About our mastic sealing in Waltham
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. We work on window and door perimeters on blocks, external wall and movement joints and communal kitchens and washrooms, and the usual reasons a site gets in touch are leaks at window and door perimeters and repeated reactive repairs to the same buildings. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Waltham it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Owners and agents with buildings around smaller places such as Waltham 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.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Leave it or put it right?
Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish. Halls, stores and units around places like Waltham may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
We don’t publish prices, since every building and every scope is different. Call for a quote.

Questions about Waltham
Can one quote cover a number of our buildings near Waltham?
Yes. Planned programmes across a building, block or estate are a core part of this service. Send the addresses and photographs and we will give a fixed quote.
Is Waltham off your patch?
No. Places such as Waltham are covered as much as the big towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
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.
What paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Do you work with property factors and landlords?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Cost factors for mastic joints
Before we quote, we look at:
- How much there is to seal
- Access and working height
- Joint width, depth and condition
- How much existing material needs removing
Pricing mastic joints depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.
What to include in your enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- Where the site is, with the postcode
- Any dates the work must fit around
- Specification clauses that apply
- Asbestos survey details if the building is older
For a fixed quote, give us a call on 01277 525 020 or email the details over. Our quote form is another easy route.
Mastic sealing around Waltham: what changes locally
At about 52 miles from central London, Waltham is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.
Blocks of flats and mixed-use buildings often cluster around stations such as Chilham station (to the north-west of Waltham) and their window and balcony mastic tends to age at the same rate across a building.
Waltham is about 6 miles south-west of Canterbury, in Kent. Our applicators travel to Waltham for work on mastic joints. Waltham is one of 931 places we cover in Kent. We also cover London, some 52 miles away.
If you need mastic sealing in CT4, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. If your site is on Church Lane, Richdore Road and Kake Street or close by, send details and we will quote for mastic joints. Sites close to Waltham are covered too, including Stelling Minnis (2 miles east), Bossingham (2 miles east), Stowting Common (4 miles south), Stowting (4 miles south) and Rhodes Minnis (4 miles south-east). Nearby towns on our patch include Ashford (8 miles south-west), Canterbury (6 miles north-east), Dover (13 miles east), Folkestone (10 miles south-east), Whitstable (11 miles north) and Faversham (10 miles north-west).

When to call us in Waltham
The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
Site and facilities staff are often the first to spot these:
- A mix of products and colours from past repairs
- Worn sealant at communal door frames
- Draught complaints from residents or tenants
- Window mastic that has split and shrunk
Older community buildings, Church of St Bartholomew among them, often have frames of mixed ages whose mastic varies.
Questions to ask before you book
- What site paperwork they can supply
- How they’ll work around occupants
- How the joint faces will be prepared and primed
- The terms of the workmanship guarantee

On site: what to expect
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Waltham 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.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
Before we start on site

Ask for a quote
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Looking after the joints
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Protect low-level joints in entrances
- Encourage occupiers to report problems at frames
- Keep a record of when each building was resealed
- Plan resealing building by building rather than complaint by complaint
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.
