Construction mastic across Ridley

Construction mastic for commercial buildings in Ridley

We work to the specification and the programme, not to habit. If a product is named, that’s what goes in; any alternative we suggest is put to you before anything changes. Backing, primer and depth follow what the sealant maker sets out. If you have sealant knocked or painted over by other trades and inconsistent sealant finishes from plot to plot, we can help, on sanitary and kitchen joints, floor and skirting junctions and cladding and panel joints alike. Whoever orders the work in Ridley, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Construction in and around smaller places such as Ridley is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

General trades versus 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.

Certain joints really need a specialist: for example 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.

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes whatever the programme allows, since the work follows the trades as areas are released, and we clear our waste as we work. If others near Ridley need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. Drawings, the sealant specification and your programme come to us for pricing.
  2. We return a fixed quote that ties the mastic package to your programme.
  3. You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
  4. Work follows the programme, area by area, as rooms and elevations become ready.
  5. Every joint is prepared, set to depth and sealed with the specified product.
  6. We close out snagging and hand over with a 12-month guarantee.

Preparing the site

  • Share your working hours and any access restrictions
  • Point out parking and an unloading spot
  • Let us know about inductions and permits

Mastic packages on Ridley sites

Ridley sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. Central London is about 21 miles from Ridley. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.

When units on a site such as Bowes Industrial Centre, 1.3 miles east of Ridley, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. When a school such as Meopham School is extended or refurbished, the mastic package is often squeezed into the holidays.

Ridley is about 6 miles south of Northfleet, in Kent. Ridley sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 931 places in Kent. London is covered too, some 21 miles away.

We cover the TN15 postcode districts. Sites close to Ridley are covered too, including New Street (1 mile east), Hodsoll Street (1 mile south), South Street (1 mile east), New Ash Green (1 mile north-west) and Culverstone Green (2 miles south-east). Bigger towns within reach include Maidstone (11 miles south-east), Dartford (8 miles north-west), Sevenoaks (8 miles south-west), Royal Tunbridge Wells (15 miles south), Gravesend (6 miles north-east) and Tonbridge (11 miles south).

What’s near Ridley

The closest station to Ridley is Meopham station, roughly 2.6 miles north-east of the centre. A little further out are Ightham Court (4.4 miles south) and Coldrum Long Barrow (3.1 miles south-east).

Common questions from Ridley clients

Can you work at a site such as Bowes Industrial Centre, by Ridley?

Yes, sites like Bowes Industrial Centre are within our area, along with the rest of Ridley. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Is Ridley too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do your applicators hold CSCS cards?

We’re CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. Tell us what site paperwork you need and we will confirm with the quote.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Why act early in Ridley

Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area typically clears more for less disruption. We can run snagging as its own phase before handover. One visit to deal with every failing joint makes more sense than several trips to a place like Ridley. Photos of every joint help us quote for the whole job.

We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Why us?

  • CSCS-carded applicators
  • Failed material removed, not covered up
  • A Constructionline member, so easy to vet
  • One number for every site we cover

See our cost guide or our accreditations and insurance.

Surface by surface

External facade and movement joints

External movement joints often need primer, depending on the substrate. Primer goes on where the sealant maker calls for it, and seal only with a dry joint inside the product’s temperature range.

Snagging before handover

Damaged, missed or untidy joints make up most snag lists. We price snagging as part of the package or as a separate visit, depending on what suits the programme.

When to call us in Ridley

A joint without backing rod or bond-breaker often fails early. Bonded to the base of the joint and both sides, sealant can’t stretch evenly, so depth is controlled with backing rod or bond-breaker tape.

These are often picked up first by site or facilities staff:

  • Early adhesion failures on new external joints
  • Inconsistent sealant finishes from plot to plot
  • Bath and shower joints scraped during the final clean
  • Old sealant on a refurbishment that needs stripping before new work

With historic properties like Cobham College, 4 miles to the north-east of Ridley, in the area, refurbishment work often meets old masonry that needs compatible sealants.

How to choose a sealant contractor

Cost factors for mastic packages

Your fixed quote is built from the real scope. It takes account of:

  • Removal of failed or old sealant
  • Quantities, in metres or numbers
  • Which sealant the job calls for
  • Travel to remote or island sites

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

What we need to price the job

However big the job, these details speed things up:

  • Clear photographs of the problem areas
  • Any specification or named product
  • Your programme or deadline
  • The type of building and who uses it

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.
