About our mastic sealing in Chalk
Older blocks and commercial buildings can have mastic that contains 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. We work on communal kitchens and washrooms, external wall and movement joints and balcony and threshold joints, and the failures we are asked to look at most are complaints coming in block by block and draught complaints from residents or tenants. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Chalk is the same: the right product in a properly prepared joint.
For owners with a single building near Chalk, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

From enquiry to sign-off
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. For a building around Chalk, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Before we start on site

Questions we’re asked in Chalk
Does your area include sites such as Lion Business Park, near Chalk?
Yes, sites like Lion Business Park are within our area, along with the rest of Chalk. A few photographs and the unit address let us price the work.
Is Chalk off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Cost factors for mastic joints
Each job is priced on its own details. The main factors are:
- Access and working height
- Induction, permit and paperwork requirements
- How much there is to seal
- Location, for remote and island sites
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote when you are ready.
What we need to price the job
A good diagnosis starts with the right details. Tell us:
- Photos of the joints, close up and from further back
- Specification clauses that apply
- Where the site is, with the postcode
- Any dates the work must fit around
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to give us a call on 01277 525 020 or email drawings and photos with what you know.
What happens if it’s left?
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. Converted and older buildings near places like Chalk tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Looking after buildings in and around Chalk
With the shore within about 2 miles, Chalk counts as a coastal location. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, so it’s worth inspecting those sides more often. Chalk is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
For owners of several units at places like Lion Business Park, which lies north-west of Chalk, one programme can deal with frame and external mastic across the lot. Buildings close to stations like Gravesend station (to the west of Chalk) are often flats over shops, with frame mastic to keep sound. For a school such as Thamesview School, perimeter mastic on windows and doors is a holiday job.
Chalk is about 1 mile east of Gravesend, in Kent. Anywhere in DA12, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Chalk is one of 931 places in Kent on our list. Our London page has more on work in that area.
Anyone looking for mastic sealing in DA12 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

What we can’t put right
Some faults sit outside our scope, and we say so rather than covering them up:
- Glazing that needs replacing
- Leaks from above rather than through a joint
- Frames that are rotten, warped or broken
Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Balcony and threshold joints
- Shopfronts below residential blocks
- External wall and movement joints
After the work
A few simple habits keep the new joints working:
- Plan resealing building by building rather than complaint by complaint
- Look at the sunniest and most exposed elevations first
- Track which buildings were done and when
- Make mastic part of routine maintenance checks
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and the complaints that come with it.
Site staff or a sealant specialist?
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.
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.
