Facade sealing near Great Mongeham

About our facade sealing in Great Mongeham

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. If you have new sealant peeling off old mastic and cladding panel joints that have opened up, we can help, whatever the surface. A single leaking joint is often how a building in Great Mongeham 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.

Construction in and around smaller places such as Great Mongeham is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Signs you need facade sealing in Great Mongeham

When the sealant tears down its centre, it has normally been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

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

  • Discoloured or dirty facade joints
  • Facade joints cracked through the middle
  • Old perimeter mastic that has dried out
  • Draughts around frames and panels

Older buildings in the area around Great Mongeham, such as Walmer Castle, 2 miles to the south-east of Great Mongeham, need care when sealed: the product has to suit soft or historic materials.

Our contractor checklist

Diagnose, treat, sign off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. Smaller jobs around Great Mongeham can be grouped with others nearby. A fixed quote is given before anything starts.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and the joint faces cleaned.
  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. We go over the completed work with you before leaving.

Getting the site ready

  • Point out parking and an unloading spot
  • Flag any permit to work we’ll need
  • Point out any areas we must not close

Getting a fixed quote

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:

  • Arranging specialist high-level access, which is planned with the client
  • Installing or repairing glazing systems
  • Cracked or spalling substrates that need repair before sealing

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

Surfaces we seal

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

After the work

A few simple habits keep the new joints working:

  • Report water ingress at frames as soon as it shows
  • Clear debris that holds water against joints
  • Brief window cleaners about newly sealed joints
  • Share access with other external trades

Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos.

Building owners, agents and FMs in Great Mongeham

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

Cost factors for facade joints

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

  • Backing rod, priming and other preparation
  • Quantities, in metres or numbers
  • Travel to remote or island sites
  • The site’s rules and procedures

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

Sending details for a quote

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

  • Asbestos survey details if the building is older
  • Whether the building will be occupied during the work
  • The site address and postcode
  • When you need the work done

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Facades, frames and programmes in Great Mongeham

With the shore within about 3 miles, Great Mongeham counts as a coastal location. 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. Great Mongeham is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.

For a contractor working at a hospital such as Victoria Hospital (1.3 miles east of Great Mongeham), perimeter and facade sealing is planned around patients and deliveries. Projects at schools like Hornbeam Primary School work to term dates, so mastic is programmed tightly.

Great Mongeham is about 1 mile west of Deal, in Kent. Across the CT14 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 931 places in Kent, from busy centres to rural villages. For work in that direction, see our London page.

FAQs: Great Mongeham

Does the sea air around Great Mongeham change the choice of sealant?

It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Would you work within a site like Victoria Hospital?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can you look at water coming in around a frame?

Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.
