Mastic sealing in Sandling, done properly
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. If you have damp patches beside frames and movement joints with sealant missing, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: in Sandling, that means joint design, primers and backing rod as standard.
Around smaller places like Sandling, 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.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Blocks and managed buildings in Sandling
Sandling sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. At about 30 miles from central London, Sandling is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
For agents with blocks near Maidstone East station, 1.4 miles to the south of Sandling, a block-wide mastic programme deals with frames, balconies and entrances in one go. Schools and community buildings such as Sandling Primary School need frame and external mastic kept sound like any building. Churches, halls and community buildings such as St Paul's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Sandling is about 1 mile north-west of Foley Park, in Kent. Across the ME14 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 931 places across Kent fall within our area, including Sandling. Our London page has more on work in that area, about 30 miles away.

What’s near Sandling
We work on buildings around The Yew Tree pub, Tyland Barn and The Maplesden Noakes School, among other places. For rail, the closest station is Maidstone East station, roughly 1.4 miles south. A little further out are KIMS hospital (2 miles south-east) and Allington Castle (less than half a mile south-west). Green spaces nearby include Burham Down and Boxley Hills.
General trades versus a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
A short, simple internal joint is often within reach of a maintenance team. 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.
Cost factors for mastic joints
What shapes the price:
- Phasing around occupants
- Joint width, depth and condition
- Distance, for remote addresses
- Site requirements such as inductions and permits
We don’t publish prices, since every building and every scope is different. Call for a quote.
Before you send an enquiry
We can often quote from photographs and a few details. Please tell us:
- Any specification or named product
- Clear photos of the problem areas
- What the building is and how it’s used
- Rough lengths or quantities, or drawings if you have them
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Sandling: questions and answers
Is a smaller place like Sandling outside your area?
No. Small places get the same service as large ones. 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.
Do you cover business parks and estates near Sandling, such as Viewpoint Industrial Estate?
Yes. Our area takes in Sandling and its surroundings, with estates and business parks such as Viewpoint Industrial Estate included. Photos and a short description are enough for a first look.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
How do I request a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
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 we quote building by building or as a programme.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Why act early in Sandling
Reacting to every complaint means sending someone out block by block. A planned programme treats each building once, under a single quote and a single programme. One visit to deal with every failing joint makes more sense than several trips to a place like Sandling. Photos of every joint help us quote for the whole job.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Why us?
- Failed material removed, not covered up
- CSCS-carded applicators
- 12 months’ guarantee on every job
- Constructionline member for supplier checks
On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Smaller jobs around Sandling can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
Preparing the site
- Agree which areas must stay open
- Let building users know which areas are affected
- Clear stock, furniture or equipment away from the joints
Request a quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Keeping the joints sound
Once the work is signed off, these steps help:
- Start inspections with the most exposed faces
- Check the asbestos register before any old mastic is disturbed
- Include mastic in your cyclical inspections
- Keep bins and bikes away from communal door frames
Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings and work down the list.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Substrate edges that need repairing first
- Glazing that needs replacing
- Leaks from above rather than through a joint
If in doubt, speak to us on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.
What we seal
- Shopfronts below residential blocks
