Facades, frames and programmes in Colt's Hill
Rainfall across the South East, Colt's Hill included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. At about 30 miles from central London, Colt's Hill is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.
On a campus such as University of Kent - Tonbridge, 4.1 miles to the west of Colt's Hill, new teaching buildings and residences are typically built and refurbished around the academic year. When a school such as Capel Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.
Colt's Hill is about 4 miles south-east of Tonbridge, in Kent. Businesses, contractors and managing agents in Colt's Hill can call on us for mastic packages, as part of our coverage of Kent. Across Kent, 931 places are covered, Colt's Hill among them. We also cover London, some 30 miles away.

About our construction mastic in Colt's Hill
The specification and the programme set the job. If a product is named, that’s what goes in. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. If you have caulk cracking where joints are moving more than expected and mastic snags holding up handover, we can help. A specialist sealant contractor works differently from a general builder: in Colt's Hill, that means joint design, primers and backing rod as standard.
Conversions of older rural buildings near smaller places such as Colt's Hill bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Advice
When it isn’t the sealant
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Specifying the product where the designer hasn’t
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Rework caused by others damaging completed areas
If you’re not sure, just ring 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.
Surfaces we seal
- Floor and skirting junctions
- Window and door perimeters
- Internal decorators’ caulk
- Cladding and panel joints
- Brick and block movement joints
- Sanitary and kitchen joints
How the job changes by surface
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification and set the depth with backing where needed.
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. A single team keeps the standard consistent, plot by plot or floor by floor.
When to call us in Colt's Hill
A joint without backing rod or bond-breaker often fails early. Fixed to three faces, the sealant rips the first time the joint opens.
Any of the following is a good reason to get the joints checked over:
- Mastic snags holding up handover
- External joints sealed in damp or cold conditions that are now failing
- Different trades sealing to different standards
- Old sealant on a refurbishment that needs stripping before new work
Recladding or extending a unit at a site like Eldon Way Industrial Estate, 1.3 miles to the north-east of Colt's Hill, brings panel joints and frame perimeters into the programme.

Quoting for work in Colt's Hill
To price the job, we consider:
- Site requirements such as inductions and permits
- How accessible the joints are
- Quantities, in metres or numbers
- The size and state of each joint
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
What we need to price the job
We can often quote from photographs and a few details. It helps to include:
- How the joints are reached, and at what height
- Where the site is, with the postcode
- A wide shot and a close-up of the area
- The product your specification calls for
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or use the quote form.
Why deal with it now?
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple, with the same standard on every plot. Converted and older buildings near places like Colt's Hill tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.
Why us?
- Workmanship guaranteed for 12 months
- Colour options checked against the specified product
- Constructionline member for supplier checks
- Matching to RAL references, product permitting

Questions we’re asked in Colt's Hill
Can work at a site such as University of Kent - Tonbridge fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Eldon Way Industrial Estate, near Colt's Hill, within your area?
Yes. We cover Colt's Hill and the area around it, including industrial estates, business parks and retail parks such as Eldon Way Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
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. Removing asbestos is a job for asbestos specialists, not us.
Do you take on mastic snagging only?
Yes, we can. Share the list and photographs, and a fixed quote follows.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Will you come and look before quoting?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs usually get a visit.
