About our facade sealing in Upper Farringdon

From enquiry to sign-off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. Smaller jobs around Upper Farringdon can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and both faces cleaned back.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Agree which areas must stay open
  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000

Advice

For managing agents and facilities managers

We work for building owners and managing agents on everything from one building to a spread of sites around Upper Farringdon. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Why act early in Upper Farringdon

Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer. Converted and older buildings near places like Upper Farringdon tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Building and refurbishing in Upper Farringdon

Rainfall across the South East, Upper Farringdon included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager. Upper Farringdon is about 47 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.

New wings at hospitals like Alton Community Hospital, 2 miles to the north of Upper Farringdon, bring long runs of window and panel joints to seal. When units on a site such as Farringdon Industrial Centre, 0.7 miles to the west of Upper Farringdon, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Note when each elevation was last resealed
  • Add perimeter sealant to planned maintenance checks
  • Check the asbestos register before old mastic is disturbed
  • Check that rainwater leaves the facade the way it was designed to

Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed rather than sitting against the joints.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

Do you need facade sealing in Upper Farringdon?

The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.

Typical triggers for a call:

  • Damp patches beside frames after rain
  • Cladding panel joints that have opened up
  • Facade joints cracked through the middle
  • Previous reseals run over old sealant

With historic properties like Bentworth Hall (3.9 miles north-west of Upper Farringdon) in the area, refurbishment work often meets old masonry that needs compatible sealants.

Questions to ask before you book

  • Is the sealant right for the movement and the substrate?
  • Who will actually carry out the work
  • How they’ll work around occupants
  • How the joint faces will be prepared and primed

Quoting for work in Upper Farringdon

Your fixed quote is built from the real scope. It allows for:

  • The product specified
  • Access and working height
  • How much there is to seal
  • Location, for remote and island sites

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What to include in your enquiry

However big the job, these details speed things up:

  • Anything awkward about access or site hours
  • Whether an asbestos survey exists
  • Photos of the joints, close up and from further back
  • The product your specification calls for

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Common questions from Upper Farringdon clients

Is Upper Farringdon too far out for you?

No. Places such as Upper Farringdon are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Is hospital work, at somewhere like Alton Community Hospital, something you do?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Can you find out why a window is leaking?

Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one, and we will be honest about which it is.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Are you fully insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Does weather matter for sealant work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
