Construction mastic in Loughton

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What we can’t put right

Some faults sit outside our scope, and we say so rather than covering them up:

  • Rework caused by others damaging completed areas
  • Frame gaps too wide for sealant, which the installer needs to correct
  • Designing joint widths or choosing the specification (that sits with the designer)

If you are not sure, just give us a call on 01277 525 020 or send details through our quote form and we will give you a straight answer.

Surfaces we seal

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

Construction mastic in Loughton, done properly

We work to the specification and the programme rather than whatever product is to hand. If a product is named, that’s what goes in; any alternative we suggest is put to you before anything changes. Joint widths, backing, primers and tooling follow the manufacturer’s guidance so the detail on the drawing is what ends up on site. We work on sanitary and kitchen joints, window and door perimeters and floor and skirting junctions, and the usual reasons a site gets in touch are bath and shower joints scraped during the final clean and existing joints on a refurb that need cutting out and resealing. Looking for mastic applicators who cover Loughton? We’ve been sealing commercial buildings since 2005.

For a contractor on a smaller site near Loughton, one mastic visit at the right stage saves return trips. Let us know the key stages and we will time the work so nothing waits on us.

A 12-month guarantee applies to all our work in Milton Keynes. Should something we installed fail, give us a call on 01277 525 020 or email a schedule or drawings and we will come back to it.

On site: what to expect

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Several jobs near Loughton can be grouped on one trip. Tell us your site hours and we’ll plan around them.

  1. We start with the drawings, specification and programme.
  2. Quantities are measured and a fixed price returned.
  3. We agree with the site team which areas come first.
  4. Plots or floors are sealed as they’re handed over.
  5. Every joint is cleaned, set to depth and sealed with the specified product.
  6. Snags are cleared and the package signed off with our 12-month guarantee.

Preparing the site

  • Tell staff and tenants when we’ll be in
  • Arrange parking or a loading space
  • Move anything stored against the joints

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Keeping the joints sound

To get the most from the new sealant:

  • Keep product details for future maintenance
  • Ask installers to correct oversized gaps first
  • Brief following trades on areas that have been sealed
  • Don’t schedule sealing before decorators and flooring are done

Brief the sparkle clean so they don’t scrape the new joints. Blades and abrasive pads are the commonest cause of damage at the final clean so keep them off the joints.

Snag items left to the last week put handover at risk. A planned close-out through each area as it completes keeps the list short, and avoids a rush.

General trades versus a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Sites and facades in and around Loughton

Rainfall across the South East, Loughton included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager. Central London is about 47 miles from Loughton. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.

University estates such as University of Bedfordshire Milton Keynes Campus (0.9 miles north-east of Loughton) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Recladding or extending a unit at a site like Deltic Trade Park (0.6 miles north of Loughton) brings panel joints and frame perimeters into the programme.

Loughton is about 1 mile south-west of Milton Keynes, in Milton Keynes. Loughton sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.

What we’re called out for in Loughton

Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture, which opens up internal joints, particularly where caulk has been used in a joint that moves. Picking a flexible sealant where there’s movement keeps snags down.

It’s worth sending us details if you spot any of the following:

  • Missed perimeter joints on a new elevation
  • Existing joints on a refurb that need cutting out and resealing
  • Different trades sealing to different standards
  • Mastic snags holding up handover

For contractors at a school such as Loughton Manor First School, sealing has to be finished before term starts.

Before you book anyone

  • How long is the guarantee, and what does it include?
  • Whether their applicators hold CSCS cards
  • Whether primer will be used where the manufacturer specifies it
  • Their pre-qualification and accreditations
