About our mastic sealing in Kings Worthy
On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Communal entrances and stairs stay usable while we work. Most enquiries involve worn sealant at communal door frames and water getting in round frames after rain, across external wall and movement joints, communal entrances and stairwells and window and door perimeters on blocks. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Kings Worthy 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 Kings Worthy, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

For owners and agents in Kings Worthy
Kings Worthy is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Central London is about 59 miles from Kings Worthy. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
Trustees of buildings like Church of St Mary can bring frame and external mastic into a planned maintenance list. Blocks of flats and mixed-use buildings often cluster around stations such as Winchester station (to the south-west of Kings Worthy) and their window and balcony mastic tends to age at the same rate across a building.

Honest limits
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Leaks through the frame itself rather than the perimeter
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Asbestos-containing sealant, which we don’t remove
If you are not sure, just speak to us on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Shopfronts below residential blocks
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Balcony and threshold joints
- External wall and movement joints
- Window and door perimeters on blocks
Looking after the joints
Cleaning and maintenance staff play a part too. Pass these on to them:
- Prioritise elevations facing the weather
- Check the asbestos register before any old mastic is disturbed
- Avoid piecemeal callouts where you can
- Share your contractor requirements early
Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first.
Your questions answered
Is a smaller place like Kings Worthy outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Do you cover business parks and estates near Kings Worthy, such as Moorside Retail Park?
Yes. Our area takes in Kings Worthy and its surroundings, with estates and business parks such as Moorside Retail Park included. A few photographs and the unit address let us price the work.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
What will the job cost?
Every job gets its own fixed quote. For yours, phone 01277 525 020 or send photos by email.
Can you plan resealing across several buildings?
We can. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Why act early in Kings Worthy
Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work and less choice about when. Older rural buildings around Kings Worthy move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
