About our facade sealing in Berry's Green

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range. We plan for that and keep you updated. Site teams most often ask us about weathered joints at frame-to-structure perimeters and failed sealant on precast panel joints, across coping and flashing joints, window and door perimeters and cladding panel joints. For commercial sealant work in Berry's Green, you deal with one contact from quote to sign-off, whether it’s one building or several.

The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Berry's Green must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

How a job runs

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Getting the site ready

  • Move anything stored against the joints
  • Arrange parking or a loading space
  • Send asbestos survey details if the building is pre-2000

FAQs: Berry's Green

Can you take on a job at a hospital such as Princess Royal University Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Can you cope with the access rules in a London building?

Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we will work to them.

Can you send site paperwork?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

Does the weather affect the work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Are you insured?

Yes. We’re fully insured, including public liability cover.

Can you look at water coming in around a frame?

Yes. Photos help, and you can ring 01277 525 020 or email the details over to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we’ll tell you which.

Do you offer coloured sealant?

That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

When it isn’t the sealant

Some faults sit outside our scope, and we say so rather than covering them up:

  • Joints whose design needs changing by the specifier
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Work on the window or framing system itself

If in doubt, give us a call on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

What we seal

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

For managing agents and facilities managers

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Site staff or a sealant specialist?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What sets the cost

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

  • Quantities, in metres or numbers
  • The product specified
  • Backing rod, priming and other preparation
  • Travel to remote or island sites

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Details that help us quote

We can often quote from photographs and a few details. Please tell us:

  • The type of building and who uses it
  • When you need the work done
  • Access details, including height
  • Rough lengths or quantities, or drawings if you have them

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Why it’s worth doing now in Berry's Green

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Getting scaffold, permits or access booked in Berry's Green takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
