When something else is needed

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Concrete or masonry repairs along the arrises
  • Leaks coming from the membrane rather than the joint seal
  • A joint that has to be widened or re-detailed before it can work

If in doubt, give us a call on 01277 525 020 or send details through our quote form and we will say what we think before you book.

  • Cladding panel joints

About our expansion joint sealing in Hatfield Broad Oak

Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic. If you have arrises breaking up along floor joints and joints where the bead has lost adhesion, we can put it right. One point of contact handles commercial sealant work in Hatfield Broad Oak from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Around smaller places such as Hatfield Broad Oak, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Expansion joint sealing in Hatfield Broad Oak: the local picture

Rainfall across the South East, Hatfield Broad Oak included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints. Hatfield Broad Oak is about 27 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day.

In and around Hatfield Broad Oak, the right filler or sealant for each joint depends on the traffic and the movement it takes.

Commercial clients in Hatfield Broad Oak

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

How the job changes by surface

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in, phased so parts of the car park stay open.

Brickwork and blockwork joints

Vertical movement joints in brick and block walls let the masonry grow and shrink. We use a sealant rated for the movement, normally low-modulus laid over backing rod at the correct depth.

When to call us in Hatfield Broad Oak

When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons, and it’s common on joints sealed in a hurry.

Any of the following is a good reason to get the joints checked over:

  • Car park joints leaking onto vehicles below
  • Debris jammed in movement joints
  • Sealant pulling off the joint face
  • Hardened, cracked sealant on exposed facades

A healthcare site such as Herts and Essex Hospital (4.1 miles north-west of Hatfield Broad Oak) depends on car parks, ramps and service yards whose joints take traffic all day.

Questions to ask before you book

  • Proof of insurance
  • Will CSCS-carded applicators be on site?
  • Whether primer will be used where the manufacturer specifies it
  • How the existing material will be dealt with

Questions to ask before you appoint anyone

Our process

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Rural sites near Hatfield Broad Oak may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  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. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Preparing the site

  • Let building users know which areas are affected
  • Tell us your opening times and when work is allowed
  • Tell us what induction or permit system the site runs

Ask for a quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Why deal with it now?

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. Converted and older buildings near places like Hatfield Broad Oak tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Why appoint us

  • Fully insured
  • Matching to RAL references, product permitting
  • Work to your specification and the manufacturer’s guidance
  • Old sealant cut out, never sealed over

FAQs: Hatfield Broad Oak

Does a site in Hatfield Broad Oak have to shut while its joints are sealed?

In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we’ll plan from there.

Is a hospital such as Herts and Essex Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

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. Removing asbestos is a job for asbestos specialists, not us.

Do you reseal car park expansion joints?

Yes. Let us know the opening hours and which levels or bays have to stay available and we will plan around them.

What timescale should we allow for resealing expansion joints?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. Typically it takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
