How we handle facade sealing in Pett

Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. We work on coping and flashing joints, stone and brick facade joints and cladding panel joints, and the usual reasons a site gets in touch are failed sealant on precast panel joints and weathered facade joints that have lost their grip. Whoever orders the work in Pett, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Conversions of older rural buildings near smaller places such as Pett bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Common problems we fix in Pett

Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.

Look out for the following:

  • Air leaks through failed facade joints
  • Perimeter joints where frames meet the structure
  • Sealant pulling away from frames or panels
  • Damp patches beside frames after rain

Older buildings in the area around Pett, such as Lamb House (4.7 miles north-east of Pett), need care when sealed: the product has to suit soft or historic materials.

  • Can the work be phased to keep areas open?
  • Health and safety accreditation such as CHAS
  • Do they follow the manufacturer’s priming guidance?

How to choose a sealant contractor

Why it’s worth doing now in Pett

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. Halls, stores and units around places like Pett may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why us?

  • 12-month guarantee on workmanship
  • Constructionline member
  • Colour agreed before work starts
  • A range of standard colours, depending on the product

New build and refits around Pett

The sea is no more than about 1 mile from Pett. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. Pett 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, which is why external dates are agreed with the site manager.

On a healthcare site such as Conquest Hospital, which lies west of Pett, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Pett is about 5 miles east of Hastings, in East Sussex. Anywhere in TN35, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 308 places across East Sussex fall within our area, Pett among them. There’s a separate page for Brighton, about 35 miles away.

After the work

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Add perimeter sealant to planned maintenance checks
  • Note when each elevation was last resealed
  • Investigate damp beside windows promptly
  • Keep pressure washers away from fresh sealant

Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead.

Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail.

Our process

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Pett need work, visits can be combined. A fixed quote is given before anything starts.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and both faces cleaned back.
  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.

Before we start on site

  • Point out any areas we must not close
  • Make sure the joints can be reached
  • Let us know about inductions and permits

Quotes

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • The size and state of each joint
  • Any access equipment needed
  • Working within restricted access windows
  • How much there is to seal

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.

Details that help us quote

Diagnosis starts before we arrive. Let us know:

  • Your programme or deadline
  • Any specification or named product
  • A wide shot and a close-up of the area
  • Approximate linear metres or a joint schedule

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email drawings and photos.

Your questions answered

Is Pett off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Does the sea air around Pett change the choice of sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.

Can the building stay open while you work?

Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.

Is the work guaranteed?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
