Coloured sealant for commercial buildings in Borstal

Coloured sealant work ranges from a new shop fit to replacing failed joints on an existing building on sites across Medway. On resealing, matching the existing colour is often as important as the seal itself, particularly where the building’s look matters. If you have old sealant that has yellowed, darkened or faded and smeared sealant on stone or joinery, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Borstal from the first photos to the final walk-round, for single jobs and planned programmes alike.

Small businesses near places like Borstal frequently occupy converted farm buildings. Those conversions put new frames and partitions against old brick, stone or timber, so each joint needs a product chosen for both surfaces.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Owners, agents and contractors

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Borstal can form part of a wider programme.

How a job runs

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a site in Borstal, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.

  1. First we agree which sealant type the joint needs.
  2. Your RAL reference, sample or photo is checked against that product’s colours.
  3. You approve the colour, on site if it’s critical.
  4. We cut out the existing bead, clean and set the depth.
  5. We mask, seal and tool to a clean line.
  6. Masking comes off and the work is checked with you.

Preparing the site

  • Move anything stored against the joints
  • Arrange parking or a loading space
  • Send your site hours and access windows

FAQs: Borstal

Is Borstal too small for you to travel to?

Not at all. Borstal is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Will our hotel in Borstal need to close for the work?

Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.

Is coloured sealant weaker than white?

The colour doesn’t change what kind of sealant it is. Preparation, backing and tooling are what make it last.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Can the building stay open while you work?

In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

What will the job cost?

It depends on the job: quantities, access, the product and any phasing. Call for a quote.

Can you work to a RAL reference?

Yes. RAL references are a common way to specify sealant colour. We’ll confirm the colours available for the specified product and agree the choice with you.

Commercial premises in Borstal

A good number of hotels sit less than 2 miles from Borstal. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme, with rooms done in turn while the rest stay let. The 3 miles around Borstal take in at least three named trading estates, business parks or retail parks. Sites like these see regular refits, with shopfronts, offices and staff areas to seal.

A hotel such as The Dickens Hotel (to the north-east of Borstal) shows how much sealant a hospitality building has on show, from bathroom joints to the bar. If you look after units at a retail site such as Strood Retail Park, 1.4 miles north of Borstal, shopfront perimeters and shop-fit joints are where a matched colour shows.

What we are called out for in Borstal

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

Common reasons buildings call us in:

  • Discoloured joints on a visible elevation
  • Sealant that no longer suits recoated frames
  • Fit-outs with a sealant colour in the specification
  • A bead that fights the cladding or frame colour

A business with units at Strood Retail Park and Castle View Business Centre needn’t use two contractors for its sealant.

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • Can the work be phased to keep areas open?
  • What the guarantee covers, and for how long
  • Health and safety accreditation such as CHAS

Questions to ask before you appoint anyone

When it isn’t the sealant

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

  • Preventing all fading from sunlight and weathering
  • Exact bespoke colour matches beyond the product’s range
  • Restoring stained stone or masonry next to old sealant

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

Where we work in Borstal

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

Cost factors for colour-matched joints

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Location, for remote and island sites
  • How accessible the joints are
  • Induction, permit and paperwork requirements
  • Quantities, in metres or numbers

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Details that help us quote

A good diagnosis starts with the right details. Tell us:

  • Where the site is, with the postcode
  • Your programme or deadline
  • How the joints are reached, and at what height
  • Asbestos survey details if the building is older

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
