About our expansion joint sealing in Foxholes

We’ve been sealing expansion and movement joints for over 20 years for contractors, facilities managers and owners. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. Most enquiries involve layers of sealant in a movement joint and torn sealant in brick or block movement joints, across car park decks and ramps, cladding panel joints and precast concrete panel joints. A specialist sealant contractor works differently from a general builder: in Foxholes, that means joint design, primers and backing rod as standard.

Work in a smaller place like Foxholes is usually one building at a time, so we gather photos and measurements first. That way the right materials come on the day and the job is done in one visit where possible.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Why act early in Foxholes

Resealing is usually the answer, not replacing the element. If the material either side is sound, a properly prepared reseal restores the joint. We’ll flag where edges need repair before sealing. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

  • Colour agreed before work starts

Signs you need expansion joint sealing in Foxholes

Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch and opens at the next temperature swing.

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

  • Torn sealant in brick or block movement joints
  • Sealant pulling off the joint face
  • Arrises breaking up along floor joints
  • Brittle, chalky sealant on external joints

Another example is Madford Retail Park, which lies west of Foxholes, where floors and yards would be done in stages around the occupiers.

Questions to ask before you book

  • Are they CHAS accredited or on Constructionline?
  • Their plan for phasing and protecting the area
  • The named product and why it was chosen
  • Who will actually carry out the work

Questions to ask before you appoint anyone

Different surfaces, different methods

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. A semi-rigid filler is common in trafficked industrial floors, with a flexible sealant where movement is larger.

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond.

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a job in Foxholes, the main thing is a clear picture of the work, so send photos of each area. You’ll then get a fixed price for the work.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Getting the site ready

  • Have the specification and drawings to hand
  • Share your working hours and any access restrictions
  • Warn occupants and staff about the work

Quoting for work in Foxholes

A fixed quote reflects the actual work. It takes account of:

  • The total length or number of joints
  • Site requirements such as inductions and permits
  • Travel to remote or island sites
  • How accessible the joints are

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Before you send an enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • Any dates the work must fit around
  • Anything awkward about access or site hours
  • Where the site is, with the postcode
  • What the building is and how it’s used

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, phone 01277 525 020 or email a schedule or drawings.

Where floor joints take the most wear near Foxholes

Foxholes sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint. Foxholes is about 20 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift.

Estates like Taylor Trading Estate, 0.7 miles to the north of Foxholes, combine warehouse slabs, yards and loading bays, all with joints under wheels. A healthcare site such as Hertford County Hospital, 1.5 miles to the west of Foxholes, depends on car parks, ramps and service yards whose joints take traffic all day.

Foxholes is about 1 mile east of Hertford, in Hertfordshire. Anywhere in SG13, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 371 places across Hertfordshire fall within our area, including Foxholes.

FAQs: Foxholes

Is hospital work, at somewhere like Hertford County 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.

Is Foxholes too small for you to travel to?

No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Do you reseal car park expansion joints?

Yes. These joints take wheels, salt and water, so product choice matters and broken edges are flagged before sealing.

Why has the sealant in our expansion joints split?

Most often the movement is too much for the product or the joint width. That’s why we check width, depth and movement class before quoting.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Do the joint edges need to be sound before sealing?

The edges have to be sound. Where they’ve broken up, we’ll tell you they need repairing first, so the new seal has something to grip.

Can you work to our specification?

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.
