How we handle facade sealing in Debden

Weather decides a lot in facade sealing. 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. If you have cold air coming in at window perimeters and perimeter joints where frames meet the structure, we can put it right, on perimeter joints where frames meet the structure, coping and flashing joints and cladding panel joints alike. A single leaking joint is often how a building in Debden first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In a smaller place such as Debden, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.

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.

For managing agents and facilities managers

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

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.

Why deal with it now?

Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. In a smaller place such as Debden, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why clients in Debden choose us

Common questions from Debden clients

Can work at a site such as New City College fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Do you cover business parks and estates near Debden, such as Epping Forest Shopping Park?

Yes. Our area takes in Debden and its surroundings, with estates and business parks such as Epping Forest Shopping Park included. To start, just ring 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

How do we ask for a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Do you need facade sealing in Debden?

Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, so the new bead peels away within a season or two.

Common reasons buildings call us in:

  • Weathered facade joints that have lost their grip
  • Staining on stone next to old sealant
  • Patch repairs that keep failing
  • Damp patches beside frames after rain

Hotel extensions and refits, at places such as The Kings Head Hotel, which lies south of Debden, normally run between busy periods, so the sealing is squeezed into short windows.

Questions to ask before you book

  • How they handle RAMS and site documents
  • The terms of the workmanship guarantee
  • Their plan for phasing and protecting the area
  • Will CSCS-carded applicators be on site?

Questions to ask before you appoint anyone

How a job runs

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, and the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Several jobs near Debden can be grouped on one trip. Mention the building’s opening times and we will work within them.

  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. The existing bead comes out in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Getting the site ready

  • Share the asbestos register for older buildings
  • Flag any permit to work we will need
  • Confirm the product named in the specification

What we can’t put right

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Water getting in through cracked render or porous masonry
  • Movement beyond what any sealant can handle
  • Damaged frames that need replacing

If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think before you book.

Surfaces we seal

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

Facade sealing in Debden: the local picture

Debden lies roughly 13 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand. Rainfall across the South East, Debden included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.

For a contractor working at a hospital such as The Holly Private Hospital, which lies south-west of Debden, perimeter and facade sealing is planned around patients and deliveries. Projects at colleges like New City College, under half a mile to the north-west of Debden, tend to run to term dates, so the mastic is planned tightly.

Site staff or a sealant specialist?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
