About our mastic sealing in Upper Farringdon
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. Most enquiries involve mastic failing across several blocks on an estate and draughts at frames across a block, on communal kitchens and washrooms, shopfronts below residential blocks and external wall and movement joints. A single leaking joint is often how a building in Upper Farringdon first comes to us: we look at the rest while we are there and tell you what we find.
For owners with a single building near Upper Farringdon, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Mastic sealing around Upper Farringdon: what changes locally
Upper Farringdon 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. Upper Farringdon is about 47 miles from central London. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide.
If you look after a block within reach of Alton station (2.8 miles north of Upper Farringdon), frame and balcony mastic can be renewed on one programme. Older buildings near Upper Farringdon, from historic houses such as Bentworth Hall, 3.9 miles to the north-west of Upper Farringdon, to more modest stock, need compatible products when frames are resealed.
Upper Farringdon is about 3 miles south of Alton, in Hampshire. If you’re looking for mastic sealing in Upper Farringdon, we can help, as we do across Hampshire. Upper Farringdon is one of 723 places we cover in Hampshire. Portsmouth is covered too, some 21 miles away.

Questions we’re asked in Upper Farringdon
Will you take on a block within reach of Alton station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
Is Farringdon Industrial Centre, near Upper Farringdon, within your area?
Yes. We cover Upper Farringdon and the area around it, including industrial estates, business parks and retail parks such as Farringdon Industrial Centre. A few photos and the unit address let us price the work.
Do you do block-wide mastic programmes?
Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
How long does a typical visit take?
It depends on the scope, though a typical visit typically takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.
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.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
How a job runs
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. Rural sites near Upper Farringdon may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We check the asbestos register for older buildings and look at the joints.
- The products and programme are set out in a fixed quote.

Getting a fixed quote

Building owners, agents and FMs in Upper Farringdon
We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Leave it or put it right?
Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go, under a single quote and a single programme. One visit to deal with every failing joint makes more sense than several trips to a place like Upper Farringdon, rather than one at a time. Photos of every joint help us quote for the whole job.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

What else we do in Upper Farringdon
Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Mention RAMS, insurance or CSCS requirements up front
- Encourage occupiers to report problems at frames
- Check the asbestos register before any old mastic is disturbed
- Make mastic part of routine maintenance checks
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing.
When to call us in Upper Farringdon
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Cleaning products add to the wear.
Site and facilities staff are often the first to spot these:
- Draughts at frames across a block
- Complaints coming in block by block
- Damaged joints in communal entrances and corridors
- Patchy repairs in mismatched sealant
If you own or manage units on a site such as Farringdon Industrial Centre, which lies west of Upper Farringdon, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
