External mastic for homes and businesses in Winklebury
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. If you have plants rooting in failed movement joints and sealant pulling away from one side of the joint, we can put it right, on brickwork movement joints, copings & trims and concrete & block alike.
In a smaller place like Winklebury, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are usually the first to go.
Every job comes with our one-year guarantee, wherever you are in Hampshire.

Surface by surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap so the sealant is not too deep.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
Winklebury 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 3 miles north-east) nearby, there’s older building stock in the area around Winklebury 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 Castle Hill Infant School? Then its movement joints, gutters and trims need looking after like any other building’s. The Vyne, about 3 miles north-east, is one of the historic houses in the wider area around Winklebury, and older homes nearby need a sealant that suits their walls. For landlords with property near Basingstoke station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Quotes for external mastic in Winklebury
There’s no set price list, because no two jobs are the same. The quote depends on:
- Whether the work is at height
- The number and length of the joints
- Any working-time requirements on site
- The type of sealant required
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 the work is at height. Your quote takes all of that into account.

You don’t need to know the technical terms. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- Roughly how big the job is
- If someone has resealed it before
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you’re ready, ring 0345 464 0079 or drop us an email.

How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the building. A visit to Winklebury 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 inspect the joints and agree which need resealing and how they’ll be reached.
- 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.
How to prepare
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area

Related advice
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, 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 call for the right materials, safe access and experience.
Winklebury questions
Is Winklebury within the area you cover?
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.
I let a flat near Basingstoke station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Where do you work from?
We work from Crawley. Our applicators cover Winklebury, along with the rest of our area.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
How long before the joint can be used?
It depends on the product. We tell you how long to leave it before we go.
Is there any odour?
Some sealants have a smell while they cure. Opening a window helps.
How much does external mastic cost in Winklebury?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or email us with a short description of the job.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access.
Why it’s worth doing now in Winklebury
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together and it means sorting access once. In an older home around Winklebury, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
