Mastic sealing across Stone Street
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Mastic sealing in Stone Street
For blocks and buildings in Stone Street and across Kent, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. The enquiries we see most involve the same joint failures repeated across a portfolio and old repairs sealed over failed mastic, on communal entrances and stairwells, external wall and movement joints and communal kitchens and washrooms. Facilities teams, main contractors and managing agents in Stone Street tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For buildings around smaller places like Stone Street, we group work so one trip covers it. Send photographs of the frames and joints and we’ll give a fixed quote.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Questions about Stone Street
Is Stone Street off your patch?
Not at all. Stone Street is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Is Chaucer Business Park, near Stone Street, within your area?
Yes. Our area takes in Stone Street and its surroundings, with estates and business parks such as Chaucer Business Park included. A few photographs and the unit address let us price the work.
Can you send RAMS and CSCS details before starting?
We are CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
How do you handle work on occupied blocks?
Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so it can be arranged.
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. We work through buildings in a planned order so you can plan around it.
Block-wide mastic in Stone Street
The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. At about 22 miles from central London, Stone Street is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate.
With historic buildings such as Ightham Mote, 1.1 miles south-east of Stone Street, in the wider area, owners of older properties around Stone Street should expect mastic to need a product that suits old masonry. If you own or manage units on a site such as Chaucer Business Park (1.9 miles north of Stone Street), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Trustees of buildings like St Lawrence can bring frame and external mastic into a planned maintenance list.
Stone Street is about 3 miles east of Sevenoaks, in Kent. We cover Stone Street, with the same fixed quotes and 12-month guarantee as everywhere else. Stone Street is one of 931 places we cover in Kent for mastic joints. Our London page has more on work in that area.

How the quote is worked out
A fixed quote reflects the actual work. It allows for:
- Site requirements such as inductions and permits
- Whether the work must be split into stages
- Distance, for remote addresses
- Backing rod, priming and other preparation
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
Details that help us quote
A good diagnosis starts with the right details. Let us know:
- Whether an asbestos survey exists
- The product your specification calls for
- Any dates the work must fit around
- A wide shot and a close-up of the area
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or email the details over.
Site staff or a sealant specialist?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Leave it or put it right?
Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Around Stone Street, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.
A quote for mastic joints depends on how many there are, their condition and the access. Call for a quote.

On site: what to expect
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Stone Street may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- Joints are resealed and tooled.
- We check the finished work and confirm the guarantee.
Getting the site ready
- Tell us which areas need to stay in use
- Send asbestos survey details if the building is pre-2000
- Point out parking and an unloading spot

When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Broken glass or failed sealed units
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly.
Surfaces we seal
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Balcony and threshold joints
- External wall and movement joints
- Window and door perimeters on blocks
- Shopfronts below residential blocks
