About our mastic sealing in South Harting
For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. If you are dealing with complaints coming in block by block and damp patches beside frames, we can put it right, whatever the surface. Whoever orders the work in South Harting, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Rural conversions near places like South Harting often set modern frames into older stone, flint or brick. 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.

How the job changes by surface
Tenement and older buildings
Stone needs a neutral-cure product and we choose accordingly.
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. A planned programme suits multi-building portfolios.
What sets the cost
Your fixed quote is built from the real scope. It allows for:
- Location, for remote and island sites
- Whether old sealant has to be cut out first
- How much there is to seal
- Backing rod, priming and other preparation
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- Anything awkward about access or site hours
- Whether an asbestos survey exists
- Approximate linear metres or a joint schedule
- The type of building and who uses it
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

What else we do in South Harting
Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
FAQs: South Harting
Will you price a mastic programme across our South Harting portfolio?
Yes. Planned programmes across a building, block or estate are a core part of this service. Residents are given notice through you, and the work moves building by building.
Is South Harting too far out for you?
Not at all. South Harting is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you work for managing agents and housing associations?
Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.
How do you handle work on occupied blocks?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure.
Honest limits
Before quoting, we check that sealant is the right answer. It won’t put right:
- Broken glass or failed sealed units
- Water coming in from the roof or rainwater goods
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we will tell you honestly before you book.

Blocks and managed buildings in South Harting
Central London is about 50 miles from South Harting. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. South Harting is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.
Historic properties like Uppark (1.2 miles south-west of South Harting) show the age of some local stock, where frame mastic must suit soft brick or stone. Schools and community buildings such as Harting CofE Primary School need frame and external mastic kept sound like any building. For agents with blocks near Petersfield station, 3.7 miles north-west of South Harting, a block-wide mastic programme deals with frames, balconies and entrances in one go.

Leave it or put it right?
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. For buildings around smaller places like South Harting, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
