Coloured sealant for commercial buildings in Nash Street

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. Tell us who needs to approve the colour and we’ll plan for it. If you have a run of joints in mismatched shades and weathered sealant that no longer matches, we can help. Looking for mastic applicators who cover Nash Street? We have been sealing commercial buildings since 2005.

Commercial sealant work around smaller places like Nash Street 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.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Nash Street can form part of a wider programme.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Should maintenance staff do it?

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Working on commercial sites near Nash Street

The South East is one of the drier parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. Less than 3 miles from Nash Street there are two named estates and business parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints; brand colours often come into it.

If you run a unit on an estate such as Bowes Industrial Centre, 2.5 miles south of Nash Street, the trade counter, offices and staff facilities have joints to look after as well as the warehouse. For premises near Meopham station, 0.7 miles south of Nash Street, footfall is part of the plan: work is phased so shops and offices keep trading.

Nash Street is about 3 miles south of Gravesend, in Kent. Nash Street sits inside our coverage and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else. Nash Street is one of 931 places in Kent on our list. For work in that direction, see our London page.

Different surfaces, different methods

Natural stone

Natural stone rarely has one colour, and the sealant has to work with that. A stone-compatible, neutral-cure sealant avoids staining.

Paintable sealants

Where no colour in the range is close, a paintable hybrid or PU sealant can sometimes be painted to match. It depends on movement and the specification because paint may crack where the joint moves.

From enquiry to sign-off

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. For a building around Nash Street, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  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. A short trial length can be approved before the full run on visible work.
  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

  • Send any specification or drawings in advance
  • Explain the parking and delivery arrangements
  • Tell us your opening times and when work is allowed

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Signs you need coloured sealant in Nash Street

Patch repairs in a different colour are a common problem. Different products and batches used over the years leave a patchwork along a shopfront. Doing the full run in a single colour solves it.

These are often picked up first by site or facilities staff:

  • A run of joints in mismatched shades
  • Colour changes after a rebrand or refit
  • Smeared sealant on stone or joinery
  • A bead that fights the cladding or frame colour

A business with units at Bowes Industrial Centre and Fawkham Business Park needn’t use two contractors for its sealant.

Comparing quotes

  • How the joint faces will be prepared and primed
  • Which product they’ll use, and why it suits the joint
  • How joint depth will be controlled
  • How the existing material will be dealt with

How to choose a sealant contractor

Nash Street: questions and answers

Do hotels near Nash Street have to close for sealant work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.

Will you take on work at estates like Bowes Industrial Centre, close to Nash Street?

Yes. Our area takes in Nash Street and its surroundings, with estates and business parks such as Bowes Industrial Centre included. A few photos and the unit address let us price the work.

Can coloured sealant be used in washrooms and kitchens?

Yes. Sanitary silicones with anti-mould additives come in a range of colours too. We check the colour range of the sanitary product specified before work starts.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Custom-mixed sealant colours
  • A colour that never alters with age
  • Finishes that change colour from one area to another

If in doubt, call 01277 525 020 or email the details over and we will say what we think.

Joints and surfaces we work on

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