External & façade joints in Woodgreen, Hampshire
External mastic for Woodgreen and the surrounding area: careful preparation, the right product and tidy work. Call for a quick quote.
- Joints where the bead has come unstuck
- Joints with sealant missing in places
- Gaps where render, brick and frames meet
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
External mastic in Woodgreen, done properly
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. Typical jobs include leaking joints around cladding and façade panels and weeds or debris growing in open joints, on brickwork movement joints, joints between brick and frames and façade panels.
External sealant needs dry, clean surfaces, so work around Woodgreen is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
You get a one-year guarantee, the same in Woodgreen as everywhere else we work.

Woodgreen questions
Is external mastic in Woodgreen guaranteed?
All our work, in Woodgreen and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Woodgreen?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How much does external mastic cost in Woodgreen?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you reach joints on upper floors?
It depends on the height and the site. Ground-floor joints are simple; for higher ones, send details and we’ll confirm the access.
How long does the job take?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer, and we will tell you how long to expect.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
Landlord and commercial work in Woodgreen
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 that we can handle for you.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
Why it’s worth doing now in Woodgreen
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost around the joint, so the problem grows beyond the joint itself. Where a wall is exposed, as many are in small places like Woodgreen, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Advice
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Keep movement joints as flexible joints, not mortar
- Get split or bare joints resealed while the damage is small
- Keep high-pressure jets off the joints
- Tell anyone working on the walls about the movement joints
Give the sealant the cure time we tell you before anything rubs against it. 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.

Outside joints around Woodgreen
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. Historic houses like Breamore House (about 1.5 miles north-west) are a reminder that the area around Woodgreen has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Schools such as Breamore Church of England Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Common problems we fix in Woodgreen
Some movement joints have been pointed up with mortar by mistake. The joint cannot move, so the wall cracks somewhere else instead.
If you can see any of these, it’s time to have the joints looked at:
- Movement joints with cracked, split or missing sealant
- Plants rooting in failed movement joints
- Sealant pulling away from one side of the joint
- Hard, crazed mastic that has stopped moving
In the older streets around St Boniface, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Questions to ask before you book
- Is VAT in the price?
- How hidden problems are handled
- When the joint can take water or movement
- Whether the sealant suits the joint
