norleywood is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Our work is backed for twelve months.

Surface by surface
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible.
Your questions about external mastic in Norleywood
I let a flat near Lymington Pier station. Can you help?
Yes. We work for landlords and agents as well as householders. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Does living near the coast affect external mastic in Norleywood?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can a movement joint be filled with mortar?
No. A mortar-filled joint cannot move, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Why it’s worth doing now in Norleywood
Sealing over the top of old mastic does not hold for long. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. Older cottages and farmhouses around Norleywood can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.

Walls and rooflines in Norleywood
Norleywood 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. Historic houses like Beaulieu Palace House (about 3.5 miles north-east) are a reminder that the area around Norleywood 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.
For site and facilities teams at buildings such as South Baddesley Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing. In the older streets around Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move. Letting a property close to Lymington Pier station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What sealant work can’t fix
Sealant is not the answer to every problem, and we’ll tell you before any work starts. It won’t solve:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Loose or hollow render, which needs re-rendering
- Subsidence or other structural problems
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Façade panels
- Brickwork movement joints
- Concrete & block

- Joints between brick and frames
How the visit works
We keep the work tidy and contained to the joints we’re treating. Expect the work to take a few hours for a handful of joints, longer for a whole elevation. In a small place like Norleywood, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- 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.
How to prepare
- Mention any tricky access
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks

Looking after it afterwards
After the cure time, these simple habits help:
- Ask before painting over external sealant
- Walk round the building once a year and look at the joints
- Fix overflowing gutters above sealed joints
- Keep movement joints as flexible joints, not mortar
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges over time.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
