Expansion joint sealing in Compton, done properly
Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side. A sealant suited to traffic and the expected movement goes in and the work can be phased so parts of the car park stay open. Most enquiries involve rain penetration at brick or block movement joints and torn sealant in brick or block movement joints, on brickwork movement joints, cladding panel joints and car park decks and ramps. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Compton it comes down to the same thing: the right product in a properly prepared joint.
Halls, schools and small commercial buildings near places like Compton have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to bring in a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Put movement joints on the planned maintenance inspection round
- Check joints after long freezing spells
- Keep traffic off new joints until the cure time is up
- Report split or peeling joint sealant early
Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check and long before edges start to break. If anything looks wrong, speak to us on 01277 525 020 or email the details over with photographs.
On a multi-storey car park, a failed joint usually shows up as a leak onto the deck underneath. That water often carries de-icing salts with it and it can affect the structure over time. Sealing the joint promptly stops it at source.
Diagnose, treat, sign off
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For work around Compton, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
What we need from you
- Let us know about inductions and permits
- Share the asbestos register for older buildings

Expansion joint sealing around Compton: points for this area
Rainfall across the South East, Compton 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 winter de-icing salt on car parks and ramps works into any open joint. Compton lies roughly 53 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.
Hospitals like Petersfield Community Hospital, 5.7 miles north of Compton, have multi-storey or surface car parks whose joints carry vehicles round the clock. For a school such as Compton and Up Marden CofE Primary School, playground and building joints can be done in the holidays.

Questions about Compton
Can you work on a hospital site such as Petersfield Community Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Is a smaller place like Compton outside your area?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Is colour matching possible?
That depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Do you guarantee expansion joint work?
Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.
Can you work on car park ramps and decks?
Yes. We use a sealant designed for wheel loads and the expected movement, and phased work can be planned so parts of the car park stay in use.
Why it’s worth doing now in Compton
Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach and we will tell you honestly. For buildings around smaller places like Compton, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Sending details for a quote
To price the job accurately, we need to understand the site. Useful things to include:
- Your programme or deadline
- A wide shot and a close-up of the area

- Rough lengths or quantities, or drawings if you have them
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
What the job involves on each surface
Cladding panel joints
Access to cladding joints is agreed before the price is fixed. Close-up photographs help us judge the joints, or we visit if they don’t show enough.
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.
