Working on commercial sites near Old Oak Common

In London, commercial buildings often have managed loading bays, goods lifts and permit-to-work systems. We plan around them and agree phasing so tenants and customers aren’t disrupted. At least three named trading, business or retail sites lie within about 3 miles of Old Oak Common. Sites like these see regular refits, with shopfronts, offices and staff areas to seal, often in a colour the occupier specifies.

Shops and cafés around stations like Willesden Junction station (under half a mile north of Old Oak Common) trade from early, so work is timed around them. For a shop at a centre such as Stadium Retail Park, which lies north-west of Old Oak Common, tidy joints at counters and displays matter as much as the fixtures. On estates like Apex Industrial Estate, less than half a mile to the north-east of Old Oak Common, the office and welfare end of each unit has its own sealant to maintain.

Commercial sealant contractors in Old Oak Common

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. Before anything is cut out, we ask for the asbestos register or survey, since managing asbestos is the dutyholder’s responsibility. If a material is suspected, work stops until it’s tested. We work on kitchen worktops and splashbacks, window and door perimeters and movement joints in walls and floors, and the failures we are asked to look at most are wall and floor joints that have lost their seal and earlier reseals applied straight onto the failed bead. Whoever orders the work in Old Oak Common, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

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

Much of the planning for a London commercial job is about getting in and out: loading bay slots, goods lifts, permits to work and somewhere to keep materials. Once that’s settled, the sealant joints are resealed in sections so tenants are disturbed as little as possible.

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

Why act early in Old Oak Common

On many buildings the mastic was done by whichever trade was on site. Choosing the product, setting the depth and preparing the faces are what a specialist brings, the three things that decide how long a joint lasts. You notice the difference years later, not on the day. Getting scaffold, permits or access booked in Old Oak Common takes effort, so it makes sense to deal with every failing joint while access is in place.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why us?

  • 12-month guarantee on workmanship
  • Commercial sealant work since 2005
  • Work to your specification and the manufacturer’s guidance
  • CSCS-carded applicators

Take a look at what affects the cost or how we’re accredited.

Honest limits

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Faulty windows rather than failed perimeter sealant
  • Walls or slabs moving more than any sealant can take
  • Water from a services leak rather than a joint

If in doubt, give us a call on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

Joints and surfaces we work on

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

After the work

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

  • Brief cleaning contractors to avoid scourers and blades on sealant
  • Keep barriers up until the new sealant has cured
  • Have extract fans checked so wet areas dry out
  • Ask fit-out and M&E contractors to report any sealant they disturb

Brief your cleaning team on the joints that have been resealed. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces.

Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.

Questions we’re asked in Old Oak Common

Is Apex Industrial Estate, near Old Oak Common, within your area?

Yes. We cover Old Oak Common and the area around it, including industrial estates, business parks and retail parks such as Apex Industrial Estate. To start, just call 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Do hotels near Old Oak Common have to close for sealant work?

In the majority of cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.

Do you check for asbestos before removing sealant?

It can, on some older buildings. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can you take on work for an FM or managing agent?

Yes. A large share of our work comes through facilities managers, managing agents and landlords, alongside main contractors. We can work to your instruction process and site rules.

Which site documents can you send us?

The paperwork is agreed with the quote: RAMS, an insurance certificate and CSCS details are the usual requests. Every applicator holds a CSCS card.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

How the quote is worked out

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Quantities, in metres or numbers
  • Distance, for remote addresses
  • Whether the work must be split into stages
  • Any access equipment needed

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.

Sending details for a quote

Good information means a firmer quote. Helpful details to send:

  • Photos of the joints, close up and from further back
  • Whether the building will be occupied during the work
  • Where the site is, with the postcode
  • Rough lengths or quantities, or drawings if you have them

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, ring 01277 525 020 or email a schedule or drawings.

Our process

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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. A fixed quote follows, with removal and preparation included.
  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. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000
  • Have the specification and drawings to hand
