Construction mastic for commercial buildings in Hernhill
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up, so we plan elevations with the forecast and the programme in mind. Internal areas can normally carry on while the outside waits. If you are dealing with missed perimeter joints on a new elevation and oversized or tapered gaps around new frames, we can put it right. Facilities teams, main contractors and managing agents in Hernhill tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like Hernhill, building work typically 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 Kent. If an installation problem shows up, call the office on 01277 525 020 or send details through our quote form and we will arrange a return visit.

Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Release areas for mastic once other trades have finished in them
- Ask for joint and product checks before the package is urgent
- Keep scrapers and abrasive pads off new beads
- Keep product details for future maintenance
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement. If that happens, let us know.
Snag items left to the last week put handover at risk. A planned close-out through each area as it completes keeps the list short and keeps handover on track.
On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. Smaller jobs around Hernhill can be grouped with others nearby. A fixed quote is given before anything starts.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised straight away.

What we need from you
- Share the asbestos register for older buildings
- Move anything stored against the joints

Signs you need construction mastic in Hernhill
On construction sites, joints normally 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.
Site and facilities staff are often the first to spot these:
- Sanitary sealant damaged by following trades
- Old sealant on a refurbishment that needs stripping before new work
- Internal caulk splitting as the building dries out
- Frame perimeters left unsealed or poorly sealed
On a campus such as University of Kent, which lies east of Hernhill, new teaching buildings and residences are typically built and refurbished around the academic year.
Before you book anyone
- Whether primer will be used where the manufacturer specifies it
- Will CSCS-carded applicators be on site?
- The terms of the workmanship guarantee
- Is the sealant right for the movement and the substrate?

What else we do in Hernhill
Construction mastic around Hernhill: points for this area
Hernhill is within about 3 miles of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, and the sealant, primer and backing need choosing with that in mind. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.
For a contractor working at a hospital such as Whitstable and Tankerton Hospital, which lies north-east of Hernhill, perimeter and facade sealing is planned around patients and deliveries. School extensions, at buildings such as Hernhill Church of England Primary School, usually run to the summer holidays, mastic included.
Hernhill is about 3 miles east of Faversham, in Kent. We cover commercial sites throughout Hernhill, for single jobs and planned programmes alike. We work across 931 places in Kent, from busy centres to rural villages. London is covered too, around 47 miles from Hernhill.

FAQs: Hernhill
Does the sea air around Hernhill change the choice of sealant?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Will you take on work at estates like Waterham Business Park, close to Hernhill?
Yes. We cover Hernhill and the area around it, including industrial estates, business parks and retail parks such as Waterham Business Park. Send details of the unit and the work through our quote form for a quick quote.
Do you guarantee new-build sealant work?
Each package is signed off with a 12-month workmanship guarantee. The guarantee covers our work, not later damage by other trades.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
What site paperwork can you supply?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Should maintenance staff do it?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Glazing units that are cracked or misted
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Oversized gaps that need packing or adjustment by others
If you’re not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer.
