What the job involves on each surface
Cladding panel joints
On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them.
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather and need a durable external sealant.
Facade sealing in Borstal
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. We work on window and door perimeters, stone and brick facade joints and cladding panel joints, and what we are called in for most is old perimeter mastic that has dried out and failed seals around shopfront and entrance frames. A single leaking joint is often how a building in Borstal first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Conversions around smaller places like Borstal often join new frames to old masonry or timber, which leaves joints between old walls and new frames that need a sealant able to take the movement, in a colour the planners or architect are happy with.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Questions about Borstal
Can you work around term dates at a campus such as University for the Creative Arts - Rochester?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is Borstal too far out for you?
Not at all: smaller places are covered as well as towns. 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.
Do you replace failed glazing units?
No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.
Do you run new sealant over the existing bead?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the joint cleaned back to sound material. That is what makes the new joint last.
What hours do you work?
We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
What will the job cost?
Every job gets its own fixed quote. To get one, phone 01277 525 020 or email the details over with a description of the work.
Building and refurbishing in Borstal
There are a good number of hotels within about 2 miles of Borstal. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Rainfall across the South East, Borstal included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.
Hotel extensions and refits, at places such as The Dickens Hotel, 1.2 miles to the north-east of Borstal, normally run between busy periods, so the sealing is squeezed into short windows. Recladding or extending a unit at a site like Strood Retail Park (to the north of Borstal) brings panel joints and frame perimeters into the programme. On a healthcare site such as Medway Maritime Hospital, 2.4 miles to the east of Borstal, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Borstal is about 1 mile south-west of Rochester, in Medway. We send applicators to Borstal for facade joints. Borstal is one of 54 places we cover in Medway. Our London page has more on work in that area.
We cover the ME1 and ME2 postcode districts. Buildings on Hill Road, Manor Lane and Mount Road are within our area for facade joints. With the M2 nearby, Borstal is easy to get to with materials and equipment. Nearby places we also cover include Rochester (1 mile north-east), Strood (1 mile north), Cuxton (1 mile west), North Halling (2 miles west) and Wouldham (2 miles south-west) for facade joints. Nearby towns on our patch include Gillingham (4 miles east), Rainham (5 miles east), Park Wood (5 miles east), Lordswood (4 miles south-east), Twydall (4 miles east) and Hoo St Werburgh (5 miles north-east).
What’s near Borstal
Around Borstal, our work takes us to commercial buildings near Sir Joseph Williamson's Mathematical School, Former Ordnance Store At Chatham Gun Wharf and St John Fisher RC Comprehensive School and the streets around them. The nearest railway station is Cuxton station, roughly 1 mile west of the centre. A little further out are Six Poor Travellers House (1.3 miles north-east) and Rochester Castle (1.3 miles north-east). For a walk, there’s Blue Bell Hill and Ranscombe Farm.
When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Work on the window or framing system itself
- Damaged frames that need replacing
- Leaks from roofs, gutters or failed flashings rather than sealant joints
If you’re not sure, just ring 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

Related advice
Why it’s worth doing now in Borstal
Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.
Why us?
- A Constructionline member, so easy to vet
- Matching to RAL references, product permitting
- Colours confirmed for the specified product
- CHAS accredited contractor
After the work
Regular inspection catches problems early. In particular:
- Plan facade sealing alongside redecoration
- Clear debris that holds water against joints
- Confirm the survey covers external sealants in older buildings
- Keep pressure washers away from fresh sealant
Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly with a compatible product.
Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail, rather than waiting for a ceiling stain.
What affects the price in Borstal
Before we quote, we look at:
- Travel to remote or island sites
- Joint width, depth and condition
- The site’s rules and procedures
- Phasing around occupants
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.
Details that help us quote
It doesn’t need to be a full survey. A few details are enough to get going:
- The postcode of the building
- When you need the work done
- Rough lengths or quantities, or drawings if you have them
- Any specification or named product
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email us.
