Mastic sealing in Five Ashes
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. Most enquiries involve damp patches beside frames and brittle perimeter mastic across a building, on communal kitchens and washrooms, shopfronts below residential blocks and communal entrances and stairwells. Searching for sealant specialists in Five Ashes? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Around smaller places like Five Ashes, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Aftercare for building managers
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Make mastic part of routine maintenance checks
- Track which buildings were done and when
- Check the asbestos register before any old mastic is disturbed
- Reduce knocks to communal area joints
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first.
Cost factors for mastic joints
These are the things that shape the price:
- Distance, for remote addresses
- Quantities, in metres or numbers
- The site’s rules and procedures
- Backing rod, priming and other preparation
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
What to include in your enquiry
To price the job accurately, we need a clear picture of the site. Send us:
- When you need the work done
- The asbestos register, for older buildings
- Clear photos of the problem areas
- Access details, including height
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or send details through our quote form with what you know.
Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
Common questions from Five Ashes clients
Will you take on work at estates like Station Road Industrial Estate, close to Five Ashes?
Yes. Estates, retail parks and business parks around Five Ashes, Station Road Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Is a smaller place like Five Ashes outside your area?
No. Places such as Five Ashes are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
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.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Can you quote from photos?
It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
Do you need mastic sealing in Five Ashes?
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
If one of these sounds familiar, it’s time for a closer look:
- Leaks at window and door perimeters
- Window mastic that has split and shrunk
- No planned programme for sealant
- Patchy repairs in mismatched sealant
If you look after a block within reach of Crowborough station, which lies north-west of Five Ashes, frame and balcony mastic can be renewed on one programme.

On site: what to expect
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by.

When to bring in a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
For owners and agents in Five Ashes
Five Ashes sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Central London is about 37 miles from Five Ashes. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate.
Landlords with units on estates such as Station Road Industrial Estate, 2.7 miles south-east of Five Ashes, can bring frame, door and external mastic across several units into one programme. If you are responsible for a building such as Church of the Good Shepherd, frame and door mastic needs the same attention as any other property.
