Expansion joint sealing across Blake End

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

What happens if it’s left?

Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed and we’ll tell you honestly. One visit to deal with every failing joint makes more sense than several trips to a place like Blake End, rather than one at a time. Photos of every joint help us quote for the whole job.

A quote for movement joints depends on quantities, condition and access. Ask us for a fixed quote.

Why clients in Blake End choose us

  • Colour agreed before work starts
  • Failed material removed, not covered up
  • A range of standard colours, depending on the product
  • CSCS-carded applicators

About our expansion joint sealing in Blake End

For movement joints in Blake End, photos and approximate lengths are the best start. We’ll come and look where photographs don’t show enough before issuing a fixed quote. To discuss the joints first, call 01277 525 020 or email us. We work on cladding panel joints, precast concrete panel joints and podiums and floor movement joints, and the failures we’re asked to look at most are sealant peeling off one face of the joint and damp inside where a wall movement joint has failed. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Blake End is the same: the right product in a properly prepared joint.

Jobs around smaller places like Blake End are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

Every job we finish is backed by a 12-month workmanship guarantee, in Blake End as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Include every elevation and deck joint in periodic inspections
  • Note which joints were done, when, and with what
  • Treat a small split as a warning, not a cosmetic issue
  • Leave barriers in place until fresh joint sealant has cured

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal.

External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint. Catching it early keeps the water outside.

Building owners, agents and FMs in Blake End

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

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.

When to call us in Blake End

Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears.

It’s worth sending us details if you spot any of the following:

  • Debris jammed in movement joints
  • Car park joints leaking onto vehicles below
  • New sealant over old, now failing
  • Sealant peeling off one face of the joint

Another example is Concord Farm Business Centre, 1.6 miles south-east of Blake End, where floors and yards would be done in stages around the occupiers.

Questions to ask before you appoint anyone

How a job runs

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before we move to the next. For work around Blake End, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Before we start on site

  • Arrange parking or a loading space
  • Have the specification and drawings to hand
  • Make sure the joints can be reached

Site staff or a sealant specialist?

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Your questions answered

Can you work at a site such as Goulds Farm Industrial Estate, by Blake End?

Yes, sites like Goulds Farm Industrial Estate are within our area, along with the rest of Blake End. To start, just ring 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Is a hospital such as Braintree Community Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

What’s the difference between an expansion joint and a movement joint?

They’re closely related. Both let materials grow and shrink with temperature, moisture and load, and the seal across it keeps water and debris out.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

What do you charge?

There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.

Can you seal car park deck joints?

Yes. Let us know the opening hours and which levels or bays have to stay available.

Are you fully insured?

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