Facade sealing in Chorleywood West, done properly

Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. The enquiries we see most involve sealant pulling away from frames or panels and failed seals around shopfront and entrance frames, on coping and flashing joints, perimeter joints where frames meet the structure and shopfront frames. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Chorleywood West it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Conversions of older rural buildings near smaller places such as Chorleywood West 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 normally what’s needed.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

When to bring in a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Keeping the joints sound

Cleaning and maintenance staff play a part too. Share these points with them:

  • Avoid patch repairs on failed facade joints
  • Brief window cleaners about newly sealed joints
  • Record the product and colour used on each elevation
  • Inspect facade joints on a regular cycle

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards using a matching sealant.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Providing access systems for the work
  • Movement beyond what any sealant can handle
  • Damaged frames that need replacing

Not sure which it is? You can call 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

What we seal

  • Cladding panel joints
  • Stone and brick facade joints
  • Shopfront frames
  • Window and door perimeters
  • Coping and flashing joints
  • Perimeter joints where frames meet the structure

On site: what to expect

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. For work around Chorleywood West, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • Agree which areas must stay open
  • Clear stock, furniture or equipment away from the joints
  • Warn occupants and staff about the work

Your questions answered

Is Chorleywood West too far out for you?

Not at all. Chorleywood West is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Can you take on a job at a hospital such as Bishops Wood 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 check whether the sealant is causing the leak?

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

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

What do you charge?

We don’t publish prices, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.

Why it’s worth doing now in Chorleywood West

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 early costs far less than repairing what the water reaches. One visit to deal with every failing joint makes more sense than several trips to a place like Chorleywood West. Photos of every joint help us quote for the whole job.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

How the job changes by surface

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather and need a durable external sealant.

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end.

Facades, frames and programmes in Chorleywood West

The South East is one of the drier parts of the UK. 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. Central London is about 20 miles from Chorleywood West. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.

New units and refits on sites such as Peerglow Industrial Estate (1.8 miles south-east of Chorleywood West) need their panel and perimeter joints sealed to the specification. When a school such as Arnett Hills Junior Mixed and Infant School is extended or refurbished, the mastic package is often squeezed into the holidays. Hospital estates such as Bishops Wood Hospital (to the south-east of Chorleywood West) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
