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

When something else is needed

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Paint over sealant on joints that move too much
  • Colour variation across natural stone or brick that no single shade can match
  • A colour that never alters with age

Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we will tell you honestly.

Where we work in Chorleywood

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

How we handle coloured sealant in Chorleywood

Natural materials vary across a single elevation: a stone or brick facade shifts in tone from one area to the next. We choose a colour that reads well across the surface rather than chasing one spot, with a sample on site if colour is critical. Most enquiries involve marked sealant in hotel bathrooms and old sealant that has yellowed, darkened or faded, on office fit-out finishes, natural stone and brick and cladding panels. A specialist sealant contractor works differently from a general builder: on jobs in Chorleywood, preparation and product choice get the time they need.

In a smaller place such as Chorleywood, commercial buildings are typically a mix of shops, a pub or café, a school, a surgery and perhaps a few business units. Each job is modest, yet a joint in a small café needs the same cutting out, cleaning and sealing as one in a city office.

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

Commercial premises in Chorleywood

At about 20 miles from central London, Chorleywood is within reach of the capital. Business parks and retail centres are common around the capital’s motorway corridors. Firms with branches across the South East can use one contractor for every site. There are four care or nursing homes within about 2 miles of Chorleywood. Care settings have kitchens, lounges and corridors where joints need to be neat and easy to clean, often in colours that suit the décor.

Sites a few miles apart, such as Woodcock Hill Industrial Estate and Peerglow Industrial Estate, can share one programme and one point of contact. For premises near Chorleywood station, which lies west of Chorleywood, footfall is part of the plan: work is phased so shops and offices keep trading. Industrial estates such as Woodcock Hill Industrial Estate, 2.4 miles to the south-east of Chorleywood, have offices, trade counters and welfare areas whose sealant ages like any other building’s.

From enquiry to sign-off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking a day for a modest shop fit, and longer for a full building or several floors. Several jobs near Chorleywood can be grouped on one trip. Mention the building’s opening times and we will work within them.

  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. We cut out the existing bead, clean and set the depth.
  5. We mask, seal and tool to a clean line.
  6. We remove the masking and walk the finished joints with you.

Getting the site ready

  • Let us know about inductions and permits
  • Make sure the joints can be reached
  • Tell us your opening times and when work is allowed

Owners, agents and contractors

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Why act early in Chorleywood

Standard white or grey sealant is cheaper to stock, but it doesn’t always suit the finish. On visible work, the small extra effort of a colour from the product’s range pays off at handover. In a smaller place such as Chorleywood, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Maintenance after handover

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Put the colour reference on the finishes schedule
  • Plan full-run reseals on visible elevations
  • Look at the cured colour before the full run
  • Clean coloured joints with mild products

If other trades disturb a coloured joint, ask them to tell you rather than patch it. A mismatched repair stands out, so it is better to reseal the section properly.

Plan resealing of visible joints before they look tired. Replacing them on a schedule keeps finishes looking right across the building.

Different surfaces, different methods

Paintable sealants

Paintable sealants suit internal, low-movement joints best. We will tell you if a joint needs a non-paintable product.

Shop-fit and joinery finishes

Shop fits bring laminate, timber, metal and stone together, each with its own colour. We choose sealant colours that suit each junction as agreed with the designer.
