Facade sealing for businesses in Adversane

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Facade sealing in Adversane, done properly

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. We work on cladding panel joints, window and door perimeters and shopfront frames, and what we’re called in for most is failed sealant on precast panel joints and sealant pulling away from frames or panels. Whoever orders the work in Adversane, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Sites around smaller places like Adversane can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photographs and the programme and we will quote to suit.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Don’t wait for a second leak before calling
  • Inspect facade joints on a regular cycle
  • Clear debris that holds water against joints
  • Confirm the survey covers external sealants in older buildings

Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly.

Coordinate facade sealing with other external works. One set-up for several trades saves money and cuts time on site.

Diagnose, treat, sign off

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. For work around Adversane, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

What we need from you

  • Tell us what induction or permit system the site runs
  • Explain the parking and delivery arrangements
  • Let building users know which areas are affected

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

When something else is needed

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Movement beyond what any sealant can handle
  • Installing or repairing glazing systems
  • Arranging specialist high-level access, which is planned with the client

If you’re not sure, just call the office on 01277 525 020 or email the details over and we will give you a straight answer.

Where we work in Adversane

  • Stone and brick facade joints

Quoting for work in Adversane

A fixed quote reflects the actual work. It allows for:

  • Working within restricted access windows
  • Joint width, depth and condition
  • How accessible the joints are
  • The total length or number of joints

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Details that help us quote

A few photos plus some basic facts will normally do. Please tell us:

  • Anything awkward about access or site hours
  • Photos of the joints, close up and from further back
  • The product your specification calls for
  • Drawings or a marked-up plan, if available

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or email drawings and photos.

Surface by surface

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification with a product suited to glazing perimeters.

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and we will mention any edges that need repair.

Your questions answered

Is Adversane off your patch?

Not at all. Adversane is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is Gillman's Industrial Estate, near Adversane, within your area?

Yes. We cover Adversane and the area around it, including industrial estates, business parks and retail parks such as Gillman's Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

Are you fully insured?

Yes. We are fully insured, including public liability cover.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Will you check whether the sealant is causing the leak?

Yes. We check the sealant joints and report what we find before quoting. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Contractors’ notes for Adversane

At about 38 miles from central London, Adversane is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.

Recladding or extending a unit at a site like Gillman's Industrial Estate (1.2 miles north-east of Adversane) brings panel joints and frame perimeters into the programme. When a school such as The Weald School is extended or refurbished, the mastic package is often squeezed into the holidays. With historic properties like Old Place Manor, 3.2 miles to the south-west of Adversane, in the area, refurbishment work often meets old masonry that needs compatible sealants.

Adversane is about 8 miles south-west of Horsham, in West Sussex. Businesses, contractors and managing agents in Adversane can call on us for facade joints, as part of our coverage of West Sussex.
