Construction mastic for Northfleet Green sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Your questions answered
Would you work within a site like Gravesham Community Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Can you work at a site such as Imperial Business Park, by Northfleet Green?
Yes. Our area takes in Northfleet Green and its surroundings, with estates and business parks such as Imperial Business Park included. A few photographs and the unit address let us price the work.
What hours do you work?
Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
Can you fit around our programme?
The programme sets the job. Tell us the sequence and we’ll plan applicators around it.
Construction mastic for commercial buildings in Northfleet Green
The specification and the programme set the job, not to habit. If a product is named, that’s what goes in. Backing, primer and depth follow what the sealant maker sets out, so the joints perform as the designer intended. If you’re dealing with mastic snags holding up handover and sanitary sealant damaged by following trades, we can help. One point of contact handles commercial sealant work in Northfleet Green from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Construction in and around smaller places such as Northfleet Green is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

When to call us in Northfleet Green
On construction sites, joints typically fail early because of when they were sealed, not what was used. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, and the joint has to be redone.
Things that typically lead to an enquiry:
- Missed perimeter joints on a new elevation
- Mastic snags holding up handover
- Inconsistent sealant finishes from plot to plot
- Sealant knocked or painted over by other trades
Hotels like Tollgate Hotel, 1 mile east of Northfleet Green, rarely close for long, so refurbishment mastic is phased floor by floor.
What your quote should include
- Will CSCS-carded applicators be on site?
- How joint depth will be controlled
- Their public liability cover
- How they handle RAMS and site documents

Advice
When to bring in a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
After the work
After handover, a little attention goes a long way:
- Share drawings and the specification as soon as possible
- Don’t force external sealing on a damp or frosty day
- Protect sealed areas from following trades
- Keep scrapers and abrasive pads off new beads
Brief the sparkle clean so they don’t scrape the new joints. Blades and abrasive pads are the commonest cause of damage at the final clean, so stick to soft cloths and gentle cleaners near sealant.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Waiting for a dry joint and the right temperature is better than redoing work.
Why deal with it now?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. Sound frames often need only a new perimeter seal and that’s a far smaller job. We will say so if a frame itself is the problem. One visit to deal with every failing joint makes more sense than several trips to a place like Northfleet Green, rather than one at a time. Send photos of each area and we’ll quote for the lot.
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

Building and refurbishing in Northfleet Green
Several hotels sit less than 2 miles from Northfleet Green. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. Central London is about 19 miles from Northfleet Green. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.
Projects at colleges like North West Kent College, 2.8 miles north-east of Northfleet Green, tend to run to term dates, so the mastic is planned tightly. Hospital estates such as Gravesham Community Hospital (to the north-east of Northfleet Green) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
