About our commercial sealant contractors in Goathurst Common

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed. Anything suspect is left alone until it has been tested, and we don’t remove asbestos-containing materials ourselves. The enquiries we see most involve black mould through washroom sealant that won’t clean off and earlier reseals applied straight onto the failed bead, across movement joints in walls and floors, washrooms and tea points and kitchen worktops and splashbacks. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Goathurst Common, preparation and product choice get the time they need.

We price commercial jobs in Goathurst Common from photographs, drawings or a site visit, with the scope listed so everyone knows what’s included.

Rural business units near smaller places such as Goathurst Common are frequently converted agricultural buildings. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Building owners and managing agents use us on everything from one building to a spread of sites around Goathurst Common. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Why it’s worth doing now in Goathurst Common

Fixing joints complaint by complaint is a costly way to manage sealant. A planned programme groups work by building or area, cuts repeat visits and gives you a budget figure. We can help you prioritise, starting with the joints most likely to let water in. Converted and older buildings near places like Goathurst Common tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

Why appoint us

  • Colours chosen to suit frames, cladding or finishes where possible
  • Our applicators hold CSCS cards
  • Failed material removed, not covered up
  • 12-month guarantee on workmanship

Take a look at how commercial sealant jobs are priced and how we’re accredited.

What the job involves on each surface

Fire-rated seals where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. The design and sign-off of fire stopping belong to the designer and building control.

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Photos from a closer viewpoint help us price.

How a job runs

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Jobs in and around smaller places like Goathurst Common are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. Send details through our quote form, or ask for a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Where parts of the building must stay open, the work is phased.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Before we start on site

  • Flag any permit to work we will need
  • Tell us which areas need to stay in use
  • Arrange parking or a loading space

Quoting for work in Goathurst Common

Quotes vary with the job. It mainly depends on:

  • Access and working height
  • Joint width, depth and condition
  • Whether the work must be split into stages
  • The site’s rules and procedures

A quote for sealant joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

Sending details for a quote

Good information means a firmer quote. When you get in touch, include:

  • The type of building and who uses it
  • Photos of the joints, close up and from further back
  • Anything awkward about access or site hours
  • The asbestos register, for older buildings

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

What we’re called out for in Goathurst Common

A split down the middle of the bead tells a different story. Normally the movement was too much for the sealant chosen because the bead was too thin, the joint over-stretched or the movement class wrong. Replacing it like for like rarely holds.

Common reasons buildings call us in:

  • Sanitary sealant that has gone black and patchy
  • Untidy joints in a reception, shop floor or lobby
  • Layers of sealant, all of them failing
  • Frame sealant that has cracked, shrunk or pulled away

Shops and cafés around stations like Sevenoaks station, 2.5 miles north-east of Goathurst Common, trade from early, so work is timed around them.

What your quote should include

  • What the guarantee covers, and for how long
  • How joint depth will be controlled
  • Do they follow the manufacturer’s priming guidance?
  • Are they CHAS accredited or on Constructionline?

Common questions from Goathurst Common clients

Will you take on work at estates like Salters Heath Business Centre, close to Goathurst Common?

Yes. We cover Goathurst Common and the area around it, including industrial estates, business parks and retail parks such as Salters Heath Business Centre. Send details of the unit and the work through our quote form for a quick quote.

Do you offer colour-matched sealant for buildings in Goathurst Common?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. The quote lists the colours the product is made in.

Is failed sealant stripped out, or sealed over?

Removal of the failed sealant is always part of the job. New sealant can’t grip the old bead, so laying over it never lasts, and the faces are brought back to sound, dry material before resealing.

Can areas stay open during the work?

It’s mostly about sequence: areas are phased, access windows agreed and enough washrooms or entrances left in use. Let us know what can’t close and we will work around it.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

Is your work guaranteed?

The work is guaranteed for 12 months. Should anything we did fail within that period, let us know.

Does weather matter for sealant work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
