Bushey: questions and answers

Can you take on a job at a hospital such as Spire Bushey Hospital?

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 Colne Valley Retail Park, near Bushey, within your area?

Yes, sites like Colne Valley Retail Park are within our area, along with the rest of Bushey. Send details of the unit and the work through our quote form for a quick quote.

What about RAMS and site documents?

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.

Do you replace failed glazing units?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.

What will the job cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

How we handle facade sealing in Bushey

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, so frosty or damp mornings can hold work back. We build that into the programme and tell you if the forecast changes the plan. We work on stone and brick facade joints, window and door perimeters and cladding panel joints, and what we are called in for most is perimeter joints where frames meet the structure and discoloured or dirty facade joints. Whoever orders the work in Bushey, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Older town-centre buildings in places like Bushey are often converted to new uses or extended, which puts new frames and panels against old brick, stone or render. Getting the product and primer right for both faces is what keeps those joints sound.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Mastic packages on Bushey sites

Bushey sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. There are a number of hotels within about 2 miles of Bushey. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.

When a school such as Little Reddings Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Building work at universities like Westminster University (4.9 miles south of Bushey) is often timed for the summer, mastic included.

Bushey is about 2 miles south-east of Watford, in Hertfordshire. Businesses, contractors and managing agents in Bushey can call on us for facade joints. We work across 371 places in Hertfordshire, large and small. Our London page has more on work in that area (15 miles or so).

If you need facade sealing in WD23, WD25 and HA7, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. We cover commercial and managed buildings on High Street, London Road and Chiltern Close. Access to Bushey is via the A41 and A409, so getting applicators and materials to site is simple. We also cover Bushey Heath (1 mile south-east), Oxhey (1 mile west), Watford Heath (1 mile west), Patchetts Green (1 mile north) and Carpenders Park (2 miles south-west). Nearby towns on our patch include Hemel Hempstead (9 miles north-west), St Albans (7 miles north), Welwyn Garden City (13 miles north-east), Harpenden (12 miles north), Cheshunt (14 miles east) and Hatfield (10 miles north-east).

What sets the cost

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

  • Specialist products, such as fire-rated or hygienic sealants
  • The site’s rules and procedures
  • Travel to remote or island sites
  • Working within restricted access windows

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Sending details for a quote

Whether it’s one area or a whole building, the same details help:

  • Specification clauses that apply
  • Asbestos survey details if the building is older
  • The postcode of the building
  • The type of building and who uses it

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Surface by surface

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end with backing and a facade-grade sealant.

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:

  • Replacing glass or failed glazing units
  • Render or concrete edges that have broken away
  • Movement beyond what any sealant can handle

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we will tell you honestly.

Where we work in Bushey

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

Why it’s worth doing now in Bushey

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts. In a town such as Bushey, a lot of buildings are older and have been altered over time, so joints between old and new are often the first to go. Resealing them early protects the building behind.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Why clients in Bushey choose us

  • Failed material removed, not covered up
  • One phone line for London, the South East and Scotland
  • CHAS accredited
  • Over 20 years of commercial sealing

When to call us in Bushey

Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.

If one of these sounds familiar, it’s time for a closer look:

  • Facade joints cracked through the middle
  • Patch repairs that keep failing
  • Perimeter joints where frames meet the structure
  • Weathered facade joints that have lost their grip

Projects at colleges like Harrow Weald College, 2.3 miles south of Bushey, tend to run to term dates, so the mastic is planned tightly.

What your quote should include

  • Do they follow the manufacturer’s priming guidance?
  • Can the work be phased to keep areas open?
  • The terms of the workmanship guarantee
  • Will CSCS-carded applicators be on site?

How to choose a sealant contractor

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building. Most work in Bushey is one building at a time: a school, a unit, an office or a block. We start with your photos, drawings or a site visit, then send a fixed quote.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Tell us your opening times and when work is allowed
  • For older buildings, check the asbestos register before work
  • Arrange parking or a loading space

Quotes

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or email drawings and photos.
