Construction mastic across Leigh Green

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Construction mastic for commercial buildings in Leigh Green

Getting a subcontractor through site induction should be simple. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we are fully insured. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. Site teams most often ask us about failed sealant in an existing building being refurbished and new external sealant already peeling away, on cladding and panel joints, internal decorators’ caulk and floor and skirting junctions. A specialist sealant contractor works differently from a general builder: in Leigh Green, that means joint design, primers and backing rod as standard.

Around smaller places like Leigh Green, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Work we carry out in Kent comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or send photos by email and we will arrange a return visit.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

What we’re called out for in Leigh Green

Dust is the enemy of adhesion on a construction site. Plaster dust, release agents, protective film residue and damp all stop sealant bonding, so preparation matters as much here as on a reseal.

Site and facilities staff are often the first to spot these:

  • Perimeter gaps outside the sealant’s range
  • Sealant knocked or painted over by other trades
  • Old sealant on a refurbishment that needs stripping before new work
  • Window and door perimeters that won’t pass inspection

Hotel extensions and refits, at places such as The Woolpack Hotel, 1.2 miles west of Leigh Green, normally run between busy periods, so the sealing is squeezed into short windows.

Comparing quotes

  • Are they CHAS accredited or on Constructionline?
  • Can the work be phased to keep areas open?
  • Is the sealant right for the movement and the substrate?
  • How joint depth will be controlled

Contractors’ notes for Leigh Green

Central London is about 46 miles from Leigh Green. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. A 2-mile radius around Leigh Green takes in a number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

For contractors refurbishing units at places like Pickhill Business Centre, 1.1 miles south-west of Leigh Green, the mastic covers cladding panels, roller-door and window perimeters. Projects at schools like Tenterden Church of England Junior School work to term dates, so mastic is programmed tightly.

Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Leigh Green can form part of a wider programme.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Our process

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a building around Leigh Green, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. First we look at the scope on site or from drawings.
  2. You receive a fixed quote covering scope, products and sequence.
  3. Paperwork is agreed and applicators are inducted on site.
  4. Sealing follows the programme as areas are released.
  5. Problems we find, such as oversized gaps, are raised right away.
  6. The package is closed out, snags cleared and backed by our 12-month guarantee.

What we need from you

  • Flag any permit to work we will need
  • Let building users know which areas are affected
  • Move anything stored against the joints

Advice

Surface by surface

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 while moving joints need a flexible sealant.

Snagging before handover

Snagging is often the final mastic stage. We can work through the snag list area by area and damaged joints are redone rather than patched.

Common questions from Leigh Green clients

Can you take on a job at a hospital such as West View Hospital?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you cover business parks and estates near Leigh Green, such as Pickhill Business Centre?

Yes. Estates, retail parks and business parks around Leigh Green, Pickhill Business Centre among them, are all within reach. A few photos and the unit address let us price the work.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Does weather affect external mastic work?

Conditions have to suit the product before external work starts. Sealing in poor conditions risks adhesion failure so it’s better to wait.

Is the mastic package guaranteed?

The work is guaranteed for 12 months, covering how we sealed. Keeping other trades off finished joints prevents most problems.

Do you work in Leigh Green?

Yes. Leigh Green falls within our area, and the simplest way to start is to ring 01277 525 020 or send details through our quote form.

Looking after the joints

To get the most from the new sealant:

  • Share drawings and the specification as soon as possible
  • Keep finished joints away from paint, plaster and scrapers
  • Put any product change through the designer first
  • Record the products used in the O&M file

Expect some settlement in the first months. Flexible sealants in the right joints handle normal movement while rigid fillers and caulk can crack where movement is larger. If that happens, let us know.

In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors. Proper preparation, with the right silicone first time, keeps it off the defects list.
