Facade sealing for Burnt Oak sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

What affects the price in Burnt Oak

Quotes vary with the job. Expect it to depend on:

  • Phasing around occupants
  • Induction, permit and paperwork requirements
  • Whether old sealant has to be cut out first
  • Specialist products, such as fire-rated or hygienic sealants

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Before you send an enquiry

A good diagnosis starts with the right details. Let us know:

  • Photos of the joints, close up and from further back
  • The asbestos register, for older buildings
  • When you need the work done
  • What the building is and how it’s used

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email a schedule or drawings.

Facade sealing in Burnt Oak, done properly

Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. We work on coping and flashing joints, shopfront frames and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are leaks at window and door perimeters and cold air coming in at window perimeters. Most enquiries from Burnt Oak start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Burnt Oak must meet its standards or pay the daily charge. Alongside that, sites normally need booked deliveries and a plan for where materials go.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Your questions answered

Can you take on a job at a hospital such as Edgware Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Will you plan work around the academic year at somewhere like Middlesex University?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.

What do you charge?

That depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

When something else is needed

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Joints too narrow for the movement they take, which need redesign
  • Damaged frames that need replacing
  • Specialist high-level access methods

If in doubt, give us a call on 01277 525 020 or email us and we will say what we think.

Surfaces we seal

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

Sites and facades in and around Burnt Oak

As part of Greater London, Burnt Oak is inside the ULEZ, which applies to every van on site. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. There are several hotels within about 2 miles of Burnt Oak. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.

When a college such as Stanmore College, 2.3 miles to the west of Burnt Oak, builds or refurbishes, the mastic package typically has to fit around students and staff. Work at a hotel such as The White Hart Hotel (to the west of Burnt Oak) tends to be programmed around bookings, mastic included. University estates such as Middlesex University, 1.2 miles to the south-east of Burnt Oak, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Burnt Oak is about 7 miles south-east of Watford, in Greater London. Commercial clients in Burnt Oak can call on us for facade joints. Across Greater London, 764 places are covered, Burnt Oak among them. Sites around London have their own page, about 10 miles away.

Surface by surface

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed.

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and we’ll mention any edges that need repair.

Why act early in Burnt Oak

Topping up a failed joint usually buys very little time. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Why us?

  • A Constructionline member, so easy to vet
  • 12 months’ guarantee on every job
  • Work to your specification and the manufacturer’s guidance
  • Colours confirmed for the specified product

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in 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. All of Greater London is in the ULEZ, and kerbside space in Burnt Oak can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  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. We hand over with our 12-month workmanship guarantee.

What we need from you

  • Have the specification and drawings to hand
  • Agree which areas must stay open
  • Arrange parking or a loading space

Advice

After the work

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Ask about asbestos in pre-2000 mastic
  • Share access with other external trades
  • Inspect facade joints on a regular cycle
  • Never let anyone seal over old sealant

Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal.

Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading inside the building.
