Facade sealing for businesses in Edmonton

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

From enquiry to sign-off

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. In Edmonton, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  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. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Point out any areas we must not close
  • Make sure the joints can be reached

Facade sealing for commercial buildings in Edmonton

Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. We work on cladding panel joints, stone and brick facade joints and window and door perimeters, and the failures we are asked to look at most are hard, chalky sealant that no longer flexes and water coming in around window frames. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Edmonton, preparation and product choice get the time they need.

The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Edmonton 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.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Surface by surface

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone.

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint rather than the system it surrounds.

Leave it or put it right?

Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

Why us?

  • Colours confirmed for the specified product

Building and refurbishing in Edmonton

Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Edmonton. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.

Recladding or extending a unit at a site like Edmonton Green Shopping Centre (less than half a mile north-east of Edmonton) brings panel joints and frame perimeters into the programme. Extensions at sites like North Middlesex University Hospital (to the south-west of Edmonton) usually sit beside working departments, and the mastic follows strict access rules. School extensions, at buildings such as Brettenham Primary School, typically run to the summer holidays, mastic included.

Edmonton is about 9 miles north-east of City of Westminster, in Greater London. Looking for facade sealing in Edmonton? We can help. We work across 764 places in Greater London. We also cover London, around 9 miles from Edmonton.

We cover the N9, N18, N13 and EN1 postcode districts for facade joints. We cover commercial and managed buildings on The Broadway, Plevna Road and Galahad Road. Edmonton sits on or close to the B137 and B154, which helps when planning parking and deliveries for the job. Just outside Edmonton, we also work in Upper Edmonton (1 mile south), Picketts Lock (1 mile east), Northumberland Park (1 mile south), Ponders End (1 mile north-east) and Bush Hill Park (1 mile north-west). Nearby towns on our patch include London (9 miles south), City of Westminster (9 miles south-west), Marylebone (8 miles south-west), Kensington (10 miles south-west), St Pancras (7 miles south) and Shoreditch (7 miles south).

Local landmarks in Edmonton

Around Edmonton, our work takes us to commercial buildings near NiW Furniture pub, The Latymer School and Starks Field School and the streets around them. There’s a railway station in Edmonton itself: Edmonton Green station. Nearby you’ll also find Edmonton Green Shopping Centre (less than half a mile north-east) and North Middlesex University Hospital (1 mile south-west). The countryside around Edmonton includes Highams Park Lake and Ainslie Wood.

When it isn’t the sealant

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Specialist high-level access methods
  • Movement beyond what any sealant can handle
  • Damp caused by condensation inside the building

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

Joints and surfaces we work on

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

Doing it in-house

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Commercial clients in Edmonton

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Your questions answered

Could you schedule work at a campus like University of Portsmouth Walthamstow Campus for the vacation?

Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Do you take on work at healthcare sites like North Middlesex University Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can you send site paperwork?

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

Is it okay to overlay old mastic?

No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.

Is colour matching possible?

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

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
