Commercial sealant contractors in Jockey End

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. Before anything is cut out, we ask for the asbestos register or survey, since managing asbestos is the dutyholder’s responsibility. Anything suspect is left alone until it has been tested. If you’re dealing with a top-up bead over failed sealant, now lifting and window and door perimeter joints that have cracked open, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Jockey End from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Occupied buildings in Jockey End need the work phased: washrooms in turn, floors in sections and entrances kept open.

Rural business units near smaller places such as Jockey End are frequently converted agricultural buildings. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What we are called out for in Jockey End

Every sealant joint is a maintenance item. Its life comes down to movement, UV and weather, how it’s cleaned, how much traffic passes it and what was used in the first place. On a busy commercial site several of those pile up at once, so periodic inspection matters more than any date on a schedule.

Most enquiries start with something like this:

  • External beads that have gone brittle and cracked
  • Sanitary sealant that has gone black and patchy
  • Greasy, split joints in a kitchen or tea point
  • Messy, uneven beads from earlier work that let the building down

A lasting commercial joint around Jockey End begins with the old bead fully out and the faces clean and dry.

Choosing a commercial sealant contractor

Diagnose, treat, sign off

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Smaller jobs around Jockey End can be grouped with others nearby. A fixed quote is given before anything starts.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. A fixed quote follows, with removal and preparation included.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

Preparing the site

  • Move anything stored against the joints
  • Send your site hours and access windows
  • Point out parking and an unloading spot

Advice

Sealant on show in Jockey End’s commercial buildings

Jockey End sits in one of the drier corners of the country, the South East. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings. Jockey End is about 28 miles from central London. This part of the South East is dense with business parks and out-of-town offices. If you have premises across the region, one contractor can cover them all.

Offices and shops close to stations such as Berkhamsted station (4.6 miles south-west of Jockey End) tend to be busy all day, so sealant work is planned around opening hours.

Jockey End is about 4 miles north of Hemel Hempstead, in Hertfordshire. Our applicators travel to Jockey End for work on sealant joints, handled exactly as we handle every other area. Across Hertfordshire, 371 places are covered, Jockey End among them. Our London page has more on work in that area.

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

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.

Honest limits

Honesty saves time and money. New sealant won’t cure:

  • Misted, cracked or failed glazing units (a glazier’s job)
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • A dripping trap, valve or pipe behind a fitting

If in doubt, call 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Surfaces we seal

  • External facade joints
  • Kitchen worktops and splashbacks
  • Movement joints in walls and floors
  • Floor and threshold joints
  • Window and door perimeters
  • Washrooms and tea points

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • Travel to remote or island sites
  • How much there is to seal
  • Site requirements such as inductions and permits
  • Which sealant the job calls for

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote when you’re ready.

Before you send an enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Anything awkward about access or site hours
  • The product your specification calls for
  • Where the site is, with the postcode
  • Any dates the work must fit around

Your questions answered

What documents will you need to give us for a job in Jockey End?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Can you supply sealant in our brand colour for a site in Jockey End?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Available colours for the product are confirmed with the quote.

Do you check for asbestos before removing sealant?

Some older mastics did contain asbestos. So we check the register first and stop work on anything suspect until it’s tested. HSE guidance on asbestos is a useful reference.

Is the old sealant taken out first?

Every scrap of failed sealant is removed before the new bead goes on. Sealing over traps water and lifts once the joint moves.

Can you take on work for an FM or managing agent?

Yes, and through main contractors too. We quote, schedule and report back in the way that suits your process.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

How do we get a quote?

Start with whatever information is to hand. We follow up with questions or a visit where needed, then a fixed quote.

How the job changes by surface

Fire-rated seals where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. The design and sign-off of fire stopping belong to the designer and building control, and we install to the specification.

Movement joints in walls and floors

Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. Failed seals let grit and water in, and the edges start to suffer. The new sealant is chosen for the movement and, on floors, the traffic.
