How we handle expansion joint sealing in Hempstead
We have been sealing expansion and movement joints for over 20 years for contractors, facilities managers and owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. If you’re dealing with water getting into the wall through a failed joint and spalled or broken joint edges in floors and decks, we can put it right, on brickwork movement joints, precast concrete panel joints and car park decks and ramps alike. Most enquiries from Hempstead start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Work in a smaller place like Hempstead is normally one building at a time, so we gather photographs and measurements first. Getting widths, depths and traffic details up front means one visit, not two.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Maintenance after handover
After handover, a little attention goes a long way:
- Look over external and deck joints after a hard winter
- Clear dirt from joint lines during routine cleaning
- Treat a small split as a warning, not a cosmetic issue
- Include every elevation and deck joint in periodic inspections
Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in. If anything looks wrong, call the office on 01277 525 020 or email the details over with photographs.
External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint. Catching it early keeps the water outside.

Joints that move: notes for Hempstead
Hempstead lies within about 3 miles of the sea. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, which is why split joints are worth sealing before the edges deteriorate. At about 30 miles from central London, Hempstead is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day.
Another example is Gillingham Business Park, 1.1 miles to the north of Hempstead, where floors and yards would be done in stages around the occupiers. Retail sites such as Hempstead Valley Shopping Centre (0.6 miles south of Hempstead) have car park, service yard and shop floor joints under constant traffic.
Hempstead is about 2 miles south of Gillingham, in Medway. Anywhere in ME7, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Hempstead is one of 54 places we cover in Medway. For work in that direction, see our London page (30 miles or so).
If you need expansion joint sealing in ME7 and ME8, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Several jobs near Hempstead can be grouped on one trip. Mention the building’s opening times and we’ll work within them.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- 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.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
What we need from you
- Explain the parking and delivery arrangements
- Make sure the joints can be reached
- Warn occupants and staff about the work

What we are called out for in Hempstead
Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it, so we tell you if the edges need repairing first.
It’s worth sending us details if you spot any of the following:
- Movement joints with split or torn sealant
- Layers of sealant in a movement joint
- Water dripping through deck or ramp joints
- Expansion joints filled with dirt and stones
Schools like Hempstead Infant School often have long brick elevations with movement joints that age quietly.
Questions to ask before you book
- What the guarantee covers, and for how long
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Their plan for phasing and protecting the area
- Which product they’ll use, and why it suits the joint
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

Your fixed quote is built from the real scope. It allows for:
- Whether the work must be split into stages

What site paperwork can you supply?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Honest limits
Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Leaks coming from the membrane rather than the joint seal
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.
