About our coloured sealant in Gravesend

Architects, designers and brand teams often specify the sealant colour as carefully as the finishes around it. Most sealant types are made in a broad range of standard colours, so we check what the specified product is made in. An exact bespoke match can’t always be promised, so we talk you through the nearest colours. If you’re dealing with patch repairs in several different colours and smeared sealant on stone or joinery, we can help. Whoever orders the work in Gravesend, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

A job in a smaller place like Gravesend is usually a single building. We will want a full list and photos first, so the right products come on the day and nothing waits for a second trip.

Every job we finish is backed by a 12-month workmanship guarantee, in Gravesend as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Site staff or a sealant specialist?

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

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Why deal with it now?

A standard colour is quicker to source, though not always right. On visible work, the small extra effort of a colour from the product’s range pays off at handover. Halls, stores and units around places like Gravesend may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Why appoint us

  • One contact handling all your sites
  • CHAS accredited
  • Work to your specification and the manufacturer’s guidance
  • Standard and matched colours in many product ranges

See how commercial sealant jobs are priced or our accreditations and insurance.

After the work

Problems stay small when the joints are checked regularly. Specifically:

  • Agree the sealant colour early and write it into the specification
  • Protect fresh coloured sealant from dust and handling
  • Check a trial length in real light
  • Keep harsh solvents away from visible joints

Check visible joints during routine inspections. Look for splits, lifting edges and staining and deal with problems early.

Make sure every contractor knows which sealant and colour are on the building file. It stops mismatched repairs creeping in.

When it isn’t the sealant

Some faults sit outside our scope, and we say so rather than covering them up:

  • Paintable products in joints they aren’t suited to
  • Finishes that change colour from one area to another
  • Cleaning or repairing the surrounding finishes

If you are not sure, just give us a call on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

FAQs: Gravesend

Do you offer colour-matched sealant for buildings in Gravesend?

Yes, we can usually get close to most finishes from the product’s colour range. Available colours for the product are confirmed with the quote.

Will you take on work at estates like Hadham Industrial Estate, close to Gravesend?

Yes. Estates, retail parks and business parks around Gravesend, Hadham Industrial Estate among them, are all within reach. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Can staff carry on working while you’re here?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or email the details over. Include photographs or drawings if you have them.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

What sets the cost

Before we quote, we look at:

  • How much existing material needs removing
  • Working within restricted access windows
  • The site’s rules and procedures
  • Travel to remote or island sites

A quote for colour-matched joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Sending details for a quote

The more we know, the firmer the quote. When you get in touch, include:

  • Anything awkward about access or site hours
  • Whether the building will be occupied during the work
  • Your programme or deadline
  • Whether an asbestos survey exists

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to ring 01277 525 020 or send details through our quote form.

How a job runs

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area.

Advice

Coloured sealant in Gravesend: the local picture

The South East is one of the drier parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. Gravesend has two named business or industrial parks inside a 3-mile radius. Sites like these see regular refits, with shopfronts, offices and staff areas to seal; brand colours often come into it.

Shops and cafés around stations like Bishops Stortford station, 4.2 miles to the south-east of Gravesend, trade from early, so work is timed around them. If you have premises on more than one site, say at Hadham Industrial Estate and Oaks Industrial Park, one contractor and one quote can cover both. Industrial estates such as Hadham Industrial Estate, 1.6 miles to the south of Gravesend, have offices, trade counters and welfare areas whose sealant ages like any other building’s.
