About our coloured sealant in Kensal Rise

Window, door and shopfront frames in RAL finishes often need a sealant to suit. We compare the RAL reference with the colours made for the specified sealant, and the nearest option is agreed with you. Where nothing in the range is close enough, a paintable hybrid or PU sealant may be an alternative, if the joint and specification allow. If you have poorly tooled joints on visible finishes and patch repairs in several different colours, we can help, whatever the surface. One point of contact handles commercial sealant work in Kensal Rise from the first photographs to the final walk-round, whether it’s one building or several.

For managing agents and FMs looking after premises in Kensal Rise, access is usually the first question: 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.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When to call us in Kensal Rise

On some projects the colour was never agreed, or a substitute product was used. The joint may work perfectly but look out of place, so someone asks for it to be changed.

What tends to prompt an enquiry:

  • Old sealant that has yellowed, darkened or faded
  • Patch repairs in several different colours
  • Joints that need to match a new RAL frame colour
  • White or grey sealant that clashes with the finish

In hotels such as Igar Hotel, 0.5 miles to the north-east of Kensal Rise, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

What your quote should include

  • Health and safety accreditation such as CHAS
  • Will failed sealant be removed rather than covered?
  • How they’ll work around occupants
  • Their approach to joint depth and backing

How to choose a sealant contractor

What affects the price in Kensal Rise

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Which sealant the job calls for
  • Phasing around occupants
  • The size and state of each joint
  • Site requirements such as inductions and permits

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

What we need to price the job

To price the job accurately, we need a clear picture of the site. Send us:

  • The asbestos register, for older buildings
  • Clear photographs of the problem areas
  • Specification clauses that apply
  • Where the site is, with the postcode

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or use the quote form if you’d rather talk the job through.

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Putting right a botched joint often costs more than sealing it well at the start, 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.

How a job runs

We begin with a short walk round with whoever looks after the building, 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. For a job in Kensal Rise, access comes first. Send the building rules and access times with your enquiry.

  1. The sealant type is chosen for the joint first, then the 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

  • Let us know about inductions and permits
  • Move anything stored against the joints
  • Agree which areas must stay open

Your questions answered

Must a hotel around Kensal Rise close while you work?

Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we’ll plan around them.

Can you work at a site such as The Quadrant Business Centre, by Kensal Rise?

Yes. Our area takes in Kensal Rise 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.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Can staff carry on working while you are here?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

Aftercare for building managers

After handover, a little attention goes a long way:

  • Standardise colours across a portfolio
  • Put the colour reference on the finishes schedule
  • Keep the colour details for future repairs
  • Don’t let trades patch coloured joints with a random sealant

Colours can soften with light and weathering. Some fading is part of normal ageing outdoors, and resealing restores the look when the time comes.

Ask for a trial bead on high-profile areas. Seeing the cured colour in place avoids surprises.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • A guaranteed perfect match to every finish
  • Overpainting a joint that needs a non-paintable product
  • Colour variation across natural stone or brick that no single shade can match

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.

What we seal

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