Building and refurbishing in Eel Pie Island

Site traffic in Eel Pie Island falls within London’s ULEZ, like everywhere else in Greater London. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. There are a good number of hotels within about 2 miles of Eel Pie Island. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

Further education sites such as Richmond-upon-Thames College, 0.9 miles north-west of Eel Pie Island, are extended and refurbished from time to time, with mastic often programmed into the summer break. Hotels like Alexander Pope Hotel (to the south-west of Eel Pie Island) rarely close for long, so refurbishment mastic is phased floor by floor.

Eel Pie Island is about 1 mile east of Twickenham, in Greater London. Businesses, contractors and managing agents in Eel Pie Island use us for work on facade joints. Our Greater London coverage takes in 764 places, from busy centres to rural villages. We also cover London, some 11 miles away.

Facade sealing for commercial buildings in Eel Pie Island

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits. We build that into the programme and tell you if the forecast changes the plan. The enquiries we see most involve discoloured or dirty facade joints and cladding panel joints that have opened up, across coping and flashing joints, stone and brick facade joints and shopfront frames. Most enquiries from Eel Pie Island start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Construction in a London area such as Eel Pie Island means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. Mastic is normally one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or email a schedule or drawings and we will come back to it.

What sets the cost

The price varies from site to site. Expect it to depend on:

  • How much existing material needs removing
  • Induction, permit and paperwork requirements
  • The product specified
  • Access and working height

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What to include in your enquiry

A good diagnosis starts with the right details. Tell us:

  • Anything awkward about access or site hours
  • Whether the building will be occupied during the work
  • The asbestos register, for older buildings
  • The product your specification calls for

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, ring 01277 525 020 or send details through our quote form.

Signs you need facade sealing in Eel Pie Island

Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building, and cracks or adhesion loss follow.

Any of the following is a good reason to get the joints checked over:

  • Sealant pulling away from frames or panels
  • Cold air coming in at window perimeters
  • Hard, chalky sealant that no longer flexes
  • New sealant peeling off old mastic

Recladding or extending a unit at a site like Newmans Shipyard & Business Park (0.5 miles south-west of Eel Pie Island) brings panel joints and frame perimeters into the programme.

Before you book anyone

  • Whether old or failed sealant will be cut out, not overlaid
  • Whether primer will be used where the manufacturer specifies it
  • The terms of the workmanship guarantee
  • What level of public liability insurance do they hold?

Questions to ask before you appoint anyone

When it isn’t the sealant

Some faults sit outside our scope, and we say so rather than covering them up:

  • Work on the window or framing system itself
  • Arranging specialist high-level access, which is planned with the client
  • Render or concrete edges that have broken away

If you’re not sure, just call 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

Surfaces we seal

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

Different surfaces, different methods

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and areas needing repair are flagged.

Precast concrete panels

Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod.

FAQs: Eel Pie Island

Do you take on work at healthcare sites like Cassel Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Could you schedule work at a campus like St Mary's University for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can the sealant be colour-matched?

That depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Can you quote from photographs?

That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.

What type of sealant goes on window perimeters?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Planning a London job such as one in Eel Pie Island starts with access. Give us the hours we can be on site and we’ll schedule to suit.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Confirm the product named in the specification
  • Let building users know which areas are affected
  • Tell us your opening times and when work is allowed
