Facade sealing in Ridley

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

Why deal with it now?

Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. Converted and older buildings near places like Ridley tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Why appoint us

  • Products installed to the manufacturer’s instructions
  • Our applicators hold CSCS cards
  • Colour options checked against the specified product
  • Joints cleaned back to sound surfaces

How we handle facade sealing in Ridley

Facade sealants sit in the sun, rain and frost every day, so they don’t last indefinitely. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. We work on shopfront frames, window and door perimeters and cladding panel joints, and the usual reasons a site gets in touch are draughts around frames and panels and previous reseals run over old sealant. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Ridley, that means joint design, primers and backing rod as standard.

Conversions of older rural buildings near smaller places such as Ridley bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Different surfaces, different methods

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and we will mention any edges that need repair.

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building, so preparation and product choice matter.

When something else is needed

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Arranging specialist high-level access, which is planned with the client
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Cracked or spalling substrates that need repair before sealing

If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think.

Joints and surfaces we work on

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

Facade sealing in Ridley: the local picture

Ridley is in the South East, one of the UK’s drier regions. 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. Central London is about 21 miles from Ridley. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.

New units and refits on sites such as Bowes Industrial Centre, 1.3 miles to the east of Ridley, need their panel and perimeter joints sealed to the specification. Historic houses such as Cobham College, 4 miles to the north-east of Ridley, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. When a school such as Meopham School is extended or refurbished, the mastic package is often squeezed into the holidays.

Ridley is about 6 miles south of Northfleet, in Kent. Commercial clients in Ridley use us for work on facade joints. Our Kent coverage takes in 931 places. Sites around London have their own page, about 21 miles away.

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking anything from a single day to several weeks, depending on joint lengths, access and the weather. Smaller jobs around Ridley can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. Access, site rules and timing are settled with the client up front.
  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. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

What we need from you

  • Have the specification and drawings to hand
  • Arrange parking or a loading space
  • Tell us what induction or permit system the site runs

Keeping the joints sound

A few simple habits keep the new joints working:

  • Don’t wait for a second leak before calling
  • Keep pressure washers away from fresh sealant
  • Combine resealing with other works that need access
  • Insist on a full cut-out when joints are renewed

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

Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

Common questions from Ridley clients

Is Ridley off your patch?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Can you keep pace with our programme in Ridley?

Yes. The mastic is planned around your key stages. Let us know which documents your site asks for, and we will confirm them alongside the quote.

When is resealing likely to be due?

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.

Are you insured?

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

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

What type of sealant goes on window perimeters?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others.

Building owners, agents and FMs in Ridley

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
