Sites and facades in and around Fullwell Cross

Fullwell Cross has a number of hotels close by, all within 2 miles. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Fullwell Cross. Delivery slots and scarce storage shape how and when the mastic goes in.

Units on estates such as Newbury Retail Park (to the south of Fullwell Cross) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. When a college such as New City College, 1.2 miles south of Fullwell Cross, builds or refurbishes, the mastic package typically has to fit around students and staff.

Fullwell Cross is about 2 miles east of Woodford, in Greater London. Businesses, contractors and managing agents in Fullwell Cross use us for work on facade joints, as part of our coverage of Greater London.

How we handle facade sealing in Fullwell Cross

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We plan for that and keep you updated. The enquiries we see most involve damp patches beside frames after rain and failed seals around shopfront and entrance frames, across stone and brick facade joints, shopfront frames and window and door perimeters. A specialist sealant contractor works differently from a general builder: in Fullwell Cross, that means joint design, primers and backing rod as standard.

Every London site, Fullwell Cross included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. 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: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How the job changes by surface

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one.

Our process

Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. In Fullwell Cross, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Before we start on site

  • Move anything stored against the joints
  • Send any specification or drawings in advance
  • Let us know about inductions and permits

Advice

What affects the price in Fullwell Cross

What shapes the price:

  • How accessible the joints are
  • Quantities, in metres or numbers
  • The size and state of each joint
  • The product specified

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.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • How the joints are reached, and at what height
  • The type of building and who uses it
  • Whether an asbestos survey exists
  • Where the site is, with the postcode

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

FAQs: Fullwell Cross

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

Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Is Newbury Retail Park, near Fullwell Cross, within your area?

Yes. We cover Fullwell Cross and the area around it, including industrial estates, business parks and retail parks such as Newbury Retail Park. A few photographs and the unit address let us price the work.

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.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Do you offer coloured sealant?

It depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Can you find out why a window is leaking?

Yes. Photos help, and you can ring 01277 525 020 or use the quote form to arrange a visit. Many frame leaks are sealant failures, though not all, and we will tell you which.

Are you CHAS accredited?

Yes. We’re CHAS accredited and a Constructionline member.

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. 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.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Owners, agents and contractors

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

When to call us in Fullwell Cross

Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.

Common reasons buildings call us in:

  • Water coming in around window frames
  • Draughts around frames and panels
  • Discoloured or dirty facade joints
  • Gaps between rainscreen or cladding panels

On a healthcare site such as King George Hospital, 1.6 miles south-east of Fullwell Cross, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
