About our commercial sealant contractors in Colt's Hill
Mastic Doctor has been sealing joints for businesses and contractors since 2005: we are CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. We work on floor and threshold joints, movement joints in walls and floors and kitchen worktops and splashbacks, and what we are called in for most is frame mastic that has hardened and come away from the wall and damp patches where an external joint has failed. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Colt's Hill is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
A lot of what we do in Colt's Hill is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
Commercial sealant work around smaller places like Colt's Hill tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Each has kitchens, washrooms and frames whose joints need renewing in time.
Every job we finish is backed by a 12-month workmanship guarantee, in Colt's Hill as everywhere else we work. If our installation lets you down in that time, we return and fix it.

What we can’t put right
Being straight saves everyone time. New sealant won’t cure:
- Leaks from pipework, wastes or valves (that’s plumbing)
- Walls or slabs moving more than any sealant can take
- A failed roof covering or waterproofing membrane
If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think.

Working on commercial sites near Colt's Hill
Colt's Hill is in the South East, one of the UK’s drier regions. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. Colt's Hill has at least three named business or industrial parks inside a 3-mile radius. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal, often in a colour the occupier specifies.
Sites a few miles apart, such as Eldon Way Industrial Estate and Forstal Business Park, can share one programme and one point of contact. If you run a unit on an estate such as Eldon Way Industrial Estate (1.3 miles north-east of Colt's Hill), the trade counter, offices and staff facilities have joints to look after as well as the warehouse. Offices and shops close to stations such as Paddock Wood station, 1.5 miles north-east of Colt's Hill, tend to be busy all day, so sealant work is planned around opening hours.
Colt's Hill is about 4 miles south-east of Tonbridge, in Kent. If you’re looking for commercial sealant contractors in Colt's Hill, we can help. Colt's Hill is one of 931 places in Kent on our list for sealant joints. There’s a separate page for London, roughly 30 miles from Colt's Hill.

When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
FAQs: Colt's Hill
Is a smaller place like Colt's Hill outside your area?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Can you supply sealant in our brand colour for a site in Colt's Hill?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Available colours for the product are confirmed with the quote.
Is your work guaranteed?
The work is guaranteed for 12 months. Should anything we did fail within that period, let us know.
How is commercial sealant work priced?
Start with whatever information is to hand. Questions or a site visit follow where needed.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Will the building have to shut during the work?
Phased work can be planned so areas stay in use. We plan around the site hours and access windows you give us.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
What sets the cost
What shapes the price:
- The total length or number of joints
- Travel to remote or island sites
- Phasing around occupants
- Access and working height
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- Drawings or a marked-up plan, if available
- What the building is and how it’s used
- A wide shot and a close-up of the area
- Whether an asbestos survey exists
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
Looking after the joints
For the best life from the joints:
- Note dates and locations of sealant work for future planning
- Keep washroom and kitchen extraction working
- Act on the first lifting edges rather than waiting
- Ask cleaners to use a soft cloth and mild cleaner on sealant
Put sealant on the planned maintenance checklist. Regular checks pick up small failures before they become leaks. Should something look amiss, you can call the office on 01277 525 020 or send photos by email and send a picture.
Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. That turns a sealant job into something bigger.
Commercial clients in Colt's Hill
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
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.
From enquiry to sign-off
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes part of a day on a small job and longer where several buildings or phases are involved. Rural sites near Colt's Hill may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
