About our mastic sealing in Great Chart
Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. If you are dealing with draught complaints from residents or tenants and cracked, hardened mastic round windows on a block, we can help, on shopfronts below residential blocks, external wall and movement joints and communal entrances and stairwells alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Great Chart is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In and around smaller places like Great Chart, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or send details through our quote form and we’ll come back to it.

General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
What affects the price in Great Chart
The price varies from site to site. It mainly depends on:
- Any access equipment needed
- The site’s rules and procedures
- How much existing material needs removing
- Whether the work must be split into stages
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 we will put a fixed figure on it.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- A wide shot and a close-up of the area
- Where the site is, with the postcode
- Anything awkward about access or site hours
- Asbestos survey details if the building is older
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email us.
Why it’s worth doing now in Great Chart
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. Converted and older buildings near places like Great Chart tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Common questions from Great Chart clients
Can you work at a site such as St. Georges Business Centre, by Great Chart?
Yes, sites like St. Georges Business Centre are within our area, along with the rest of Great Chart. A few photographs and the unit address let us price the work.
Will you take on a block within reach of Ashford International station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
What about access for upper-floor joints?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place and we’ll confirm the approach in the quote.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How many days will you need on site?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Do you work for managing agents and housing associations?
Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
How a job runs
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For work around Great Chart, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We inspect the joints, building by building, and record what has failed and why.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
What we need from you
- Explain the parking and delivery arrangements
- Send asbestos survey details if the building is pre-2000
- Send any specification or drawings in advance

Keeping the joints sound
Regular inspection catches problems early. Specifically:
- Track which buildings were done and when
- Group repairs into a planned programme
- Share your contractor requirements early
- Check sealant joints during planned building inspections
Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order and work down the list.
When something else is needed
Being straight saves everyone time. Fresh joints won’t solve:
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Leaks through the frame itself rather than the perimeter
- Leaks from above rather than through a joint
If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think.
Where we work in Great Chart

Looking after buildings in and around Great Chart
The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. At about 47 miles from central London, Great Chart is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property.
Historic properties like Godinton House (1.1 miles north of Great Chart) show the age of some local stock, where frame mastic must suit soft brick or stone. For owners of several units at places like St. Georges Business Centre, 1 mile to the north-east of Great Chart, one programme can deal with frame and external mastic across the lot. Older community buildings, Church of St Mary among them, often have frames of mixed ages whose mastic varies.
