Commercial sealant contractors across Furnace Green

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

Surface by surface

Commercial kitchens and tea points

Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. They’re degreased thoroughly before resealing.

Movement joints in walls and floors

Floor joints that take trolleys or forklifts need a tougher filler or sealant. The choice comes down to how much the joint moves and what runs over it, and tell you if the edges need repairing first.

About our commercial sealant contractors in Furnace Green

A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead and the joint depth is controlled with backing rod. If you’re dealing with mouldy silicone around WCs, urinals and vanity tops and leaks that seem to come through a sealant line, we can help, whatever the surface. Whoever orders the work in Furnace Green, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

The most common commercial job in Furnace Green is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

For a business in Furnace Green, it usually makes sense to put the sealant work into one visit: shopfront, washroom, kitchen and any external joints done together. That keeps travel and disruption down, and where colour matters on the frontage, we’ll confirm what’s available for the product.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Signs you need commercial sealant contractors in Furnace Green

A good share of the joints we inspect were topped up instead of being renewed. Fresh sealant won’t stick to the old bead underneath so it soon peels and traps moisture against the joint. Getting back to a clean joint then means removing every layer.

Common reasons buildings call us in:

  • Mouldy silicone around WCs, urinals and vanity tops
  • Earlier reseals applied straight onto the failed bead
  • Shrunken sealant along kitchen worktops and splashbacks
  • Smeared sealant across finishes from a rushed job

Offices at parks like Maidenbower Business Park, 0.9 miles to the north-east of Furnace Green, have receptions, kitchens and glazed partitions where a tidy joint matters.

What your quote should include

  • Whether their applicators hold CSCS cards
  • Will RAMS and insurance details be available?
  • Is the sealant right for the movement and the substrate?
  • What level of public liability insurance do they hold?

How to choose a sealant contractor

Working on commercial sites near Furnace Green

Furnace Green sits in one of the drier corners of the country, the South East. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings. Furnace Green lies roughly 28 miles out from central London. Business parks and retail centres are common around the capital’s motorway corridors. Multi-site occupiers here often want one sealant contractor across all their buildings.

For premises near Three Bridges station, which lies north of Furnace Green, footfall is part of the plan: work is phased so shops and offices keep trading. In hotels such as Europa Gatwick Hotel, which lies north-east of Furnace Green, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

Furnace Green is about 2 miles south-east of Crawley, in West Sussex. Our applicators travel to Furnace Green for work on sealant joints. Our West Sussex coverage takes in 373 places. There’s a separate page for Brighton, about 18 miles away.

FAQs: Furnace Green

Is Furnace Green too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you work at a site such as Maidenbower Business Park, by Furnace Green?

Yes, sites like Maidenbower Business Park are within our area, along with the rest of Furnace Green. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Can you supply RAMS and insurance details?

We will confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We are CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.

Do you work for facilities managers and managing agents?

Yes. FMs, managing agents and landlords are among our regular clients, alongside main contractors. Tell us how you issue work and we’ll fit in.

Is it OK to apply fresh sealant over existing beads?

Full removal is part of every quote. A bead laid on old silicone peels away.

Is your work guaranteed?

It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.

What do you need from us to quote?

Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. To get a fixed price, send details through our quote form, or phone or email us.

What happens if it’s left?

A cheaper quote sometimes means the old bead stays in. New sealant laid on old silicone has nothing to bond to, so it peels. Every quote we give includes full removal and preparation. Small buildings around Furnace Green suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What you get with us

  • Fully insured, including public liability cover
  • Products installed to the manufacturer’s instructions
  • Constructionline member for supplier checks
  • 12 months’ guarantee on every job

How a job runs

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. What matters most for a job in Furnace Green is a clear list of what needs doing, so send photos of each area. You’ll then get a fixed price for the work.

  1. We start with the evidence: photographs, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

Before we start on site

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

  • Location, for remote and island sites
  • The size and state of each joint
  • The site’s rules and procedures
  • Any access equipment needed

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What to include in your enquiry

We can often quote from photographs and a few details. Please tell us:

  • Clear photographs of the problem areas
  • When you need the work done
  • Anything awkward about access or site hours
  • Where the site is, with the postcode

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or use the quote form.

General trades versus a specialist

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
