For managing agents and facilities managers

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Combine resealing with other works that need access
  • Check that rainwater leaves the facade the way it was designed to
  • Brief window cleaners about newly sealed joints
  • Insist on a full cut-out when joints are renewed

Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed instead of soaking the joints.

Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down.

Why deal with it now?

Failed joints let in more than water: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Why us?

  • Joints cleaned back to sound surfaces
  • One contact handling all your sites
  • RAL and finish matching where the product range allows
  • Colours confirmed for the specified product

What the job involves on each surface

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and areas needing repair are flagged.

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.

Your questions answered

Does your area include sites such as Colne Way Industrial Estate, near Bricket Wood?

Yes. We cover Bricket Wood and the area around it, including industrial estates, business parks and retail parks such as Colne Way Industrial Estate. Photos and a short description are enough for a first look.

Is Bricket Wood too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Can the building stay open while you work?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Who decides which product is used?

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 quote from photographs?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.

How long does a typical visit take?

It depends on the scope, though a typical visit usually takes a day or two for a few elevations, and longer where access has to be moved around the building. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Facades, frames and programmes in Bricket Wood

Bricket Wood has a number of hotels close by, all within 2 miles. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.

Older buildings in the area around Bricket Wood, such as High Elms Manor (1.1 miles west of Bricket Wood), need care when sealed: the product has to suit soft or historic materials. Projects at schools like Mount Pleasant Lane Primary School work to term dates, so mastic is programmed tightly. Hotels like Mercure Noke Hotel St Albans, 1 mile to the north of Bricket Wood, rarely close for long, so refurbishment mastic is phased floor by floor.

Bricket Wood is about 3 miles north-east of Watford, in Hertfordshire. Anywhere in AL2, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Hertfordshire coverage takes in 371 places. We also cover London, around 19 miles from Bricket Wood.

When something else is needed

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Specialist high-level access methods
  • Joints too narrow for the movement they take, which need redesign
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

If you are not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

How a job runs

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. If neighbouring businesses or buildings around Bricket Wood need work too, visits can be combined. Tell us your site hours and we’ll plan around them.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Before we start on site

  • Make sure the joints can be reached
  • Arrange parking or a loading space
  • Send any specification or drawings in advance
