Floor joint sealing near Great Missenden

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

How we handle floor joint sealing in Great Missenden

We have been sealing commercial joints since 2005. Our CSCS-carded applicators follow your site induction and rules, and we are CHAS accredited and a Constructionline member, with public liability insurance in place. Completed joints come with a 12-month guarantee on our workmanship. We work on retail and showroom floors, saw-cut induced joints and construction joints, and what we are called in for most is flexible sealant torn out by wheels and failing joints at loading bays and dock doors. For commercial sealant work in Great Missenden, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Jobs around smaller places like Great Missenden are planned so the whole job is done in one visit. Note joint widths and the traffic that uses them, and we’ll take it from there.

A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or email drawings and photos and we’ll come back to it.

Work for main contractors and building owners

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’ll confirm them with the quote.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

What we’re called out for in Great Missenden

A slab keeps shrinking for a long time after it is cast, and the saw cuts are there so it cracks in straight, controlled lines. As the panels contract, the joints widen, and a filler placed early can part company with one face.

These are often picked up first by site or facilities staff:

  • A gap opening alongside old joint filler
  • Broken arrises where pallet trucks cross
  • Open saw cuts full of debris
  • Grimy joint lines spoiling a showroom floor

Campuses like Buckinghamshire New University (3 miles south-east of Great Missenden) mix old and new buildings, with movement joints wherever they meet.

What to look for in a quote

  • Whether their applicators hold CSCS cards
  • Their pre-qualification and accreditations
  • How they handle RAMS and site documents
  • How they’ll work around occupants

Choosing a commercial sealant contractor

What we can’t put right

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

  • A floor that is out of level for the racking or trucks
  • Spalled arrises, which need an edge repair first
  • A floor that rocks at the joints, which needs a structural fix

If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think before you book.

What we seal

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

How a job runs

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. If others near Great Missenden need work, visits can be combined. A fixed quote is given before anything starts.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. The treatment and the zones are set out in a fixed quote.
  3. Old fill and packed debris come out until both faces are sound.
  4. We extract the dust and prime the faces if the product needs it.
  5. The joint is filled to its specified depth and trimmed level.
  6. Zones reopen once cured and the work moves on.

Preparing the site

  • Point out any areas we must not close
  • Flag any permit to work we’ll need
  • Have the specification and drawings to hand

What happens if it’s left?

Open joints are where dirt collects, out of reach of the floor cleaner. Where the floor is on show or needs to be kept clean, that is a problem. Flush, filled joints leave nothing for cleaners to dig out. One visit to deal with every failing joint makes more sense than several trips to a place like Great Missenden, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Pricing floor joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Traffic, movement and joints around Great Missenden

Great Missenden is about 30 miles from central London. Warehousing clusters around the motorways that ring and radiate from London. Great Missenden sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in.

Hospital campuses such as The Chiltern Hospital (to the south-east of Great Missenden) grow in stages, leaving movement joints wherever new blocks meet old. In a school such as Great Missenden CofE Combined School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Great Missenden is about 4 miles west of Chesham, in Buckinghamshire.

How the quote is worked out

These are the things that shape the price:

  • Whether the work must be split into stages
  • Backing rod, priming and other preparation
  • Distance, for remote addresses
  • How much there is to seal

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What we need to price the job

A few photographs plus some basic facts will normally do. Please tell us:

  • Access details, including height
  • The site address and postcode
  • What the building is and how it’s used
  • When you need the work done

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 will fill any gaps with a visit.

Questions we’re asked in Great Missenden

Is Great Missenden too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Must our site in Great Missenden stop work while the joints are done?

Typically not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Are you fully insured?

Yes. Mastic Doctor is fully insured, public liability included.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

How long before trucks can use the joints?

Cure times vary with the product and the conditions. You’ll get a reopening time for each area when we agree the phasing.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
