Perry Green: questions and answers

Will you take on work at estates like Lanham Business Park, close to Perry Green?

Yes, sites like Lanham Business Park are within our area, along with the rest of Perry Green. Send details of the unit and the work through our quote form for a quick quote.

Is Perry Green off your patch?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

How long will the joint resealing take?

It usually takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. We confirm the timescale with the quote.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

How we handle expansion joint sealing in Perry Green

A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water; the joint jams, its edges take the load and the arrises spall. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on car park decks and ramps, podiums and floor movement joints and blockwork control joints, and what we are called in for most is arrises breaking up along floor joints and torn sealant in brick or block movement joints. Facilities teams, main contractors and managing agents in Perry Green tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

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

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Proprietary pre-formed expansion joint systems

Not sure which it is? You can ring 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Where we work in Perry Green

  • Brickwork movement joints
  • Cladding panel joints
  • Car park decks and ramps
  • Precast concrete panel joints
  • Podiums and floor movement joints
  • Blockwork control joints

For managing agents and facilities managers

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

How a job runs

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a building around Perry Green, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. We look at the joints, their width and how they’ve failed.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

  • Warn occupants and staff about the work
  • Move anything stored against the joints
  • Arrange parking or a loading space

When to call us in Perry Green

Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it, so we tell you if the edges need repairing first.

Clients usually get in touch after noticing one or more of the following:

  • Water dripping through deck or ramp joints
  • Sealant peeling off one face of the joint
  • Joints packed with grit and debris
  • Brittle, chalky sealant on external joints

Schools like Alec Hunter Academy often have long brick elevations with movement joints that age quietly.

What to look for in a quote

  • The terms of the workmanship guarantee
  • Their public liability cover
  • Their plan for phasing and protecting the area
  • Do they follow the manufacturer’s priming guidance?

Choosing a commercial sealant contractor

Why deal with it now?

Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly and soon lets go. Full removal and preparation is in every quote. Halls, stores and units around places like Perry Green may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Why clients in Perry Green choose us

  • A range of standard colours, depending on the product

  • Colours chosen to suit frames, cladding or finishes where possible

How the job changes by surface

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves.

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement.

Warehouse floors and decks around Perry Green

Perry Green is about 40 miles from central London. The roads out of London are lined with trade parks and distribution sheds. Perry Green is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.

A healthcare site such as William Julien Courtauld Hospital, 3.5 miles to the west of Perry Green, depends on car parks, ramps and service yards whose joints take traffic all day. On a site such as Lanham Business Park, 1 mile west of Perry Green, the movement joints are in car park slabs, paving and building elevations.

Perry Green is about 3 miles south-east of Braintree, in Essex. We cover commercial sites throughout Perry Green. We work across 644 places in Essex, from busy centres to rural villages. Our London page has more on work in that area, about 40 miles away.
