Should maintenance staff do it?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
What the job involves on each 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, with a flexible sealant where movement is larger.
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement.
Honest limits
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Changing the joint layout or spacing of a structure
- Movement on a scale no sealant is meant to absorb
- Broken or spalled joint edges, which need repairing before any sealant goes in
Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we will tell you honestly.

How the quote is worked out
What shapes the price:
- Access and working height
- The size and state of each joint
- Induction, permit and paperwork requirements
- Whether the work must be split into stages
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.
Before you send an enquiry
Diagnosis starts before we arrive. Let us know:
- Any dates the work must fit around
- Photos of the joints, close up and from further back
- Asbestos survey details if the building is older
- Any specification or named product
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.
Questions we’re asked in Crowdhill
Will you take on work at estates like Vicarage Farm Business Park, close to Crowdhill?
Yes, sites like Vicarage Farm Business Park are within our area, along with the rest of Crowdhill. To start, just speak to us on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is Crowdhill off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you have public liability insurance?
Yes. We’re fully insured, and the certificate can go with your quote.
Can the building stay open while you work?
In the majority of cases, yes. Phased work can be planned so areas stay in use.
What timescale should we allow for resealing expansion joints?
Allow a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Timings are set out in the quote.
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, because fresh silicone will not bond with aged silicone.
Why has the sealant in our expansion joints split?
It depends on how the sealant has let go: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Broken edges are a third possibility.
From enquiry to sign-off
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. For work around Crowdhill, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take 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.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
What we need from you
- Tell staff and tenants when we’ll be in
- Flag any permit to work we’ll need
- Explain the parking and delivery arrangements

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Crowdhill is about 63 miles from central London. Warehousing clusters around the motorways that ring and radiate from London. Crowdhill is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints.
