Facade sealing in Farringdon
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
How the quote is worked out
Each job is priced on its own details. The things that drive the figure:
- How much there is to seal
- Access and working height
- Location, for remote and island sites
- How much existing material needs removing
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Sending details for a quote
A few photographs plus some basic facts will normally do. It helps to include:
- A wide shot and a close-up of the area
- Asbestos survey details if the building is older
- Drawings or a marked-up plan, if available
- Access details, including height
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
Facade sealing in Farringdon, done properly
External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. We work on perimeter joints where frames meet the structure, cladding panel joints and coping and flashing joints, and what we are called in for most is gaps between rainscreen or cladding panels and facade joints cracked through the middle. A single leaking joint is often how a building in Farringdon first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Farringdon, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Every job we finish is backed by a 12-month workmanship guarantee, in Farringdon as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

New build and refits around Farringdon
The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. At about 47 miles from central London, Farringdon is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.
For contractors refurbishing units at places like Farringdon Industrial Centre, which lies west of Farringdon, the mastic covers cladding panels, roller-door and window perimeters. Historic houses such as Bentworth Hall (3.7 miles north-west of Farringdon) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Will you quote for a small job?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Should we check old sealant for asbestos?
For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder, so ask for it before we start. If asbestos is suspected, work stops until it is tested.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or use the quote form. Include photos or drawings if you have them.
Is it okay to overlay old mastic?
No. Overlaying is a shortcut that peels away quickly. We remove the failed sealant, clean the faces, set the depth and reseal.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
How the job changes by surface
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod, primed where the maker specifies.
Perimeter joints at frames and structure
Perimeter joints at frames often show their age first. They are cut out, cleaned, backed and resealed using a sealant classified for that use.
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Clear debris that holds water against joints
- Walk the elevations once or twice a year
- Keep pressure washers away from fresh sealant
- Check the asbestos register before old mastic is disturbed
Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade.
Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones.

What we are called out for in Farringdon
Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly.
These are often picked up first by site or facilities staff:
- Hard, chalky sealant that no longer flexes
- Leaks at window and door perimeters
- Facade joints cracked through the middle
- Perimeter joints where frames meet the structure
For a contractor working at a hospital such as Alton Community Hospital, 2 miles north of Farringdon, perimeter and facade sealing is planned around patients and deliveries.
