How a job runs
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Chestfield, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
What we need from you
- Point out parking and an unloading spot
- Tell us your opening times and when work is allowed
- Tell us which areas need to stay in use

How we handle facade sealing in Chestfield
External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. Site teams most often ask us about perimeter sealant that has split or peeled away and cold air coming in at window perimeters, across cladding panel joints, stone and brick facade joints and perimeter joints where frames meet the structure. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Chestfield is the same: the right product in a properly prepared joint.
Around smaller places like Chestfield, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
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 spell out the cover before we begin.

Aftercare for building managers
After handover, a little attention goes a long way:
- Brief window cleaners about newly sealed joints
- Record the product and colour used on each elevation
- Plan facade sealing alongside redecoration
- Inspect facade joints on a regular cycle
After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.
Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
Facade sealing in Chestfield: the local picture
With the shore within about 1 mile, Chestfield counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so joint design, primers and product choice deserve extra care. Chestfield lies roughly 51 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.
For contractors on a campus like University of Kent (4.1 miles south of Chestfield), facade and perimeter sealing has to fit around students and term dates. Units on estates such as John Wilson Industrial Estate (under half a mile west of Chestfield) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. For a contractor at a hotel such as The Marine Hotel (1.1 miles north-west of Chestfield), the mastic often has to be finished before a reopening date.

Why it’s worth doing now in Chestfield
Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple. For buildings around smaller places like Chestfield, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Questions we are asked in Chestfield
Our building in Chestfield is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is Chestfield too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Can you just add new sealant on top?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely. Nothing else gives a bond that lasts.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
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.
When is resealing likely to be due?
Nobody can honestly give a figure in years, 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.
Can you work while the building is occupied?
Typically, yes. Phased work can be planned so areas stay in use.
How the quote is worked out
The price varies from site to site. Expect it to depend on:
- The product specified
- Induction, permit and paperwork requirements
- Quantities, in metres or numbers
- Access and working height
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Sending details for a quote
Good information means a firmer quote. When you get in touch, include:
- Anything awkward about access or site hours
- Whether the building will be occupied during the work
- Where the site is, with the postcode
- Whether an asbestos survey exists
Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, speak to us on 01277 525 020 or send details through our quote form.
What the job involves on each surface
Precast concrete panels
Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.
Render and coated surfaces
Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.
