Expansion joint sealing for businesses in Capstone
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
When to call us in Capstone
Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens so backing is set before sealing.
If one of these sounds familiar, it’s time for a closer look:
- Layers of sealant in a movement joint
- Hardened, cracked sealant on exposed facades
- Joints where the bead has lost adhesion
- Rain penetration at brick or block movement joints
For buildings at a park such as Gillingham Business Park, 0.8 miles north-east of Capstone, brick and panel movement joints are easy to forget until one leaks.

Expansion joint sealing in Capstone, done properly
Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors. Site teams most often ask us about car park joints leaking onto vehicles below and hardened, cracked sealant on exposed facades, on precast concrete panel joints, podiums and floor movement joints and blockwork control joints. A specialist sealant contractor works differently from a general builder: on jobs in Capstone, preparation and product choice get the time they need.
For a site near Capstone, measurements and photographs up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Diagnose, treat, sign off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and we clear our waste as we work. Rural sites near Capstone may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- 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.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- 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
- Move anything stored against the joints
- Share the asbestos register for older buildings
- Explain the parking and delivery arrangements

Floors, slabs and movement joints in Capstone
Capstone is within about 3 miles of the coast. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so a failed joint lets more in and the edges break up sooner. Central London is about 30 miles from Capstone. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift.
University campuses such as University for the Creative Arts - Rochester (to the north-west of Capstone) have car parks, paved walkways and building elevations with movement joints. Across sites such as Hempstead Valley Shopping Centre (1.3 miles south-east of Capstone), floor and movement joints can be sealed in phases so units keep working.
Capstone is about 1 mile south-west of Gillingham, in Medway. Commercial clients in Capstone can call on us for movement joints. 54 places across Medway fall within our area, Capstone among them. Sites around London have their own page, about 30 miles away.
Business premises anywhere in ME7 are within our area for movement joints. We also cover Darland (1 mile north), Hale (1 mile north-west), Hempstead (1 mile south-east), Gillingham (1 mile north-east) and Chatham (1 mile west).

Near you in Capstone

Capstone’s nearest station is Gillingham (Kent) station, about 2 miles north.

What happens if it’s left?
On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use, compared with a full closure. We agree phasing with you before work starts. Around Capstone, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
Why us?
- Fully insured, including public liability cover
- One number for every site we cover
- Health and safety: CHAS accredited
- Workmanship guaranteed for 12 months

Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
What else we do in Capstone
After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Keep product details with the building records for the next reseal
- Put movement joints on the planned maintenance inspection round
- Plan racking layouts so feet don’t land on a joint
- Brief car park operatives to protect joint lines during winter clearance
In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints.
When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort. We will tell you which movement joints need doing now and which can wait.
Your questions answered
Can you work on a hospital site such as Medway Maritime Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you cover business parks and estates near Capstone, such as Gillingham Business Park?
Yes. Our area takes in Capstone and its surroundings, with estates and business parks such as Gillingham Business Park included. Send details of the unit and the work through our quote form for a quick quote.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
What’s the quickest route to a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Do the joint edges need to be sound before sealing?
Sound edges are essential. If they’re damaged, we’ll say so before any sealing.
What we can’t put right
Being straight saves everyone time. Fresh joints won’t solve:
- A joint that has to be widened or re-detailed before it can work
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly.
