What sealant work can’t fix
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Proprietary pre-formed expansion joint systems
- Waterproofing layers buried beneath the sealant
- Cracking or settlement that calls for an engineer’s assessment
If in doubt, call 01277 525 020 or send details through our quote form and we will say what we think before you book.

How we handle expansion joint sealing in Layston
Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap, so failed seals soon lead to leaks onto the level below and broken edges. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. We work on brickwork movement joints, blockwork control joints and podiums and floor movement joints, and the failures we are asked to look at most are torn sealant in brick or block movement joints and water getting into the wall through a failed joint. A single leaking joint is often how a building in Layston first comes to us: we look at the rest while we are there and tell you what we find.
Around smaller places such as Layston, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Layston: questions and answers
Does a site in Layston have to shut while its joints are sealed?
In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.
Is Layston too far out for you?
Not at all: smaller places are covered as well as 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.
What sealant do you use in movement joints?
We choose a sealant with a movement capability that suits the joint. Where two different materials meet, a hybrid sealant can be the better choice.
What if the joint edges are damaged?
Spalled edges need repairing before a new seal will last, and we’ll point out where that’s the case. Sealing over them leads to early failure.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Are you insured?
Yes. We are fully insured, including public liability cover.
From enquiry to sign-off
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Smaller jobs around Layston can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- We look at the joints, their width and how they’ve failed.
- A fixed quote follows, naming the sealant and its movement class.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
What we need from you
- Send any specification or drawings in advance
- Tell us your opening times and when work is allowed
- Point out parking and an unloading spot

Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
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.
What happens if it’s left?
Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall, so a reseal turns into an edge repair as well. Resealing early keeps the work to sealant. Converted and older buildings near places like Layston tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Do you need expansion joint sealing in Layston?
Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks, so it can’t follow the movement any more.
It’s worth sending us details if you spot any of the following:
- Damp inside where a wall movement joint has failed
- Water dripping through deck or ramp joints
- Chipped joint edges on forklift routes
- Brittle, chalky sealant on external joints
Across sites such as Watermill Industrial Estate, which lies south-west of Layston, floor and movement joints can be sealed in phases so units keep working.
Before you book anyone
- Is the sealant right for the movement and the substrate?
- Are they CHAS accredited or on Constructionline?
- What level of public liability insurance do they hold?
- Do they follow the manufacturer’s priming guidance?
