Floor joint sealing near Cobham

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

For managing agents and facilities managers

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Cobham can form part of a wider programme.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

How we handle floor joint sealing in Cobham

Some joints reach us with their edges already broken. Filling against a crumbled arris won’t hold for long, so we’ll tell you if the joint edges need repairing first and explain how it affects the programme. If you have drivers complaining about joints on a route and old filler gone hard, cracked or loose, we can help, on loading bays, retail and showroom floors and construction joints alike. Facilities teams, main contractors and managing agents in Cobham tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Smaller community and commercial buildings around Cobham have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

FAQs: Cobham

Is a smaller place like Cobham outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Does your area include sites such as Bowes Industrial Centre, near Cobham?

Yes. Our area takes in Cobham and its surroundings, with estates and business parks such as Bowes Industrial Centre included. To start, just give us a call on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

What do you need from us to quote?

Send details through our quote form or by email, with the traffic on each area. We then send a fixed quote with the product and phasing set out.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

How long does a job like this take?

The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.

Do you use semi-rigid filler or flexible sealant on floor joints?

We decide joint by joint. Where hard wheels cross, a semi-rigid filler is usually right, and movement joints or perimeters need something flexible. The quote sets out what goes where.

When something else is needed

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • A floor that rocks at the joints, which needs a structural fix
  • Uneven floors that need grinding or levelling
  • A failing floor coating, which is a flooring contractor’s job

Not sure which it is? You can call the office on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Surfaces we seal

  • Retail and showroom floors
  • Joints along racking aisles
  • Construction joints
  • Saw-cut induced joints
  • Forklift and pallet-truck routes
  • Loading bays

Why act early in Cobham

Waiting for a site-wide shutdown often means the joints keep getting worse. Zone by zone, the worst aisles can be dealt with now and the remainder follows on a plan that suits you. Older rural buildings around Cobham move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Why clients in Cobham choose us

  • One phone line for London, the South East and Scotland
  • Fully insured, including public liability cover
  • Work to your specification and the manufacturer’s guidance
  • 12 months’ guarantee on every job

From enquiry to sign-off

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For work around Cobham, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
  2. The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
  3. Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
  4. Dust is extracted from the joint and primer applied where the manufacturer specifies it.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. We tell you when each zone can carry trucks again and move on to the next.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Warn occupants and staff about the work
  • Share your working hours and any access restrictions

Getting a fixed quote

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Floor joint sealing around Cobham: how the place shapes the job

Rainfall across the South East, Cobham included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open. Cobham is about 23 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift.

Schools like Cobham Primary School often have long brick elevations with movement joints that age quietly. For estates staff at a university like University for the Creative Arts - Rochester (4.9 miles east of Cobham), building and paving joints are part of the planned maintenance list. Warehouse floors on estates like Bowes Industrial Centre, 3 miles to the south-west of Cobham, carry pallet trucks and forklifts over every saw-cut joint.

Site staff or a sealant specialist?

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
