How a job runs
Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. For a building around Heyshott, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site
- For older buildings, check the asbestos register before work
- Clear stock, furniture or equipment away from the joints
- Tell us what induction or permit system the site runs
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

How we handle mastic sealing in Heyshott
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 draught complaints from residents or tenants and damaged joints in communal entrances and corridors, across communal entrances and stairwells, window and door perimeters on blocks and external wall and movement joints. A specialist sealant contractor works differently from a general builder: in Heyshott, that means joint design, primers and backing rod as standard.
For buildings around smaller places like Heyshott, we group work so one trip covers it. Photos of each elevation help us quote accurately.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

How the quote is worked out
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Backing rod, priming and other preparation
- Distance, for remote addresses
- Quantities, in metres or numbers
- Access and working height
A quote for mastic joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.
Sending details for a quote
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- How the joints are reached, and at what height
- Drawings or a marked-up plan, if available
- The postcode of the building
- Whether an asbestos survey exists
To get a fixed quote, call the office on 01277 525 020 or email us, telling us the site location and the nature of the job. You can also send details through our quote form.
What sealant work can’t fix
Being straight saves everyone time. New sealant won’t cure:
- Leaks through the frame itself rather than the perimeter
- Leaks from above rather than through a joint
- Substrate edges that need repairing first
Not sure which it is? You can call 01277 525 020 or email us and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Communal kitchens and washrooms
- External wall and movement joints
- Balcony and threshold joints
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Shopfronts below residential blocks
What we are called out for in Heyshott
Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.
It’s worth sending us details if you spot any of the following:
- Window mastic that has split and shrunk
- Communal area joints that look neglected
- Patchy repairs in mismatched sealant
- Damp patches beside frames
Churches, halls and community buildings such as The Parish Church of St James are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
What your quote should include
- Who will actually carry out the work
- Is the sealant right for the movement and the substrate?
- Health and safety accreditation such as CHAS
- How they’ll work around occupants
Mastic sealing around Heyshott: how the place shapes the job
The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Heyshott lies roughly 46 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
Landlords with units on estates such as Holmbush Industrial Estate (to the north-west of Heyshott) can bring frame, door and external mastic across several units into one programme. Historic properties like Cowdray House, 2.5 miles north of Heyshott, show the age of some local stock, where frame mastic must suit soft brick or stone.
Heyshott is about 8 miles north of Chichester, in West Sussex. Heyshott sits inside our coverage and the rest of West Sussex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Heyshott is one of 373 places we cover in West Sussex. Portsmouth is covered too, around 19 miles from Heyshott.
Commercial sites across GU29 are covered. Nearby places we also cover include Hoyle (1 mile north-east), Heyshott Green (1 mile north-west), Cocking (1 mile west), Cocking Causeway (2 miles north-west) and West Lavington (2 miles north) for mastic joints. Bigger towns within reach include Bognor Regis (11 miles south), Chichester (8 miles south), Selsey (15 miles south), Littlehampton (13 miles south-east), Rustington (13 miles south-east) and Storrington (12 miles east).
Near you in Heyshott
We work on buildings around Unicorn Inn. Well-known places in the area include Lodsworth Castle (2.8 miles north-east) and Midhurst Community Hospital (2.9 miles north). Green spaces nearby include Graffham Common and Levin Down.
Doing it in-house
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Questions about Heyshott
Do you take on block-wide or estate-wide mastic work in Heyshott?
Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.
Is Heyshott too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn so you can plan around it.
How many days will you need on site?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Why act early in Heyshott
Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work with less control over timing. For buildings around smaller places like Heyshott, 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.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.
