Construction mastic near Nazeing

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Different surfaces, different methods

External facade and movement joints

Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.

Internal decorators’ caulk

Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s paintable and suits gaps that don’t move.

About our construction mastic in Nazeing

Getting a subcontractor through site induction should be simple. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we’re fully insured. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. Most enquiries involve a long mastic snag list close to completion and frame gaps too wide for sealant alone, on window and door perimeters, brick and block movement joints and cladding and panel joints. Whoever orders the work in Nazeing, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

For a site near Nazeing, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Construction mastic in Nazeing: the local picture

Nazeing lies roughly 18 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand. Nazeing sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

For contractors at a school such as Water Lane Primary Academy, sealing has to be finished before term starts. For a contractor working at a hospital such as Princess Alexandra Hospital, 2.7 miles north-east of Nazeing, perimeter and facade sealing is planned around patients and deliveries.

Nazeing is about 3 miles east of Hoddesdon, in Essex. Commercial clients in Nazeing can call on us for mastic packages. 644 places across Essex fall within our area, including Nazeing. There’s a separate page for London, roughly 18 miles from Nazeing.

We also cover Broadley Common (1 mile north-east), Roydon Hamlet (1 mile north-west), Tylerscross (1 mile north-east), Bumble's Green (1 mile south) and Halls Green (1 mile north) for mastic packages. Further afield, our area takes in Harlow (4 miles north-east), Brentwood (14 miles south-east), Loughton (6 miles south), Waltham Abbey (4 miles south), Epping (4 miles south-east) and Stansted Mountfitchet (13 miles north-east).

What we are called out for in Nazeing

Value-engineered products sometimes end up in the wrong joints. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.

Common reasons buildings call us in:

  • Snag items on joints that need redoing before handover
  • Window and door perimeters that won’t pass inspection
  • Oversized or tapered gaps around new frames
  • Cracks opening in caulked internal joints

When units on a site such as Hilgrove Business Park (1.9 miles west of Nazeing) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

What your quote should include

  • How they handle RAMS and site documents
  • Is the sealant right for the movement and the substrate?
  • Will failed sealant be removed rather than covered?
  • Health and safety accreditation such as CHAS

How to choose a sealant contractor

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
  • Faulty frames rather than failed sealant
  • Specifying the product where the designer hasn’t

Not sure which it is? You can speak to us on 01277 525 020 or email us and we will tell you honestly before you book.

Where we work in Nazeing

  • Sanitary and kitchen joints
  • Brick and block movement joints
  • Internal decorators’ caulk
  • Cladding and panel joints
  • Floor and skirting junctions
  • Window and door perimeters

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Cost factors for mastic packages

To price the job, we consider:

  • How much existing material needs removing
  • Any access equipment needed
  • Joint width, depth and condition
  • The site’s rules and procedures

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

What to include in your enquiry

A few photos plus some basic facts will normally do. It helps to include:

  • Clear photographs of the problem areas
  • Where the site is, with the postcode
  • Any dates the work must fit around
  • The product your specification calls for

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or send details through our quote form.
