What the job involves on each surface
Cladding panel joints
We confirm what access is in place before pricing. Photos taken near the joints help us price accurately.
Podium joints
Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal.
How we handle expansion joint sealing in Portfield
A movement joint only works while its seal does. Once it fails, water, grit and debris get in; the joint jams, its edges take the load and the arrises spall. Resealing at the first signs of failure is far cheaper than repairing the material either side. Most enquiries involve weathered movement joint sealant that no longer flexes and expansion joints split through the centre of the bead, across car park decks and ramps, brickwork movement joints and cladding panel joints. A specialist sealant contractor works differently from a general builder: on jobs in Portfield, preparation and product choice get the time they need.
In a smaller place such as Portfield, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Their slabs and walls still need movement joints that work.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

At about 54 miles from central London, Portfield is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds. Portfield has at least three named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

For estates staff at a university like University of Chichester, which lies north-west of Portfield, building and paving joints are part of the planned maintenance list.

Our process
The first thing on site is a walk round with your contact, 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. For a job in Portfield, the main thing is a clear picture of the work, so send photos of each area. A fixed quote follows.
- First, the joints are inspected for width, movement and the type of failure.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
- 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.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Before we start on site
- Let building users know which areas are affected
- Arrange parking or a loading space
- Point out any areas we must not close
Getting a fixed quote
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

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.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
What we’re called out for in Portfield
Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears so backing is set before sealing.
What tends to prompt an enquiry:
- Arrises breaking up along floor joints
- Weathered movement joint sealant that no longer flexes
- Car park joints leaking onto vehicles below
- Debris jammed in movement joints
If you manage units on an estate such as St James Industrial Estate., which lies north of Portfield, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.
What your quote should include
- Their approach to joint depth and backing
- The terms of the workmanship guarantee
- Do they follow the manufacturer’s priming guidance?
- Which product they’ll use, and why it suits the joint
When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Cracking or settlement that calls for an engineer’s assessment
- Joints too narrow for the movement, which need redesigning by the engineer
- Proprietary pre-formed expansion joint systems
If in doubt, call the office on 01277 525 020 or email the details over and we will say what we think before you book.

Your questions answered
Can you work on a hospital site such as St Richard's Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Portfield too far out for you?
No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
What’s the difference between an expansion joint and a movement joint?
Movement joint is the broad term for any joint built in to let a structure move. On site, people tend to use them interchangeably.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
What causes movement joint sealant to fail?
Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. We diagnose which one it is before resealing since each needs a different fix.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
Can you work while the building is occupied?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
What sets the cost
There’s no standard rate for sealant work, because every site is different. What we look at:
- Joint width, depth and condition
- How accessible the joints are
- Phasing around occupants
- The site’s rules and procedures
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.
Before you send an enquiry
A good diagnosis starts with the right details. Let us know:
- Rough lengths or quantities, or drawings if you have them
- Anything awkward about access or site hours
- The asbestos register, for older buildings
- Your programme or deadline
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
