Warehouse floors and decks around Hythe
Hythe sits close to the coast, within about 1 mile. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, and edges left open tend to break up faster. Rainfall across the South East, Hythe included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in.
Warehouse floors on estates like Hardley Industrial Estate, 1.4 miles south of Hythe, carry pallet trucks and forklifts over every saw-cut joint. Sites like Hythe Hospital, under half a mile to the south-west of Hythe, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

How we handle expansion joint sealing in Hythe
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 seal across each one keeps out water and grit. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors. Most enquiries involve joints packed with grit and debris and torn sealant in brick or block movement joints, on blockwork control joints, precast concrete panel joints and cladding panel joints. One point of contact handles commercial sealant work in Hythe from the first photographs to the final walk-round, for single jobs and planned programmes alike.
In Hythe, as in most towns, brickwork and panel movement joints on public and commercial buildings age quietly. Once the sealant hardens or splits, water gets into the wall and the joint no longer works.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When to bring in a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
Our process
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. Most work in Hythe is one building at a time: a school, a unit, an office or a block. Your photos, drawings or a site visit come first, followed by a fixed quote.
- We look at the joints, their width and how they’ve failed.
- A fixed quote follows, naming the sealant and its movement class.
- The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Finished joints are checked and backed by our 12-month guarantee.
Before we start on site
- Share your working hours and any access restrictions
- Send asbestos survey details if the building is pre-2000
- Let building users know which areas are affected

Common questions from Hythe clients
Will you take on work at estates like Hardley Industrial Estate, close to Hythe?
Yes, sites like Hardley Industrial Estate are within our area, along with the rest of Hythe. A few photographs and the unit address let us price the work.
Is hospital work, at somewhere like Hythe Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you handle several sites?
Yes. A group of buildings can go on one quote, with one point of contact.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call the office on 01277 525 020 or email us. Include photos or drawings if you have them.
How long will the joint resealing take?
Allow anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. We confirm the timescale with the quote.
Do you use silicone or polyurethane in movement joints?
It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks usually need a polyurethane, and the specification has the final say.

Different surfaces, different methods
Brickwork and blockwork joints
Masonry faces are often porous, dusty or crumbly. Faces are prepared and primed wherever the sealant maker calls for it.
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it, so the new seal holds.
When to call us in Hythe
Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again, so we check width and movement before quoting.
Most enquiries start with something like this:
- Spalled or broken joint edges in floors and decks
- Hardened, cracked sealant on exposed facades
- New sealant over old, now failing
- Torn sealant in brick or block movement joints
In a school such as Waterside Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
What to look for in a quote
- Are they CHAS accredited or on Constructionline?
- How long is the guarantee, and what does it include?
- How they handle RAMS and site documents
- How joint depth will be controlled
After the work
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Inspect movement joints alongside other routine building checks
- Keep stones and debris out of open joint lines
- Act on the first tear or lifting edge rather than waiting
- Plan racking layouts so feet don’t land on a joint
Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.
