About our commercial sealant contractors in Broomfield

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, then both faces are cleaned back to sound, dry material with no dust or grease on them. 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. Site teams most often ask us about layers of sealant, all of them failing and untidy joints in a reception, shop floor or lobby, across external facade joints, floor and threshold joints and kitchen worktops and splashbacks. Whether you call it commercial sealant work, mastic application or joint sealing, in Broomfield it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

On a typical commercial building in Broomfield, the joints that fail first are the hardest-worked ones: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

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

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Should maintenance staff do it?

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Commercial premises in Broomfield

Broomfield lies roughly 36 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. Rainfall across the South East, Broomfield included, is lower than in many parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up.

Shops and cafés around stations like Hollingbourne station (1.6 miles north of Broomfield) trade from early, so work is timed around them. Offices at parks like Roebuck Business Park, 1.6 miles east of Broomfield, have receptions, kitchens and glazed partitions where a tidy joint matters.

Broomfield is about 5 miles east of Maidstone, in Kent. Broomfield sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Broomfield is one of 931 places we cover in Kent for sealant joints. We also cover London, some 36 miles away.

FAQs: Broomfield

Can you supply sealant in our brand colour for a site in Broomfield?

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.

Can you work at a site such as Roebuck Business Park, by Broomfield?

Yes. Estates, retail parks and business parks around Broomfield, Roebuck Business Park among them, are all within reach. A few photos and the unit address let us price the work.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

Do you check for asbestos before removing sealant?

On older buildings, our first request is the asbestos survey. The duty to manage asbestos sits with the dutyholder, and we don’t remove asbestos-containing materials.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

How do we get a quote?

Start with whatever information is to hand. We follow up with questions or a visit where needed.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Aftercare for building managers

For the best life from the joints:

  • Keep abrasive pads and scrapers off resealed joints
  • Keep barriers up until the new sealant has cured
  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Add sealant to the planned maintenance inspection list

New joints need their full cure time before they take water, cleaning or traffic. Cure time varies with the product, conditions and depth of the joint, so we confirm it for each area at handover. Keeping signs or barriers up until then protects the finish.

Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.

Why deal with it now?

Some managers wait for a fit-out before touching the mastic. For internal joints that are only cosmetic, that can make sense, but external and wet-area joints that already leak shouldn’t wait. Splitting the scope into now and later is often the sensible compromise. Older rural buildings around Broomfield move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Why us?

  • Specification-led, product-correct work
  • Joints cleaned back to sound surfaces
  • Colours confirmed for the specified product
  • Public liability insurance in place

How the quote is worked out

To price the job, we consider:

  • Phasing around occupants
  • Whether old sealant has to be cut out first
  • Joint width, depth and condition
  • Quantities, in metres or numbers

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

What to include in your enquiry

We can often quote from photos and a few details. It helps to include:

  • How the joints are reached, and at what height
  • The site address and postcode
  • What the building is and how it’s used
  • Photos of the joints, close up and from further back

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

From enquiry to sign-off

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Smaller jobs around Broomfield can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. First, details reach us through the quote form or 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. Old sealant is cut out completely, never sealed over.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.

Preparing the site

  • Have the specification and drawings to hand
  • Clear stock, furniture or equipment away from the joints
  • Send asbestos survey details if the building is pre-2000

Getting a fixed quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or email a schedule or drawings.

How the job changes by surface

Commercial kitchens and tea points

Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. Proper degreasing comes before any new sealant, and a hygienic or food-safe sealant is used where food contact is possible.

Facade and cladding joints

Facade joints move every day as panels warm and cool. They need a sealant with the right movement capability, laid at the right depth. Access, such as scaffold already up, is agreed before the price is fixed.
