How we handle mastic sealing in Ash
Before work starts, most agents and landlords want the documents in order. 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. If you have estate-wide sealant that is simply worn out and movement joints with sealant missing, we can help. Looking for mastic applicators who cover Ash? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
For buildings around smaller places like Ash, we group work so one trip covers it. Send photos of the frames and joints and we’ll give a fixed quote.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

When to call us in Ash
UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.
Most enquiries start with something like this:
- Draughts at frames across a block
- Cracked, hardened mastic round windows on a block
- Communal area joints that look neglected
- The same joint failures repeated across a portfolio
For agents with blocks near Longfield station, 2.8 miles to the north of Ash, a block-wide mastic programme deals with frames, balconies and entrances in one go.

Questions about Ash
Do you cover business parks and estates near Ash, such as Heaver Farm Trading Estate?
Yes, sites like Heaver Farm Trading Estate are within our area, along with the rest of Ash. Photos and a short description are enough for a first look.
Is Ash too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Do you check for asbestos in old sealant?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
How do we ask for a quote?
You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
Can you take on resealing for a block portfolio?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn with dates agreed in advance.
Surface by surface
Estate-wide resealing programmes
A programme can start with the worst buildings and work down. Quotes can be per block or for the full programme.
Commercial and mixed-use buildings
Commercial occupiers typically stay open during the work so the work is phased.
For owners and agents in Ash
Ash is about 19 miles from central London. Within reach of London, blocks run by agents and associations are common around stations. Ash sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.
Historic properties like Lullingstone Castle, 4.2 miles to the west of Ash, show the age of some local stock, where frame mastic must suit soft brick or stone. Churches, halls and community buildings such as Parish Church of Saint Peter and Saint Paul are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Ash is about 6 miles south-west of Northfleet, in Kent. Any commercial site in Ash is covered, whether it’s a single job or part of a planned programme. We work across 931 places in Kent. We also cover London, some 19 miles away.
If you need mastic sealing in TN15 and DA3, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. If your site is on Ash Road, The Street and Billet Hill or close by, send details and we’ll quote for mastic joints. If your building is just outside Ash, we cover West Yoke (1 mile north), Fawkham Green (1 mile north-west), Speed Gate (1 mile north-west), Stansted (2 miles south) and West Kingsdown (2 miles south-west). Bigger towns within reach include Maidstone (12 miles south-east), Dartford (7 miles north-west), Sevenoaks (7 miles south-west), Royal Tunbridge Wells (15 miles south), Gravesend (6 miles north-east) and Tonbridge (11 miles south).
What’s near Ash
In Ash, that means premises near The White Swan Public House and the streets around them. Ash’s nearest station is Longfield station, about 2.8 miles north of the centre. Nearby you will also find Darent Valley Hospital (5.6 miles north) and Eynsford Castle (3.6 miles west).
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Group repairs into a planned programme
- Start inspections with the most exposed faces
- Make mastic part of routine maintenance checks
- Ask residents or tenants to report leaks and draughts early
Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
What affects the price in Ash
A fixed quote reflects the actual work. It takes account of:
- The total length or number of joints
- Whether old sealant has to be cut out first
- Induction, permit and paperwork requirements
- Distance, for remote addresses
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.
Details that help us quote
There’s no need for a formal survey. These details are enough to start:
- When you need the work done
- What the building is and how it’s used
- Specification clauses that apply
- Where the site is, with the postcode
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
On site: what to expect
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Ash may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

Advice
Owners, agents and contractors
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
