Facade sealing in Eden Park

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

Facade sealing in Eden Park, done properly

We don’t install glazing systems or replace glass. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters. The enquiries we see most involve sealant pulling away from frames or panels and cold air coming in at window perimeters, across coping and flashing joints, cladding panel joints and perimeter joints where frames meet the structure. Looking for mastic applicators who cover Eden Park? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Around Eden Park, 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.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Should maintenance staff do it?

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

For managing agents and facilities managers

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

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.

Eden Park: questions and answers

Can you work around term dates at a campus such as Shaftesbury Nash College?

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.

Does your area include sites such as Chaffinch Business Park, near Eden Park?

Yes. Our area takes in Eden Park and its surroundings, with estates and business parks such as Chaffinch Business Park included. Send details of the unit and the work through our quote form for a quick quote.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Can you find out why a window is leaking?

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

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Can you work in cold or wet weather?

Rain and frost can pause external sealing. The programme allows for it and we tell you if the forecast changes things throughout the job.

Honest limits

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Installing or repairing glazing systems
  • Water getting in through cracked render or porous masonry
  • Render or concrete edges that have broken away

If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

What we seal

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

New build and refits around Eden Park

The area within 2 miles of Eden Park holds several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. As part of Greater London, Eden Park is inside the ULEZ, which applies to every van on site. Deliveries are booked and storage is tight, so mastic materials come in as needed.

For contractors at a school such as Langley Park School for Boys, sealing has to be finished before term starts. For a contractor working at a hospital such as Bethlem Royal Hospital (0.5 miles south-west of Eden Park), perimeter and facade sealing is planned around patients and deliveries.

Eden Park is about 1 mile south of Beckenham, in Greater London. We send applicators to Eden Park for facade joints. Eden Park is one of 764 places we cover in Greater London for facade joints. Our London page has more on work in that area (8 miles or so).

Commercial sites across BR3, BR4 and CR0 are covered. Among the streets we cover are Whitstone Lane, Brockwell Avenue and St Martin's Lane. Sites close to Eden Park are covered too, including West Wickham (1 mile south), Spring Park (1 mile south), Coney Hall (1 mile south), Elmers End (1 mile north-west) and Monks Orchard (1 mile west). A short drive away, we cover London (8 miles north), City of Westminster (10 miles north-west), Marylebone (10 miles north-west), Kensington (11 miles north-west), St Pancras (10 miles north-west) and Shoreditch (10 miles north).

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking anything from a single day to several weeks, depending on joint lengths, access and the weather. 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. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and both faces cleaned back.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

What we need from you

  • Warn occupants and staff about the work
  • Clear stock, furniture or equipment away from the joints
  • Point out any areas we must not close

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

What the job involves on each surface

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone, with primer where its maker specifies.

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.

What we are called out for in Eden Park

When the sealant tears down its centre, it has normally been asked to move more than it can. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

It’s worth sending us details if you spot any of the following:

  • New sealant peeling off old mastic
  • Cladding panel joints that have opened up
  • Discoloured or dirty facade joints
  • Damp patches beside frames after rain

Older buildings in the area around Eden Park, such as Bromley Palace, which lies north-east of Eden Park, need care when sealed: the product has to suit soft or historic materials.

Questions to ask before you book

  • Will failed sealant be removed rather than covered?
  • How they handle RAMS and site documents
  • Can the work be phased to keep areas open?
  • Will CSCS-carded applicators be on site?
