Coloured sealant for Catford sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Keeping the joints sound

For the best life from the joints:

  • Put the colour reference on the finishes schedule
  • Use one colour standard across multi-site work
  • Keep the area clear while the sealant cures
  • Don’t let trades patch coloured joints with a random sealant

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

Make sure every contractor knows which sealant and colour are on the building file. That keeps new work in line with what’s there.

Coloured sealant in Catford, done properly

Matching to anodised or powder-coated frames is a common request. The frame colour is checked against the sealant’s standard range, and you approve the choice. If the range has no close colour, a paintable sealant can sometimes be overpainted, where the specification allows. The enquiries we see most involve colour changes after a rebrand or refit and dirty, discoloured joints in public areas, across powder-coated and anodised frames, natural stone and brick and office fit-out finishes. Whoever orders the work in Catford, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Buildings in a London area such as Catford rarely close for maintenance: offices with staff at their desks, shops trading below flats and receptions that can’t be roped off for long. We plan the joints floor by floor or unit by unit with the building manager, so areas stay in use, and where a brand finish matters, the sealant colour is agreed first.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:

  • Stopping sealant from ever changing colour outdoors
  • A guaranteed perfect match to every finish
  • Cleaning or repairing the surrounding finishes

Not sure which it is? You can call the office on 01277 525 020 or email the details over and we will tell you honestly.

What we seal

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

Cost factors for colour-matched joints

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

  • Travel to remote or island sites
  • Whether the work must be split into stages
  • Whether old sealant has to be cut out first
  • How accessible the joints are

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.

Before you send an enquiry

A few photographs plus some basic facts will normally do. It helps to include:

  • Anything awkward about access or site hours
  • The site address and postcode
  • The asbestos register, for older buildings
  • What the building is and how it’s used

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or send details through our quote form.

Catford: questions and answers

Can you work at a site such as Bell Green Retail Park, by Catford?

Yes. We cover Catford and the area around it, including industrial estates, business parks and retail parks such as Bell Green Retail Park. Photos and a short description are enough for a first look.

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

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

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

How a job runs

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. All of Greater London is in the ULEZ, and kerbside space in Catford can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We confirm the joint type and the product it needs.
  2. We compare the target colour with the colours available.
  3. The nearest colour is agreed, with a sample bead where needed.
  4. The existing bead comes out, then faces are cleaned and backed.
  5. We mask, seal and tool to a clean line.
  6. We remove the masking and walk the finished joints with you.

What we need from you

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

Quotes

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or email a schedule or drawings.

Sealant on show in Catford’s commercial buildings

The area within 2 miles of Catford holds a number of hotels. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter; work is planned so the hotel keeps trading. Four care or nursing homes sit less than 2 miles from Catford. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound, often in colours that suit the décor.

Catford is inside London’s ULEZ, as is the rest of Greater London; tell us about loading bays, goods lifts and parking when you send details. Units at retail parks like Bell Green Retail Park (1 mile south-west of Catford) change hands and get refitted, with new joints at every frontage.

Why act early in Catford

Agreeing the colour before work starts avoids paying twice. A sample takes little time compared with replacing joints in the wrong colour. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why us?

  • CHAS accredited contractor
  • A fixed quote before work starts
  • Over 20 years of commercial sealing
  • Coloured sealants to suit the setting, where available

Do you need coloured sealant in Catford?

On some projects the colour was never agreed, or a substitute product was used. It seals fine but catches the eye, so someone asks for it to be changed.

Any of the following is a good reason to get the joints checked over:

  • Marked sealant in hotel bathrooms
  • A run of joints in mismatched shades
  • Hotel refurbishments with a set colour scheme
  • Old colour-matched joints lifting at the edges

Offices and shops close to stations such as Catford Bridge station, 0.5 miles north-west of Catford, tend to be busy all day, so sealant work is planned around opening hours.

Before you book anyone

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • What site paperwork they can supply
  • The terms of the workmanship guarantee
  • What level of public liability insurance do they hold?
