About our facade sealing in The Haven

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces. If you are dealing with leaks at window and door perimeters and previous reseals run over old sealant, we can help, on window and door perimeters, coping and flashing joints and perimeter joints where frames meet the structure alike. A single leaking joint is often how a building in The Haven first comes to us: we look at the rest while we’re there and tell you what we find.

Around smaller places like The Haven, building work typically 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.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Quoting for work in The Haven

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

  • How much existing material needs removing
  • Access and working height
  • Distance, for remote addresses
  • Quantities, in metres or numbers

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Before you send an enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • The postcode of the building
  • Any specification or named product
  • Whether an asbestos survey exists
  • Access details, including height

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call 01277 525 020 or use the quote form.

Should maintenance staff do it?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Site maintenance staff can often handle a short internal joint. 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.

Facade sealing around The Haven: points for this area

A number of hotels sit less than 2 miles from The Haven. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. The Haven is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

For contractors refurbishing units at places like Spring Copse Business Park, which lies east of The Haven, the mastic covers cladding panels, roller-door and window perimeters.

The Haven is about 3 miles north of Billingshurst, in West Sussex. We cover The Haven and the rest of West Sussex, with the same fixed quotes and 12-month guarantee as everywhere else. Across West Sussex, 373 places are covered, including The Haven. There’s a separate page for Brighton, about 21 miles away.

Common problems we fix in The Haven

New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.

Most enquiries start with one or more of the following:

  • Failed sealant on precast panel joints
  • Damp patches beside frames after rain
  • Air leaks through failed facade joints
  • Facade joints cracked through the middle

Extensions at sites like Horsham Hospital (to the east of The Haven) normally sit beside working departments, and the mastic follows strict access rules.

What your quote should include

  • How they’ll work around occupants
  • The terms of the workmanship guarantee
  • Whether primer will be used where the manufacturer specifies it
  • Their pre-qualification and accreditations

Questions to ask before you appoint anyone

From enquiry to sign-off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and our waste is bagged and taken away as we go. Jobs in and around smaller places like The Haven are typically planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  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.

Preparing the site

  • Confirm the product named in the specification

Related advice

Keeping the joints sound

Regular inspection catches problems early. Specifically:

  • Note when each elevation was last resealed
  • Inspect facade joints on a regular cycle
  • Check the asbestos register before old mastic is disturbed
  • Share access with other external trades

Keep a note of which product went in and when. Future work can then match the product and colour across the elevation.

Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail, rather than waiting for a ceiling stain.

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Questions we are asked in The Haven

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

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Will you take on work at estates like Spring Copse Business Park, close to The Haven?

Yes. Estates, retail parks and business parks around The Haven, Spring Copse Business Park among them, are all within reach. A few photos and the unit address let us price the work.

Do you replace windows or glass?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also give us a call on 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.

Can the building stay open while you work?

In the majority of cases, yes. Phased work can be planned so areas stay in use.

Can you just add new sealant on top?

No. Overlaying is a shortcut that peels away quickly. We remove the failed sealant, clean the faces, set the depth and reseal.

Do you take on multi-site work?

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.
