Need facade sealing in Jockey End?

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

From enquiry to sign-off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Jockey End are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Getting the site ready

  • Let us know about inductions and permits
  • Make sure the joints can be reached
  • Send asbestos survey details if the building is pre-2000

Facade sealing in Jockey End

Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around, and we will fit the work around it. Most enquiries involve air leaks through failed facade joints and staining on stone next to old sealant, on shopfront frames, cladding panel joints and coping and flashing joints. A specialist sealant contractor works differently from a general builder: in Jockey End, that means joint design, primers and backing rod as standard.

Sites around smaller places like Jockey End can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photographs and the programme and we’ll quote to suit.

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.

Maintenance after handover

Problems stay small when the joints are checked regularly. Specifically:

  • Investigate damp beside windows promptly
  • Keep pressure washers away from fresh sealant
  • Inspect facade joints on a regular cycle
  • Share access with other external trades

Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards using a matching sealant.

Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading behind the facade.

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Facade sealing in Jockey End: the local picture

At about 28 miles from central London, Jockey End is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. Jockey End is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack.

For contractors at a school such as Gaddesden Row JMI School, sealing has to be finished before term starts. Hospital estates such as Hemel Hempstead Hospital, 4.4 miles to the south of Jockey End, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Jockey End is about 4 miles north of Hemel Hempstead, in Hertfordshire. Commercial clients in Jockey End use us for work on facade joints, as part of our coverage of Hertfordshire. Our Hertfordshire coverage takes in 371 places. We also cover London, some 28 miles away.

Jockey End: questions and answers

Is Jockey End too far out for you?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Can the mastic package for our job in Jockey End follow the site programme?

Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can you work on upper floors?

That comes down to the access arranged for the job. When you call the office on 01277 525 020 or email us, describe the access, and we’ll plan the work with you.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Do you offer coloured sealant?

That depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Work on the window or framing system itself
  • Cracked or spalling substrates that need repair before sealing

Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

What we seal

  • Stone and brick facade joints
  • Shopfront frames
  • Coping and flashing joints
  • Cladding panel joints
  • Perimeter joints where frames meet the structure
  • Window and door perimeters

Why it’s worth doing now in Jockey End

Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. Converted and older buildings near places like Jockey End tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Why appoint us

  • Fully insured, including public liability cover
  • Coloured sealants to suit the setting, where available
  • Colours confirmed for the specified product
  • RAL and finish matching where the product range allows
