About our expansion joint sealing in Long Marston
Brickwork and blockwork walls have vertical movement joints at intervals, and they’re easy to miss until the sealant fails. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied with primer where the maker calls for it. The enquiries we see most involve chipped joint edges on forklift routes and brittle, chalky sealant on external joints, across brickwork movement joints, car park decks and ramps and blockwork control joints. A specialist sealant contractor works differently from a general builder: on jobs in Long Marston, preparation and product choice get the time they need.
Around smaller places such as Long Marston, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Work for main contractors and building owners
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Why act early in Long Marston
Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use without shutting the whole car park. Tell us what has to stay open and we’ll plan around it. Halls, stores and units around places like Long Marston may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
Why us?
- Old sealant cut out, never sealed over
- Our applicators hold CSCS cards
- Products installed to the manufacturer’s instructions
- CHAS accredited contractor
Traffic, movement and joints around Long Marston
At least three named trading, business or retail sites lie within about 3 miles of Long Marston. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Long Marston sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.
Large sites such as Tindal Centre (to the west of Long Marston) have car parks, service roads and long elevations with movement joints in brick and panels. Warehouse floors on estates like Old Airfield Industrial Estate, 1.1 miles to the east of Long Marston, carry pallet trucks and forklifts over every saw-cut joint.

On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Long Marston, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
Before we start on site
- Share the asbestos register for older buildings
- Tell us which areas need to stay in use
- Arrange parking or a loading space

Looking after the joints
For the best life from the joints:
- Keep product details with the building records for the next reseal
- Treat a small split as a warning, not a cosmetic issue
- Leave barriers in place until fresh joint sealant has cured
- Avoid parking heavy plant or pallets on joint lines
Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in 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 normally 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. Resealing early limits the damage.
Common problems we fix in Long Marston
When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons, and it’s common on joints sealed in a hurry.
It’s worth sending us details if you spot any of the following:
- Joints packed with grit and debris
- Layers of sealant in a movement joint
- Movement joints with split or torn sealant
- Arrises breaking up along floor joints
In a school such as Long Marston VA Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Long Marston: questions and answers
Can you take on a job at a hospital such as Tindal Centre?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you cover business parks and estates near Long Marston, such as Old Airfield Industrial Estate?
Yes. Estates, retail parks and business parks around Long Marston, Old Airfield Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Can you work on car park ramps and decks?
Yes. We use a sealant designed for wheel loads and the expected movement.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you use silicone or polyurethane in movement joints?
It depends on the movement, exposure and traffic. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints.
