Facade sealing for commercial buildings in Hadlow

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. Most enquiries involve weathered joints at frame-to-structure perimeters and new sealant peeling off old mastic, on cladding panel joints, coping and flashing joints and shopfront frames. Most enquiries from Hadlow start with one failed joint and grow into a wider look at the building: 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 Hadlow, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photographs and the programme let us give a fixed quote.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

When it isn’t the sealant

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Damp caused by condensation inside the building
  • Movement beyond what any sealant can handle
  • Damaged frames that need replacing

If you’re not sure, just call 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

Owners, agents and contractors

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

Common problems we fix in Hadlow

Sometimes the substrate is the problem: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.

Any of the following is a good reason to get the joints checked over:

  • Old perimeter mastic that has dried out
  • Perimeter sealant that has split or peeled away
  • Failed seals around shopfront and entrance frames
  • Damp patches beside frames after rain

New units and refits on sites such as The Alders Industrial Estate (to the north-east of Hadlow) need their panel and perimeter joints sealed to the specification.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • Whether old or failed sealant will be cut out, not overlaid
  • How they handle RAMS and site documents
  • Their plan for phasing and protecting the area

How to choose a sealant contractor

Our process

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Smaller jobs around Hadlow can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full.
  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. We go over the completed work with you before leaving.

Getting the site ready

  • For older buildings, check the asbestos register before work
  • Tell staff and tenants when we’ll be in
  • Flag any permit to work we will need

Ask for a quote

For a fixed quote, phone 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. You can also send details through our quote form.

Advice

Cost factors for facade joints

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • How much existing material needs removing
  • Induction, permit and paperwork requirements
  • Which sealant the job calls for
  • How accessible the joints are

A quote for facade joints depends on quantities, condition and access. Call for a quote.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Rough lengths or quantities, or drawings if you have them
  • The asbestos register, for older buildings
  • The product your specification calls for
  • A wide shot and a close-up of the area

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Looking after the joints

After handover, these steps help:

  • Inspect facade joints on a regular cycle
  • Avoid patch repairs on failed facade joints
  • Note when each elevation was last resealed
  • Don’t wait for a second leak before calling

Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.

Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in instead of after the damage.

FAQs: Hadlow

Is Hadlow too small for you to travel to?

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

Can you work at a site such as The Alders Industrial Estate, by Hadlow?

Yes, sites like The Alders Industrial Estate are within our area, along with the rest of Hadlow. To start, just call 01277 525 020 or email us with the unit, the joints involved and your access times.

Can you work on upper floors?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you’re arranging and any site restrictions, and the quote will reflect it.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

How many days will you need on site?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Do you use silicone for external joints?

It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing, and we work to what is specified.

Sites and facades in and around Hadlow

At about 26 miles from central London, Hadlow is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.

Work at a hotel such as Hadlow Manor Hotel (1 mile north-east of Hadlow) tends to be programmed around bookings, mastic included. For contractors on a campus like University of Kent - Tonbridge, which lies south-west of Hadlow, facade and perimeter sealing has to fit around students and term dates.

Hadlow is about 3 miles north-east of Tonbridge, in Kent. We send applicators to Hadlow for facade joints, handled exactly as we handle every other area. We work across 931 places in Kent, large and small. Our London page has more on work in that area (26 miles or so).
