Facade sealing in Lower Farringdon

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Facade sealing in Lower Farringdon, done properly

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds. Most enquiries involve air leaks through failed facade joints and leaks at window and door perimeters, across stone and brick facade joints, shopfront frames and cladding panel joints. For commercial sealant work in Lower Farringdon, you deal with one contact from quote to sign-off, whether it’s one building or several.

For a site near Lower Farringdon, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photos and the programme and we’ll quote to suit.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What happens if it’s left?

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Leaks travel along the structure, often turning up far from the joint. Older rural buildings around Lower Farringdon 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.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why appoint us

Surface by surface

Cladding panel joints

On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end.

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.

Facade sealing around Lower Farringdon: points for this area

Lower Farringdon is in the South East, one of the UK’s drier regions. 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. Lower Farringdon lies roughly 47 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.

New wings at hospitals like Alton Community Hospital, 2 miles north of Lower Farringdon, bring long runs of window and panel joints to seal. With historic properties like Bentworth Hall, 3.5 miles north-west of Lower Farringdon, in the area, refurbishment work often meets old masonry that needs compatible sealants. For contractors refurbishing units at places like Farringdon Business Park, less than half a mile west of Lower Farringdon, the mastic covers cladding panels, roller-door and window perimeters.

Lower Farringdon is about 3 miles south of Alton, in Hampshire. We cover Lower Farringdon, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 723 places across Hampshire fall within our area, Lower Farringdon among them. We also cover Portsmouth, some 21 miles away.

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Building owners and managing agents use us on everything from one building to a spread of sites around Lower Farringdon. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Diagnose, treat, sign off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. For work around Lower Farringdon, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Getting the site ready

  • Warn occupants and staff about the work
  • Confirm the product named in the specification
  • Share the asbestos register for older buildings

Getting a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Joints whose design needs changing by the specifier
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Specialist high-level access methods

If in doubt, speak to us on 01277 525 020 or email us and we’ll say what we think.

Surfaces we seal

  • Cladding panel joints
  • Coping and flashing joints
  • Stone and brick facade joints
  • Perimeter joints where frames meet the structure
  • Window and door perimeters
  • Shopfront frames

Maintenance after handover

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Walk the elevations once or twice a year
  • Note when each elevation was last resealed
  • Insist on a full cut-out when joints are renewed
  • Check the asbestos register before old mastic is disturbed

Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.

Coordinate facade sealing with other external works. One set-up for several trades saves money and limits disruption.

Questions we are asked in Lower Farringdon

Can you work at a site such as Farringdon Business Park, by Lower Farringdon?

Yes. Estates, retail parks and business parks around Lower Farringdon, Farringdon Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Is Lower Farringdon too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

How soon can the area be used again?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Can you find out why a window is leaking?

Yes. Photos help, and you can call the office on 01277 525 020 or email a schedule or drawings to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we’ll tell you which.

Can you work in cold or wet weather?

Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things throughout the job.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
