About our coloured sealant in Willen

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. Let us know who signs off colour, and we will fit the sample into the programme. Most enquiries involve white or grey sealant that clashes with the finish and coloured joints that have cracked with movement, on hotel bathrooms and public areas, office fit-out finishes and natural stone and brick. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Willen, preparation and product choice get the time they need.

In and around smaller places such as Willen, the commercial buildings we’re asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Your questions answered

Does a hotel in Willen 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.

Is Willen too small for you to travel to?

No. Places such as Willen are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Can coloured sealant be used in washrooms and kitchens?

Yes. Sanitary silicones with anti-mould additives come in a range of colours too. We will confirm what’s available for the specified product and agree it with you.

Can staff carry on working while you’re here?

Usually, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

What do you charge?

Every job gets its own fixed quote. To get one, call 01277 525 020 or email the details over.

Can we approve the colour on site?

Yes. Tell us who approves colour and we will plan the sample into the programme so sign-off doesn’t hold up the work.

Do you take on colour-matched sealant for shop fits and multi-site roll-outs?

Yes. Shop fits, hotels and office fit-outs are a regular part of our work. Our area takes in Greater London, the South East and Scotland, so a consistent colour can run across several sites.

What Willen’s businesses ask us to seal

A 2-mile radius around Willen takes in a number of hotels. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter. Willen has at least three named business or industrial parks inside a 3-mile radius. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal; brand colours often come into it.

Offices and shops close to stations such as Milton Keynes Central station, 3.1 miles to the south-west of Willen, tend to be busy all day, so sealant work is planned around opening hours. Shopping centres and retail parks such as Central Milton Keynes Shopping Centre, 2 miles south-west of Willen, see a steady turnover of shop fits, each leaving joints where colour and finish matter.

Our process

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Willen can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First we agree which sealant type the joint 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. Edges are masked and the coloured sealant applied and tooled.
  6. Masking comes off and the work is checked with you.

What we need from you

  • For older buildings, check the asbestos register before work
  • Tell us what induction or permit system the site runs
  • Tell us which areas need to stay in use

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Advice

What sets the cost

Quotes vary with the job. Expect it to depend on:

  • The total length or number of joints
  • Joint width, depth and condition
  • Which sealant the job calls for
  • Whether the work must be split into stages

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • Rough lengths or quantities, or drawings if you have them
  • What the building is and how it’s used
  • Any dates the work must fit around
  • Whether an asbestos survey exists

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

Why deal with it now?

Matching new joints to the existing ones is easier when the whole run is done together. Piecemeal repairs over several years tend to drift in colour, and the patchwork effect grows. Older rural buildings around Willen move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What you get with us

  • CHAS accredited
  • A fixed quote before work starts
  • A range of standard colours, depending on the product
  • RAL and finish matching where the product range allows

See how commercial sealant jobs are priced or our accreditations.

When to call us in Willen

Joints repaired piecemeal often end up in several shades. Mixed repairs over time leave a run of mismatched joints across one elevation. Doing the full run in a single colour solves it.

Most enquiries start with one or more of the following:

  • Discoloured joints on a visible elevation
  • Stained or mouldy coloured joints in washrooms
  • Fit-outs with a sealant colour in the specification
  • Smeared sealant on stone or joinery

For tenants and agents on sites such as Cromwell Business Park, which lies north-east of Willen, office fit-outs, reception joints and window perimeters are the usual sealant work.

Comparing quotes

  • How long is the guarantee, and what does it include?
  • Whether primer will be used where the manufacturer specifies it
  • Which product they’ll use, and why it suits the joint
  • Whether old or failed sealant will be cut out, not overlaid

How to choose a sealant contractor

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • A guaranteed perfect match to every finish
  • Stopping sealant from ever changing colour outdoors
  • Finishes that change colour from one area to another

Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.
