Common problems we fix in Hammer
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears.
Site and facilities staff are often the first to spot these:
- Spalled or broken joint edges in floors and decks
- Sealant peeling off one face of the joint
- Joints packed with grit and debris
- Weathered movement joint sealant that no longer flexes
Hospital campuses such as Holy Cross Hospital (to the north-east of Hammer) grow in stages, leaving movement joints wherever new blocks meet old.
What to look for in a quote
- Whether primer will be used where the manufacturer specifies it
- Can the work be phased to keep areas open?
- Their approach to joint depth and backing
- Will failed sealant be removed rather than covered?
About our expansion joint sealing in Hammer
Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it and we name it in the quote. We work on precast concrete panel joints, blockwork control joints and brickwork movement joints, and the failures we are asked to look at most are movement joints with split or torn sealant and spalled or broken joint edges in floors and decks. Whether you call it commercial sealant work, mastic application or joint sealing, in Hammer it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For a site near Hammer, measurements and photos up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we will take it from there.
A 12-month guarantee applies to all our work in West Sussex. Should something we installed fail, give us a call on 01277 525 020 or send photos by email and we will come back to it.

What else we do in Hammer
Questions we are asked in Hammer
Is a smaller place like Hammer outside your area?
Not at all: smaller places are covered as well as towns. 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.
Do you cover business parks and estates near Hammer, such as Kings Road Industrial Estate?
Yes. Estates, retail parks and business parks around Hammer, Kings Road Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Can the sealant be colour-matched?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
What if the joint edges are damaged?
A bond is only as strong as the material behind it, so broken or crumbling edges have to be repaired first. We flag it at the quote stage where we can see it.
What do you charge?
Each job is quoted on its own details. To get one, phone 01277 525 020 or email a schedule or drawings.
Does the weather affect joint sealing?
The joint has to be dry, and the air and surface temperature inside the product’s limits. Cold, damp or frosty mornings can stop work outside so external dates keep some flexibility.
After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Plan racking layouts so feet don’t land on a joint
- Note which joints were done, when, and with what
- Reopen bays and walkways only after the stated cure time
- Keep scrapers and ploughs from dragging across joint sealant
In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines, and report any chipped edges early.
On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Resealing early limits the damage.
Surface by surface
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.
Car park decks and ramps
Car park joints are some of the hardest-working joints in any building. A trafficable sealant suited to the movement goes in, phased so parts of the car park stay open.
What happens if it’s left?
On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open. Tell us what has to stay open and we’ll plan around it. One visit to deal with every failing joint makes more sense than several trips to a place like Hammer. Photos of every joint help us quote for the whole job.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Slabs, ramps and loading bays in Hammer
Rainfall across the South East, Hammer included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open. Less than 3 miles from Hammer there are two named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.
Schools such as Woolmer Hill School have movement joints in their walls and floors that are easy to overlook. On industrial estates such as Kings Road Industrial Estate, 1 mile to the east of Hammer, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
Hammer is about 9 miles south of Farnham, in West Sussex. Any commercial site in Hammer is covered, for single jobs and planned programmes alike. We work across 373 places in West Sussex, from busy centres to rural villages. Portsmouth is covered too, around 24 miles from Hammer.
Business premises anywhere in GU27 are within our area. Among the streets we cover are Hammer Lane, Moor Road and Copse Road. We also cover Woolmer Hill (1 mile south), Hammer Bottom (1 mile west), Shottermill (1 mile east), Bramshott Chase (1 mile north) and Linchmere (1 mile south-west) for movement joints. A short drive away, we cover Billingshurst (14 miles east), Midhurst (7 miles south), Pulborough (14 miles south-east), Petworth (9 miles south-east), Easebourne (6 miles south) and Fernhurst (3 miles south-east).
Near you in Hammer
We work on buildings around The Prince of Wales pub and Camelsdale Primary School and the streets around them. For rail, the closest station is Haslemere station, roughly 1.5 miles east. Other landmarks nearby include Haslemere and District Hospital (2 miles east). For a walk, there’s Lynchmere Commons and Wheeler's Down.
From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Hammer are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- Next, we fix a price and confirm the sealant we propose for the movement.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Finished joints are checked and backed by our 12-month guarantee.
Before we start on site
- Have the specification and drawings to hand
- Warn occupants and staff about the work
- Move anything stored against the joints
