Facade sealing for Kippington sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Leave it or put it right?

Failed joints let in more than water: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

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 fixed quote when you’re ready.

Facade sealing in Kippington

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, often at around 2:1 width to depth, as the manufacturer advises. Most enquiries involve perimeter sealant that has split or peeled away and new sealant peeling off old mastic, across cladding panel joints, coping and flashing joints and perimeter joints where frames meet the structure. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Kippington is the same: the right product in a properly prepared joint.

Building work in places the size of Kippington is normally small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

On site: what to expect

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. If neighbouring businesses or buildings around Kippington need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  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. 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. We hand over with our 12-month workmanship guarantee.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Confirm the product named in the specification
  • Tell us what induction or permit system the site runs

Advice

How the job changes by surface

Window and door perimeters

Window and door perimeters make up most facade sealing work. A low-modulus neutral-cure product, chosen for the frame and wall, goes in.

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.

Building owners, agents and FMs in Kippington

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

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

What we’re called out for in Kippington

Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back and rips when the facade moves.

Most enquiries start with something like this:

  • New sealant peeling off old mastic
  • Damp patches beside frames after rain
  • Cladding panel joints that have opened up
  • Old perimeter mastic that has dried out

Hospital estates such as Sevenoaks Hospital (to the north-east of Kippington) 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.

What your quote should include

  • Do they follow the manufacturer’s priming guidance?
  • The named product and why it was chosen
  • How they’ll work around occupants
  • How joint depth will be controlled

Our contractor checklist

New build and refits around Kippington

Kippington sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Kippington is about 20 miles from central London. 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.

Older buildings in the area around Kippington, such as Knole House, 1.2 miles to the east of Kippington, need care when sealed: the product has to suit soft or historic materials. Hotel extensions and refits, at places such as The Royal Oak Hotel (0.7 miles south-east of Kippington), typically run between busy periods, so the sealing is squeezed into short windows.

Kippington is about 1 mile south of Sevenoaks, in Kent. Any commercial site in Kippington is covered, whether it’s a single job or part of a planned programme. We work across 931 places in Kent. London is covered too, some 20 miles away.

We cover the TN13, TN14 and TN15 postcode districts for facade joints. We cover commercial and managed buildings on Glebe Lane, Beech Road and Grange Road. We also cover Sevenoaks (1 mile north), Bessels Green (1 mile north-west), Riverhead (1 mile north), Dunton Green (2 miles north) and Chipstead (2 miles north-west). Bigger towns within reach include Maidstone (15 miles east), Dartford (12 miles north), Royal Tunbridge Wells (10 miles south), Gravesend (14 miles north-east), Tonbridge (7 miles south-east) and Northfleet (13 miles north-east).

Local landmarks in Kippington

Recent enquiries here include premises near Montreal Park, New Beacon School and Knole Academy and the streets around them. Kippington’s nearest station is Sevenoaks station, about 0.5 miles north of the centre. A little further out are Kemsing Castle Bank (3.3 miles north-east) and Sevenoaks Museum (0.7 miles east). For a walk, there’s Dryhill Nature Reserve.

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Kippington off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Is colour matching possible?

That depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Can you handle several sites?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Can you fit around our working hours?

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