How we handle mastic sealing in Dartford
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. Most enquiries involve cracked, hardened mastic round windows on a block and failed external movement joints, on communal entrances and stairwells, communal kitchens and washrooms and external wall and movement joints. Most enquiries from Dartford start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In a town such as Dartford, buildings managed by agents and landlords range from flats over shops to small blocks and offices. Mastic around frames, external joints and communal doors ages and needs renewing.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.
FAQs: Dartford
Does your area include sites such as Matrix Business Park, near Dartford?
Yes, sites like Matrix Business Park are within our area, along with the rest of Dartford. Photos and a short description are enough for a first look.
We manage a building near Dartford station. Can you help?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
How do you handle work on occupied blocks?
Occupiers stay in the building throughout. If any flats or units need access, we’ll tell you in advance so you can arrange it with occupiers.
Do you do block-wide mastic programmes?
Yes. We survey and price each building, then work through them in order starting wherever is most urgent.
What the job involves on each surface
Tenement and older buildings

Planned mastic for Dartford portfolios
The 2 miles around Dartford include three care or nursing homes. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
If you look after a block within reach of Dartford station (less than half a mile north-west of Dartford), frame and balcony mastic can be renewed on one programme. For a school such as Dartford Primary Academy, perimeter mastic on windows and doors is a holiday job.

What we are called out for in Dartford
Many failed joints were sealed without backing rod so the mastic is bonded on three sides. It can’t stretch properly and it tears.
Clients normally get in touch after noticing something like this:
- Estate-wide sealant that is simply worn out
- Draught complaints from residents or tenants
- Complaints coming in block by block
- A mix of products and colours from past repairs
Owners of student blocks near University of Greenwich (to the east of Dartford) can schedule frame and external mastic for the summer vacation.
What to look for in a quote
- Their plan for phasing and protecting the area
- Will RAMS and insurance details be available?
- Their pre-qualification and accreditations
- Proof of insurance
How the quote is worked out
These are the things that shape the price:
- Site requirements such as inductions and permits
- Specialist products, such as fire-rated or hygienic sealants
- Whether the work must be split into stages
- Any access equipment needed
Pricing mastic joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.
Details that help us quote
A few photos plus some basic facts will normally do. Please tell us:
- Photos of the joints, close up and from further back
- The site address and postcode
- When you need the work done
- Asbestos survey details if the building is older
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or email the details over if you’d rather talk the job through.
Maintenance after handover
A few simple habits keep the new joints working:
- Make mastic part of routine maintenance checks
- Plan resealing building by building rather than complaint by complaint
- Log resealing dates block by block
- Protect low-level joints in entrances
If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, regular inspection keeps the programme on track.
One failed perimeter usually means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
