Coloured sealant across Radley Green

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

Doing it in-house

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.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

About our coloured sealant in Radley Green

A coloured bead has to perform like any other sealant. Each joint is cleaned, backed to depth and tooled firmly onto both faces, exactly as for a standard colour. Clean masking and steady tooling give the sharp lines colour work needs. We work on shop-fit joinery and counters, office fit-out finishes and hotel bathrooms and public areas, and the failures we’re asked to look at most are a run of joints in mismatched shades and marked sealant in hotel bathrooms. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Radley Green, that means joint design, primers and backing rod as standard.

Work in smaller places such as Radley Green tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Questions about Radley Green

Is Radley Green off your patch?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Which documents can you supply for work in Radley Green?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Will sunlight affect the sealant colour?

Some change is normal outdoors. UV and grime can soften or alter the colour.

Will the sealant be an exact match to our finish?

No. We can’t promise an exact custom match. Sealants come in a wide range of standard colours, and we’ll confirm the colours available for the specified product.

Can you work to a RAL reference?

Yes. Many specifications give the sealant colour as a RAL number. We will confirm the colours available for the specified product.

Can staff carry on working while you’re here?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

What the job involves on each surface

Natural stone

Sandstone, limestone and granite each have distinct tones. Colour is agreed on site where possible before the full run.

Brick and masonry

Brickwork joints normally look best in a colour close to the mortar or brick. The nearest colour in the range is agreed with you for the elevation.

Why deal with it now?

Standard white or grey sealant is cheaper to stock, but it doesn’t always suit the finish. Where joints are on show, choosing a better colour is typically worth it at handover. Around Radley Green, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What you get with us

  • Colour agreed before work starts
  • Fixed quotes based on photographs, drawings or a visit
  • Matching to RAL references, product permitting
  • A range of standard colours, depending on the product

Read our cost guide or how we’re accredited.

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Keep harsh solvents away from visible joints
  • Avoid piecemeal repairs on coloured joints
  • Note which sealant colour was used where
  • Look at the cured colour before the full run

If other trades disturb a coloured joint, ask them to tell you rather than patch it. Wrong-colour patches are obvious.

Share the colour reference with anyone working on the finishes. That keeps new work in line with what’s there.

Sealant on show in Radley Green’s commercial buildings

Radley Green lies roughly 25 miles out from central London. The commuter belt holds a great many offices, retail parks and business parks. Firms with branches across the South East can use one contractor for every site. The South East is one of the drier parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

For premises near Ingatestone station, 4.2 miles south of Radley Green, footfall is part of the plan: work is phased so shops and offices keep trading. For any commercial premises in Radley Green, a lasting joint depends on full removal of the old sealant and clean, dry faces.

Radley Green is about 6 miles west of Chelmsford, in Essex. We cover commercial sites throughout Radley Green. Across Essex, 644 places are covered, Radley Green among them. Our London page has more on work in that area, about 25 miles away.

Our process

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. For work around Radley Green, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  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. The agreed colour is installed and tooled neatly.

What we need from you

  • For older buildings, check the asbestos register before work
  • Explain the parking and delivery arrangements
  • Point out any areas we must not close

Get a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
