Advice
About our mastic sealing in Wrotham
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. We work on balcony and threshold joints, external wall and movement joints and shopfronts below residential blocks, and the failures we are asked to look at most are brittle perimeter mastic across a building and damaged joints in communal entrances and corridors. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Wrotham, that means joint design, primers and backing rod as standard.
In and around smaller places like Wrotham, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

When to bring in a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
What sets the cost
We price every job individually. The main factors are:
- How much there is to seal
- Backing rod, priming and other preparation
- The site’s rules and procedures
- Whether the work must be split into stages
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Before you send an enquiry
However big the job, these details speed things up:
- When you need the work done
- Clear photographs of the problem areas
- The type of building and who uses it
- Access details, including height
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
How the job changes by surface
Commercial and mixed-use buildings
Commercial occupiers usually stay open during the work so the work is phased.
Planned maintenance
Planned resealing replaces emergency callouts and keeps budgets predictable.
Signs you need mastic sealing in Wrotham
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
Any of the following is a good reason to get the joints checked over:
- Occupiers reporting cold air round windows
- Brittle perimeter mastic across a building
- Repeated reactive repairs to the same buildings
- Damp patches beside frames
If your remit includes a building such as Wrotham School, frame and door mastic can be programmed for the holidays.
What your quote should include
- Their approach to joint depth and backing
- Their public liability cover
- What site paperwork they can supply
- How the joint faces will be prepared and primed
Your questions answered
Will you take on a block within reach of Borough Green & Wrotham station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Is Wrotham too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
How long does a typical visit take?
That varies with the scale of the job, but the work typically takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we’ll set out a timescale with the quote.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Can you plan resealing across several buildings?
Yes. We survey and price each building, then work through them in order, and the programme can start with the worst.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Check sealant joints during planned building inspections
- Log resealing dates block by block
- Ask residents or tenants to report leaks and draughts early
- Keep bins and bikes away from communal door frames
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.
Mastic sealing around Wrotham: points for this area
Wrotham sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Wrotham lies roughly 22 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
Landlords with units on estates such as Invicta Business Park, 0.9 miles to the east of Wrotham, can bring frame, door and external mastic across several units into one programme. If you’re responsible for a building such as Church of St George, frame and door mastic needs the same attention as any other property.
