How we handle facade sealing in Puddle Dock

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: 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 coping and flashing joints, and the failures we are asked to look at most are facade joints cracked through the middle and old perimeter mastic that has dried out. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Puddle Dock, preparation and product choice get the time they need.

Every London site, Puddle Dock 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.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

On site: what to expect

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. All of Greater London is in the ULEZ, and kerbside space in Puddle Dock can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We look at the joints, the drawings and the access before pricing.
  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. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

What we need from you

  • Tell us what induction or permit system the site runs
  • Explain the parking and delivery arrangements
  • Send your site hours and access windows

Advice

New build and refits around Puddle Dock

The ULEZ covers the whole of Greater London, Puddle Dock included, so site vehicles need to meet its standards or pay the daily charge. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.

For contractors at a college like New City College, which lies west of Puddle Dock, perimeters and internal sealant are timed for the holidays. For a contractor working at a hospital such as Hartswood Hospital, which lies north of Puddle Dock, perimeter and facade sealing is planned around patients and deliveries.

Puddle Dock is about 3 miles north of South Ockendon, in Greater London. We cover commercial sites throughout Puddle Dock. Across Greater London, 764 places are covered, Puddle Dock among them. We also cover London, some 17 miles away.

Leave it or put it right?

Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. Failed sealant in a building in Puddle Dock can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

Why choose Mastic Doctor in Puddle Dock

  • Coloured sealants to suit the setting, where available
  • Fully insured
  • Clear, fixed quotes
  • RAL and finish matching where the product range allows

Read our cost guide or how we’re accredited.

What sets the cost

Before we quote, we look at:

  • Site requirements such as inductions and permits
  • Which sealant the job calls for
  • Location, for remote and island sites
  • Backing rod, priming and other preparation

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Sending details for a quote

However big the job, the same details help:

  • Access details, including height
  • Whether the building will be occupied during the work
  • Where the site is, with the postcode
  • Photos of the joints, close up and from further back

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Questions we are asked in Puddle Dock

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

Can you work around term dates at a campus such as New City College?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can staff carry on working while you are here?

In most cases, yes. We phase the work so most of the building stays in use.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, which many sites require.

What’s the quickest route to a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

What will the job cost?

Each job is quoted on its own details. For yours, ring 01277 525 020 or send details through our quote form.

Do you work in Puddle Dock?

Yes. Sites across Puddle Dock are covered, and the same phone number covers every area.

Doing it in-house

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

What the job involves on each surface

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported.

Window and door perimeters

Frame materials vary, and so does the preparation. We clean and prime to the sealant maker’s guidance for each surface.

Signs you need facade sealing in Puddle Dock

Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. When the joint edges need repair first, we say so.

What tends to prompt an enquiry:

  • Water coming in around window frames
  • Sealant pulling away from frames or panels
  • Failed seals around shopfront and entrance frames
  • Patch repairs that keep failing

When units on a site such as Childerditch Industrial Park, 1.8 miles north-east of Puddle Dock, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Questions to ask before you book

  • How the existing material will be dealt with
  • What the guarantee covers, and for how long
  • How the joint faces will be prepared and primed
  • How joint depth will be controlled
