Mastic sealing in Notting Dale

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

Diagnose, treat, sign off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Getting the site ready

  • Arrange parking or a loading space
  • Share your working hours and any access restrictions
  • Send any specification or drawings in advance

Mastic sealing in Notting Dale, done properly

In buildings from before 2000, some old mastics contain 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. We work on external wall and movement joints, balcony and threshold joints and shopfronts below residential blocks, and the usual reasons a site gets in touch are no planned programme for sealant and a mix of products and colours from past repairs. For commercial sealant work in Notting Dale, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. We work to the agent’s notice and access plan, so residents know what’s happening.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Leave it or put it right?

Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.

A quote for mastic joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Why clients in Notting Dale choose us

  • Matching to RAL references, product permitting
  • Clear, fixed quotes
  • One phone line for London, the South East and Scotland
  • Failed material removed, not covered up

Read our cost guide and how we’re accredited.

Aftercare for building managers

Regular inspection catches problems early. Specifically:

  • Keep a record of when each building was resealed
  • Protect low-level joints in entrances
  • Ask residents or tenants to report leaks and draughts early
  • Mention RAMS, insurance or CSCS requirements up front

Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.

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

What we can’t put right

We check first that sealant really is the fix. It isn’t the answer for:

  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Asbestos-containing sealant, which we don’t remove
  • Broken glass or failed sealed units

Not sure which it is? You can call 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

What we seal

  • External wall and movement joints
  • Communal entrances and stairwells
  • Shopfronts below residential blocks
  • Balcony and threshold joints
  • Communal kitchens and washrooms
  • Window and door perimeters on blocks

Common questions from Notting Dale clients

Do you work in London buildings with loading restrictions?

Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for

Is Stable Way Industrial Estate, near Notting Dale, within your area?

Yes. Estates, retail parks and business parks around Notting Dale, Stable Way Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

What guarantee do you give on resealing?

Our workmanship carries a 12-month guarantee, backed by public liability insurance.

Is asbestos a concern with old mastic?

Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.

How do you handle work on occupied blocks?

The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Mastic sealing around Notting Dale: points for this area

London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We fit the programme to your notice periods.

For a school such as Thomas Jones Primary School, perimeter mastic on windows and doors is a holiday job. If you own or manage units on a site such as Stable Way Industrial Estate, 0.5 miles to the west of Notting Dale, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Blocks of flats and mixed-use buildings often cluster around stations such as Shepherds Bush station (to the south-west of Notting Dale) and their window and balcony mastic tends to age at the same rate across a building.

What affects the price in Notting Dale

Before we quote, we look at:

  • Which sealant the job calls for
  • Access and working height
  • Backing rod, priming and other preparation
  • Distance, for remote addresses

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Sending details for a quote

To price the job accurately, we need to understand the site. Useful things to include:

  • Rough lengths or quantities, or drawings if you have them
  • Specification clauses that apply
  • Whether the building will be occupied during the work
  • When you need the work done

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, phone 01277 525 020 or email us.

General trades versus a specialist

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
