Facade sealing in Finglesham

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

How we handle facade sealing in Finglesham

Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. We work on cladding panel joints, shopfront frames and perimeter joints where frames meet the structure, and what we are called in for most is perimeter sealant that has split or peeled away and water coming in around window frames. Whoever orders the work in Finglesham, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In the countryside around places like Finglesham, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email drawings and photos and we will arrange a return visit.

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Finglesham, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

After the work

Problems stay small when the joints are checked regularly. Specifically:

  • Insist on a full cut-out when joints are renewed
  • Brief window cleaners about newly sealed joints
  • Add perimeter sealant to planned maintenance checks
  • Don’t wait for a second leak before calling

Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade instead of soaking the joints.

Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in.

Different surfaces, different methods

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification.

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.

Common problems we fix in Finglesham

The wrong product causes its share of trouble: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Most external joints call for a neutral-cure, facade-grade sealant.

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

  • Weathered joints at frame-to-structure perimeters
  • Water coming in around window frames
  • Gaps between rainscreen or cladding panels
  • Draughts around frames and panels

Recladding or extending a unit at a site like Birnham Farm Business Centre, 2.9 miles to the north-west of Finglesham, brings panel joints and frame perimeters into the programme.

What your quote should include

  • What level of public liability insurance do they hold?
  • Whether old or failed sealant will be cut out, not overlaid
  • Health and safety accreditation such as CHAS
  • How the joint faces will be prepared and primed

Choosing a commercial sealant contractor

Facade sealing in Finglesham: the local picture

Finglesham sits close to the coast, within about 3 miles. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. Finglesham lies roughly 65 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.

When a school such as Northbourne Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. For a contractor working at a hospital such as Victoria Hospital, which lies south-east of Finglesham, perimeter and facade sealing is planned around patients and deliveries.

Finglesham is about 2 miles north-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, large and small. For work in that direction, see our London page.

Work on facade joints is covered throughout CT14. We also cover Marley (1 mile south-west), Hacklinge (1 mile north-east), Ham (1 mile north-west), Northbourne (1 mile south) and Sholden Meadows (1 mile south-east) for facade joints.

Questions about Finglesham

Is Finglesham too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Does your area include sites such as Birnham Farm Business Centre, near Finglesham?

Yes. Estates, retail parks and business parks around Finglesham, Birnham Farm Business Centre among them, are all within reach. A few photos and the unit address let us price the work.

Do you install glazing systems?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Can you work on upper floors?

Access is planned with you before we quote. Let us know what access is in place or planned, and the quote will reflect it.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

General trades versus a specialist

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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Owners, agents and contractors

Building owners and managing agents use us on everything from one building to a spread of sites around Finglesham. Several sites can go on one quote, which keeps the paperwork simple.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
