Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Mastic sealing in Hardley
Blocks are lived in, so access and disruption have to be thought through. 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 throughout. The enquiries we see most involve repeated reactive repairs to the same buildings and old repairs sealed over failed mastic, on window and door perimeters on blocks, external wall and movement joints and communal kitchens and washrooms. Most enquiries from Hardley start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Hardley, 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.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Look at the sunniest and most exposed elevations first
- Share your contractor requirements early
- Have the asbestos survey to hand for older buildings
- Include mastic in your cyclical inspections
Keep records of when each building was resealed. That makes future programmes easier to plan and shows what was done.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
What we are called out for in Hardley
Occasionally the substrate fails, not the sealant for instance where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
Look out for the following:
- Patchy repairs in mismatched sealant
- Leaks at window and door perimeters
- The same joint failures repeated across a portfolio
- Communal area joints that look neglected
If you look after a block within reach of Netley station (3.3 miles north-east of Hardley), frame and balcony mastic can be renewed on one programme.
Questions to ask before you book
- How they’ll work around occupants
- How long is the guarantee, and what does it include?
- Who will actually carry out the work
- Is the sealant right for the movement and the substrate?
Why it’s worth doing now in Hardley
Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. For buildings around smaller places like Hardley, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Your questions answered
Will you take on a block within reach of Netley station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Is Hardley too far out for you?
Not at all. Hardley is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Do you do block-wide mastic programmes?
We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.
Looking after buildings in and around Hardley
Hardley is within about 2 miles of the coast. On buildings near the shore, the side facing the weather usually needs its mastic renewed first, so it’s worth inspecting those sides more often. Hardley is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building usually need attention first.
If you manage student housing near a university such as Southampton Solent University, 4.8 miles to the north of Hardley, the summer turnaround is the time for mastic. Landlords with units on estates such as Glenmore Business Park, less than half a mile to the north-west of Hardley, can bring frame, door and external mastic across several units into one programme.
