About our facade sealing in Wesley 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. We work on shopfront frames, perimeter joints where frames meet the structure and coping and flashing joints, and the usual reasons a site gets in touch are old perimeter mastic that has dried out and unsightly perimeter sealant on a visible elevation. A single leaking joint is often how a building in Wesley End first comes to us: we look at the rest while we’re there and tell you what we find.

Sites around smaller places like Wesley End can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What sets the cost

We price every job individually. The main factors are:

  • Quantities, in metres or numbers
  • Whether old sealant has to be cut out first
  • Joint width, depth and condition
  • How accessible the joints are

The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Details that help us quote

A good diagnosis starts with the right details. Tell us:

  • Whether an asbestos survey exists
  • Anything awkward about access or site hours
  • Rough lengths or quantities, or drawings if you have them
  • Specification clauses that apply

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

New build and refits around Wesley End

At about 45 miles from central London, Wesley End is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. Wesley End sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.

Units on estates such as Blois Meadow Business Centre, 2.6 miles north-west of Wesley End, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Historic houses such as Hedingham Castle (4.8 miles south-east of Wesley End) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Wesley End is in Essex. We cover commercial sites throughout Wesley End, whether it’s a single job or part of a planned programme. Wesley End is one of 644 places we cover in Essex for facade joints. Sites around London have their own page, roughly 45 miles from Wesley End.

What happens if it’s left?

If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once, saving a second set-up. One visit to deal with every failing joint makes more sense than several trips to a place like Wesley End, rather than one at a time. Photos of every joint help us quote for the whole job.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why us?

  • 12 months’ guarantee on every job
  • Failed material removed, not covered up
  • Colour agreed before work starts
  • Products installed to the manufacturer’s instructions

How a job runs

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Wesley End need work, visits can be combined. A fixed quote is given before anything starts.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • Point out parking and an unloading spot
  • Share the asbestos register for older buildings
  • Tell us which areas need to stay in use

Questions we’re asked in Wesley End

Is Wesley End too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Will you take on work at estates like Blois Meadow Business Centre, close to Wesley End?

Yes, sites like Blois Meadow Business Centre are within our area, along with the rest of Wesley End. A few photographs and the unit address let us price the work.

Can you look at water coming in around a frame?

Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one, and we’ll tell you which.

How much does the work cost?

There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed 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 it all comes out first.

How is access to upper-level joints handled?

We agree access with the client at the start. Let us know what access is in place or planned, and the quote will reflect it.

What site paperwork can you supply?

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.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Cracked or spalling substrates that need repair before sealing
  • Specialist high-level access methods
  • Movement beyond what any sealant can handle

Not sure which it is? You can give us a call on 01277 525 020 or email us and we will tell you honestly.

Where we work in Wesley End

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

How the job changes by surface

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.

Window and door perimeters

Window and door perimeters make up most facade sealing work. A low-modulus neutral-cure product, chosen for the frame and wall, goes in finished to throw water off the joint.
