Facade sealing in Upper Halling

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle facade sealing in Upper Halling

Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. The enquiries we see most involve draughts around frames and panels and perimeter sealant that has split or peeled away, on shopfront frames, coping and flashing joints and window and door perimeters. One point of contact handles commercial sealant work in Upper Halling from the first photographs to the final walk-round, for single jobs and planned programmes alike.

For a site near Upper Halling, 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.

Work we carry out in Medway comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or use the quote form and we’ll arrange a return visit.

When to call us in Upper Halling

The wrong product causes its share of trouble: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Most external joints call for a neutral-cure, facade-grade sealant.

Site and facilities staff are often the first to spot these:

  • Gaps between rainscreen or cladding panels
  • Damp patches beside frames after rain
  • Perimeter sealant that has split or peeled away
  • Weathered facade joints that have lost their grip

On a healthcare site such as St. Catherine's Hospital, 4.2 miles to the north-east of Upper Halling, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Choosing a commercial sealant contractor

Surface by surface

Window and door perimeters

Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch as the frame moves.

Precast concrete panels

Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair first.

Contractors’ notes for Upper Halling

Upper Halling is in the South East, one of the UK’s drier regions. 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. Upper Halling lies roughly 25 miles out 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 New Hythe Business Park (2.9 miles south-east of Upper Halling) brings panel joints and frame perimeters into the programme. Older buildings in the area around Upper Halling, such as Starkey Castle, which lies north-east of Upper Halling, need care when sealed: the product has to suit soft or historic materials.

Upper Halling is about 4 miles south-west of Rochester, in Medway. We cover commercial sites throughout Upper Halling, for single jobs and planned programmes alike. Our Medway coverage takes in 54 places, large and small. For work in that direction, see our London page (25 miles or so).

Commercial sites across ME2 are covered for facade joints. If your site is on The Street, Browndens Road and Meadow Crescent or close by, send details and we will quote for facade joints. We also cover Halling (1 mile north-east), Holborough (1 mile south-east), Paddlesworth (1 mile south), Wouldham (1 mile east) and North Halling (1 mile north-east) for facade joints. Further afield, our area takes in Gillingham (7 miles east), Chatham (4 miles east), Rochester (4 miles north-east), Rainham (8 miles east), Strood (4 miles north-east) and Luton (5 miles east).

How a job runs

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Rural sites near Upper Halling may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  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. We remove the old bead and check the edges are sound.
  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.

When it isn’t the sealant

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Providing access systems for the work
  • Installing or repairing glazing systems
  • Movement beyond what any sealant can handle

If in doubt, phone 01277 525 020 or use the quote form and we will say what we think.

Where we work in Upper Halling

  • Stone and brick facade joints

For managing agents and facilities managers

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Upper Halling can form part of a wider programme across Medway.

Looking after the joints

Problems stay small when the joints are checked regularly. Specifically:

  • Keep sills, gutters and drainage paths clear
  • Keep pressure washers away from fresh sealant
  • Never let anyone seal over old sealant
  • Investigate damp beside windows promptly

Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and work stops until it’s tested if it’s suspected.

Questions about Upper Halling

Can you work around term dates at a campus such as University for the Creative Arts - Rochester?

Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is Upper Halling off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

How much does the work cost?

Every job gets its own fixed quote. To get one, call the office on 01277 525 020 or use the quote form.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

Do you replace failed glazing units?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, such as perimeter joints where frames meet the structure.
