Coloured sealant near Adelphi

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Coloured sealant for commercial buildings in Adelphi

A colour-matched bead still has to work as a seal. Faces are prepared, depth is fixed with rod and the bead is tooled onto two sides only. Careful masking keeps the edges crisp. We work on shop-fit joinery and counters, cladding panels and natural stone and brick, and the usual reasons a site gets in touch are patch repairs in several different colours and failed coloured sealant that has split or peeled. Most enquiries from Adelphi start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

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.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

When something else is needed

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

  • Overpainting a joint that needs a non-paintable product
  • A guaranteed perfect match to every finish
  • Cleaning or repairing the surrounding finishes

If in doubt, phone 01277 525 020 or email the details over and we’ll say what we think before you book.

What we seal

  • Hotel bathrooms and public areas
  • Powder-coated and anodised frames
  • Office fit-out finishes
  • Shop-fit joinery and counters
  • Natural stone and brick
  • Cladding panels

Different surfaces, different methods

Cladding panels

Panel joints form a grid on the facade, so colour matters. The colour is picked from the range of a sealant that suits the panel joint, suited to the expected movement.

Natural stone

Sandstone, limestone and granite each have distinct tones. We choose from the product’s range and agree the colour with you.

Questions we are asked in Adelphi

Is Grand Vitesse Industrial Estate, near Adelphi, within your area?

Yes, sites like Grand Vitesse Industrial Estate are within our area, along with the rest of Adelphi. To start, just ring 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Do you take on jobs in Adelphi where loading and access are tightly controlled?

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

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Can you match any colour exactly?

No. An exact bespoke match isn’t something we can promise. We’ll show you the closest colours in the specified product’s range.

Will sunlight affect the sealant colour?

Some change over time is normal. Exposure, product and colour all play a part, so no colour stays exactly the same for ever.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.

What do you charge?

There isn’t a price list, as every site differs. Send photos or drawings and we’ll price it at a fixed figure.

Owners, agents and contractors

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Adelphi can form part of a wider programme across Greater London.

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

What sets the cost

Before we quote, we look at:

  • Site requirements such as inductions and permits
  • Phasing around occupants
  • How much existing material needs removing
  • Which sealant the job calls for

There’s no price list, since every building and every scope is different. Call for a quote.

Sending details for a quote

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • The type of building and who uses it
  • The asbestos register, for older buildings
  • Access details, including height
  • Approximate linear metres or a joint schedule

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Why it’s worth doing now in Adelphi

It’s far cheaper to approve a sample than to strip and redo a full run. A sample takes little time. Getting scaffold, permits or access booked in Adelphi takes effort, so it makes sense to deal with every failing joint while access is in place.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What you get with us

  • Work carried out by CSCS-carded applicators
  • Constructionline member
  • Workmanship guaranteed for 12 months
  • CHAS accredited contractor

Commercial premises in Adelphi

London premises usually come with a building manager, booked loading and house rules for contractors. We plan around them and agree phasing so tenants and customers aren’t disrupted. Adelphi has two care or nursing homes no more than 2 miles away. In care settings, a neat joint at a kitchen worktop or a lounge window is part of keeping the place easy to clean.

Sites a few miles apart, such as Grand Vitesse Industrial Estate and Southwark Bridge Business Centre, can share one programme and one point of contact. Refits at hotels like Hotel Cecil (London), under half a mile to the north-east of Adelphi, bring joints at vanity tops, bars and reception desks that guests see every day. Shops and cafés around stations like London Charing Cross station, less than half a mile south-west of Adelphi, trade from early, so work is timed around them.

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, 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. 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. We start with photographs, drawings or a visit to see the finishes.
  2. Colour options from the specified product’s range are shared with you.
  3. The programme and access are agreed, including any phasing.
  4. We prepare each joint, prime where needed and fit backing.
  5. We seal in the approved colour and tool it smooth.

Before we start on site

  • Tell us which areas need to stay in use
  • Share your working hours and any access restrictions
  • Warn occupants and staff about the work
