Facade sealing near East Harting

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

When to bring in a specialist

Redoing a failed joint typically costs more than getting it right at the outset, 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.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Facade sealing in East Harting, done properly

We don’t install glazing systems or replace glass. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. Most enquiries involve perimeter sealant that has split or peeled away and water coming in around window frames, on cladding panel joints, perimeter joints where frames meet the structure and window and door perimeters. A single leaking joint is often how a building in East Harting first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For a site near East Harting, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photographs and the programme and we will quote to suit.

Work we carry out in West Sussex comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or email a schedule or drawings and we will come back to it.

Your questions answered

Is East Harting too far out for you?

Not at all. East Harting is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Is hospital work, at somewhere like Petersfield Community Hospital, something you do?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

How many days will you need on site?

It depends on the scope, but the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Facades, frames and programmes in East Harting

East Harting sits in one of the drier corners of the country, the South East. 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. East Harting lies roughly 49 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.

New wings at hospitals like Petersfield Community Hospital, 4.1 miles to the north-west of East Harting, bring long runs of window and panel joints to seal. When a school such as Harting CofE Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. With historic properties like Uppark (1.7 miles south-west of East Harting) in the area, refurbishment work often meets old masonry that needs compatible sealants.

From enquiry to sign-off

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For work around East Harting, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. Access, site rules and timing are settled with the client up front.
  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.

Getting the site ready

  • Tell staff and tenants when we will be in
  • Clear stock, furniture or equipment away from the joints
  • Explain the parking and delivery arrangements

What sets the cost

The price varies from site to site. It mainly depends on:

  • Whether old sealant has to be cut out first
  • Travel to remote or island sites
  • The product specified
  • Any access equipment needed

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

What to include in your enquiry

There’s no need for a formal survey. These details are enough to start:

  • How the joints are reached, and at what height
  • When you need the work done
  • The type of building and who uses it
  • Whether an asbestos survey exists

To get a fixed quote, call the office on 01277 525 020 or send details through our quote form with the site address and an outline of the work. You can also send details through our quote form.

What we can’t put right

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Replacing glass or failed glazing units
  • Damp caused by condensation inside the building
  • Joints whose design needs changing by the specifier

If in doubt, give us a call on 01277 525 020 or email the details over and we’ll say what we think before you book.

Joints and surfaces we work on

  • Window and door perimeters
  • Cladding panel joints

What the job involves on each surface

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building, so preparation and product choice matter.

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.
