Expansion joint sealing in Falmer
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Honest limits
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Concrete or masonry repairs along the arrises
- Joints too narrow for the movement, which need redesigning by the engineer
- Damaged metal nosings or cover plates over a joint
If in doubt, phone 01277 525 020 or send details through our quote form and we’ll say what we think.

A single leaking joint is often how a building in Falmer first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Traffic, movement and joints around Falmer
Less than 3 miles from Falmer there are at least three named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Rainfall across the South East, Falmer included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in.
Campuses like University of Sussex (less than half a mile north-west of Falmer) mix old and new buildings, with movement joints wherever they meet. A healthcare site such as Nuffield Health Brighton Hospital (2 miles south of Falmer) depends on car parks, ramps and service yards whose joints take traffic all day. Phasing is what makes joint work possible on busy sites such as Westergate Business Centre (1.5 miles south-west of Falmer): one bay, aisle or car park row at a time.

Quoting for work in Falmer
These are the things that shape the price:
- The size and state of each joint
- The product specified
- How much there is to seal
- Induction, permit and paperwork requirements
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Sending details for a quote
The more we know, the firmer the quote. Helpful details to send:
- The postcode of the building
- Any specification or named product
- Whether an asbestos survey exists
- What the building is and how it’s used
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or send details through our quote form.
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Keep product details with the building records for the next reseal
- Inspect exposed joints once the cold weather has passed
- Act on the first tear or lifting edge rather than waiting
- Include every elevation and deck joint in periodic inspections
Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file, so the next reseal starts with the facts.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort, so the work can be planned rather than rushed. We will tell you which movement joints need doing now and which can wait.
On site: what to expect
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. Smaller jobs around Falmer can be grouped with others nearby. You’ll have a fixed quote before work starts.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.

Advice
Your questions answered
Is hospital work, at somewhere like Nuffield Health Brighton Hospital, something you do?
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.
Will you take on work at estates like Fairway Industrial Estate, close to Falmer?
Yes. Estates, retail parks and business parks around Falmer, Fairway Industrial Estate among them, are all within reach. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Do you guarantee expansion joint work?
Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, let us know and we will send them with the quote.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.

Leave it or put it right?
A torn seal left alone usually gets worse. Grit and water fill the gap and the material either side breaks up. Acting at the first split keeps the cost down. One visit to deal with every failing joint makes more sense than several trips to a place like Falmer, rather than one at a time. Send photographs of each area and we will quote for the lot.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Surface by surface
Podium joints
Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen in a colour confirmed for that product.
