Construction mastic for Gravesend sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Our process
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If others near Gravesend need work, visits can be combined. A fixed quote is given before anything starts.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Joints are prepared, backed and sealed to the specification.
- After snagging, the work is handed over under our 12-month guarantee.
Getting the site ready
- Tell us what induction or permit system the site runs
- Send asbestos survey details if the building is pre-2000
- Arrange parking or a loading space
Get a fixed quote
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Advice
About our construction mastic in Gravesend
The programme rarely stands still, so the mastic package has to flex with it. We agree a sequence at the start and adjust it as the site manager releases areas, so applicators arrive when areas are genuinely ready. That keeps the work right first time and saves rework. We work on window and door perimeters, internal decorators’ caulk and sanitary and kitchen joints, and the failures we are asked to look at most are new external sealant already peeling away and inconsistent sealant finishes from plot to plot. One point of contact handles commercial sealant work in Gravesend from the first photos to the final walk-round, for single jobs and planned programmes alike.
Around smaller places like Gravesend, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
A 12-month guarantee applies to all our work in Hertfordshire. Should something we installed fail, ring 01277 525 020 or email drawings and photos and we’ll come back to it.

Honest limits
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Joint design decisions that belong to the architect or engineer
- Approving fire stopping as compliant
- Faulty frames rather than failed sealant
If in doubt, speak to us on 01277 525 020 or email drawings and photos and we will say what we think before you book.
Surfaces we seal

After the work
For the best life from the joints:
- Release areas for mastic once other trades have finished in them
- Don’t force external sealing on a damp or frosty day
- Stick to the specified sealant rather than a generic substitute
- Ask for joint and product checks before the package is urgent
The package carries our 12-month guarantee for workmanship. Damage by others isn’t a workmanship fault which is why protection after sealing matters.
External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work, so we plan external work with that in mind.
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.
Would you work within a site like Herts and Essex Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Does the weather affect the work?
It can, for external work. 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.
Do you do internal caulk as well as external mastic?
Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens in one fixed quote.
How much does the work cost?
There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.
Commercial clients in Gravesend
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Common problems we fix in Gravesend
Value-engineered products sometimes end up in the wrong joints. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We stick to the specified product, or put any alternative to you first.
Common reasons buildings call us in:
- Old sealant on a refurbishment that needs stripping before new work
- Missed perimeter joints on a new elevation
- A mastic package split between trades with no clear owner
- External joints sealed in damp or cold conditions that are now failing
Extensions at sites like Herts and Essex Hospital (to the south-east of Gravesend) typically sit beside working departments, and the mastic follows strict access rules.
Questions to ask before you book
- Their public liability cover
- The terms of the workmanship guarantee
- Health and safety accreditation such as CHAS
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
New build and refits around Gravesend
Gravesend is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. Gravesend is about 29 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.
For contractors refurbishing units at places like Hadham Industrial Estate, 1.6 miles south of Gravesend, the mastic covers cladding panels, roller-door and window perimeters. Projects at schools like Albury Church of England Voluntary Aided Primary School work to term dates, so mastic is programmed tightly.

How the job changes by surface
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area and damaged joints are redone rather than patched.
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.
