How we handle mastic sealing in Ebbsfleet
Before work starts, most agents and landlords want the documents in order. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. We work on window and door perimeters on blocks, external wall and movement joints and shopfronts below residential blocks, and the failures we’re asked to look at most are leaks at window and door perimeters and old repairs sealed over failed mastic. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Ebbsfleet it comes down to the same thing: the right product in a properly prepared joint.
Around smaller places like Ebbsfleet, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Common questions from Ebbsfleet clients
Is Ebbsfleet too small for you to travel to?
No. Places such as Ebbsfleet are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Will you take on a block within reach of Thanet Parkway station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Do you supply RAMS and insurance details?
We are CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
What guarantee do you give on resealing?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
How do you handle work on occupied blocks?
The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.
How many days will you need on site?
It depends on the scope, but the work normally takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we will give you a timescale with the quote.

How the quote is worked out
A fixed quote reflects the actual work. It allows for:
- Removal of failed or old sealant
- Quantities, in metres or numbers
- Which sealant the job calls for
- Phasing around occupants
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.
Details that help us quote
Whether it’s one area or a whole building, the same details help:
- How the joints are reached, and at what height
- Rough lengths or quantities, or drawings if you have them
- The asbestos register, for older buildings
- Any specification or named product
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 will fill any gaps with a visit.
Block-wide mastic in Ebbsfleet
With the shore within about 2 miles, Ebbsfleet counts as a coastal location. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, so it’s worth inspecting those sides more often. Ebbsfleet sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, 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 Thanet Parkway station (to the north-east of Ebbsfleet) and their window and balcony mastic tends to age at the same rate across a building. For owners of several units at places like Old Timber Yard Industrial Estate (2.3 miles north-east of Ebbsfleet), one programme can deal with frame and external mastic across the lot.
Ebbsfleet is about 3 miles south-west of St Lawrence, in Kent. Any commercial site in Ebbsfleet is covered, for single jobs and planned programmes alike. Ebbsfleet is one of 931 places in Kent on our list. For work in that direction, see our London page.

How a job runs
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near Ebbsfleet may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
What we need from you
- Move anything stored against the joints
- Share the asbestos register for older buildings
- Point out any areas we must not close

Honest limits
Being straight saves everyone time. New sealant won’t cure:
- Asbestos-containing sealant, which we don’t remove
- Failed window or door frames, which need a window contractor
- Leaks from above rather than through a joint
Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.
Surfaces we seal
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Shopfronts below residential blocks
- External wall and movement joints
- Communal kitchens and washrooms
- Balcony and threshold joints
Owners, agents and contractors
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
What we are called out for in Ebbsfleet
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.
Site and facilities staff are often the first to spot these:
- Mastic failing across several blocks on an estate
- Draughts at frames across a block
- No planned programme for sealant
- Window mastic that has split and shrunk
With historic buildings such as Quex Park (to the north of Ebbsfleet) in the wider area, owners of older properties around Ebbsfleet should expect mastic to need a product that suits old masonry.
Before you book anyone
- How the existing material will be dealt with
- Who will actually carry out the work
- What level of public liability insurance do they hold?
- What the guarantee covers, and for how long
Why deal with it now?
Sealing over failed mastic looks tidy for a while. It doesn’t bond and normally fails within a short time. Full removal and proper preparation is what lasts. Older rural buildings around Ebbsfleet move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
