Facade sealing for commercial buildings in Greatham

Managing agents and owners in Greatham ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. If you have air leaks through failed facade joints and perimeter sealant that has split or peeled away, we can put it right, whatever the surface. A single leaking joint is often how a building in Greatham first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For a site near Greatham, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

How a job runs

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. Rural sites near Greatham may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  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.

Preparing the site

  • Have the specification and drawings to hand
  • Agree which areas must stay open
  • Share your working hours and any access restrictions

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

Related advice

When to call us in Greatham

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained and rips when the facade moves.

Look out for the following:

  • Perimeter sealant that has split or peeled away
  • New sealant peeling off old mastic
  • Failed seals around shopfront and entrance frames
  • Failed sealant on precast panel joints

When a school such as Greatham Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Sites and facades in and around Greatham

Rainfall across the South East, Greatham included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team. Greatham is about 45 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.

Recladding or extending a unit at a site like Longmoor Enterprise Park (less than half a mile north-east of Greatham) brings panel joints and frame perimeters into the programme. Extensions at sites like Chase Hospital, 2.5 miles north-east of Greatham, usually sit beside working departments, and the mastic follows strict access rules.

Greatham is about 5 miles north-east of Petersfield, in Hampshire. Looking for facade sealing in Greatham? We can help, as we do across Hampshire. Greatham is one of 723 places in Hampshire on our list for facade joints. We also cover Portsmouth, some 20 miles away.

Questions we’re asked in Greatham

Is Greatham too small for you to travel to?

No. Places such as Greatham are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Is a hospital such as Chase Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can you work while the building is occupied?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

Will rain stop the work?

Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start.

Do you replace failed glazing units?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Surface by surface

Precast concrete panels

Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod.

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface, and we will mention any edges that need repair.

Why deal with it now?

Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing now costs less than repairing interiors later. One visit to deal with every failing joint makes more sense than several trips to a place like Greatham, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

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

What you get with us

  • Fully insured, including public liability cover
  • Work carried out by CSCS-carded applicators
  • One number for every site we cover
  • Health and safety: CHAS accredited

See our cost guide or how we’re accredited.

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • Site requirements such as inductions and permits
  • Which sealant the job calls for
  • Phasing around occupants
  • How much there is to seal

There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Any dates the work must fit around
  • The site address and postcode
  • Asbestos survey details if the building is older
  • How the joints are reached, and at what height

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
