About our mastic sealing in Hassocks
Owners and agents normally inherit a building’s mastic rather than choose it and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. Site teams most often ask us about damp patches beside frames and patchy repairs in mismatched sealant, across window and door perimeters on blocks, shopfronts below residential blocks and communal kitchens and washrooms. Whoever orders the work in Hassocks, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Owners with buildings around smaller places like Hassocks often group mastic work so one visit covers several properties. Send the addresses and photos and we’ll quote for all of them together.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Advice
Block-wide mastic in Hassocks
Hassocks sits in one of the drier corners of the country, the South East. 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. Hassocks lies roughly 40 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations.
If your remit includes a building such as Hassocks Infant School, frame and door mastic can be programmed for the holidays. If you own or manage units on a site such as Victoria Business Park (1.8 miles north of Hassocks), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
Hassocks is about 2 miles south of Burgess Hill, in West Sussex. Anywhere in BN6, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 373 places in West Sussex. Our Brighton page has more on work in that area (7 miles or so).
Work on mastic joints is covered throughout BN6, for business premises of every kind. Among the streets we cover are London Road, Semley Road and Farm Close. If your building is just outside Hassocks, we cover Keymer (1 mile east), Hurst Wickham (1 mile north-west), Clayton (1 mile south), Hurstpierpoint (1 mile north-west) and Ditchling (1 mile east). Further afield, our area takes in Crawley (13 miles north), Horsham (12 miles north-west), Worthing (13 miles south-west), Haywards Heath (5 miles north-east), East Grinstead (15 miles north-east) and Shoreham-by-Sea (8 miles south-west).
Local landmarks in Hassocks
Locally, jobs take us to sites close to Downlands Community School and The Hassocks pub and the streets around them. Hassocks has its own railway station: Hassocks station. Well-known places in the area include The Budding Foundation Museum of Gardening (under half a mile south-west) and Clayton Castle (1.2 miles south). The countryside around Hassocks includes Bedelands Farm Nature Reserve and Wolstonbury Hill.
Common problems we fix in Hassocks
The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
Common reasons buildings call us in:
- The same joint failures repeated across a portfolio
- Draught complaints from residents or tenants
- Window mastic that has split and shrunk
- Movement joints with sealant missing
If you look after a block within reach of Hassocks station, less than half a mile to the south of Hassocks, frame and balcony mastic can be renewed on one programme.
What your quote should include
- What level of public liability insurance do they hold?
- Who will actually carry out the work
- Health and safety accreditation such as CHAS
- What the guarantee covers, and for how long
Cost factors for mastic joints
Quotes vary with the job. It mainly depends on:
- Working within restricted access windows
- Access and working height
- Which sealant the job calls for
- The size and state of each joint
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
What to include in your enquiry
The more we know, the firmer the quote. When you get in touch, include:
- Specification clauses that apply
- When you need the work done
- What the building is and how it’s used
- The postcode of the building
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or email a schedule or drawings.
FAQs: Hassocks
Can you work at a site such as Victoria Business Park, by Hassocks?
Yes. We cover Hassocks and the area around it, including industrial estates, business parks and retail parks such as Victoria Business Park. Photos and a short description are enough for a first look.
Is Hassocks too small for you to travel to?
No. Places such as Hassocks are covered as much as the big towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
How do you handle work on occupied blocks?
Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so you can arrange it with occupiers.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
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.
How long does a job like this take?
That varies with the scale of the job, though a typical visit usually takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we will set out a timescale with the quote.

What else we do in Hassocks
Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Protect low-level joints in entrances
- Share your contractor requirements early
- Look at the sunniest and most exposed elevations first
- Make it easy for occupiers to report draughts
Keep records of when each building was resealed. It helps plan the next round and shows what was done.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order so spending is spread.
