Bishop's Stortford: questions and answers

Must our site in Bishop's Stortford stop work while the joints are done?

Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we will plan from there.

Can you take on a job at a hospital such as Herts And Essex Community Hospital?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

How do I request a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or email the details over. Include photos or drawings if you have them.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do the joint edges need to be sound before sealing?

Sealant needs sound faces to bond to, so broken or crumbling edges have to be repaired first. Where it’s visible beforehand, we will say so when we quote.

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

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Many people call it an expansion joint, and either way it needs a sound seal.

About our expansion joint sealing in Bishop's Stortford

We cover the full range of movement joints: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it and we name it in the quote. The enquiries we see most involve hardened, cracked sealant on exposed facades and rain penetration at brick or block movement joints, on precast concrete panel joints, brickwork movement joints and cladding panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Bishop's Stortford it comes down to the same thing: the right product in a properly prepared joint.

Car parks and yards in towns like Bishop's Stortford take tyre loads and, in winter, de-icing salt. Resealing before the edges break up is far less disruptive than repairing them later.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Should maintenance staff do it?

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

What affects the price in Bishop's Stortford

Each job is priced on its own details. The main factors are:

  • How accessible the joints are
  • How much there is to seal
  • Whether the work must be split into stages
  • The product specified

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Sending details for a quote

Good information means a firmer quote. When you get in touch, include:

  • Any dates the work must fit around
  • Rough lengths or quantities, or drawings if you have them
  • The site address and postcode
  • Whether the building will be occupied during the work

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

From enquiry to sign-off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. Town-centre premises in Bishop's Stortford may have limited parking, so tell us what’s nearby. Industrial and business units typically have yard or car park space.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Getting the site ready

  • For older buildings, check the asbestos register before work
  • Share your working hours and any access restrictions
  • Point out parking and an unloading spot

Leave it or put it right?

Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly, so it fails quickly. We cut out the old seal and prepare the faces every time. In a town like Bishop's Stortford, a split, stained or mouldy joint is often the first thing visitors notice. Fresh sealant makes a building look maintained.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

What you get with us

  • Matching to RAL references, product permitting
  • Workmanship guaranteed for 12 months
  • Sealing commercial buildings since 2005
  • Specification-led, product-correct work

Signs you need expansion joint sealing in Bishop's Stortford

On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant. A sealant that isn’t trafficable won’t last there.

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

  • Rain penetration at brick or block movement joints
  • Chipped joint edges on forklift routes
  • Hardened, cracked sealant on exposed facades
  • Layers of sealant in a movement joint

For a school such as St Michael's Church of England Primary School, playground and building joints can be done in the holidays.
