Photos, a specification or a quick description of the joints is enough to start a fixed quote.

FAQs: Leadingcross Green

Is Leadingcross Green too small for you to travel to?

Not at all. Leadingcross Green is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Do you cover business parks and estates near Leadingcross Green, such as Roebuck Business Park?

Yes. Estates, retail parks and business parks around Leadingcross Green, Roebuck Business Park among them, are all within reach. To start, just phone 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

What about RAMS and site documents?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.

How is access to upper-level joints handled?

That varies with the building and the access on offer. When you give us a call on 01277 525 020 or use the quote form, describe the access, and we’ll plan the work with you.

How many days will you need on site?

It depends on the scope, but the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building. For bigger or phased jobs, we’ll set out a timescale with the quote.

Will you quote for a small job?

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

How we handle facade sealing in Leadingcross Green

We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause, but not always. We will tell you if we think the leak is coming from somewhere sealant won’t fix. We work on shopfront frames, window and door perimeters and coping and flashing joints, and what we are called in for most is failed seals around shopfront and entrance frames and new sealant peeling off old mastic. Whether you call it commercial sealant work, mastic application or joint sealing, in Leadingcross Green it comes down to the same thing: the right product in a properly prepared joint.

In the countryside around places like Leadingcross Green, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What sets the cost

We price every job individually. The things that drive the figure:

  • Any access equipment needed
  • Whether the work must be split into stages
  • Which sealant the job calls for
  • The size and state of each joint

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Details that help us quote

A good diagnosis starts with the right details. Tell us:

  • The site address and postcode
  • Whether an asbestos survey exists
  • Photos of the joints, close up and from further back
  • Access details, including height

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

New build and refits around Leadingcross Green

Leadingcross Green sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. Leadingcross Green is about 39 miles from central London. 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.

Hotel extensions and refits, at places such as Chilston Park Hotel (0.8 miles south of Leadingcross Green), typically run between busy periods, so the sealing is squeezed into short windows. For contractors on a campus like Canterbury Christ Church University, 2.8 miles to the north-west of Leadingcross Green, facade and perimeter sealing has to fit around students and term dates. When units on a site such as Roebuck Business Park (1.7 miles north-west of Leadingcross Green) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Leadingcross Green is about 8 miles south of Sittingbourne, in Kent. Looking for facade sealing in Leadingcross Green? We can help, as we do across Kent. We work across 931 places in Kent, large and small. We also cover London, some 39 miles away.

Different surfaces, different methods

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface, as the specification sets out.

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported first.

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Our process

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Leadingcross Green are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Tell staff and tenants when we will be in
  • Move anything stored against the joints
  • Agree which areas must stay open

Getting a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Looking after the joints

To get the most from the new sealant:

  • Combine resealing with other works that need access
  • Clear debris that holds water against joints
  • Brief window cleaners about newly sealed joints
  • Record the product and colour used on each elevation

Keep a note of which product went in and when. Future work can then match the product and colour without guesswork.

Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

What happens if it’s left?

The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. One visit to deal with every failing joint makes more sense than several trips to a place like Leadingcross Green. Photos of every joint help us quote for the whole job.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.
