Questions about Windmill Hill

Is Windmill Hill too far out for you?

Not at all. Windmill Hill is within our area. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Can you work to our programme on a site in or near Windmill Hill?

Yes. The mastic is planned around your key stages. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

How many days will you need on site?

It depends on the scope, but the work usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

What will the job cost?

Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or email us with a description of the work.

About our facade sealing in Windmill Hill

Facade sealants sit in the sun, rain and frost every day, and they wear out over time. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. The enquiries we see most involve perimeter joints where frames meet the structure and draughts around frames and panels, across shopfront frames, perimeter joints where frames meet the structure and stone and brick facade joints. Whoever orders the work in Windmill Hill, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

For a site near Windmill Hill, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photos and the programme and we will quote to suit.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

For managing agents and facilities managers

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

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

What we are called out for in Windmill Hill

Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, then it splits or peels.

Most enquiries start with one or more of the following:

  • Weathered joints at frame-to-structure perimeters
  • Cladding panel joints that have opened up
  • Air leaks through failed facade joints
  • Damp patches beside frames after rain

When units on a site such as Threshelfords Business Park, 1.8 miles north of Windmill Hill, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

What your quote should include

  • Whether their applicators hold CSCS cards
  • The terms of the workmanship guarantee
  • What level of public liability insurance do they hold?
  • How they’ll work around occupants

Choosing a commercial sealant contractor

Cost factors for facade joints

The price varies from site to site. Expect it to depend on:

  • Whether old sealant has to be cut out first
  • Whether the work must be split into stages
  • The product specified
  • Induction, permit and paperwork requirements

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

What to include in your enquiry

However big the job, the same details help:

  • How the joints are reached, and at what height
  • Where the site is, with the postcode
  • Whether the building will be occupied during the work
  • Drawings or a marked-up plan, if available

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, call the office on 01277 525 020 or email drawings and photos.

After the work

Keep the joints in good shape with a few simple steps:

  • Brief window cleaners about newly sealed joints
  • Record the product and colour used on each elevation
  • Combine resealing with other works that need access
  • Add perimeter sealant to planned maintenance checks

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards using a matching sealant.

Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a building around Windmill Hill, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

What we need from you

  • Let building users know which areas are affected
  • Let us know about inductions and permits
  • Agree which areas must stay open

Advice

What happens if it’s left?

Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once, saving a second set-up. For buildings around smaller places like Windmill Hill, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why clients in Windmill Hill choose us

  • Products installed to the manufacturer’s instructions

Building and refurbishing in Windmill Hill

Windmill Hill sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. Windmill Hill lies roughly 42 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.

When a school such as Baynards Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. With historic properties like Layer Marney Tower (to the east of Windmill Hill) in the area, refurbishment work often meets old masonry that needs compatible sealants.
