Facade sealing for Upper Hardres sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Keeping the joints sound

Once the work is signed off, a little attention goes a long way:

  • Clear debris that holds water against joints
  • Investigate damp beside windows promptly
  • Insist on a full cut-out when joints are renewed
  • Confirm the survey covers external sealants in older buildings

Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal across the elevation.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos.

Facade sealing in Upper Hardres

Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. If you have staining on stone next to old sealant and cladding panel joints that have opened up, we can help. One point of contact handles commercial sealant work in Upper Hardres from the first photos to the final walk-round, whether it’s one building or several.

Conversions of older rural buildings near smaller places such as Upper Hardres 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 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

When something else is needed

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Render or concrete edges that have broken away
  • Joints too narrow for the movement they take, which need redesign
  • Installing or repairing glazing systems

Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Joints and surfaces we work on

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

Building and refurbishing in Upper Hardres

Upper Hardres is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. Upper Hardres lies roughly 54 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

Building work at universities like University for the Creative Arts, 4.1 miles north of Upper Hardres, is often timed for the summer, mastic included. On a healthcare site such as Kent and Canterbury Hospital, 3.5 miles north of Upper Hardres, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Upper Hardres is about 4 miles south of Canterbury, in Kent. Commercial clients in Upper Hardres can call on us for facade joints, as part of our coverage of Kent. Across Kent, 931 places are covered, Upper Hardres among them. London is covered too, around 54 miles from Upper Hardres.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Upper Hardres, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Let building users know which areas are affected
  • Confirm the product named in the specification
  • Move anything stored against the joints

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • Access and working height
  • Backing rod, priming and other preparation
  • Travel to remote or island sites
  • How much there is to seal

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

Before you send an enquiry

Good information means a firmer quote. When you get in touch, include:

  • Whether an asbestos survey exists
  • Any specification or named product
  • Your programme or deadline
  • Photos of the joints, close up and from further back

Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, speak to us on 01277 525 020 or send photos by email.

General trades versus a specialist

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Questions we’re asked in Upper Hardres

Could you schedule work at a campus like University for the Creative Arts for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is a hospital such as Kent and Canterbury Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

What will the job cost?

Each job is quoted on its own details. To get one, ring 01277 525 020 or email a schedule or drawings with a description of the work.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Do you replace failed glazing units?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, including perimeters where frames meet the structure.

What happens if it’s left?

If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice. Halls, stores and units around places like Upper Hardres may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
