South Street: questions and answers

Can you take on a job at a hospital such as Eastbridge Hospital of St Thomas the Martyr?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Can you keep pace with our programme in South Street?

Yes, we work to the programme and the sequence the site sets. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Do you cover South Street?

Yes. We cover South Street, and the simplest way to start is to give us a call on 01277 525 020 or email the details over.

Can you find out why a window is leaking?

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.

How long does a job like this take?

That varies with the scale of the job, though a typical visit normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. For bigger or phased jobs, we’ll set out a timescale with the quote.

Will you quote for a small job?

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

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Facade sealing in South Street

External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. 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. If you are dealing with unsightly perimeter sealant on a visible elevation and gaps between rainscreen or cladding panels, we can put it right. Facilities teams, main contractors and managing agents in South Street tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Construction in and around smaller places such as South Street 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 ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Keeping the joints sound

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Share access with other external trades
  • Clear debris that holds water against joints
  • Avoid patch repairs on failed facade joints
  • Record the product and colour used on each elevation

Keep a note of which product went in and when. Future work can then match the product and colour without guesswork.

Coordinate facade sealing with other external works. Sharing the access keeps the cost down.

Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Our process

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Smaller jobs around South Street can be grouped with others nearby. You’ll have a fixed quote before work 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. 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.

Getting the site ready

  • Make sure the joints can be reached
  • Tell us your opening times and when work is allowed
  • Have the specification and drawings to hand

When to call us in South Street

When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.

What tends to prompt an enquiry:

  • Patch repairs that keep failing
  • Failed sealant on precast panel joints
  • Perimeter sealant that has split or peeled away
  • Draughts around frames and panels

For contractors at a school such as Boughton-under-Blean and Dunkirk Primary School, sealing has to be finished before term starts.

Before you book anyone

  • Their plan for phasing and protecting the area
  • Which product they’ll use, and why it suits the joint
  • Their public liability cover
  • How the existing material will be dealt with

Choosing a commercial sealant contractor

Why it’s worth doing now in South Street

If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice, saving a second set-up. One visit to deal with every failing joint makes more sense than several trips to a place like South Street, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

What you get with us

  • Workmanship guaranteed for 12 months
  • Coloured sealants to suit the setting, where available
  • CHAS accredited contractor
  • RAL and finish matching where the product range allows

Take a look at how commercial sealant jobs are priced or how we’re accredited.

What we can’t put right

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Replacing glass or failed glazing units
  • Arranging specialist high-level access, which is planned with the client
  • Joints too narrow for the movement they take, which need redesign

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

What we seal

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

Facade sealing around South Street: points for this area

At about 47 miles from central London, South Street is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. Rainfall across the South East, South 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, which is why external dates are agreed with the site manager.

On a healthcare site such as Eastbridge Hospital of St Thomas the Martyr, 5.7 miles to the east of South Street, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Older buildings in the area around South Street, such as Belmont House and Gardens, which lies west of South Street, need care when sealed: the product has to suit soft or historic materials.

South Street is about 3 miles south-east of Preston, in Kent. Looking for facade sealing in South Street? We can help. South Street is one of 931 places in Kent on our list for facade joints. We also cover London, some 47 miles away.

We also cover Crouch (1 mile north-west), Oversland (1 mile east), Neames Forstal (1 mile south-west), Hickmans Green (1 mile north-east) and Winterbourne (1 mile east). A short drive away, we cover Ashford (10 miles south), Canterbury (6 miles east), Sittingbourne (10 miles north-west), Whitstable (6 miles north-east), Faversham (3 miles north-west) and Herne Bay (10 miles north-east).
