What happens if it’s left?
Patching the worst lengths of a joint can make sense short term. The remaining sealant is often close to failing too and repeated access costs add up. Where it helps, we quote both options. Converted and older buildings near places like Little London tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Expansion joint sealing in Little London, done properly
Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant, 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. Most enquiries involve rain penetration at brick or block movement joints and leaks through car park deck joints onto the level below, across podiums and floor movement joints, blockwork control joints and cladding panel joints. Searching for sealant specialists in Little London? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Halls, schools and small commercial buildings near places like Little London have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Cracking or settlement that calls for an engineer’s assessment
- Leaks coming from the membrane rather than the joint seal
- Concrete or masonry repairs along the arrises
If you’re not sure, just ring 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

What affects the price in Little London
We price every job individually. The main factors are:
- Removal of failed or old sealant
- The size and state of each joint
- Travel to remote or island sites
- Which sealant the job calls for
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
Before you send an enquiry
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- Rough lengths or quantities, or drawings if you have them
- How the joints are reached, and at what height
- Any specification or named product
- When you need the work done
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to speak to us on 01277 525 020 or email a schedule or drawings with what you know.
What we are called out for in Little London
Repeated failure often traces back to the wrong product. A stiff or general-purpose sealant across a joint with large movement won’t cope. BS EN ISO 11600 classifies building sealants by movement capability.
Common reasons buildings call us in:
- Previous reseals laid over old sealant
- Weathered movement joint sealant that no longer flexes
- Sealant pulling off the joint face
- Debris jammed in movement joints
Schools like St Peter's CofE Primary School often have long brick elevations with movement joints that age quietly.

- Will CSCS-carded applicators be on site?
- Their pre-qualification and accreditations
- Which product they’ll use, and why it suits the joint
Questions we are asked in Little London
Would you work within a site like Princess Royal Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will you take on work at estates like Horsted Keynes Business Park, close to Little London?
Yes. We cover Little London and the area around it, including industrial estates, business parks and retail parks such as Horsted Keynes Business Park. Send details of the unit and the work through our quote form for a quick quote.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Why do our movement joints keep failing?
Usually the joint is moving more than the sealant can take. That’s why we check width, depth and movement class before quoting.
What guarantee do you give on joint sealing?
Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.
What sealant do you use in movement joints?
We choose a sealant with a movement capability that suits the joint, classified under BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.

Diagnose, treat, sign off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. Rural sites near Little London may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We look at the joints, their width and how they’ve failed.
- Next, we fix a price and confirm the sealant we propose for the movement.
- We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Finished joints are checked and backed by our 12-month guarantee.

Looking after the joints
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Look over external and deck joints after a hard winter
- Note which joints were done, when, and with what
- Keep racking legs and heavy point loads off floor joints
- Keep scrapers and ploughs from dragging across joint sealant
Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth. Keeping the area coned off until then avoids tyre marks and damage.
Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.
