About our expansion joint sealing in Great Amwell
We cover the full range of movement joints: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic. We work on precast concrete panel joints, cladding panel joints and car park decks and ramps, and the failures we are asked to look at most are debris jammed in movement joints and layers of sealant in a movement joint. A single leaking joint is often how a building in Great Amwell first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Halls, schools and small commercial buildings near places like Great Amwell have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Questions we are asked in Great Amwell
Does your area include sites such as Crane Mead Business Park, near Great Amwell?
Yes, sites like Crane Mead Business Park are within our area, along with the rest of Great Amwell. A few photographs and the unit address let us price the work.
Is Great Amwell too far out for you?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Can you work on car park ramps and decks?
Yes. Tell us how the car park is used and which areas must stay open, and we’ll plan the phasing around it.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
How much does the work cost?
It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.

- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability, 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.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.

Advice
Owners, agents and contractors
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Great Amwell can sit alongside others in a wider programme across Hertfordshire.
Looking after the joints
For the best life from the joints:
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Report split or peeling joint sealant early
- Plan racking layouts so feet don’t land on a joint
- Keep traffic off new joints until the cure time is up
Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. Should you spot a problem, you can ring 01277 525 020 or use the quote form and send a picture.
Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.
What happens if it’s left?
A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed, and we will say so before quoting. Older rural buildings around Great Amwell move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
Why us?
- Fixed quotes based on photographs, drawings or a visit
- Colour options checked against the specified product

When something else is needed
We check first that sealant really is the fix. It won’t put right:
- Movement on a scale no sealant is meant to absorb
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Joints too narrow for the movement, which need redesigning by the engineer
If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think.
Surfaces we seal
- Cladding panel joints
- Precast concrete panel joints
- Car park decks and ramps
- Podiums and floor movement joints
- Brickwork movement joints

Doing it in-house
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
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.
