How we handle commercial sealant contractors in Fortune Green

Pricing a commercial reseal is a short process. Send photos, drawings or a schedule of the joints through our quote form; you can also ring 01277 525 020 or email drawings and photos with the details. Where the photos don’t tell the full story, we arrange a site visit, followed by a fixed quote rather than an estimate that drifts. The enquiries we see most involve water staining near frames, panels or ceilings and smeared sealant across finishes from a rushed job, on washrooms and tea points, floor and threshold joints and window and door perimeters. For commercial sealant work in Fortune Green, you deal with one contact from quote to sign-off, whether it’s one building or several.

If you look after more than one building near Fortune Green, the work can be planned as one programme, so standards and paperwork match across every site.

London’s commercial stock mixes period buildings turned into offices with modern glass and steel, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.

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 are upfront about that.

Shops, offices and hotels in and around Fortune Green

The 2 miles around Fortune Green include four care or nursing homes. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound. The area within 2 miles of Fortune Green holds a good number of hotels. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter, with rooms done in turn while the rest stay let.

A business with units at The Quadrant Business Centre and Brent Cross Shopping Park needn’t use two contractors for its sealant. In hotels such as MB Hotel, 0.6 miles north-west of Fortune Green, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. For a shop at a centre such as O2 Centre, 0.8 miles south-east of Fortune Green, tidy joints at counters and displays matter as much as the fixtures.

Fortune Green is about 1 mile west of Hampstead, in Greater London. If you’re looking for commercial sealant contractors in Fortune Green, we can help, as we do across Greater London.

What we can’t put right

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Suspect materials that need testing and specialist removal
  • Structural cracks or movement the joints weren’t designed for
  • Misted, cracked or failed glazing units (a glazier’s job)

Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Where we work in Fortune Green

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

Surface by surface

Movement joints in walls and floors

A trafficked floor joint needs a different product from a wall joint. We’ll recommend the right filler or sealant for the traffic and movement; if the arrises are broken, we will say so before sealing.

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Photos from a closer viewpoint help us price, with colours confirmed for the product chosen.

Cost factors for sealant joints

We price every job individually. The main factors are:

  • Whether old sealant has to be cut out first
  • Joint width, depth and condition
  • The product specified
  • Phasing around occupants

Access often affects the price as much as the sealing: 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.

Details that help us quote

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Access details, including height
  • Your programme or deadline
  • Specification clauses that apply
  • Whether an asbestos survey exists

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to ring 01277 525 020 or email a schedule or drawings.

Fortune Green: questions and answers

Can you cope with the access rules in a London building?

Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough

Does your area include sites such as The Quadrant Business Centre, near Fortune Green?

Yes. Our area takes in Fortune Green and its surroundings, with estates and business parks such as The Quadrant Business Centre included. Photos and a short description are enough for a first look.

Do you seal on top of existing sealant?

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

Is Fortune Green in your area?

Yes. Fortune Green falls within our area, and the simplest way to start is to give us a call on 01277 525 020 or email the details over.

Do you check for asbestos before removing sealant?

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.

How long does a job like this take?

It depends on the scope, but the work normally takes a few hours to several days on most single sites, depending on joint lengths and access. For bigger or phased jobs, we’ll set out a timescale with the quote.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Diagnose, treat, sign off

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes anything from part of a day on a short run of joints to several weeks on a large phased package. Planning a London job such as one in Fortune Green starts with access. Give us the hours we can be on site and we will schedule to suit.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. We agree the order of work, access windows and site hours with you.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

Getting the site ready

  • Point out any areas we must not close
  • Let building users know which areas are affected
  • Explain the parking and delivery arrangements

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
