FAQs: Temple Fortune

Must a hotel around Temple Fortune close while you work?

Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.

Will you take on work at estates like Brent Cross Shopping Park, close to Temple Fortune?

Yes. Estates, retail parks and business parks around Temple Fortune, Brent Cross Shopping Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

What guarantee do you give on resealing?

The work is guaranteed for 12 months. Should a joint we sealed give trouble during those 12 months, let us know and we will look at it.

How do we get a quote?

Photos, drawings or a schedule of the joints are normally enough to start. Where we need to see it, we will arrange a site visit, then send a fixed quote.

Do you take on multi-site sealant work?

Yes. Give us the sites and the scope at each, and fixed prices follow, with a suggested sequence.

Can areas stay open during the work?

Most of the buildings we work in stay occupied. We agree the order of areas, protect what’s nearby and close off only the section we are sealing.

What about asbestos in old mastic?

It’s possible in older buildings, especially those built before 2000. Before cutting anything out, we ask for the asbestos register or survey, and if something is suspected, work stops until it’s tested.

A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead. If you have earlier reseals applied straight onto the failed bead and shrunken sealant along kitchen worktops and splashbacks, we can put it right, whatever the surface. A single leaking joint is often how a building in Temple Fortune first comes to us: we look at the rest while we’re there and tell you what we find.

Occupied buildings in Temple Fortune need the work phased: we agree the order with you and hand back each area with its cure time.

Buildings in a London area such as Temple Fortune rarely close for maintenance: occupied offices, ground-floor retail under residential floors and busy shared entrances. Work is split into zones agreed with the building or facilities manager, so the premises keep working around us.

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

Looking after the joints

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Log reseals in the O&M or maintenance records
  • Add sealant to the planned maintenance inspection list
  • Don’t let cleaning or traffic back on before the cure time is up
  • Make sure ventilation in wet areas is switched on and working

Good ventilation keeps wet-area sealant in better condition. Fans that are broken or switched off leave joints damp for longer, and mould follows damp. Your maintenance team can look at extract fans at the same time.

In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Environmental health officers look at how cleanable surfaces are, which makes sound joints worth keeping on top of.

Should maintenance staff do it?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Why it’s worth doing now in Temple Fortune

Sealant is often treated as an afterthought by the trade that fitted the element. A specialist applicator takes care of product choice, joint depth and preparation, the three things that decide how long a joint lasts. It shows over the following seasons rather than at handover. Getting scaffold, permits or access booked in Temple Fortune takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Why clients in Temple Fortune choose us

  • Colours chosen to suit frames, cladding or finishes where possible
  • Commercial sealant work since 2005
  • Old sealant cut out, never sealed over
  • Colour agreed before work starts

See our cost guide and our accreditations and insurance.

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • Cracking that needs a structural engineer to look at it

Not sure which it is? You can call 01277 525 020 or send details through our quote form and we will tell you honestly.

Surfaces we seal

  • Window and door perimeters
  • External facade joints
  • Kitchen worktops and splashbacks
  • Floor and threshold joints
  • Movement joints in walls and floors
  • Washrooms and tea points

From enquiry to sign-off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  1. You send photographs, drawings or a list of the joints and areas involved, or we arrange a site visit.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Preparing the site

  • Share the asbestos register for older buildings
  • Explain the parking and delivery arrangements
  • Move anything stored against the joints
