Facade sealing in St Mary Hoo

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

What sets the cost

We price every job individually. The things that drive the figure:

  • Specialist products, such as fire-rated or hygienic sealants
  • Travel to remote or island sites
  • Site requirements such as inductions and permits
  • Backing rod, priming and other preparation

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

What we need to price the job

Diagnosis starts before we arrive. Tell us:

  • Whether the building will be occupied during the work
  • Your programme or deadline
  • Any specification or named product
  • Access details, including height

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or send details through our quote form to discuss it first.

Facade sealing in St Mary Hoo

Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. Most enquiries involve staining on stone next to old sealant and air leaks through failed facade joints, on window and door perimeters, shopfront frames and stone and brick facade joints. A single leaking joint is often how a building in St Mary Hoo 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.

Around smaller places like St Mary Hoo, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Doing it in-house

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

What we can’t put right

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:

  • Render or concrete edges that have broken away
  • Water getting in through cracked render or porous masonry
  • Movement beyond what any sealant can handle

Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly before you book.

Where we work in St Mary Hoo

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

Aftercare for building managers

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Avoid patch repairs on failed facade joints
  • Plan facade sealing alongside redecoration
  • Note when each elevation was last resealed
  • Inspect facade joints on a regular cycle

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.

Sites and facades in and around St Mary Hoo

St Mary Hoo lies within about 2 miles of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. At about 30 miles from central London, St Mary Hoo is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.

Hospital estates such as Medway Maritime Hospital (6 miles south-west of St Mary Hoo) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

St Mary Hoo is about 4 miles south of Canvey Island, in Medway. Looking for facade sealing in St Mary Hoo? We can help, as we do across Medway. Our Medway coverage takes in 54 places. London is covered too, some 30 miles away.

When to call us in St Mary Hoo

Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, and cracks or adhesion loss follow.

If one of these sounds familiar, it’s time for a closer look:

  • Cold air coming in at window perimeters
  • Previous reseals run over old sealant
  • Failed sealant on precast panel joints
  • Unsightly perimeter sealant on a visible elevation

For contractors on a campus like University of Greenwich - Medway (4.9 miles south-west of St Mary Hoo), facade and perimeter sealing has to fit around students and term dates.

Questions to ask before you book

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Who will actually carry out the work
  • Their pre-qualification and accreditations
  • How they’ll work around occupants

Questions to ask before you appoint anyone

From enquiry to sign-off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. For work around St Mary Hoo, 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. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Share your working hours and any access restrictions
  • Tell us which areas need to stay in use

Request a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
