Expansion joint sealing in Hungerford, done properly
Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises and the bead bonds to the sides, never the back. We work on car park decks and ramps, brickwork movement joints and blockwork control joints, and what we’re called in for most is layers of sealant in a movement joint and spalled or broken joint edges in floors and decks.

In a smaller place such as Hungerford, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Concrete floors and yards in these buildings move and crack like any others.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

What we can’t put right
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Joints too narrow for the movement, which need redesigning by the engineer
- Crumbling edges that would give a new bead nothing sound to grip
- Damaged metal nosings or cover plates over a joint
If in doubt, phone 01277 525 020 or email us and we’ll say what we think.
What we seal
- Precast concrete panel joints
- Blockwork control joints
- Brickwork movement joints
- Cladding panel joints
- Podiums and floor movement joints
- Car park decks and ramps
Doing it in-house
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Expansion joint sealing in Hungerford: the local picture
The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in. Central London is about 62 miles from Hungerford. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.
At places like Station Yard Business Park (under half a mile east of Hungerford), joints are sealed a section at a time so operations carry on. Warehouse floors on estates like Hungerford Trading Estate, less than half a mile west of Hungerford, carry pallet trucks and forklifts over every saw-cut joint.

Leave it or put it right?
Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What else we do in Hungerford
Looking after the joints
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Brief car park operatives to protect joint lines during winter clearance
- Keep product details with the building records for the next reseal
- Put movement joints on the planned maintenance inspection round
- Reopen bays and walkways only after the stated cure time
Debris does more harm to joint sealant than most people realise. Stones pressed into the bead by wheels or feet can puncture it, especially on car park decks and warehouse floors. Regular sweeping keeps joint lines clear.
When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one, so the work can be planned rather than rushed. We will tell you which movement joints need doing now and which can wait.
What we are called out for in Hungerford
Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks.
Common reasons buildings call us in:
- Damp inside where a wall movement joint has failed
- Layers of sealant in a movement joint
- Movement joints with split or torn sealant
- Brittle, chalky sealant on external joints
In a school such as Hungerford Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
Questions to ask before you book
- What level of public liability insurance do they hold?
- Will failed sealant be removed rather than covered?
- Whether their applicators hold CSCS cards
- Which product they’ll use, and why it suits the joint
Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a site in Hungerford, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.
- 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.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Getting the site ready
- Share your working hours and any access restrictions
- Explain the parking and delivery arrangements
- Warn occupants and staff about the work
Getting a fixed quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
