Facade sealing in Newingreen, done properly

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range. We plan for that and keep you updated. The enquiries we see most involve air leaks through failed facade joints and patch repairs that keep failing, on cladding panel joints, coping and flashing joints and window and door perimeters. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Newingreen, that means joint design, primers and backing rod as standard.

Conversions of older rural buildings near smaller places such as Newingreen bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or email us and we will arrange a return visit.

Building and refurbishing in Newingreen

Newingreen lies within about 3 miles of the sea. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so we check the specified product suits the exposure before the first bead. Central London is about 57 miles from Newingreen. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.

Older buildings in the area around Newingreen, such as Westenhanger Castle, 0.5 miles to the north of Newingreen, need care when sealed: the product has to suit soft or historic materials. For a contractor working at a hospital such as Royal Victoria Hospital (5.9 miles east of Newingreen), perimeter and facade sealing is planned around patients and deliveries.

Newingreen is about 2 miles north-west of Hythe, in Kent. Looking for facade sealing in Newingreen? We can help, as we do across Kent. We work across 931 places in Kent. Our Brighton page has more on work in that area (54 miles or so).

Signs you need facade sealing in Newingreen

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.

It’s worth sending us details if you spot any of the following:

  • Patch repairs that keep failing
  • Failed seals around shopfront and entrance frames
  • Damp patches beside frames after rain
  • Hard, chalky sealant that no longer flexes

When a school such as Lympne Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Before you book anyone

  • Is the sealant right for the movement and the substrate?
  • Who will actually carry out the work
  • Proof of insurance

How to choose a sealant contractor

Looking after the joints

Problems stay small when the joints are checked regularly. Specifically:

  • Keep pressure washers away from fresh sealant
  • Note when each elevation was last resealed
  • Share access with other external trades
  • Keep sills, gutters and drainage paths clear

Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed rather than sitting against the joints.

Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and work stops until it’s tested if it’s suspected.

General trades versus a 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.

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.

Why deal with it now?

The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. Around Newingreen, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

From enquiry to sign-off

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Rural sites near Newingreen may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  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. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  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. We walk the finished joints with you before handing over.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Tell staff and tenants when we will be in
  • Send any specification or drawings in advance

Advice

Your questions answered

Does the sea air around Newingreen change the choice of sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Is Newingreen off your patch?

Not at all. Newingreen is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Do you seal facades in winter?

Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things throughout the job.

Can staff carry on working while you’re here?

Typically, yes. We phase the work so most of the building stays in use, with each area protected and signed.

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Can you quote from photos?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

What sets the cost

Before we quote, we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • Backing rod, priming and other preparation
  • The total length or number of joints
  • Site requirements such as inductions and permits

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What we need to price the job

Good information means a firmer quote. When you get in touch, include:

  • Photos of the joints, close up and from further back
  • The product your specification calls for
  • Access details, including height
  • The postcode of the building

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or email the details over.
