Floor joint sealing in Lee Gate

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

Aftercare for building managers

A few simple habits keep the new joints working:

  • Treat loading bay joints first if they’re failing
  • Remind operators to lift rather than drag
  • Clear packed debris from open joints regularly
  • Photograph any joint that starts to chip

Once cured, the joints get cleaned along with the slab. If you use strong chemicals or hot-water washing, mention it when we quote so we choose something that tolerates them.

Every day an open joint stays full of grit, the edges take more punishment. Getting it filled stops the damage before it becomes a repair.

Floor joint sealing for commercial buildings in Lee Gate

We diagnose the floor first rather than guessing at a product: how wide the joints are, signs of ongoing movement, the wheel types crossing them and the state of the arrises. From that we choose between a semi-rigid filler and a more flexible sealant, area by area where it needs to be. We work on loading bays, saw-cut induced joints and joints along racking aisles, and the usual reasons a site gets in touch are dock area joints that have failed first and grimy joint lines spoiling a showroom floor. Searching for sealant specialists in Lee Gate? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Halls, schools and small commercial buildings near places like Lee Gate have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or use the quote form and we will come back to it.

When to call us in Lee Gate

Joints near dock doors see colder air, rain blown in and water off vehicles on top of the heaviest turning movements. That is usually where joint failure starts.

Site and facilities staff are often the first to spot these:

  • Chipped and spalling edges along forklift routes
  • Scruffy, dirty joint lines on a shop or showroom floor
  • Failing joints at loading bays and dock doors
  • Flexible sealant torn out by wheels

A campus such as Buckinghamshire New University, 4.7 miles south-east of Lee Gate, has long runs of movement joint in its buildings, decks and paving.

Cost factors for floor joints

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Working within restricted access windows
  • Location, for remote and island sites
  • Joint width, depth and condition
  • How accessible the joints are

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Details that help us quote

To price the job accurately, we need to understand the site. Useful things to include:

  • The type of building and who uses it
  • Whether an asbestos survey exists
  • The site address and postcode
  • Photos of the joints, close up and from further back

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or email drawings and photos.

Slabs, ramps and loading bays in Lee Gate

Lee Gate lies roughly 31 miles out from central London. The roads out of London are lined with trade parks and distribution sheds. Lee Gate is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint.

Schools like Lee Common Church of England School often have long brick elevations with movement joints that age quietly. Office parks like Station Approach Business Park (to the north-west of Lee Gate) have decks, ramps and clad elevations whose joints take movement every day.

Questions about Lee Gate

Is a smaller place like Lee Gate outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can you take on a job at a hospital such as Chiltern Hospital?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

How long before trucks can use the joints?

The wait is set by the product’s cure time, and cold floors slow it down. Phasing is planned with that in mind.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Are you insured?

Yes. We are fully insured, including public liability cover.

Can the sealant be colour-matched?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

Our process

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Jobs in and around smaller places like Lee Gate are normally planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. You receive a fixed quote showing products and phasing.
  3. Each joint is cut or routed back to clean, sound concrete.
  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. We hand each phase back when it can take traffic.

What we need from you

  • Let building users know which areas are affected
  • Share your working hours and any access restrictions
  • Arrange parking or a loading space

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Why act early in Lee Gate

Duct tape or a general builders’ sealant can seem to buy some time. Neither is made to carry wheels and traffic soon pulls it out. A product chosen for the traffic and movement does the job once. Older rural buildings around Lee Gate move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
