About our mastic sealing in High Ongar
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Resealed mastic joints in High Ongar carry our 12-month guarantee. We work on communal entrances and stairwells, balcony and threshold joints and shopfronts below residential blocks, and the usual reasons a site gets in touch are movement joints with sealant missing and no planned programme for sealant. Whether you call it commercial sealant work, mastic application or joint sealing, in High Ongar it comes down to the same thing: the right product in a properly prepared joint.
In and around smaller places like High Ongar, 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.
A 12-month guarantee applies to all our work. Should something we installed fail, ring 01277 525 020 or email us and we will come back to it.

Blocks and managed buildings in High Ongar
High Ongar is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building normally need attention first. High Ongar lies roughly 21 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate.
Property owners at sites such as Hallsford Bridge Industrial Estate, 0.9 miles south of High Ongar, can have mastic renewed between lettings. Churches, halls and community buildings such as Church of St Mary the Virgin are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. If your remit includes a building such as High Ongar Primary School, frame and door mastic can be programmed for the holidays.
High Ongar is about 6 miles north of Brentwood, in Essex. Commercial clients in High Ongar use us for work on mastic joints, as part of our coverage of Essex. We work across 644 places in Essex, large and small. London is covered too, some 21 miles away.

Advice
Why it’s worth doing now in High Ongar
A bead run over old mastic can look like a repair. It doesn’t bond and usually fails within a short time. Full removal and proper preparation is what lasts. Older rural buildings around High Ongar 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.
We don’t publish prices, since every building and every scope is different. Call for a quote.

High Ongar: questions and answers
Is High Ongar off your patch?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Is Hallsford Bridge Industrial Estate, near High Ongar, within your area?
Yes. Estates, retail parks and business parks around High Ongar, Hallsford Bridge Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Do you work with property factors and landlords?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
Do you do block-wide mastic programmes?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Do you supply RAMS and insurance details?
Our credentials include CHAS, Constructionline and public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
How the job changes by surface
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.
Estate-wide resealing programmes
Consistent products and colours across an estate make future maintenance simpler.

When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Misted or failed double-glazed units
- Frames that are rotten, warped or broken
- Materials that need asbestos testing before work
Not sure which it is? You can call 01277 525 020 or email us and we will tell you honestly.
