When to call us in Norton Heath

UV and rain age external sealant. It stiffens, stops stretching and cracks, especially on south and west faces.

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

  • No planned programme for sealant
  • Occupiers reporting cold air round windows
  • Mastic failing across several blocks on an estate
  • A mix of products and colours from past repairs

Older community buildings, Church of All Saints among them, often have frames of mixed ages whose mastic varies.

Questions to ask before you book

  • The terms of the workmanship guarantee
  • What level of public liability insurance do they hold?
  • Can the work be phased to keep areas open?
  • How the joint faces will be prepared and primed

Our contractor checklist

How we handle mastic sealing in Norton Heath

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. We work on external wall and movement joints, communal entrances and stairwells and shopfronts below residential blocks, and what we’re called in for most is worn sealant at communal door frames and occupiers reporting cold air round windows. One point of contact handles commercial sealant work in Norton Heath from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Owners and agents with buildings around smaller places such as Norton Heath tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

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

Norton Heath sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first. At about 23 miles from central London, Norton Heath is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide.

Student blocks close to universities like Writtle University College Cow Watering Campus, 4.3 miles to the east of Norton Heath, are easiest to work on between tenancies. Site managers at schools like Blackmore Primary School can fit frame mastic into the summer works.

Norton Heath is about 6 miles north of Brentwood, in Essex. Commercial clients in Norton Heath use us for work on mastic joints. Norton Heath is one of 644 places we cover in Essex for mastic joints. London is covered too, around 23 miles from Norton Heath.

What the job involves on each surface

Tenement and older buildings

Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.

Planned maintenance

How long mastic lasts depends on exposure, movement and the product used. Inspecting joints regularly keeps programmes on track.

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Norton Heath: questions and answers

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

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.

Is Norton Heath too small for you to travel to?

Not at all. Norton Heath is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

How long does a job like this take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

What about access for upper-floor joints?

Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned, and we will tell you how we’d approach it.

Do you work for managing agents and housing associations?

Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.

How long before the joints can be used?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

What paperwork can you provide?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.

Diagnose, treat, sign off

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking a day or two for a single block, longer for an estate programme. Smaller jobs around Norton Heath can be grouped with others nearby. You will have a fixed quote before work starts.

Why appoint us

  • Products installed to the manufacturer’s instructions
  • A range of standard colours, depending on the product
  • Public liability insurance in place

Take a look at our cost guide or how we’re accredited.

When something else is needed

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Materials that need asbestos testing before work
  • Leaks through the frame itself rather than the perimeter
  • Masonry that has broken away beside the joint

If in doubt, ring 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

Surfaces we seal

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