Coloured sealant in Greengate

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

About our coloured sealant in Greengate

We can agree a short trial length before the full run. Cured sealant may look a shade different from the wet bead, and lighting changes it again, so approving a sample on site is worth doing. Tell us who needs to approve the colour and we’ll plan for it. The enquiries we see most involve fit-outs with a sealant colour in the specification and coloured joints that have cracked with movement, on natural stone and brick, powder-coated and anodised frames and shop-fit joinery and counters. Searching for sealant specialists in Greengate? We’ve been sealing commercial buildings since 2005.

Much of the planning for a London commercial job is about getting in and out: booked loading, goods-lift times, the permit system and a place to stage materials. Once that’s settled, the colour-matched joints are resealed in sections so tenants are disturbed as little as possible.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Looking after the joints

For the best life from the joints:

  • Look at the cured colour before the full run
  • Keep harsh solvents away from visible joints
  • Ask contractors to check the colour before resealing
  • Plan full-run reseals on visible elevations

Include coloured sealant in planned building checks. Watch for cracks, peeling or discolouration and deal with problems early.

Plan resealing of visible joints before they look tired. A planned reseal avoids a run of patch repairs across the building.

What the job involves on each surface

Natural stone

Stone has variation, so the aim is a colour that sits naturally against it. A stone-compatible, neutral-cure sealant avoids staining.

Hotel interiors

Hotels use colour-matched sealant in bathrooms, bedrooms and public areas. Sanitary silicone comes in colours too, so bathrooms can match the tiling or stone.

Site staff or a sealant specialist?

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.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Sealant on show in Greengate’s commercial buildings

Less than 3 miles from Greengate there are at least three named estates and business parks. Sites like these see regular refits, with shopfronts, offices and staff areas to seal. Most London commercial buildings run contractors through a reception, a permit system and booked goods-lift slots. Our planning starts from those rules rather than working round them later.

Refits at hotels like Prince Regent Hotel (1 mile south of Greengate) bring joints at vanity tops, bars and reception desks that guests see every day. If you run an office at a site such as Mint Business Park (0.8 miles south of Greengate), the sealant at reception desks, tea points and frames ages with each fit-out. If you have premises on more than one site, say at Mint Business Park and Manor Road Retail Park, one contractor and one quote can cover both.

Greengate is about 4 miles east of Whitechapel, in Greater London. We cover commercial sites throughout Greengate. Our Greater London coverage takes in 764 places, from busy centres to rural villages. Our London page has more on work in that area.

Business premises anywhere in E13, E6 and E16 are within our area for colour-matched joints. We cover commercial and managed buildings on May Road, Emma Road and Cave Road. We also cover Plaistow (1 mile south-west), Upton Park (1 mile north-east), Upton (1 mile north), West Ham (1 mile north-west) and Canning Town (1 mile south) for colour-matched joints. A short drive away, we cover London (6 miles west), City of Westminster (8 miles west), Marylebone (8 miles west), Kensington (10 miles west), St Pancras (6 miles west) and Shoreditch (5 miles west).

Around Greengate

Around Greengate, our work takes us to commercial buildings near Coach And Horses Public House, Lister Community School and West Ham Park. Greengate’s nearest station is West Ham station, about 1 mile west of the centre. Nearby you’ll also find West Ham United Football Club Museum (0.6 miles north-east) and Stratford Centre (1.5 miles north-west). For a walk, there’s Old Ford Island and Tower Hill.

Our process

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. Planning a London job such as one in Greengate starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.

  1. We confirm the product the joint needs before talking about colour.
  2. Colour references, samples or photographs of the finish are checked against the product’s range.
  3. Where colour is critical, a sample bead can be agreed in a discreet spot.
  4. We take out the existing bead, clean the joints and fit backing.
  5. We apply the agreed colour and tool it neatly, with masking where the finish needs it.

Preparing the site

  • Warn occupants and staff about the work
  • Explain the parking and delivery arrangements
  • Clear stock, furniture or equipment away from the joints

What affects the price in Greengate

A fixed quote reflects the actual work. It takes account of:

  • Phasing around occupants
  • Whether old sealant has to be cut out first
  • Induction, permit and paperwork requirements
  • Distance, for remote addresses

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Sending details for a quote

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

  • How the joints are reached, and at what height
  • The site address and postcode
  • Your programme or deadline
  • The asbestos register, for older buildings

Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, give us a call on 01277 525 020 or email drawings and photos.

For managing agents and facilities managers

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Greengate can form part of a wider programme across Greater London.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

Questions we’re asked in Greengate

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

In most cases no closure is needed: we work room by room or floor by floor. Tell us your quiet periods and access windows and we’ll plan around them.

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

Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. We allow for the ULEZ, which covers every borough

How do you choose the sealant?

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.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

Is Greengate in your area?

Yes. Greengate is in our area, within our coverage of Greater London, South East England and Scotland. For a quote, phone 01277 525 020 or send details through our quote form.

Is coloured sealant weaker than white?

The colour doesn’t change what kind of sealant it is. Preparation, backing and tooling are what make it last.

Can you work to a RAL reference?

Yes. RAL references are a common way to specify sealant colour. We’ll confirm the colours available for the specified product and agree the nearest option.
