General trades versus 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.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
About our construction mastic in Stone Street
On a new build, the mastic package is one of the last trades through each area. We work as a mastic subcontractor to main contractors and developers on schemes in Stone Street. We work on internal decorators’ caulk, sanitary and kitchen joints and window and door perimeters, and the usual reasons a site gets in touch are early adhesion failures on new external joints and a mastic package split between trades with no clear owner. A single leaking joint is often how a building in Stone Street first comes to us: we look at the rest while we are there and tell you what we find.
Conversions of older rural buildings near smaller places such as Stone Street bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
We stand by our work with a 12-month guarantee. That covers our preparation and application.

Sites and facades in and around Stone Street
Stone Street is about 22 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. Rainfall across the South East, Stone Street included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.
When units on a site such as Chaucer Business Park (1.9 miles north of Stone Street) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. When a school such as St Lawrence Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

What affects the price in Stone Street
The price varies from site to site. Expect it to depend on:
- The site’s rules and procedures
- Removal of failed or old sealant
- Backing rod, priming and other preparation
- How accessible the joints are
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
What to include in your enquiry
Whether it’s one area or a whole building, the same details help:
- Photos of the joints, close up and from further back
- Specification clauses that apply
- Asbestos survey details if the building is older
- Where the site is, with the postcode
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Work for main contractors and building owners
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
On site: what to expect
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Smaller jobs around Stone Street can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.

Do you need construction mastic in Stone Street?
Shrinkage and settlement in the first months put new joints under strain. Materials lose construction moisture and shrink. Picking a flexible sealant where there’s movement keeps snags down.
It’s worth sending us details if you spot any of the following:
- Missed perimeter joints on a new elevation
- Cracks opening in caulked internal joints
- Bath and shower joints scraped during the final clean
- Old sealant on a refurbishment that needs stripping before new work
Historic houses such as Ightham Mote (1.1 miles south-east of Stone Street) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Why deal with it now?
Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go. We can run snagging as its own phase before handover. Converted and older buildings near places like Stone Street tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote when you are ready.

Stone Street: questions and answers
Do you cover business parks and estates near Stone Street, such as Chaucer Business Park?
Yes. Our area takes in Stone Street and its surroundings, with estates and business parks such as Chaucer Business Park included. Photos and a short description are enough for a first look.
Do you take on work at healthcare sites like Cygnet Hospital Godden Green?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
How much does the work cost?
That depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
What site paperwork can you supply?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
How long does a job like this take?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
