Expansion joint sealing in Barwell
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Should maintenance staff do it?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
About our expansion joint sealing in Barwell
Internal floor joints take trolleys, pallet trucks and forklifts. Without a sound filler, joint edges chip and spall under load, so the right filler or sealant for the traffic and movement matters. We’ll tell you if the edges need repairing before sealing, and phased work keeps areas in use. We work on blockwork control joints, brickwork movement joints and precast concrete panel joints, and the usual reasons a site gets in touch are spalled or broken joint edges in floors and decks and brittle, chalky sealant on external joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Barwell it comes down to the same thing: the right product in a properly prepared joint.
Around Barwell, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. A failed joint lets water and debris in, and the edges soon spall, so it pays to act early.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

On site: what to expect
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. All of Greater London is in the ULEZ, and kerbside space in Barwell can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Getting the site ready
- Let us know about inductions and permits
- Let building users know which areas are affected

Related advice
Leave it or put it right?
A like-for-like reseal of a joint that keeps splitting rarely lasts. If the joint is too narrow or the product wrong for the movement, it needs a different approach. In Barwell, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Your questions answered
Would you work within a site like West Park Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
Why do our movement joints keep failing?
Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing.
What timescale should we allow for resealing expansion joints?
That depends on joint lengths, widths, access and how much old sealant or filler needs removing. As a guide, it typically takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints.
Quoting for work in Barwell
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Working within restricted access windows
- Which sealant the job calls for
- Quantities, in metres or numbers
- Access and working height
There’s no price list, because the scope varies so much from one building to the next. Call for a quote.
What to include in your enquiry
However big the job, these details speed things up:
- Photos of the joints, close up and from further back
- Approximate linear metres or a joint schedule
- Whether an asbestos survey exists

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to speak to us on 01277 525 020 or email drawings and photos.

When to call us in Barwell
Some joints were never sealed with the right product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.
It’s worth sending us details if you spot any of the following:
- Previous reseals laid over old sealant
- Arrises breaking up along floor joints
- Movement joints with split or torn sealant
- Expansion joints filled with dirt and stones
Phasing is what makes joint work possible on busy sites such as Silverglade Business Park (1.1 miles south of Barwell): one bay, aisle or car park row at a time.

Looking after the joints
Your facilities or cleaning team can help the joints last. Share these points with them:
- Include every elevation and deck joint in periodic inspections
- Reopen bays and walkways only after the stated cure time
- Look over external and deck joints after a hard winter
- Brief car park operatives to protect joint lines during winter clearance
Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check, when they’re still cheap to deal with. If anything looks wrong, call 01277 525 020 or send photos by email with photos.
Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors, well after the seal first opened. Resealing promptly prevents internal damage.
