Expansion joint sealing in St Stephens
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, the width-to-depth ratio is often around 2:1, as the manufacturer advises. Most enquiries involve sealant peeling off one face of the joint and torn sealant in brick or block movement joints, on car park decks and ramps, blockwork control joints and precast concrete panel joints. Most enquiries from St Stephens start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Small units near places like St Stephens are often converted farm buildings with new concrete floors. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.
We stand by our work with a 12-month guarantee. That covers our preparation and application.

How a job runs
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. For a job in St Stephens, the main thing is a clear picture of the work, so send photographs of each area. You will then get a fixed price for the work.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability.
- 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.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- Move anything stored against the joints
- Flag any permit to work we’ll need
- Explain the parking and delivery arrangements
Getting a fixed quote

Common questions from St Stephens clients
Can you take on a job at a hospital such as St Albans City Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is St Stephens too small for you to travel to?
No. Places such as St Stephens are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Can you seal car park deck joints?
Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement with bays phased so the car park keeps operating.
How do we ask for a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or email a schedule or drawings. Include photographs or drawings if you have them.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Honest limits
Sealant solves a lot, but not everything, 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
- Waterproofing layers buried beneath the sealant
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
If in doubt, give us a call on 01277 525 020 or email us and we will say what we think.
Where we work in St Stephens

Why deal with it now?
Combining joint work with other maintenance reduces set-up costs. But joints already letting water in shouldn’t wait for a programme. Urgent joints now, the rest later, is often the sensible plan. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
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.

- One phone line for London, the South East and Scotland
- Over 20 years of commercial sealing

Warehouse floors and decks around St Stephens
The 3 miles around St Stephens take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Central London is about 20 miles from St Stephens. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift.
For a centre such as Village Arcade St Albans, 0.7 miles to the north-east of St Stephens, the service yard and car park joints normally need attention first. Phasing is what makes joint work possible on busy sites such as North Orbital Commercial Park (1.4 miles south-east of St Stephens): one bay, aisle or car park row at a time. Campuses like University of Hertfordshire (to the east of St Stephens) mix old and new buildings, with movement joints wherever they meet.
St Stephens is about 1 mile south-west of St Albans, in Hertfordshire. We send applicators to St Stephens for movement joints, handled exactly as we handle every other area. We work across 371 places in Hertfordshire. Our London page has more on work in that area (20 miles or so).

Other services in St Stephens
Site staff or a sealant specialist?
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. 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 our CSCS-carded applicators are used to working under those rules.
Quoting for work in St Stephens
Each job is priced on its own details. The things that drive the figure:
- The site’s rules and procedures
- Removal of failed or old sealant

What we need to price the job
However big the job, these details speed things up:
- How the joints are reached, and at what height

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call 01277 525 020 or email us.
Maintenance after handover
To get the most from the new sealant:
- Brief car park operatives to protect joint lines during winter clearance
- Keep racking legs and heavy point loads off floor joints
- Include every elevation and deck joint in periodic inspections
- Keep traffic off new joints until the cure time is up
Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. Regular sweeping keeps joint lines clear.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort so you can prioritise and budget. We can suggest an order, worst joints first.
