How we handle mastic sealing in West Ham

Owners and agents normally inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. We work on communal entrances and stairwells, window and door perimeters on blocks and communal kitchens and washrooms, and what we’re called in for most is complaints coming in block by block and open joints in brickwork or panels. One point of contact handles commercial sealant work in West Ham from the first photographs to the final walk-round, whether it’s one building or several.

Across Greater London, West Ham included, the ULEZ applies, and parking and loading rules differ from street to street. For a block or estate, it helps to know where we can park and stage materials.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Questions we’re asked in West Ham

Can work in a care setting near West Ham go ahead while residents are there?

Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we will work to them.

Will you take on work at estates like Crescent Court Business Centre, close to West Ham?

Yes. We cover West Ham and the area around it, including industrial estates, business parks and retail parks such as Crescent Court Business Centre. A few photographs and the unit address let us price the work.

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.

Do you guarantee the mastic work?

There is a 12-month guarantee on our workmanship and we hold public liability insurance.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Do you supply RAMS and insurance details?

Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.

Mastic sealing around West Ham: points for this area

For a London block, the agent or landlord normally handles notices to residents and access to flats. We work to your notice and access plan. 18 care or nursing homes sit less than 2 miles from West Ham. Care home owners need frame and external mastic kept sound without unsettling residents.

Churches, halls and community buildings such as Church of All Saints are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Student accommodation around universities such as University of East London (to the north-west of West Ham) is usually managed block by block, which suits a planned mastic programme.

West Ham is about 2 miles west of East Ham, in Greater London. Commercial clients in West Ham use us for work on mastic joints. We work across 764 places in Greater London, large and small.

Nearby places we also cover include Upton (1 mile north-east), Greengate (1 mile south-east), Maryland (1 mile north-west), Stratford (1 mile north-west) and Plaistow (1 mile south-east) for mastic joints.

What affects the price in West Ham

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Any access equipment needed
  • The site’s rules and procedures
  • The total length or number of joints
  • Which sealant the job calls for

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Sending details for a quote

We can often quote from photos and a few details. Please tell us:

  • Specification clauses that apply
  • Whether an asbestos survey exists
  • Drawings or a marked-up plan, if available
  • Whether the building will be occupied during the work

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or use the quote form.

Looking after the joints

After handover, these steps help:

  • Avoid piecemeal callouts where you can
  • Share your contractor requirements early
  • Look at the sunniest and most exposed elevations first
  • Keep a record of when each building was resealed

Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.

Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings so spending is spread.

When to call us in West Ham

Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope and fails early.

Common reasons buildings call us in:

  • The same joint failures repeated across a portfolio
  • Communal area joints that look neglected
  • Complaints coming in block by block
  • Old repairs sealed over failed mastic

If you look after a block within reach of West Ham station (0.5 miles south-west of West Ham), frame and balcony mastic can be renewed on one programme.

Questions to ask before you book

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • What level of public liability insurance do they hold?
  • Will RAMS and insurance details be available?
  • What the guarantee covers, and for how long

Questions to ask before you appoint anyone

How the job changes by surface

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.

Tenement and older buildings

Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.

Owners, agents and contractors

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Diagnose, treat, sign off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. All of Greater London is in the ULEZ, and kerbside space in West Ham can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

Preparing the site

  • Point out any areas we must not close
  • Tell us your opening times and when work is allowed
  • Let us know about inductions and permits

Request a quote

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
