Facade sealing for Nash sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Facade sealing in Nash, done properly

Managing agents and owners in Nash ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. Site teams most often ask us about hard, chalky sealant that no longer flexes and perimeter sealant that has split or peeled away, across cladding panel joints, window and door perimeters and stone and brick facade joints. Facilities teams, main contractors and managing agents in Nash tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Sites around smaller places like Nash can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photos and the programme and we will quote to suit.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

  • Removal of failed or old sealant
  • Location, for remote and island sites
  • Any access equipment needed
  • Whether the work must be split into stages

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

What to include in your enquiry

There’s no need for a formal survey. These details are enough to start:

  • The postcode of the building
  • Rough lengths or quantities, or drawings if you have them
  • Any dates the work must fit around
  • Clear photos of the problem areas

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, ring 01277 525 020 or send details through our quote form.

Owners, agents and contractors

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Nash can sit alongside others in a wider programme.

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

From enquiry to sign-off

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. If others near Nash need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

What we need from you

  • Tell us what induction or permit system the site runs
  • Clear stock, furniture or equipment away from the joints
  • Let building users know which areas are affected

Building and refurbishing in Nash

The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team. Nash lies roughly 60 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.

Recladding or extending a unit at a site like Wingham Industrial Estate, 1.7 miles south-west of Nash, brings panel joints and frame perimeters into the programme. Hospital estates such as St Martins Hospital (6 miles west of Nash) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Nash is about 7 miles east of Canterbury, in Kent. Our applicators travel to Nash for work on facade joints. Nash is one of 931 places in Kent on our list. For work in that direction, see our London page, about 60 miles away.

Work on facade joints is covered throughout CT3. Close to Nash, our area also takes in Hoaden (1 mile north-east), Perry (1 mile west), Shatterling (1 mile south-west), Elmstone (1 mile north) and Durlock (1 mile south-east). Bigger towns within reach include Canterbury (7 miles west), Margate (9 miles north-east), Dover (10 miles south), Folkestone (14 miles south), Ramsgate (8 miles north-east) and Broadstairs (10 miles north-east).

When to call us in Nash

The wrong product causes its share of trouble: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Neutral-cure, facade-grade products are what most external joints need.

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

  • Leaks at window and door perimeters
  • Perimeter joints where frames meet the structure
  • Cold air coming in at window perimeters
  • Patch repairs that keep failing

Older buildings in the area around Nash, such as Goodnestone Park, 3 miles to the south of Nash, need care when sealed: the product has to suit soft or historic materials.

Before you book anyone

  • Their plan for phasing and protecting the area
  • How the joint faces will be prepared and primed
  • Are they CHAS accredited or on Constructionline?
  • Is the sealant right for the movement and the substrate?

Our contractor checklist

What happens if it’s left?

Failed joints let in more than water: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. Around Nash, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

What you get with us

  • CHAS accredited
  • Colour options checked against the specified product
  • Products installed to the manufacturer’s instructions
  • Coloured sealants to suit the setting, where available

Your questions answered

Is a smaller place like Nash outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Is Wingham Industrial Estate, near Nash, within your area?

Yes. We cover Nash and the area around it, including industrial estates, business parks and retail parks such as Wingham Industrial Estate. Photos and a short description are enough for a first look.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

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 handle several sites?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

Will you check whether the sealant is causing the leak?

Yes. We check the sealant joints and report what we find before quoting. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
