Mastic sealing for commercial buildings in Heath Park

Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Entrances and stairwells are kept in use throughout. If you have communal area joints that look neglected and movement joints with sealant missing, we can help, on shopfronts below residential blocks, balcony and threshold joints and communal entrances and stairwells alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Heath Park, that means joint design, primers and backing rod as standard.

Across Greater London, Heath Park 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.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

On site: what to expect

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. Dates and areas are agreed so occupiers can be told.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Share the asbestos register for older buildings
  • Explain the parking and delivery arrangements

What the job involves on each surface

External movement joints

Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.

Estate-wide resealing programmes

Housing associations and agents often manage many similar blocks. We quote building by building and work through them in turn.

Mastic sealing around Heath Park: how the place shapes the job

Blocks in London are normally run by managing agents, landlords or housing associations, with residents to notify and access to arrange. We plan around the notices and access you arrange.

Blocks of flats and mixed-use buildings often cluster around stations such as Gidea Park station (0.5 miles north of Heath Park) and their window and balcony mastic tends to age at the same rate across a building. Schools and community buildings such as Squirrels Heath Infant School need frame and external mastic kept sound like any building.

Cost factors for mastic joints

These are the things that shape the price:

  • The product specified
  • Removal of failed or old sealant
  • How accessible the joints are
  • Joint width, depth and condition

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Sending details for a quote

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • When you need the work done
  • The postcode of the building
  • Anything awkward about access or site hours
  • The asbestos register, for older buildings

Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, call 01277 525 020 or email the details over.

When to bring in a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Common problems we fix in Heath Park

Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. We will tell you if the joint edges need repairing before resealing.

What tends to prompt an enquiry:

  • Mastic failing across several blocks on an estate
  • Window mastic that has split and shrunk
  • Communal area joints that look neglected
  • Water getting in round frames after rain

If you’re responsible for a building such as Saint Alban Church of England, frame and door mastic needs the same attention as any other property.

Questions to ask before you book

  • What site paperwork they can supply
  • Health and safety accreditation such as CHAS
  • Will failed sealant be removed rather than covered?
  • What level of public liability insurance do they hold?

Choosing a commercial sealant contractor

Why deal with it now?

Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. In Heath Park, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
