Facade sealing for East Lavington sites

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

Signs you need facade sealing in East Lavington

When sealant lets go of a frame or panel, the cause is often the preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly.

Most enquiries start with one or more of the following:

  • Cold air coming in at window perimeters
  • Gaps between rainscreen or cladding panels
  • Hard, chalky sealant that no longer flexes
  • Water coming in around window frames

Older buildings in the area around East Lavington, such as Bignor Roman Villa, 2.9 miles south-east of East Lavington, need care when sealed: the product has to suit soft or historic materials.

Before you book anyone

  • Do they follow the manufacturer’s priming guidance?
  • Will failed sealant be removed rather than covered?
  • Will RAMS and insurance details be available?
  • Their plan for phasing and protecting the area

Choosing a commercial sealant contractor

Facade sealing for commercial buildings in East Lavington

Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. We will tell you if we think the leak is coming from somewhere sealant won’t fix. Site teams most often ask us about staining on stone next to old sealant and weathered joints at frame-to-structure perimeters, across window and door perimeters, cladding panel joints and coping and flashing joints. Facilities teams, main contractors and managing agents in East Lavington tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Construction in and around smaller places such as East Lavington 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.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

What the job involves on each surface

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.

When something else is needed

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Damp caused by condensation inside the building
  • Joints whose design needs changing by the specifier
  • Providing access systems for the work

If you are 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 East Lavington

Your questions answered

Can you take on a job at a hospital such as Midhurst Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can the mastic package for our job in East Lavington follow the site programme?

Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Should we check old sealant for asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.

What type of sealant goes on window perimeters?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them, and we work to what is specified.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Is colour matching possible?

It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

How much does the work cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.

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, which is what makes a joint last.

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Quoting for work in East Lavington

Quotes vary with the job. Expect it to depend on:

  • Joint width, depth and condition
  • Phasing around occupants
  • Site requirements such as inductions and permits
  • How much there is to seal

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What to include in your enquiry

We can often quote from photos and a few details. Please tell us:

  • The site address and postcode
  • Any dates the work must fit around
  • Photos of the joints, close up and from further back
  • How the joints are reached, and at what height

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Diagnose, treat, sign off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building, and our waste is bagged and taken away as we go. Jobs in and around smaller places like East Lavington are usually planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Getting the site ready

  • Agree which areas must stay open
  • Confirm the product named in the specification
  • Point out parking and an unloading spot

Quotes

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call the office on 01277 525 020 or email a schedule or drawings.

New build and refits around East Lavington

At about 46 miles from central London, East Lavington is within reach of the capital. 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. Rainfall across the South East, East Lavington included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.

For contractors at a school such as Graffham CofE Infant School, sealing has to be finished before term starts. Extensions at sites like Midhurst Community Hospital (5.1 miles north-west of East Lavington) normally sit beside working departments, and the mastic follows strict access rules.
