Facade sealing near Fernhill

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

Facade sealing in Fernhill

We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause, but not always. If the evidence points away from the sealant, we say so before quoting. If you have cold air coming in at window perimeters and failed sealant on precast panel joints, we can put it right. Looking for mastic applicators who cover Fernhill? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Conversions of older rural buildings near smaller places such as Fernhill bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.

A 12-month guarantee applies to all our work in West Sussex. Should something we installed fail, call the office on 01277 525 020 or email drawings and photos and we will come back to it.

Owners, agents and contractors

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Fernhill can form part of a wider programme across West Sussex.

Quoting for work in Fernhill

To price the job, we consider:

  • Quantities, in metres or numbers
  • How much existing material needs removing
  • Working within restricted access windows
  • Any access equipment needed

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Sending details for a quote

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Your programme or deadline
  • Photos of the joints, close up and from further back
  • The type of building and who uses it
  • Rough lengths or quantities, or drawings if you have them

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or email us.

What we’re called out for in Fernhill

When the sealant tears down its centre, it has normally been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

Things that usually lead to an enquiry:

  • New sealant peeling off old mastic
  • Failed seals around shopfront and entrance frames
  • Cladding panel joints that have opened up
  • Discoloured or dirty facade joints

New units and refits on sites such as Maple Business Park (less than half a mile east of Fernhill) need their panel and perimeter joints sealed to the specification.

What your quote should include

  • What site paperwork they can supply
  • Their pre-qualification and accreditations
  • Their plan for phasing and protecting the area
  • Their approach to joint depth and backing

How to choose a sealant contractor

Common questions from Fernhill clients

Is Fernhill too small for you to travel to?

No. Small places get the same service as large ones. 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 you take on work at healthcare sites like Spire Gatwick Park Hospital (Private)?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you work on upper floors?

That comes down to the access arranged for the job. Share what access exists or is planned when you send details, and we’ll plan the work with you.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

How long does a job like this take?

It depends on the scope, though a typical visit normally takes a day or two for a few elevations, and longer where access has to be moved around the building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Sites and facades in and around Fernhill

Fernhill 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, which is why external dates are agreed with the site manager. At about 24 miles from central London, Fernhill is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.

For a contractor at a hotel such as Marriott Courtyard Hotel (0.6 miles west of Fernhill), the mastic often has to be finished before a reopening date. Projects at schools like Oakwood School work to term dates, so mastic is programmed tightly.

From enquiry to sign-off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. Smaller jobs around Fernhill can be grouped with others nearby. A fixed quote is given before anything starts.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full.
  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.

What we need from you

  • Arrange parking or a loading space
  • Clear stock, furniture or equipment away from the joints
  • Tell us what induction or permit system the site runs

Quotes

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Advice

Doing it in-house

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

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Different surfaces, different methods

Cladding panel joints

On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them.

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed.
