Facade sealing near Monk's Hill

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How we handle facade sealing in Monk's Hill

Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. We will tell you if we think the leak is coming from somewhere sealant won’t fix. Most enquiries involve gaps between rainscreen or cladding panels and water coming in around window frames, across stone and brick facade joints, coping and flashing joints and perimeter joints where frames meet the structure. A specialist sealant contractor works differently from a general builder: on jobs in Monk's Hill, preparation and product choice get the time they need.

For a site near Monk's Hill, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we’ll quote to suit.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Leave it or put it right?

Failed joints let in more than water: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. Around Monk's Hill, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you are ready.

Why us?

  • Matching to RAL references, product permitting
  • A fixed quote before work starts
  • Specification-led, product-correct work
  • Over 20 years of commercial sealing

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Inspect facade joints on a regular cycle
  • Never let anyone seal over old sealant
  • Record the product and colour used on each elevation
  • Don’t wait for a second leak before calling

After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.

Coordinate facade sealing with other external works. Sharing the access keeps the cost down and cuts time on site.

Signs you need facade sealing in Monk's Hill

Adhesive failure, where the sealant peels away from one face, normally comes from poor preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and the joint opens with the first real movement.

Look out for the following:

  • Water coming in around window frames
  • Weathered joints at frame-to-structure perimeters
  • Staining on stone next to old sealant
  • Cladding panel joints that have opened up

For a contractor working at a hospital such as Benenden Hospital, which lies south-west of Monk's Hill, perimeter and facade sealing is planned around patients and deliveries.

Questions to ask before you book

  • Their plan for phasing and protecting the area
  • Whether their applicators hold CSCS cards
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • What site paperwork they can supply

FAQs: Monk's Hill

Is Monk's Hill too small for you to travel to?

No. Places such as Monk's Hill are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Can the mastic package for our job in Monk's Hill follow the site programme?

Yes, we work to the programme and the sequence the site sets. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

How long before the joints can be used?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

How long will the new sealant last?

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

Can the sealant be colour-matched?

It depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

How long does a job like this take?

That varies with the scale of the job, though a typical visit normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

What hours do you work?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

General trades versus a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Our process

Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Rural sites near Monk's Hill may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

What we need from you

  • For older buildings, check the asbestos register before work
  • Have the specification and drawings to hand
  • Explain the parking and delivery arrangements

Advice

Mastic packages on Monk's Hill sites

Monk's Hill 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, so the external programme keeps a little slack. Monk's Hill lies roughly 41 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.

When a school such as Smarden Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Surface by surface

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one, with masked edges for a clean line.

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. We clean back to sound material and flag edges that need repair.
