Shops, offices and hotels in and around Notting Dale

A good number of hotels sit less than 2 miles from Notting Dale. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes; work is planned so the hotel keeps trading. The 3 miles around Notting Dale take in at least three named trading estates, business parks or retail parks. Each new occupier on a park like these tends to refit, from reception to staff kitchen.

Shops and cafés around stations like Shepherds Bush station, 0.7 miles south-west of Notting Dale, trade from early, so work is timed around them. If you run a unit on an estate such as Stable Way Industrial Estate (0.5 miles west of Notting Dale), the trade counter, offices and staff facilities have joints to look after as well as the warehouse. For a shop at a centre such as Kensington Arcade, 1.2 miles south-east of Notting Dale, tidy joints at counters and displays matter as much as the fixtures.

Sealant specialists in Notting Dale

Sometimes a split bead is a symptom rather than the cause. Water at a window perimeter might be coming from the frame, the cill or the wall behind. We look before we quote and tell you plainly if sealant won’t solve it. We work on external facade joints, window and door perimeters and movement joints in walls and floors, and what we’re called in for most is frame mastic that has hardened and come away from the wall and earlier reseals applied straight onto the failed bead. A specialist sealant contractor works differently from a general builder: in Notting Dale, that means joint design, primers and backing rod as standard.

Multi-site clients with buildings in and around Notting Dale can put several sites on one programme, with one quote format and one point of contact.

For managing agents and FMs looking after premises in Notting Dale, access is usually the first question: loading bay slots, goods lifts, permits to work and somewhere to keep materials. With access agreed, we work through the sealant joints a section at a time, keeping disruption to tenants low.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

From enquiry to sign-off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. First, details reach us through the quote form or a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Where parts of the building must stay open, the work is phased.
  4. Old sealant is cut out completely, never sealed over.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.

What we need from you

  • Have the specification and drawings to hand
  • Explain the parking and delivery arrangements
  • Flag any permit to work we’ll need

Get a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Advice

When something else is needed

Honesty saves time and money. Fresh joints won’t solve:

  • Structural cracks or movement the joints weren’t designed for
  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Suspect materials that need testing and specialist removal

If you are not sure, just phone 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Where we work in Notting Dale

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

Different surfaces, different methods

Fire-rated seals where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. The design and sign-off of fire stopping belong to the designer and building control; we install what’s specified.

Washrooms and toilets

Washroom joints take water, cleaning chemicals and constant use. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, phasing the rooms so not every toilet is closed at once.

How the quote is worked out

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Access and working height
  • Quantities, in metres or numbers
  • Phasing around occupants
  • The product specified

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Sending details for a quote

It doesn’t need to be a full survey. These details are enough to start:

  • How the joints are reached, and at what height
  • What the building is and how it’s used
  • Clear photographs of the problem areas
  • Where the site is, with the postcode

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, phone 01277 525 020 or email us.

FAQs: Notting Dale

Do you work in London buildings with loading restrictions?

Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it

Does a hotel in Notting Dale need to shut while its sealant is renewed?

In most cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.

Can one contractor look after sealant on all our buildings?

Yes. We take on runs of jobs across portfolios as well as single sites.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

How do you keep disruption to occupiers down?

We phase the work so parts of the building stay open. Tell us your site hours and access windows and we’ll plan around them.

What guarantee do you give on resealing?

Our workmanship is guaranteed for 12 months. Public liability insurance is in place too.

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 as well as contractors. We can work to your instruction process and site rules.

Doing it in-house

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll 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. Getting these wrong usually costs more in the end than doing them right.

Commercial clients in Notting Dale

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
