About our mastic sealing in Postling Green
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint. We’ll confirm the colours available for the specified product. Site teams most often ask us about failed external movement joints and a mix of products and colours from past repairs, on communal entrances and stairwells, balcony and threshold joints and shopfronts below residential blocks. Whoever orders the work in Postling Green, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like Postling Green, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
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.

Different surfaces, different methods
Planned maintenance
Adding mastic to planned maintenance avoids reactive repairs and spreads the work.
Tenement and older buildings
Traditional buildings have joints that need a careful approach. We look at the substrate before choosing a sealant.
Block-wide mastic in Postling Green
The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Postling Green lies roughly 54 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate.
Historic properties like Westenhanger Castle, 3.2 miles to the east of Postling Green, show the age of some local stock, where frame mastic must suit soft brick or stone. If you’re responsible for a building such as Church of St Martin, frame and door mastic needs the same attention as any other property.

On site: what to expect

Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints. Rural sites near Postling Green may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- 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.
- Failed sealant is removed and the faces prepared.
- New sealant goes in with backing rod and primer where needed.

Preparing the site

What else we do in Postling Green
Aftercare for building managers
After handover, these steps help:
- Make mastic part of routine maintenance checks
- Start inspections with the most exposed faces
- List the paperwork your organisation requires when you send details
- Ask residents or tenants to report leaks and draughts early
Keep records of when each building was resealed. It helps plan the next round and gives you a history.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings and work down the list.
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Broken glass or failed sealed units
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Water coming in from the roof or rainwater goods
If you are not sure, just speak to us on 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

Your questions answered
Is Postling Green off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Will you take on work at estates like Evegate Business Park, close to Postling Green?
Yes, sites like Evegate Business Park are within our area, along with the rest of Postling Green. A few photos and the unit address let us price the work.
How do I request a quote?
You can use the quote form on this site; alternatively, call the office on 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Do you work for managing agents and housing associations?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
What about access for upper-floor joints?
Every block is different. We agree access with you at quote stage so there are no surprises.
Signs you need mastic sealing in Postling Green
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.
These are often picked up first by site or facilities staff:
- Damp patches beside frames
- Cracked, hardened mastic round windows on a block
- The same joint failures repeated across a portfolio
- Failed external movement joints
Property owners at sites such as Evegate Business Park, 2.2 miles north of Postling Green, can have mastic renewed between lettings.
Questions to ask before you book
- How joint depth will be controlled
- How the existing material will be dealt with
- Whether their applicators hold CSCS cards
- How the joint faces will be prepared and primed
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
