Construction mastic in Chestnut Street, done properly
Site managers want applicators who turn up with the right cards and paperwork. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We work on brick and block movement joints, cladding and panel joints and internal decorators’ caulk, and what we are called in for most is external joints sealed in damp or cold conditions that are now failing and old sealant on a refurbishment that needs stripping before new work. Facilities teams, main contractors and managing agents in Chestnut Street tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In the countryside around places like Chestnut Street, conversion schemes put new frames into old stone, flint, brick or timber. 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.

What affects the price in Chestnut Street
Your fixed quote is built from the real scope. It takes account of:
- Access and working height
- The site’s rules and procedures
- Travel to remote or island sites
- Working within restricted access windows
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Sending details for a quote
A good diagnosis starts with the right details. Let us know:
- Asbestos survey details if the building is older
- Whether the building will be occupied during the work
- Where the site is, with the postcode
- Clear photographs of the problem areas
Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, phone 01277 525 020 or email drawings and photos.
How a job runs
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Chestnut Street need work, visits can be combined. A fixed quote is given before anything starts.
- We price from the drawings, specification and programme you send.
- A fixed quote sets out the scope, the products and the sequence.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
What we need from you
- Send your site hours and access windows
- Point out parking and an unloading spot
- Send asbestos survey details if the building is pre-2000
Request a quote
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

What else we do in Chestnut Street
Keeping the joints sound
Regular inspection catches problems early. Specifically:
- Don’t force external sealing on a damp or frosty day
- Release areas for mastic once other trades have finished in them
- Protect sealed areas from following trades
- Put any product change through the designer first
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last, so the installer needs to correct it first. We flag them as soon as we see them.
What happens if it’s left?
A cheaper sealant can look like an easy saving on a large package. A failed joint in the defects period costs far more than the product difference and external joints are where it shows first. Where an alternative is genuinely suitable, we’ll say so. One visit to deal with every failing joint makes more sense than several trips to a place like Chestnut Street. Photos of every joint help us quote for the whole job.
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.
Why clients in Chestnut Street choose us

See how commercial sealant jobs are priced or our accreditations.
Common problems we fix in Chestnut Street
Wide, tapered or inconsistent gaps around frames are a common problem. Every product has limits on how wide a joint it can bridge. We flag them early rather than filling them with sealant that won’t last.
What tends to prompt an enquiry:
- Existing joints on a refurb that need cutting out and resealing
- Window and door perimeters that won’t pass inspection
- Mastic snags holding up handover
- Perimeter gaps outside the sealant’s range
On a healthcare site such as Sittingbourne Memorial Hospital, 2.1 miles to the east of Chestnut Street, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
What to look for in a quote
- Proof of insurance
- The named product and why it was chosen
- Will CSCS-carded applicators be on site?
- Will failed sealant be removed rather than covered?
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Specifying the product where the designer hasn’t
- Damage to finishes by other trades after we have sealed
- Defective windows, doors or glazing units (the supplier or installer’s job)
If you are not sure, just phone 01277 525 020 or send details through our quote form and we will give you a straight answer.
Surfaces we seal
- Brick and block movement joints
- Floor and skirting junctions
- Cladding and panel joints
- Sanitary and kitchen joints
- Internal decorators’ caulk
- Window and door perimeters
Construction mastic in Chestnut Street: the local picture
Chestnut Street lies within about 3 miles of the sea. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Chestnut Street is about 36 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.
For contractors at a college like Sittingbourne College (1.4 miles south-east of Chestnut Street), perimeters and internal sealant are timed for the holidays. When a school such as Borden Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.
Chestnut Street is about 2 miles west of Sittingbourne, in Kent. Anywhere in ME9, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Kent, 931 places are covered, Chestnut Street among them. London is covered too, some 36 miles away.

Common questions from Chestnut Street clients
Can you work around term dates at a campus such as Sittingbourne College?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is Chestnut Street too small for you to travel to?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
How do I request a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or send photos by email. Include photographs or drawings if you have them.
Can you seal external joints in wet or cold weather?
Weather matters for external sealing: each sealant has a temperature range, and the joint must be dry. We plan external elevations with that in mind.
What guarantee comes with a mastic package?
It carries a 12-month guarantee on our workmanship. We’re also fully insured for public liability.
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.
Do you use the sealant named in the specification?
The specification decides the product and flag anything that doesn’t look right for the joint. Product standards such as BS EN 15651 are often named in specifications.
