Need mastic sealing in Eel Pie Island?

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Our process

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a few days for most blocks, with larger programmes scheduled building by building, and we clear our waste as we work. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. A fixed quote follows, split by block or building if that suits you.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Completed joints are inspected and carry a 12-month workmanship guarantee.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Point out any areas we must not close
  • Share the asbestos register for older buildings

Request a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or send details through our quote form.

Mastic sealing in Eel Pie Island, done properly

Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. The enquiries we see most involve cracked, hardened mastic round windows on a block and no planned programme for sealant, across balcony and threshold joints, communal kitchens and washrooms and window and door perimeters on blocks. A single leaking joint is often how a building in Eel Pie Island first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Across Greater London, Eel Pie Island included, the ULEZ applies, and parking and loading rules differ from street to street. For block-wide work, a place to park and store materials saves time on every visit.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Work for main contractors and building owners

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Quoting for work in Eel Pie Island

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

  • The product specified
  • Location, for remote and island sites
  • The site’s rules and procedures
  • Whether the work must be split into stages

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.

Details that help us quote

We can often quote from photographs and a few details. It helps to include:

  • What the building is and how it’s used
  • The postcode of the building
  • Any dates the work must fit around
  • Drawings or a marked-up plan, if available

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Do you need mastic sealing in Eel Pie Island?

Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Regular cleaning wears them further.

Clients usually get in touch after noticing one or more of the following:

  • Worn sealant at communal door frames
  • Brittle perimeter mastic across a building
  • Water getting in round frames after rain
  • Occupiers reporting cold air round windows

Site managers at schools like St Mary's Church of England Primary School can fit frame mastic into the summer works.

Comparing quotes

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Is the sealant right for the movement and the substrate?
  • How the joint faces will be prepared and primed
  • Their public liability cover

Our contractor checklist

How the job changes by surface

Commercial and mixed-use buildings

Commercial occupiers typically stay open during the work so the work is phased.

Window and door perimeters on blocks

We usually work through a block’s windows in a planned order. Access is agreed with you before the quote is fixed.

Questions about Eel Pie Island

Do you work for managing agents with blocks near Twickenham station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.

Do you take on jobs in Eel Pie Island where loading and access are tightly controlled?

Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you work in Eel Pie Island?

Yes. We take on work across Eel Pie Island.

Does the weather affect the work?

Outside, 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.

Do you do block-wide mastic programmes?

We can. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.

What guarantee do you give on resealing?

A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.

Aftercare for building managers

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

  • Share the asbestos register when you send details
  • Keep bins and bikes away from communal door frames
  • Include mastic in your cyclical inspections
  • Prioritise elevations facing the weather

Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.

The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.

Planned mastic for Eel Pie Island portfolios

For a London block, the agent or landlord usually handles notices to residents and access to flats. We work to your notice and access plan.
