What sealant work can’t fix
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Approving fire stopping as compliant
- Faulty frames rather than failed sealant
- Joints damaged after sign-off by following trades
Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

How we handle construction mastic in Jarvis Brook
Perimeter sealing outside needs a dry joint and the right temperature. Each sealant has a temperature range, and damp, frost or condensation on frames stops work so it helps to sequence elevations with some flexibility. Internal areas can normally carry on while the outside waits. If you have failed sealant in an existing building being refurbished and a long mastic snag list close to completion, we can help, on sanitary and kitchen joints, window and door perimeters and floor and skirting junctions alike. A single leaking joint is often how a building in Jarvis Brook 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 Jarvis Brook 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.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Aftercare for building managers
Cleaning and maintenance staff play a part too. Pass these on to them:
- Use the product the specification names
- Note which sealant went where at handover
- Check frame gaps are within the sealant’s range before sealing
- Ask cleaners to use soft cloths around fresh sealant
If a joint is damaged after sealing, flag it early. We can return to clear snags before handover, priced as part of the package or separately.
External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks so external sequencing builds in some flexibility.

Mastic packages on Jarvis Brook sites
Jarvis Brook lies roughly 33 miles out 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. Jarvis Brook sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.
On a healthcare site such as Crowborough War Memorial Hospital, which lies west of Jarvis Brook, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. When a school such as Jarvis Brook Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.
Jarvis Brook is about 1 mile east of Crowborough, in East Sussex. If you’re looking for construction mastic in Jarvis Brook, we can help, as we do across East Sussex. Our East Sussex coverage takes in 308 places. For work in that direction, see our Brighton page.

What we’re called out for in Jarvis Brook
On a live site, contamination is the biggest threat to a new joint. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
Most enquiries start with something like this:
- External joints sealed in damp or cold conditions that are now failing
- Failed sealant in an existing building being refurbished
- Internal caulk splitting as the building dries out
- Inconsistent sealant finishes from plot to plot
Recladding or extending a unit at a site like Lexden Lodge Industrial Estate, under half a mile to the south-east of Jarvis Brook, brings panel joints and frame perimeters into the programme.

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, with the work itself usually taking whatever the programme allows, since the work follows the trades as areas are released. If others near Jarvis Brook need work, visits can be combined. A fixed quote is given before anything starts.
- First we take quantities off the drawings and read through the specification.
- We return a fixed quote that ties the mastic package to your programme.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.

- Snags are cleared before handover and completed areas carry our 12-month guarantee.

Why deal with it now?
A quick bead over a damaged joint can get an area past inspection. Sealant can’t grip a contaminated or existing bead and the defect reappears in the defects period. We cut out and redo the joint properly. One visit to deal with every failing joint makes more sense than several trips to a place like Jarvis Brook, rather than one at a time. Photos of every joint help us quote for the whole job.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

Questions we are asked in Jarvis Brook
Can you work at a site such as Lexden Lodge Industrial Estate, by Jarvis Brook?
Yes, sites like Lexden Lodge Industrial Estate are within our area, along with the rest of Jarvis Brook. Send details of the unit and the work through our quote form for a quick quote.
Is Jarvis Brook too small for you to travel to?
No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Is the mastic package guaranteed?
It carries a 12-month guarantee on our workmanship. We carry five million pounds of public liability insurance.
What will the job cost?
We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.
How do you work with the site programme?
Our work is sequenced around the programme. Areas are sealed as they’re released by the site team.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
