About our coloured sealant in Stonor

We take on colour-matched work across new fit-outs, refurbishments and resealing of existing joints on sites in Stonor. When replacing old joints, the new colour normally has to match what’s already there, especially on a listed or high-profile elevation. Site teams most often ask us about poorly tooled joints on visible finishes and fit-outs with a sealant colour in the specification, on office fit-out finishes, shop-fit joinery and counters and natural stone and brick. Most enquiries from Stonor start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Commercial sealant work around smaller places like Stonor tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Commercial clients in Stonor

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

When to call us in Stonor

Internal joints can stain from cleaning products, spills or mould. Mould that has grown into sealant normally can’t be cleaned out, so the joint is replaced.

Most enquiries start with something like this:

  • A bead that fights the cladding or frame colour
  • Colour changes after a rebrand or refit
  • Old colour-matched joints lifting at the edges
  • Old sealant that has yellowed, darkened or faded

A lasting commercial joint around Stonor begins with the old bead fully out and the faces clean and dry.

Questions to ask before you book

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • What level of public liability insurance do they hold?
  • Whether old or failed sealant will be cut out, not overlaid
  • Which product they’ll use, and why it suits the joint

Our contractor checklist

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. Smaller jobs around Stonor can be grouped with others nearby. A fixed quote is given before anything starts.

  1. The sealant type is chosen for the joint first, then the colour.
  2. We compare your RAL reference or sample with the colours made for that sealant.
  3. Where colour is critical, a sample bead can be agreed in a discreet spot.
  4. We remove the existing bead, clean the faces and set the depth.
  5. The coloured sealant is applied and tooled with clean, masked edges.

What we need from you

  • Tell us which areas need to stay in use
  • Have the specification and drawings to hand
  • Let building users know which areas are affected

Questions about Stonor

Is a smaller place like Stonor outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Can the sealant on our Stonor premises match the finishes?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Send colour references or photographs and we’ll confirm what’s available for the product.

Does the weather affect the work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

How long does a job like this take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Surface by surface

Brick and masonry

Brickwork joints normally look best in a colour close to the mortar or brick. We choose a suitable shade from the product’s range.

Natural stone

Stone has variation, so the aim is a colour that sits naturally against it. A stone-safe neutral-cure product is used in the closest available colour.

Commercial premises in Stonor

Rainfall across the South East, Stonor included, is lower than in many parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. Central London is about 37 miles from Stonor. Business parks and retail centres are common around the capital’s motorway corridors. Multi-site occupiers here often want one sealant contractor across all their buildings.

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Custom-mixed sealant colours
  • Stopping sealant from ever changing colour outdoors
  • Materials with mixed tones that defy a single match

If you are not sure, just call 01277 525 020 or email us and we’ll give you a straight answer.

What we seal

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

How the quote is worked out

To price the job, we consider:

  • Joint width, depth and condition
  • Removal of failed or old sealant
  • Working within restricted access windows
  • How accessible the joints are

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

What we need to price the job

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Any dates the work must fit around
  • The asbestos register, for older buildings
  • Where the site is, with the postcode
  • Access details, including height

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
