Commercial sealant contractors in Flemings

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Our process

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Flemings are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. Site photographs, drawings or a visit tell us what’s there and how it has failed.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Tell staff and tenants when we’ll be in
  • Arrange parking or a loading space

Advice

About our commercial sealant contractors in Flemings

Most of the buildings we seal stay open while we’re there. Tell us your site hours and access windows and we’ll plan around them. That applies whether the building is an office, a shop, a hotel, a college or a care home. Most enquiries involve external beads that have gone brittle and cracked and messy, uneven beads from earlier work that let the building down, across movement joints in walls and floors, floor and threshold joints and kitchen worktops and splashbacks. A specialist sealant contractor works differently from a general builder: on jobs in Flemings, preparation and product choice get the time they need.

Multi-site clients with buildings in and around Flemings can put several sites on one programme, so standards and paperwork match across every site.

Business units in the countryside around places like Flemings are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently.

Work we carry out in Kent comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or send photos by email and we’ll come back to it.

Looking after the joints

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

  • Look at the sealant around anything that has been moved or replaced
  • Report cracked or peeling sealant early
  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Check sealant as part of routine building inspections

Our workmanship on each job is backed by a 12-month guarantee. File the handover note with the building records, and tell us if a joint we sealed gives trouble within that time.

Sealant installed at the same time normally fails in sequence. A few splits this year normally mean more next year so the whole run is worth inspecting. We’ll tell you which sealant joints need doing first and which can wait.

Should maintenance staff do it?

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

What affects the price in Flemings

To price the job, we consider:

  • Access and working height
  • Induction, permit and paperwork requirements
  • How much existing material needs removing
  • Phasing around occupants

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Details that help us quote

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

  • Asbestos survey details if the building is older
  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building
  • Any dates the work must fit around

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call the office on 01277 525 020 or send photos by email.

What Flemings’s businesses ask us to seal

Two named trading, business or retail sites lie within about 3 miles of Flemings. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal; brand colours often come into it. Central London is about 61 miles from Flemings. This part of the South East is dense with business parks and out-of-town offices. Multi-site occupiers here often want one sealant contractor across all their buildings.

Offices at parks like Birnham Farm Business Centre, 0.7 miles to the south-east of Flemings, have receptions, kitchens and glazed partitions where a tidy joint matters. Refits at hotels like The Lion Hotel (to the north of Flemings) bring joints at vanity tops, bars and reception desks that guests see every day. Offices and shops close to stations such as Sandwich station, 2.8 miles east of Flemings, tend to be busy all day, so sealant work is planned around opening hours.

Flemings is about 6 miles north-west of Deal, in Kent. We send applicators to Flemings for sealant joints, handled exactly as we handle every other area. Our Kent coverage takes in 931 places, from busy centres to rural villages. Our London page has more on work in that area, about 61 miles away.

FAQs: Flemings

Is a smaller place like Flemings outside your area?

No. Places such as Flemings are covered as much as the big towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Can you work at a site such as Birnham Farm Business Centre, by Flemings?

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

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Can you supply RAMS and insurance details?

Let us know your requirements when you ask for a price. For older buildings we will ask for the asbestos register, plus your site induction rules.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

How do we get a quote?

Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. For a fixed quote, send details through our quote form.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Surface by surface

Facade and cladding joints

Facade sealant failures can be hard to spot from the ground. Photos from a closer viewpoint help us price, with colours confirmed for the product chosen.

Movement joints in walls and floors

Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. When the seal fails, debris gets in and the joint stops working. The new sealant is chosen for the movement and, on floors, the traffic.

For managing agents and facilities managers

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Flemings can form part of a wider programme.
