Expansion joint sealing across Stock
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
From enquiry to sign-off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Stock need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- First, the joints are inspected for width, movement and the type of failure.
- 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, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Finished joints are checked and backed by our 12-month guarantee.
Getting the site ready
- For older buildings, check the asbestos register before work
- Arrange parking or a loading space
- Share your working hours and any access restrictions

Expansion joint sealing in Stock
Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement, phasing bays so the car park can stay in use. We work on precast concrete panel joints, brickwork movement joints and car park decks and ramps, and what we’re called in for most is hardened, cracked sealant on exposed facades and torn sealant in brick or block movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Stock it comes down to the same thing: the right product in a properly prepared joint.
Halls, schools and small commercial buildings near places like Stock have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Common problems we fix in Stock
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens.
It’s worth sending us details if you spot any of the following:
- Sealant peeling off one face of the joint
- Torn sealant in brick or block movement joints
- Water getting into the wall through a failed joint
- Expansion joints filled with dirt and stones
Sites like Mayflower Community Hospital (3.4 miles south-west of Stock) carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Should maintenance staff do it?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Slabs, ramps and loading bays in Stock
Stock lies roughly 26 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Rainfall across the South East, Stock included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.
For a school such as Stock Church of England Primary School, playground and building joints can be done in the holidays.

Different surfaces, different methods
Concrete and precast panel joints
Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.
Questions we are asked in Stock
Do you take on work at healthcare sites like Mayflower Community Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does a site in Stock have to shut while its joints are sealed?
In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Why has the sealant in our expansion joints split?
The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. We diagnose which one it is before resealing.
What will the job cost?
We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.
Can you work while the building is occupied?
In the majority of cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
Why act early in Stock
Leaving a failed movement joint rarely stays a small problem. 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 Stock, rather than one at a time. Send photos of each area and we’ll quote for the lot.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Record the sealant used and the date in the O&M file
- Report split or peeling joint sealant early
- Raise snow-clearing blades over deck joints where possible
- Put movement joints on the planned maintenance inspection round
Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check, when they’re still cheap to deal with. Should you spot a problem, you can speak to us on 01277 525 020 or send details through our quote form and send a picture.
External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint, well after the seal first opened. Catching it early keeps the water outside.
