How we handle facade sealing in South Wonston
We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure for clients around South Wonston. Where sealant is the specified fix, we also take on coping and flashing joints. We work on perimeter joints where frames meet the structure, coping and flashing joints and window and door perimeters, and the failures we’re asked to look at most are weathered facade joints that have lost their grip and perimeter joints where frames meet the structure. Whether you call it commercial sealant work, mastic application or joint sealing, in South Wonston it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like South Wonston, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Why act early in South Wonston
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts. Converted and older buildings near places like South Wonston tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Why appoint us
- A Constructionline member, so easy to vet
- Our applicators hold CSCS cards
- A range of standard colours, depending on the product
- Matching to RAL references, product permitting

What affects the price in South Wonston
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Induction, permit and paperwork requirements
- How much existing material needs removing
- How much there is to seal
- Distance, for remote addresses
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
Details that help us quote
To price the job accurately, we need a clear picture of the site. Useful things to include:
- Any dates the work must fit around
- Drawings or a marked-up plan, if available
- Any specification or named product
- How the joints are reached, and at what height
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or email drawings and photos.

Owners, agents and contractors
We work for building owners and managing agents on everything from one building to a spread of sites around South Wonston. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in South Wonston can sit alongside others in a wider programme.
Aftercare for building managers
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Brief window cleaners about newly sealed joints
- Combine resealing with other works that need access
- Avoid patch repairs on failed facade joints
- Keep the sealant details on the building file
Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration.
Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading.
Facade sealing around South Wonston: what changes locally

Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.

School extensions, at buildings such as South Wonston Primary School, typically run to the summer holidays, mastic included.

What we can’t put right
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Joints whose design needs changing by the specifier
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Replacing glass or failed glazing units
If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.
