Why deal with it now?

Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. One visit to deal with every failing joint makes more sense than several trips to a place like Little Kingshill, rather than one at a time. Photos of every joint help us quote for the whole job.

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 fixed quote and we’ll explain how it’s made up.

Little Kingshill: questions and answers

Will you plan work around the academic year at somewhere like Buckinghamshire New University?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is Little Kingshill off your patch?

No. Places such as Little Kingshill are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Can staff carry on working while you are here?

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

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Diagnose, treat, sign off

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. If others near Little Kingshill need work, visits can be combined. You will have a fixed quote before work starts.

  1. First we review photographs, 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. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Explain the parking and delivery arrangements
  • Clear stock, furniture or equipment away from the joints

Advice

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

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

Facade sealing around Little Kingshill: points for this area

Little Kingshill is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. At about 29 miles from central London, Little Kingshill is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.

Historic houses such as Hughenden Manor, 3.5 miles to the south-west of Little Kingshill, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. When a school such as Ash Hill Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Do you need facade sealing in Little Kingshill?

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

If one of these sounds familiar, it’s time for a closer look:

  • Staining on stone next to old sealant
  • Perimeter sealant that has split or peeled away
  • Draughts around frames and panels
  • Damp patches beside frames after rain

University estates such as Buckinghamshire New University (2.4 miles east of Little Kingshill) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Choosing a commercial sealant contractor

Looking after the joints

A few simple habits keep the new joints working:

  • Combine resealing with other works that need access
  • Keep pressure washers away from fresh sealant
  • Walk the elevations once or twice a year
  • Ask about asbestos in pre-2000 mastic

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

Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading.

Cost factors for facade joints

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

  • Working within restricted access windows
  • Joint width, depth and condition
  • The total length or number of joints
  • The site’s rules and procedures

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Before you send an enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • Rough lengths or quantities, or drawings if you have them
  • Asbestos survey details if the building is older
  • Any specification or named product
  • The postcode of the building

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or send details through our quote form with what you know.
