Facades, frames and programmes in Southover

Southover sits in one of the drier corners of the country, the South East. 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. Southover is about 44 miles 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.

Hotels like The White Hart Hotel (under half a mile north of Southover) rarely close for long, so refurbishment mastic is phased floor by floor. When a college such as Sussex Downs College (under half a mile south-east of Southover) builds or refurbishes, the mastic package typically has to fit around students and staff. Building work at universities like University of Sussex, 4.2 miles to the west of Southover, is often timed for the summer, mastic included.

Southover is about 1 mile south-east of Lewes, in East Sussex. If you’re looking for facade sealing in Southover, we can help, as we do across East Sussex. 308 places across East Sussex fall within our area, Southover among them. We also cover Brighton, some 7 miles away.

How the job changes by surface

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish.

Common questions from Southover clients

Is Phoenix Industrial Estate, near Southover, within your area?

Yes. Estates, retail parks and business parks around Southover, Phoenix Industrial Estate among them, are all within reach. To start, just give us a call on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Is a hospital such as Lewes Victoria Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

How do we ask for a quote?

The quote form is the simplest route, though you can also phone 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.

Can the building stay open while you work?

In most cases, yes. We phase the work so most of the building stays in use.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Can you quote from photographs?

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

What affects the price in Southover

Before we quote, we look at:

  • Induction, permit and paperwork requirements
  • Access and working height
  • Distance, for remote addresses
  • The size and state of each joint

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

What we need to price the job

The more we know, the firmer the quote. Helpful details to send:

  • Any specification or named product
  • A wide shot and a close-up of the area
  • Any dates the work must fit around
  • Approximate linear metres or a joint schedule

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or use the quote form with what you know.

Doing it in-house

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.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building. Work in places the size of Southover is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Have the specification and drawings to hand
  • Send your site hours and access windows
  • Explain the parking and delivery arrangements

Advice

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Damaged frames that need replacing
  • Water getting in through cracked render or porous masonry
  • Replacing glass or failed glazing units

Not sure which it is? You can phone 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
