FAQs: Hassocks
Is hospital work, at somewhere like The Dene Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Is Victoria Business Park, near Hassocks, within your area?
Yes. We cover Hassocks and the area around it, including industrial estates, business parks and retail parks such as Victoria Business Park. A few photographs and the unit address let us price the work.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
What happens if it rains on the day?
Weather matters for any external joint. Internal floor joints are far less affected.
Can you send site paperwork?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
What guarantee do you give on joint sealing?
The workmanship is guaranteed for 12 months from sign-off. Keeping joints clear of debris helps them last.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
About our expansion joint sealing in Hassocks
Long runs of brick or block have movement joints built in. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. If you have layers of sealant in a movement joint and expansion joints split through the centre of the bead, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in Hassocks, that means joint design, primers and backing rod as standard.
Work in a smaller place like Hassocks is usually one building at a time. That way the right materials come on the day and the job is done in one visit where possible.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

On site: what to expect
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Work in places the size of Hassocks is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.
- We assess the joints on site or from photos, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
What we need from you
- Tell us which areas need to stay in use
- Move anything stored against the joints
- Tell us your opening times and when work is allowed

Why act early in Hassocks
Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now. We can split the scope into urgent and planned. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
Why us?
- Joints cleaned back to sound surfaces
- Health and safety: CHAS accredited
- Constructionline member for supplier checks
- 12 months’ guarantee on every job

What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Cracking or settlement that calls for an engineer’s assessment
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
If you are not sure, just give us a call on 01277 525 020 or email the details over and we will give you a straight answer.

What else we do in Hassocks
Owners, agents and contractors
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Hassocks can sit alongside others in a wider programme.
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.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Expansion joint sealing in Hassocks: the local picture
Hassocks is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint. At about 40 miles from central London, Hassocks is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift.
In a school such as Hassocks Infant School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Business parks such as Victoria Business Park (to the north of Hassocks) have car parks, paved areas and long brick and panel elevations, all with movement joints.
Hassocks is about 2 miles south of Burgess Hill, in West Sussex. We cover commercial sites throughout Hassocks. Hassocks is one of 373 places in West Sussex on our list for movement joints. Our Brighton page has more on work in that area (7 miles or so).

When to call us in Hassocks
When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons and it often shows on rushed work.
What tends to prompt an enquiry:
- Leaks through car park deck joints onto the level below
- Brittle, chalky sealant on external joints
- Debris jammed in movement joints
- Water getting into the wall through a failed joint
University campuses such as University of Sussex, 4.9 miles south-east of Hassocks, have car parks, paved walkways and building elevations with movement joints.
