Facade sealing for businesses in Stratford

Facade sealing in Stratford, done properly

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits. We build that into the programme and tell you if the forecast changes the plan. We work on perimeter joints where frames meet the structure, shopfront frames and window and door perimeters, and the usual reasons a site gets in touch are water coming in around window frames and perimeter joints where frames meet the structure. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Stratford, preparation and product choice get the time they need.

Construction in a London area such as Stratford means working on constrained sites: limited storage, booked deliveries and access shared with other trades. Mastic is typically one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.

Our workmanship is guaranteed for 12 months, in Stratford as everywhere else we work. If our installation lets you down in that time, we return and fix it.

What sealant work can’t fix

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

  • Damp caused by condensation inside the building
  • Damaged frames that need replacing
  • Replacing glass or failed glazing units

Not sure which it is? You can call 01277 525 020 or email the details over and we will tell you honestly before you book.

Where we work in Stratford

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

Surface by surface

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface, as the specification sets out.

Brick and stone facades

Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one, with masked edges for a clean line.

Your questions answered

Will you take on work at estates like Maryland Industrial Estate, close to Stratford?

Yes. We cover Stratford and the area around it, including industrial estates, business parks and retail parks such as Maryland Industrial Estate. A few photographs and the unit address let us price the work.

Do you work in London buildings with loading restrictions?

Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for

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.

Will rain stop the work?

Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start.

Can the sealant be colour-matched?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Do you take on multi-site work?

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

Do you use silicone for external joints?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them, and we work to what is specified.

Our process

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  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

  • Send asbestos survey details if the building is pre-2000
  • Let building users know which areas are affected
  • Confirm the product named in the specification

Advice

After the work

Problems stay small when the joints are checked regularly. Specifically:

  • Insist on a full cut-out when joints are renewed
  • Report water ingress at frames as soon as it shows
  • Plan facade sealing alongside redecoration
  • Note when each elevation was last resealed

After heavy weather, check vulnerable elevations for signs of water inside. An early report normally means a small reseal rather than a bigger repair.

Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail.

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.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Facade sealing in Stratford: the local picture

There are a good number of hotels within about 2 miles of Stratford. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Site traffic in Stratford falls within London’s ULEZ, like everywhere else in Greater London. Deliveries are booked and storage is tight, so mastic materials come in as needed.

For contractors at a college like Ebrahim College (under half a mile south-east of Stratford), perimeters and internal sealant are timed for the holidays. For contractors refurbishing units at places like Maryland Industrial Estate (0.5 miles north-east of Stratford), the mastic covers cladding panels, roller-door and window perimeters. Hospital estates such as Homerton University Hospital (1.9 miles west of Stratford) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Stratford is about 5 miles north-east of London, in Greater London. If you are looking for facade sealing in Stratford, we can help. We work across 764 places in Greater London.

Why it’s worth doing now in Stratford

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. Getting scaffold, permits or access booked in Stratford takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.

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

Why appoint us

  • A fixed quote before work starts
  • Colour options checked against the specified product
  • CSCS-carded applicators
  • Public liability insurance in place
