How we handle mastic sealing in Farringdon
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. The enquiries we see most involve draught complaints from residents or tenants and brittle perimeter mastic across a building, on communal kitchens and washrooms, external wall and movement joints and balcony and threshold joints. Looking for mastic applicators who cover Farringdon? We’ve been sealing commercial buildings since 2005.
Owners and agents with buildings around smaller places such as Farringdon tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Your questions answered
Is Farringdon too far out for you?
Not at all. Farringdon is within our area. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Do you work for managing agents with blocks near Alton station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.
Can you reseal a whole block or estate?
Yes. We survey and price each building, then work through them in order starting wherever is most urgent.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.
Can people stay in the building while you reseal?
The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.
Can you seal joints high up on a block?
Every block is different. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
What we’re called out for in Farringdon
UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear most of all on the sunniest and most exposed elevations.
It’s worth sending us details if you spot any of the following:
- Complaints coming in block by block
- Damaged joints in communal entrances and corridors
- Estate-wide sealant that is simply worn out
- Damp patches beside frames
For owners of several units at places like Farringdon Industrial Centre, under half a mile west of Farringdon, one programme can deal with frame and external mastic across the lot.
What to look for in a quote

- How the joint faces will be prepared and primed
- How they handle RAMS and site documents

What sets the cost
We price every job individually. The main factors are:
- Backing rod, priming and other preparation
- Removal of failed or old sealant
- Site requirements such as inductions and permits
- Distance, for remote addresses
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
What we need to price the job
Whether it’s one area or a whole building, the same details help:
- The postcode of the building
- Whether an asbestos survey exists
- The type of building and who uses it
- Access details, including height
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or send photos by email.
When to bring in a specialist
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
How the job changes by surface
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. We work across portfolios on a planned basis.
Window and door perimeters on blocks
Perimeter joints on blocks are best done elevation by elevation or block by block. Access is agreed with you before the quote is fixed.
Block-wide mastic in Farringdon
Farringdon lies roughly 47 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations. Farringdon sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.
With historic buildings such as Bentworth Hall (to the north-west of Farringdon) in the wider area, owners of older properties around Farringdon should expect mastic to need a product that suits old masonry. If you are responsible for a building such as Church of All Saints, frame and door mastic needs the same attention as any other property.
Farringdon is about 3 miles south of Alton, in Hampshire. Across the GU34 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 723 places in Hampshire, large and small. Portsmouth is covered too, around 21 miles from Farringdon.
