About our mastic sealing in Worthy Down
For blocks and buildings in Worthy Down and across Hampshire, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote or we can visit. We work on balcony and threshold joints, window and door perimeters on blocks and external wall and movement joints, and what we’re called in for most is patchy repairs in mismatched sealant and open joints in brickwork or panels. One point of contact handles commercial sealant work in Worthy Down from the first photos to the final walk-round, for single jobs and planned programmes alike.
In and around smaller places like Worthy Down, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

When to call us in Worthy Down
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone, so these repairs rarely last.
These are often picked up first by site or facilities staff:
- Old repairs sealed over failed mastic
- Complaints coming in block by block
- Communal area joints that look neglected
- Cracked, hardened mastic round windows on a block
If your remit includes a building such as South Wonston Primary School, frame and door mastic can be programmed for the holidays.
Questions to ask before you book
- What the guarantee covers, and for how long
- Is the sealant right for the movement and the substrate?
- Whether old or failed sealant will be cut out, not overlaid
- How the joint faces will be prepared and primed
Blocks and managed buildings in Worthy Down
Worthy Down lies roughly 60 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. Worthy Down is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
Student accommodation around universities such as University of Winchester, 3.5 miles south of Worthy Down, is normally managed block by block, which suits a planned mastic programme. For owners of several units at places like Beeches Industrial Park, which lies west of Worthy Down, one programme can deal with frame and external mastic across the lot.
Worthy Down is about 4 miles north of Winchester, in Hampshire. We send applicators to Worthy Down for mastic joints, handled exactly as we handle every other area. Our Hampshire coverage takes in 723 places, large and small. Sites around Southampton have their own page, about 14 miles away.

What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Frames that are rotten, warped or broken
- Broken glass or failed sealed units
If you’re not sure, just give us a call on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.
What we seal
- Communal kitchens and washrooms

Leave it or put it right?
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. Halls, stores and units around places like Worthy Down may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
What you get with us
- Health and safety: CHAS accredited
- Over 20 years of commercial sealing
- Products installed to the manufacturer’s instructions
- RAL and finish matching where the product range allows

Questions we are asked in Worthy Down
Is a smaller place like Worthy Down outside your area?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you quote for a block close to Winchester station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you seal joints high up on a block?
Every block is different. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
Do you check for asbestos in old sealant?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Related advice
Maintenance after handover
Problems stay small when the joints are checked regularly. In particular:
- Prioritise elevations facing the weather
- Protect low-level joints in entrances
- Mention RAMS, insurance or CSCS requirements up front
- Make mastic part of routine maintenance checks
Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.
One failed perimeter usually means others on the same building are close so a single failure is a sign to check the rest. Doing them together saves going back again and again.
