Construction mastic near Chatham

Surface by surface
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. A single team keeps the standard consistent, plot by plot or floor by floor.
Kitchens and utility areas
Kitchen joints are sealed after fitting and before final clean. A kitchen-suitable sealant is used and hygienic or food-safe grades wherever food contact is possible.
Construction mastic in Chatham
The specification and the programme set the job rather than whatever product is to hand. If a product is named, that’s what goes in. Backing, primer and depth follow what the sealant maker sets out so the detail on the drawing is what ends up on site. If you have bath and shower joints scraped during the final clean and a mastic package split between trades with no clear owner, we can put it right, whatever the surface. Searching for sealant specialists in Chatham? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Business parks and retail centres around large towns like Chatham are refurbished and reclad as tenants change. All of it ends in perimeter and panel joints that need correct sizing, backing and sealant.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.
When to bring in a specialist
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.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
For managing agents and facilities managers
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Sites and facades in and around Chatham
Chatham is about 29 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.
Extensions at sites like Medway Maritime Hospital, 1.7 miles north of Chatham, usually sit beside working departments, and the mastic follows strict access rules. Hotels like Bridgewood Manor Hotel (to the south-west of Chatham) rarely close for long, so refurbishment mastic is phased floor by floor.

Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Record the products used in the O&M file
- Brief the final clean team to avoid blades near sealant
- Check frame gaps are within the sealant’s range before sealing
- Plan external elevations with the weather in mind
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead.
Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels, leaving the remedial work to the contractor. Getting the product and preparation right first time avoids that.
Common questions from Chatham clients
Do you take on work at healthcare sites like Medway Maritime Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can work at a site such as University for the Creative Arts - Rochester fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
How long does a job like this take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
What accreditations do you hold?
We’re CHAS accredited and a Constructionline member, and each applicator is CSCS-carded. Public liability insurance is in place.
Can you work while the building is occupied?
Typically, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Common problems we fix in Chatham
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly.
It’s worth sending us details if you spot any of the following:
- Different trades sealing to different standards
- Old sealant on a refurbishment that needs stripping before new work
- Caulk cracking where joints are moving more than expected
- New external sealant already peeling away
Recladding or extending a unit at a site like Horsted Retail Park, 1.1 miles west of Chatham, brings panel joints and frame perimeters into the programme.
