Facade sealing in Connaught Village, done properly

Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. Site teams most often ask us about failed seals around shopfront and entrance frames and water coming in around window frames, on window and door perimeters, cladding panel joints and stone and brick facade joints. A specialist sealant contractor works differently from a general builder: on jobs in Connaught Village, preparation and product choice get the time they need.

Every London site, Connaught Village included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Alongside that, sites usually need booked deliveries and a plan for where materials go.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Your questions answered

Can you work at a site such as Brompton Cross District Shopping Centre., by Connaught Village?

Yes. Estates, retail parks and business parks around Connaught Village, Brompton Cross District Shopping Centre. Among them, are all within reach. A few photographs and the unit address let us price the work.

Do you work in London buildings with loading restrictions?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it

Do you have public liability insurance?

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

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

Do you provide access for facade work?

We agree access with the client at the start. Tell us about access: existing scaffold, what you are arranging and any site restrictions, and the quote will reflect it.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Common problems we fix in Connaught Village

Sometimes the substrate is the problem: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.

What tends to prompt an enquiry:

  • Previous reseals run over old sealant
  • Staining on stone next to old sealant
  • Perimeter sealant that has split or peeled away
  • Hard, chalky sealant that no longer flexes

For contractors at a college like London College of Fashion, which lies east of Connaught Village, perimeters and internal sealant are timed for the holidays.

What to look for in a quote

  • What site paperwork they can supply
  • Are they CHAS accredited or on Constructionline?
  • Is the sealant right for the movement and the substrate?
  • How the joint faces will be prepared and primed

How to choose a sealant contractor

What the job involves on each surface

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.

Window and door perimeters

Frames grow and shrink with temperature, and the perimeter joint has to follow. The rod limits depth, leaving the bead able to flex without tearing.

Our process

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Planning a London job such as one in Connaught Village starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and both faces cleaned back.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Before we start on site

  • Confirm the product named in the specification
  • Agree which areas must stay open
  • Let building users know which areas are affected

What sets the cost

Before we quote, we look at:

  • Working within restricted access windows
  • Quantities, in metres or numbers
  • Travel to remote or island sites
  • Any access equipment needed

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Asbestos survey details if the building is older
  • Anything awkward about access or site hours
  • Drawings or a marked-up plan, if available
  • The type of building and who uses it

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. If you have questions first, call the office on 01277 525 020 or email the details over.

Honest limits

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Water getting in through cracked render or porous masonry
  • Cracked or spalling substrates that need repair before sealing
  • Replacing glass or failed glazing units

If in doubt, phone 01277 525 020 or email us and we’ll say what we think.

Surfaces we seal

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

Work for main contractors and building owners

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Connaught Village can form part of a wider programme across Greater London.
