Commercial premises in Gravesend
Gravesend is about 29 miles from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Multi-site occupiers here often want one sealant contractor across all their buildings. Less than 3 miles from Gravesend there are two named estates and business parks. Each new occupier on a park like these tends to refit, from reception to staff kitchen; brand colours often come into it.
Trade counters and showrooms on estates such as Hadham Industrial Estate (1.6 miles south of Gravesend) need neat joints where customers see them. For premises near Bishops Stortford station, 4.2 miles to the south-east of Gravesend, footfall is part of the plan: work is phased so shops and offices keep trading.

About our commercial sealant contractors in Gravesend
How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead, and a backing rod limits the depth to give the sealant room to work. We work on movement joints in walls and floors, window and door perimeters and external facade joints, and the failures we’re asked to look at most are smeared sealant across finishes from a rushed job and gaps behind commercial kitchen worktops and sinks. Looking for mastic applicators who cover Gravesend? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
We price commercial jobs in Gravesend from photographs, drawings or a site visit, and the scope is set out in writing.
Business units in the countryside around places like Gravesend are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.
A 12-month guarantee applies to all our work. If an installation problem shows up, phone 01277 525 020 or send photos by email and we will arrange a return visit.

Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. If others near Gravesend need work, visits can be combined. You’ll have a fixed quote before work starts.
- Send details through our quote form, or ask for a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Where parts of the building must stay open, the work is phased.
- Every failed bead is removed rather than covered.
- A suitable product for each joint goes in at the right depth and is tooled.
- We check the work with you, and the 12-month guarantee starts.
What we need from you
- Make sure the joints can be reached
- Tell us your opening times and when work is allowed
- Confirm the product named in the specification
Getting a fixed quote
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or email drawings and photos.
Related advice
General trades versus a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Common questions from Gravesend clients
Does your area include sites such as Hadham Industrial Estate, near Gravesend?
Yes. Our area takes in Gravesend and its surroundings, with estates and business parks such as Hadham Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Is a smaller place like Gravesend outside your area?
No. Places such as Gravesend are covered as much as the big towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Is the old sealant taken out first?
Every failed bead is cut out completely. Laying new silicone on old gives it nothing to grip.
Are you CHAS accredited?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
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 work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
What site paperwork can you provide?
We confirm documents at quote stage: most clients ask for RAMS, our insurance certificate and CSCS details. Every applicator holds a CSCS card.
For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Do you need commercial sealant contractors in Gravesend?
Resealing over the top is a false economy we come across often. Fresh sealant won’t stick to the old bead underneath. Getting back to a clean joint then means removing every layer.
It’s worth sending us details if you spot any of the following:
- A top-up bead over failed sealant, now lifting
- Damp patches where an external joint has failed
- Frame sealant that has cracked, shrunk or pulled away
- Messy, uneven beads from earlier work that let the building down
A business with units at Hadham Industrial Estate and Oaks Industrial Park needn’t use two contractors for its sealant.

- What the guarantee covers, and for how long
How the job changes by surface
Washrooms and toilets
Mould that has grown into washroom sealant can’t usually be cleaned out. Replacement is the fix: strip, clean, dry and reseal, planned so the building keeps enough facilities in use.
Commercial kitchens and tea points
Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. Proper degreasing comes before any new sealant, and a hygienic or food-safe sealant is used where food contact is possible.

When something else is needed
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Water from a services leak rather than a joint
- Roof leaks that only look like a joint problem
- Walls or slabs moving more than any sealant can take
Not sure which it is? You can call 01277 525 020 or send photos by email and we will tell you honestly before you book.
