Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How the quote is worked out
Before we quote, we look at:
- Site requirements such as inductions and permits
- How much there is to seal
- Whether the work must be split into stages
- The size and state of each joint
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Sending details for a quote
Good information means a firmer quote. When you get in touch, include:
- A wide shot and a close-up of the area
- When you need the work done
- Whether the building will be occupied during the work
- Access details, including height
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.
Commercial sealant contractors for commercial buildings in Capstone
How long a joint lasts is decided before any sealant leaves the gun. Silicone has no grip on cured silicone, so the failed bead is cut out completely, then both faces are cleaned back to sound, dry material with no dust or grease on them. Primer is used wherever the manufacturer calls for it on that surface. The enquiries we see most involve expansion joints with the sealant torn out and hardened, chalky sealant on south-facing or exposed elevations, across washrooms and tea points, kitchen worktops and splashbacks and external facade joints. Whoever orders the work in Capstone, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In an occupied building in Capstone, the job is planned so areas stay in use: washrooms in turn, floors in sections and entrances kept open.
Work in smaller places such as Capstone tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Why act early in Capstone
A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. Often the fitting is sound and the joint is the only thing letting it down. A careful reseal is a far smaller undertaking than replacement, though we will tell you honestly if the element itself is the problem. One visit to deal with every failing joint makes more sense than several trips to a place like Capstone, rather than one at a time. Photos of every joint help us quote for the whole job.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Make sure contractors see the asbestos survey before cutting out old mastic
- Keep a record of which joints were resealed and when
- Report cracked or peeling sealant early
- Add sealant to the planned maintenance inspection list
We stand behind the workmanship with a 12-month guarantee. Keep the handover details with your O&M or maintenance records.
An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Cleanability is something environmental health officers pay attention to, so sound, smooth joints matter.
Your questions answered
Is Capstone off your patch?
No. Places such as Capstone are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Does your area include sites such as Gillingham Business Park, near Capstone?
Yes, sites like Gillingham Business Park are within our area, along with the rest of Capstone. To start, just ring 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
How do we get a quote?
Start with whatever information is to hand. Questions or a site visit follow where needed.
Can you take on work for an FM or managing agent?
Yes. You can send details through our quote form, and we will confirm any paperwork you need with the quote.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Working on commercial sites near Capstone
With the shore within about 3 miles, Capstone counts as a coastal location. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. We choose a product rated for the exposure, then confirm the colours available for it. Central London is about 30 miles from Capstone. The commuter belt holds a great many offices, retail parks and business parks. If you have premises across the region, one contractor can cover them all.
A business with units at Gillingham Business Park and Hempstead Valley Shopping Centre needn’t use two contractors for its sealant. Shops and cafés around stations like Gillingham (Kent) station, 2 miles to the north of Capstone, trade from early, so work is timed around them. Offices at parks like Gillingham Business Park (0.8 miles north-east of Capstone) have receptions, kitchens and glazed partitions where a tidy joint matters.
Capstone is about 1 mile south-west of Gillingham, in Medway. Across the ME7 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Capstone is one of 54 places we cover in Medway for sealant joints. For work in that direction, see our London page, about 30 miles away.
If you need commercial sealant contractors in ME7, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed.

Different surfaces, different methods
Fire-rated seals where specified
Fire-rated sealant is only one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services and gaps, so we’ll flag it if the detail needs a different product.
Movement joints in walls and floors
Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. When the seal fails, debris gets in and the joint stops working. The joints are resealed using a sealant matched to the movement and any traffic.
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If others near Capstone need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- First, details reach us through the quote form or a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Work is phased around your occupiers where areas need to stay in use.
- Old sealant is cut out completely, never sealed over.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
Before we start on site
- Let building users know which areas are affected
- Point out parking and an unloading spot
- Send asbestos survey details if the building is pre-2000
