Construction mastic in Loughton

Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We work on cladding and panel joints, internal decorators’ caulk and floor and skirting junctions, and what we are called in for most is different trades sealing to different standards and sealant knocked or painted over by other trades. A specialist sealant contractor works differently from a general builder: in Loughton, that means joint design, primers and backing rod as standard.

Construction in a town such as Loughton is often smaller schemes: a few new flats, a school extension, a refurbished unit. The perimeter and facade joints on a small scheme need the same sizing and preparation as on a big one.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Keeping the joints sound

Regular inspection catches problems early. Specifically:

  • Note which sealant went where at handover
  • Get the mastic subcontractor involved early in the programme
  • Keep finished joints away from paint, plaster and scrapers
  • Ask installers to correct oversized gaps first

The package carries our 12-month guarantee for workmanship. Damage by others isn’t a workmanship fault.

External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks.

Questions we’re asked in Loughton

Does your area include sites such as Oakwood Hill Industrial Estate, near Loughton?

Yes. We cover Loughton and the area around it, including industrial estates, business parks and retail parks such as Oakwood Hill Industrial Estate. To start, just give us a call on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Will you plan work around the academic year at somewhere like New City College?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.

Is the mastic package guaranteed?

Each package is backed by a 12-month guarantee. We’re also fully insured for public liability.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Why deal with it now?

Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. If the frame is in good order, cutting out and resealing the perimeter can be all it needs, which is a much smaller cost. We’ll say so if a frame itself is the problem. In Loughton, as anywhere, the simplest time to fix a failed joint is before it leaks. Once water gets in, there’s drying out and making good as well.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why appoint us

  • Fully insured
  • Coloured sealants to suit the setting, where available
  • Our applicators hold CSCS cards
  • A Constructionline member, so easy to vet

Sites and facades in and around Loughton

Loughton is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. Central London is about 12 miles from Loughton. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.

Recladding or extending a unit at a site like Oakwood Hill Industrial Estate, 0.6 miles south-east of Loughton, brings panel joints and frame perimeters into the programme. New wings at hospitals like The Holly Private Hospital, 2.2 miles south-west of Loughton, bring long runs of window and panel joints to seal. For contractors at a school such as The Alderton Infant School, sealing has to be finished before term starts.

Loughton is about 9 miles south of Harlow, in Essex. Across the IG10 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Loughton is one of 644 places in Essex on our list for mastic packages. London is covered too, around 12 miles from Loughton.

We take on mastic packages across the IG10 and IG9 postcode area, for business premises of every kind. Streets here include The Square, Station Road and Old Station Road. Access to Loughton is via the A121 and A1168. We also cover Debden (1 mile east), Debden Green (1 mile north-east), High Beech (2 miles north-west), Buckhurst Hill (2 miles south-west) and Waltham Forest (2 miles south-west). Further afield, our area takes in Harlow (9 miles north), Brentwood (10 miles east), Billericay (15 miles east), Waltham Abbey (4 miles north-west), Epping (4 miles north-east) and Newhall (9 miles north).

What’s near Loughton

How the quote is worked out

Before we quote, we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • How much existing material needs removing
  • How much there is to seal
  • The site’s rules and procedures

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Whether the building will be occupied during the work
  • How the joints are reached, and at what height
  • Whether an asbestos survey exists
  • Drawings or a marked-up plan, if available

To get a fixed quote, ring 01277 525 020 or email drawings and photos. You can also send details through our quote form.

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a town like Loughton, we try to group jobs for the same client into one visit, with one quote covering them. Give us your access times and we will fit the work in.

  1. First we take quantities off the drawings and read through the specification.
  2. We return a fixed quote that ties the mastic package to your programme.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. We seal each plot or floor as it’s released to us.
  5. Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
  6. Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

Getting the site ready

  • Confirm the product named in the specification
  • Flag any permit to work we will need
  • Agree which areas must stay open

Ask for a quote

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to give us a call on 01277 525 020 or email a schedule or drawings.

Advice

When it isn’t the sealant

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

  • Approving fire stopping as compliant
  • Specifying the product where the designer hasn’t
  • Rework caused by others damaging completed areas

If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think.

Surfaces we seal

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

Surface by surface

Bathrooms, en suites and washrooms

In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line and baths are loaded where appropriate before sealing.

Internal decorators’ caulk

Caulk is easy to apply badly. Done properly, it saves decorators time and gives a clean line.
