Mastic sealing in Bicknor
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. We work on window and door perimeters on blocks, shopfronts below residential blocks and external wall and movement joints, and the failures we are asked to look at most are repeated reactive repairs to the same buildings and movement joints with sealant missing. Searching for sealant specialists in Bicknor? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
For owners with a single building near Bicknor, we plan to finish in one visit where possible. Send photographs of the frames and joints and we’ll give a fixed quote.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

What sets the cost
To price the job, we consider:
- Backing rod, priming and other preparation
- Travel to remote or island sites
- How much there is to seal
- Specialist products, such as fire-rated or hygienic sealants
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.
Details that help us quote
We can often quote from photographs and a few details. Please tell us:
- Access details, including height
- Specification clauses that apply
- What the building is and how it’s used
- Your programme or deadline
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or send photos by email.
How the job changes by surface
Estate-wide resealing programmes
Housing associations and agents often manage many similar blocks. Each block is priced and scheduled in order.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Our process
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Jobs in and around smaller places like Bicknor are typically planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Old mastic is removed and the joint faces prepared.
- Joints are resealed and tooled.
- We check the finished work and confirm the guarantee.
What we need from you
- Share the asbestos register for older buildings
- Flag any permit to work we will need
- Confirm the product named in the specification
Quotes
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or send details through our quote form to discuss it first.

Questions about Bicknor
Do you work for managing agents with blocks near Hollingbourne station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
Is Bicknor too small for you to travel to?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
What paperwork can you provide?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
Can you seal joints high up on a block?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned, and we’ll tell you how we’d approach it.
Maintenance after handover
To get the most from the new sealant:
- Keep bins and bikes away from communal door frames
- Make mastic part of routine maintenance checks
- Group repairs into a planned programme
- Ask residents or tenants to report leaks and draughts early
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and the complaints that come with it.
Looking after buildings in and around Bicknor
Bicknor is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Central London is about 36 miles from Bicknor. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
Churches, halls and community buildings such as Church of St James are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. For owners of several units at places like Kent Science Park (2.7 miles north-east of Bicknor), one programme can deal with frame and external mastic across the lot. If you look after a block within reach of Hollingbourne station, 2.8 miles to the south-west of Bicknor, frame and balcony mastic can be renewed on one programme.

Why act early in Bicknor
A bead run over old mastic can look like a repair. It doesn’t bond and typically fails within a short time. Full removal and proper preparation is what lasts. Converted and older buildings near places like Bicknor tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
