Floors, slabs and movement joints in St Ibbs
At about 30 miles from central London, St Ibbs is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors. St Ibbs is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.
In a school such as St Ippolyts Church of England Aided Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
St Ibbs is about 2 miles south of Hitchin, in Hertfordshire. St Ibbs sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Hertfordshire, 371 places are covered, St Ibbs among them. London is covered too, some 30 miles away.
Anyone looking for expansion joint sealing in SG4 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. If your building is just outside St Ibbs, we cover Sperberry Hill (1 mile north-east), Little Almshoe (1 mile south), St Ippolyts (1 mile north-east), Gosmore (1 mile north-west) and Titmore Green (1 mile east).

Expansion joint sealing for commercial buildings in St Ibbs
Width, depth and product all have to work together. 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 and the bead bonds to the sides, never the back. The enquiries we see most involve water getting into the wall through a failed joint and movement joints with split or torn sealant, across cladding panel joints, precast concrete panel joints and brickwork movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in St Ibbs is the same: the right product in a properly prepared joint.
Smaller community and commercial buildings around St Ibbs have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Your questions answered
Is St Ibbs too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Can you work on a hospital site such as Pinehill Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
What do you charge?
That depends on the job: quantities, access, the product and any phasing. Call for a quote and we will price it properly.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
When to call us in St Ibbs
When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes, and it’s common on joints sealed in a hurry.
Any of the following is a good reason to get the joints checked over:
- Leaks through car park deck joints onto the level below
- Sealant peeling off one face of the joint
- Rain penetration at brick or block movement joints
- Previous reseals laid over old sealant
A healthcare site such as Pinehill Hospital (1.7 miles north of St Ibbs) depends on car parks, ramps and service yards whose joints take traffic all day.
What your quote should include
- What level of public liability insurance do they hold?
- How they’ll work around occupants
- Will failed sealant be removed rather than covered?
- Their pre-qualification and accreditations
Owners, agents and contractors
Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
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.
Quoting for work in St Ibbs
A fixed quote reflects the actual work. It allows for:
- Phasing around occupants
- Location, for remote and island sites
- How much existing material needs removing
- Which sealant the job calls for
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Before you send an enquiry
A good diagnosis starts with the right details. Tell us:
- Whether an asbestos survey exists
- Any dates the work must fit around
- Photos of the joints, close up and from further back
- The site address and postcode
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Smaller jobs around St Ibbs can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- You get a fixed quote with the product and its movement capability stated.
- We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Each joint is inspected and handed over with our 12-month guarantee.
Getting the site ready
- Share your working hours and any access restrictions
- Let us know about inductions and permits
- Let building users know which areas are affected
Getting a fixed quote
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or email us if you’d rather talk the job through.

When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Changing the joint layout or spacing of a structure
- Leaks coming from the membrane rather than the joint seal
- Crumbling edges that would give a new bead nothing sound to grip
If in doubt, give us a call on 01277 525 020 or email the details over and we’ll say what we think before you book.

What the job involves on each surface
Cladding panel joints
Access to cladding joints is agreed before the price is fixed. Close-up photographs help us judge the joints, or we visit if they don’t show enough.
Joints between different materials
Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces, with primer where specified.
