Westley: questions and answers

Is Westley too small for you to travel to?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Can you work on a hospital site such as Sarum Road Hospital (BMI)?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

How long does a job like this take?

It depends on the scope, though a typical visit typically 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 will set out a timescale with the quote.

Do you provide access for facade work?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you are arranging and any site restrictions, and we will price the work around it.

Can you handle several sites?

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

About our facade sealing in Westley

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. We work on perimeter joints where frames meet the structure, cladding panel joints and window and door perimeters, and what we’re called in for most is old perimeter mastic that has dried out and damp patches beside frames after rain. One point of contact handles commercial sealant work in Westley from the first photographs to the final walk-round, whether it’s one building or several.

For a site near Westley, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we will quote to suit.

Every job we finish is backed by a 12-month workmanship guarantee, in Westley as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

How a job runs

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Westley are normally planned as a single visit, so we ask for photographs 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. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Preparing the site

  • Move anything stored against the joints
  • Share the asbestos register for older buildings
  • Confirm the product named in the specification

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:

  • Joints too narrow for the movement they take, which need redesign
  • Work on the window or framing system itself
  • Cracked or spalling substrates that need repair before sealing

If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

What we seal

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

Facade sealing around Westley: points for this area

At about 63 miles from central London, Westley is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.

For contractors refurbishing units at places like Balldown Business Centre, 0.7 miles to the north-east of Westley, the mastic covers cladding panels, roller-door and window perimeters. For contractors at a college like Sparsholt College Hampshire, under half a mile north of Westley, perimeters and internal sealant are timed for the holidays.

Westley is about 4 miles north-west of Winchester, in Hampshire.

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Leave it or put it right?

Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Converted and older buildings near places like Westley tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote when you’re ready.

Why us?

  • Standard and matched colours in many product ranges
  • Sealing commercial buildings since 2005
  • Constructionline member for supplier checks
  • Failed material removed, not covered up

When to call us in Westley

New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead, so the new bead peels away within a season or two.

What tends to prompt an enquiry:

  • Previous reseals run over old sealant
  • Weathered facade joints that have lost their grip
  • Draughts around frames and panels
  • Water coming in around window frames

On a campus such as University of Winchester, 3.2 miles to the south-east of Westley, new teaching buildings and residences are usually built and refurbished around the academic year.

What your quote should include

  • What level of public liability insurance do they hold?
  • How the joint faces will be prepared and primed
  • What the guarantee covers, and for how long
  • How they’ll work around occupants

How to choose a sealant contractor

Aftercare for building managers

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Never let anyone seal over old sealant
  • Record the product and colour used on each elevation
  • Add perimeter sealant to planned maintenance checks
  • Share access with other external trades

Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly.

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