Facade sealing in Foots Cray

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

On site: what to expect

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • Share the asbestos register for older buildings
  • Send your site hours and access windows
  • Clear stock, furniture or equipment away from the joints

Facade sealing in Foots Cray, done properly

Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around. We work on perimeter joints where frames meet the structure, cladding panel joints and coping and flashing joints, and the usual reasons a site gets in touch are failed seals around shopfront and entrance frames and sealant pulling away from frames or panels. Most enquiries from Foots Cray start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around Foots Cray, as across London, much of the work is refurbishing existing buildings as well as building new ones. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Mastic packages on Foots Cray sites

A 2-mile radius around Foots Cray takes in several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. The ULEZ covers the whole of Greater London, Foots Cray included, so site vehicles need to meet its standards or pay the daily charge. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.

Units on estates such as Crayfields Business Park (0.6 miles south of Foots Cray) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. For contractors on a campus like University of Greenwich Avery Hill Campus, 2.6 miles north-west of Foots Cray, facade and perimeter sealing has to fit around students and term dates.

Foots Cray is about 1 mile south-east of Sidcup, in Greater London. Anywhere in DA14, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Greater London coverage takes in 764 places. Sites around London have their own page, about 11 miles away.

We cover the DA14 and BR5 postcode districts for facade joints. If your site is on Cray Road, Evry Road and The Avenue or close by, we can quote for facade joints. Main routes into Foots Cray include the A223, useful when we plan access and materials. Just outside Foots Cray, we also work in Ruxley (1 mile east), Albany Park (1 mile north-west), Upper Ruxley (1 mile east), Sidcup (1 mile north-west) and North Cray (2 miles north-east). Bigger towns within reach include London (11 miles north-west), City of Westminster (13 miles north-west), Marylebone (13 miles north-west), Kensington (15 miles north-west), St Pancras (13 miles north-west) and Shoreditch (11 miles north-west).

What sets the cost

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Location, for remote and island sites
  • How much there is to seal
  • Backing rod, priming and other preparation
  • Working within restricted access windows

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Send us:

  • Drawings or a marked-up plan, if available
  • The type of building and who uses it
  • The postcode of the building
  • Photos of the joints, close up and from further back

To get a fixed quote, ring 01277 525 020 or email a schedule or drawings with the site address and an outline of the work. You can also send details through our quote form.

General trades versus a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Do you need facade sealing in Foots Cray?

When sealant lets go of a frame or panel, the cause is often the preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and the joint opens with the first real movement.

These are often picked up first by site or facilities staff:

  • Weathered facade joints that have lost their grip
  • Cladding panel joints that have opened up
  • Draughts around frames and panels
  • Damp patches beside frames after rain

New wings at hospitals like Queen Mary's Hospital (0.5 miles west of Foots Cray) bring long runs of window and panel joints to seal.

What your quote should include

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • The named product and why it was chosen
  • How the existing material will be dealt with
  • How they handle RAMS and site documents

Choosing a commercial sealant contractor

Why act early in Foots Cray

Failed joints let in more than water: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

  • Movement beyond what any sealant can handle
  • Specialist high-level access methods
  • Installing or repairing glazing systems

If you are not sure, just phone 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

FAQs: Foots Cray

Do you take on work at healthcare sites like Queen Mary's Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will you plan work around the academic year at somewhere like University of Greenwich Avery Hill Campus?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is the work guaranteed?

Yes. Our workmanship is backed for 12 months.

What will the job cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Can you just add new sealant on top?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the joint cleaned back to sound material. That is what makes the new joint last.
