Expansion joint sealing in Micklefield Green, done properly
Joint design counts for as much as the sealant itself. The joint has to be wide enough for the expected movement and the sealant’s movement capability, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1 and the bead bonds to the sides, never the back. We work on cladding panel joints, precast concrete panel joints and blockwork control joints, and the failures we are asked to look at most are water dripping through deck or ramp joints and movement joints with split or torn sealant. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Micklefield Green, preparation and product choice get the time they need.
Halls, schools and small commercial buildings near places like Micklefield Green have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Joints that move: notes for Micklefield Green
At about 21 miles from central London, Micklefield Green is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift. Rainfall across the South East, Micklefield Green included, is lower than in many parts of the UK. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints.
For a school such as Sarratt Church of England Primary School, playground and building joints can be done in the holidays. Sites like Leavesden Hospital, 3.9 miles to the north-east of Micklefield Green, carry ambulances, deliveries and visitors’ cars over their road and deck joints.
Micklefield Green is about 3 miles north of Rickmansworth, in Hertfordshire. Anywhere in WD3, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee.

How a job runs
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. For a building around Micklefield Green, 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 tell you if the design looks wrong for the movement.
- 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.
- Areas reopen once cured, and the work carries our 12-month guarantee.

FAQs: Micklefield Green
Is Micklefield Green too small for you to travel to?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Is a hospital such as Leavesden Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, let us know and we will send them with the quote.
Can you seal joints in cold or wet weather?
Sealing onto a damp surface leads to adhesion failure so we’d rather rearrange than seal in the rain. We agree a revised date with you.
Why do our movement joints keep failing?
Most often the movement is too much for the product or the joint width. That’s why we check width, depth and movement class before quoting so the same failure isn’t repeated.
When can you be on site?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Can you quote from photographs?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
When to bring in a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Looking after the joints
Regular inspection catches problems early. Specifically:
- Note which joints were done, when, and with what
- Keep traffic off new joints until the cure time is up
- Avoid parking heavy plant or pallets on joint lines
- Inspect movement joints alongside other routine building checks
In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines and flag chipped arrises before they spread.
External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors, well after the seal first opened. Resealing promptly prevents internal damage.
For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Changing the joint layout or spacing of a structure
- Crumbling edges that would give a new bead nothing sound to grip
If in doubt, ring 01277 525 020 or email drawings and photos and we will say what we think before you book.
