Our expansion joint sealing service in Windsor and Maidenhead
Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors on sites in Windsor and Maidenhead. We work on cladding panel joints, brickwork movement joints and podiums and floor movement joints, and the failures we are asked to look at most are leaks through car park deck joints onto the level below and damp inside where a wall movement joint has failed.
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.
- 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.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- 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.

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Floors, slabs and movement joints across Windsor and Maidenhead
Movement joints in brick, cladding panels and concrete appear on buildings all over Windsor and Maidenhead, from schools to offices and car parks. A failed joint lets in water and debris, and the edges spall soon after.
The South East has large numbers of business parks and industrial estates, especially around the motorway corridors, and we cover Windsor and Maidenhead along with the rest of the region.
Maidenhead: Phasing is what makes joint work possible on busy sites such as Cliveden View Shopping Centre (1.2 miles north of Maidenhead): one bay, aisle or car park row at a time. For buildings at a park such as Vanwall Business Park, which lies south-west of Maidenhead, brick and panel movement joints are easy to forget until one leaks.
What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Joints too narrow for the movement, which need redesigning by the engineer
- Broken or spalled joint edges, which need repairing before any sealant goes in
What affects the price in Windsor and Maidenhead
We price every job individually. The main factors are:
- The product specified
- Quantities, in metres or numbers
- Site requirements such as inductions and permits
- Phasing around occupants
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
What to include in your enquiry
However big the job, these details speed things up:
- The type of building and who uses it
- Any dates the work must fit around
- How the joints are reached, and at what height
- Photos of the joints, close up and from further back
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or email drawings and photos.
General trades versus a specialist
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.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Keeping the joints sound
Once the work is signed off, these steps help:
- Inspect exposed joints once the cold weather has passed
- Report split or peeling joint sealant early
- Raise snow-clearing blades over deck joints where possible
- Reopen bays and walkways only after the stated cure time
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file so future maintenance isn’t guesswork.
An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall, turning a sealant job into a repair job. Keeping the seal sound avoids all of that.
What happens if it’s left?
Spot repairs can be useful on a tight budget. But if the rest of the run is the same age and product, it’s typically not far behind. We can price a patch and a full reseal side by side.
Questions to ask before you book
- Are they CHAS accredited or on Constructionline?
- Their approach to joint depth and backing
- Will failed sealant be removed rather than covered?
- Which product they’ll use, and why it suits the joint
Your questions answered
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. 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.
Is Windsor and Maidenhead in your area?
Yes. Windsor and Maidenhead falls within our area, and the simplest way to start is to call 01277 525 020 or use the quote form.
What exactly is 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 and the way they’re sealed is similar.
Can you work on car park ramps and decks?
Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement.
What happens if it rains on the day?
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.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, which many sites require.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
