Facade sealing across East Sheen

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Different surfaces, different methods

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod.

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first.

About our facade sealing in East Sheen

Facade sealants sit in the sun, rain and frost every day, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. The enquiries we see most involve water coming in around window frames and previous reseals run over old sealant, on shopfront frames, coping and flashing joints and stone and brick facade joints. Whoever orders the work in East Sheen, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

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

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Our process

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on 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 East Sheen can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Before we start on site

  • Share the asbestos register for older buildings
  • Have the specification and drawings to hand
  • Agree which areas must stay open

Owners, agents and contractors

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around East Sheen. One quote can cover more than one site, which keeps the paperwork simple.

Doing it in-house

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Questions about East Sheen

Does your area include sites such as Kew Retail Park, near East Sheen?

Yes, sites like Kew Retail Park are within our area, along with the rest of East Sheen. 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. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it

Do you guarantee your work?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Do we need an asbestos check before resealing?

For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder, so ask for it before we start. If asbestos is suspected, work stops until it is tested.

Do you replace failed glazing units?

No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters on commercial buildings.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

What type of sealant goes on window perimeters?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, as the specification or substrate requires.

Why it’s worth doing now in East Sheen

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, which is often the biggest saving. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Why appoint us

  • Failed material removed, not covered up
  • Fully insured
  • Colours chosen to suit frames, cladding or finishes where possible
  • Health and safety: CHAS accredited

Aftercare for building managers

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Note when each elevation was last resealed
  • Check the asbestos register before old mastic is disturbed
  • Clear debris that holds water against joints
  • Add perimeter sealant to planned maintenance checks

Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.

Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

Mastic packages on East Sheen sites

A 2-mile radius around East Sheen takes in plenty of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. As part of Greater London, East Sheen 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.

Projects at schools like Thomson House School work to term dates, so mastic is programmed tightly. Hotels like Kew Gardens Hotel (1.2 miles north-west of East Sheen) rarely close for long, so refurbishment mastic is phased floor by floor. On a healthcare site such as Barnes Hospital, 0.5 miles east of East Sheen, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

East Sheen is about 3 miles west of Fulham, in Greater London. If you are looking for facade sealing in East Sheen, we can help, as we do across Greater London. East Sheen is one of 764 places we cover in Greater London. London is covered too, some 8 miles away.
