Common questions from South Woodford clients

Does a hotel in South Woodford need to shut while its sealant is renewed?

In most cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.

Will you take on work at estates like Woodford Trading Estate, close to South Woodford?

Yes. Estates, retail parks and business parks around South Woodford, Woodford Trading Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Can one contractor look after sealant on all our buildings?

Yes, within the areas we cover: South East England, Greater London and Scotland. One contact and one process for every building makes a portfolio easier to manage.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Can areas stay open during the work?

It’s normal for us to work in occupied buildings. We agree the order of areas, protect what’s nearby and close off only the section we are sealing.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Do you work in South Woodford?

Yes. We cover South Woodford, and you can ring 01277 525 020 or email a schedule or drawings to get started.

Commercial sealant contractors in South Woodford, done properly

We have applied sealant on commercial sites for over 20 years, and the documents buyers ask for are ready: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. If your site needs RAMS, an insurance certificate or CSCS details, say so and we’ll confirm with the quote. If you’re dealing with gaps behind commercial kitchen worktops and sinks and mouldy silicone around WCs, urinals and vanity tops, we can put it right, on kitchen worktops and splashbacks, movement joints in walls and floors and washrooms and tea points alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in South Woodford, preparation and product choice get the time they need.

Multi-site clients with buildings in and around South Woodford can put several sites on one programme, so standards and paperwork match across every site.

Buildings in a London area such as South Woodford rarely close for maintenance: occupied offices, ground-floor retail under residential floors and busy shared entrances. Work is split into zones agreed with the building or facilities manager, so the premises keep working around us.

What our 12-month guarantee covers is the way we did the job: 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.

Common problems we fix in South Woodford

If only one face has lost its grip, that’s an adhesion failure. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. It’s one of the commonest faults we find on earlier work.

Any of the following is a good reason to get the joints checked over:

  • Damp patches where an external joint has failed
  • External beads that have gone brittle and cracked
  • Earlier reseals applied straight onto the failed bead
  • Movement joints packed with grit and debris

Industrial estates such as Woodford Trading Estate (to the east of South Woodford) have offices, trade counters and welfare areas whose sealant ages like any other building’s.

Our contractor checklist

From enquiry to sign-off

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 each bead is tooled to a neat concave finish. All of Greater London is in the ULEZ, and kerbside space in South Woodford can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We start with the evidence: photos, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Confirm the product named in the specification
  • Let us know about inductions and permits

Advice

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Any access equipment needed
  • Specialist products, such as fire-rated or hygienic sealants
  • Removal of failed or old sealant
  • Working within restricted access windows

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

What to include in your enquiry

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

  • Access details, including height
  • The asbestos register, for older buildings
  • Photos of the joints, close up and from further back
  • What the building is and how it’s used

Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. If you have questions first, call 01277 525 020 or email us.

Owners, agents and contractors

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

Should maintenance staff do it?

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.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

After the work

A few simple habits keep the new joints working:

  • Check joints after other trades have worked nearby
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Act on the first lifting edges rather than waiting
  • Keep washroom and kitchen extraction working

In washrooms and kitchens, extraction makes a real difference to sealant life. Extraction that isn’t working keeps the joints wet, which is how mould gets back in. Your maintenance team can look at extract fans at the same time.

Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. At that point it’s a repair job rather than a reseal.

Frontages, fit-outs and joints in South Woodford

The area within 2 miles of South Woodford holds plenty of hotels. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter. Contractor rules in London buildings can be strict, with inductions, permits and timed loading all normal. We plan around them and agree phasing so tenants and customers aren’t disrupted.

For premises near Wood Street station, which lies west of South Woodford, footfall is part of the plan: work is phased so shops and offices keep trading. For a hotel such as The Woodford Hotel, which lies west of South Woodford, the colour of a joint at the bar or the bath matters to the look of the room.
