Expansion joint sealing in Navestock Common

A movement joint only works while its seal does. Once it fails, water, grit and debris get in. Resealing at the first signs of failure is far cheaper than repairing the material either side. If you have leaks through car park deck joints onto the level below and brittle, chalky sealant on external joints, we can help, on car park decks and ramps, blockwork control joints and brickwork movement joints alike. Searching for sealant specialists in Navestock Common? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

In and around smaller places like Navestock Common, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Common problems we fix in Navestock Common

Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, usually means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way.

If one of these sounds familiar, it’s time for a closer look:

  • Previous reseals laid over old sealant
  • Torn sealant in brick or block movement joints
  • Chipped joint edges on forklift routes
  • Damp inside where a wall movement joint has failed

Schools such as Drapers' Academy have movement joints in their walls and floors that are easy to overlook.

Questions to ask before you appoint anyone

Questions we’re asked in Navestock Common

Will our site in Navestock Common have to close for joint sealing?

In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.

Is hospital work, at somewhere like Suttons Manor Hospital, something you do?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How much does the work cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Do you work in Navestock Common?

Yes. Navestock Common falls within our area, and you can call 01277 525 020 or email drawings and photos to get started.

Are you fully insured?

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

What happens if it’s left?

Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly. Full removal and preparation is in every quote. Halls, stores and units around places like Navestock Common may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Pricing movement joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.

Different surfaces, different methods

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability.

Car park decks and ramps

Failed deck joints often show as leaks on the level below. The old seal comes out, the edges are prepared and the joint resealed, and we’ll tell you if any edges need repairing first.

Diagnose, treat, sign off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Jobs in and around smaller places like Navestock Common 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. We look at the joints, their width and how they’ve failed.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. We strip out the old seal and prepare the faces.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

  • Tell staff and tenants when we’ll be in
  • Clear stock, furniture or equipment away from the joints
  • Send asbestos survey details if the building is pre-2000

Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day. The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.

For an estate such as Suttons Manor Hospital, which lies north-west of Navestock Common, the joints in ramps, decks and long building elevations all need attention over time.
