How we handle mastic sealing in Cliffe
Owners and agents typically inherit a building’s mastic rather than choose it and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. The enquiries we see most involve worn sealant at communal door frames and patchy repairs in mismatched sealant, on shopfronts below residential blocks, window and door perimeters on blocks and balcony and threshold joints. A specialist sealant contractor works differently from a general builder: in Cliffe, that means joint design, primers and backing rod as standard.
Owners and agents with buildings around smaller places such as Cliffe tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Aftercare for building managers
A few simple habits keep the new joints working:
- Prioritise elevations facing the weather
- Keep bins and bikes away from communal door frames
- List the paperwork your organisation requires when you send details
- Avoid piecemeal callouts where you can
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and saves internal repairs.
FAQs: Cliffe
Do you work for managing agents with blocks near Higham station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
Is Cliffe too small for you to travel to?
Not at all. Cliffe is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Can you plan resealing across several buildings?
We can. We survey and price each building, then work through them in order, and the programme can start with the worst.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
How do you handle work on occupied blocks?
The work is planned around occupiers. We agree the programme so you can notify occupiers, and entrances stay in use.
Common problems we fix in Cliffe
Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant, so these repairs rarely last.
What tends to prompt an enquiry:
- Damp patches beside frames
- Complaints coming in block by block
- A mix of products and colours from past repairs
- Movement joints with sealant missing
Student accommodation around universities such as University of Greenwich - Medway (to the south-east of Cliffe) is typically managed block by block, which suits a planned mastic programme.

Looking after buildings in and around Cliffe
With the shore within about 2 miles, Cliffe counts as a coastal location. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, and they deserve more regular inspection. At about 26 miles from central London, Cliffe is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide.
Churches, halls and community buildings such as Church of St Helen are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Buildings close to stations like Higham station (to the south-west of Cliffe) are often flats over shops, with frame mastic to keep sound.

What sets the cost
Quotes vary with the job. Expect it to depend on:
- Site requirements such as inductions and permits
- How accessible the joints are
- The size and state of each joint
- The product specified
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Sending details for a quote
Whether it’s one area or a whole building, the same details help:
- Any specification or named product
- The asbestos register, for older buildings
- Approximate linear metres or a joint schedule
- The site address and postcode

Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
