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

Maintenance after handover

Once the work is signed off, a little attention goes a long way:

  • Combine resealing with other works that need access
  • Check that rainwater leaves the facade the way it was designed to
  • Report water ingress at frames as soon as it shows
  • Keep the sealant details on the building file

Following storms, look inside for damp or staining near frames. An early report usually means a small reseal rather than a bigger repair.

Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and limits disruption.

How we handle facade sealing in Cade Street

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. 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. If you have damp patches beside frames after rain and cold air coming in at window perimeters, we can put it right, on coping and flashing joints, window and door perimeters and cladding panel joints alike. Whoever orders the work in Cade Street, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Construction in and around smaller places such as Cade Street is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or email the details over and we will come back to it.

Sites and facades in and around Cade Street

Cade Street lies roughly 40 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. Rainfall across the South East, Cade Street included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

Recladding or extending a unit at a site like Station Road Industrial Estate (to the west of Cade Street) brings panel joints and frame perimeters into the programme. School extensions, at buildings such as Heathfield Community College, typically run to the summer holidays, mastic included. New wings at hospitals like Hellingly Hospital (to the south of Cade Street) bring long runs of window and panel joints to seal.

Leave it or put it right?

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. One visit to deal with every failing joint makes more sense than several trips to a place like Cade Street, rather than one at a time. Send photos of each area and we’ll quote for the lot.

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Why appoint us

  • RAL and finish matching where the product range allows
  • A Constructionline member, so easy to vet
  • Commercial sealant work since 2005
  • Coloured sealants to suit the setting, where available

On site: what to expect

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. For work around Cade Street, we aim to finish in one visit, so we ask for photos 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. 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. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Advice

Honest limits

We check first that sealant really is the fix. It won’t put right:

  • Water getting in through cracked render or porous masonry
  • Render or concrete edges that have broken away
  • Replacing glass or failed glazing units

If in doubt, speak to us on 01277 525 020 or send photos by email and we’ll say what we think before you book.

Joints and surfaces we work on

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

Questions we’re asked in Cade Street

Would you work within a site like Hellingly Hospital?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Station Road Industrial Estate, near Cade Street, within your area?

Yes. Estates, retail parks and business parks around Cade Street, Station Road Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Is any job too small?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How many days will you need on site?

It depends on the scope, though a typical visit usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we will set out a timescale with the quote.

Do you use silicone for external joints?

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

Work for main contractors and building owners

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Should maintenance staff do it?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
