Floor joint sealing near Stevenage
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Sites in a big town such as Stevenage frequently have reception sign-in, inductions and permits to work. Tell us about inductions, permits and site hours so the plan fits.
- First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
- The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
- Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
- Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
- The chosen product is placed to its specified depth and trimmed level with the floor.
- We tell you when each zone can carry trucks again and move on to the next.
What we need from you
- Have the specification and drawings to hand
- Explain the parking and delivery arrangements
- Tell us your opening times and when work is allowed

Advice
Floor joint sealing in Stevenage
Sometimes the concrete either side of a joint has already spalled. Filling against a crumbled arris won’t hold for long, so if the edges need repair before any filling, we will say so and leave that decision with you. We work on construction joints, retail and showroom floors and loading bays, and the failures we’re asked to look at most are cracked and crumbling joint fill and filler that has parted from one face. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Stevenage, that means joint design, primers and backing rod as standard.
On busy estates around towns like Stevenage, joints are resealed in stages so units keep trading: one aisle, bay or level at a time, with areas handed back as each section cures.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

When it isn’t the sealant
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- A floor that rocks at the joints, which needs a structural fix
- Cracks across panels caused by settlement or overload
- Spalled arrises, which need an edge repair first
If in doubt, call the office on 01277 525 020 or send photos by email and we will say what we think.
What we seal
- Forklift and pallet-truck routes
- Loading bays
- Retail and showroom floors
- Joints along racking aisles
- Saw-cut induced joints
- Construction joints
Stevenage: questions and answers
Is Monkswood Retail Park, near Stevenage, within your area?
Yes. Our area takes in Stevenage and its surroundings, with estates and business parks such as Monkswood Retail Park included. To start, just speak to us on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Are the floor joints in an older unit in Stevenage worth resealing?
Generally yes, provided the arrises are still in reasonable shape. We will look at the joints, recommend a product for the traffic and movement, and say if any edges need repair before sealing.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Do you use semi-rigid filler or flexible sealant on floor joints?
It depends on the traffic and the movement. Forklift routes generally call for a semi-rigid filler that holds the arrises, while joints that move more take a flexible sealant.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do you repair broken joint edges?
A filler needs sound edges to grip. If the arrises have spalled, we will say they need repair before filling, so you can decide how to proceed.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Floors, slabs and movement joints in Stevenage
Stevenage sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in. As a twentieth-century planned town, Stevenage was designed rather than grown. With industry zoned from the outset, there’s a concentration of older warehouse floors whose joints take daily traffic, so a planned programme across a site can make sense.
For a school such as Saint Vincent de Paul Catholic Primary School, playground and building joints can be done in the holidays. Another example is Oaklands Retail Park (1.4 miles south-west of Stevenage), where floors and yards would be done in stages around the occupiers.

Why it’s worth doing now in Stevenage
Every jolt over a broken joint passes into the truck, the load and the driver. Wheels and bearings wear faster and loads can shift, adding costs nobody plans for. A filled joint takes most of that out. In a town the size of Stevenage, traffic, footfall and weather keep working on a failed joint. Acting early keeps it a sealant job.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

After the work
For the best life from the joints:
- Let us know what the floor is cleaned with
- Stop forks and pallets being dragged across joints
- Record damaged joints with a photo and a location
- Clear packed debris from open joints regularly
Keep traffic off fresh joints until the time we give you and it pays to stick to it. In a busy building, barriers keep early traffic away.
A broken joint on a main route is crossed by every truck on that route. Sorting it early looks after your equipment as well as the slab.
What affects the price in Stevenage
Your fixed quote is built from the real scope. It takes account of:
- The product specified
- Backing rod, priming and other preparation
- The total length or number of joints
- Working within restricted access windows
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- How the joints are reached, and at what height
- Where the site is, with the postcode
- Any specification or named product
- Whether an asbestos survey exists
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

What else we do in Stevenage
Common problems we fix in Stevenage
Loading bay joints are exposed to wind, wet tyres and bigger temperature swings on top of the heaviest turning movements. They are often the first on a site to break down.
These are often picked up first by site or facilities staff:
- Grimy joint lines spoiling a showroom floor
- Cracked and crumbling joint fill
- Joint fill separating from the concrete
- Sealant pulled out along a truck route
Places like Monkswood Retail Park (to the south-west of Stevenage) put trolleys over floor joints inside and cars over slab joints outside.
