About our facade sealing in Cooling Street

Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around. If you have patch repairs that keep failing and perimeter sealant that has split or peeled away, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in Cooling Street, that means joint design, primers and backing rod as standard.

Conversions of older rural buildings near smaller places such as Cooling Street bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.

We stand by our work with a 12-month guarantee. That covers our preparation and application.

Site staff or a sealant specialist?

Certain joints really need a specialist: for example 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.

General builders and handymen seal joints, but it isn’t their main trade. 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.

Why deal with it now?

Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. One visit to deal with every failing joint makes more sense than several trips to a place like Cooling Street, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

What you get with us

  • Specification-led, product-correct work
  • Standard and matched colours in many product ranges
  • Constructionline member for supplier checks
  • Fully insured, including public liability cover

Facades, frames and programmes in Cooling Street

With the shore within about 3 miles, Cooling Street counts as a coastal location. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Cooling Street is about 26 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

Hospital estates such as French Hospital, 3.8 miles south of Cooling Street, 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. Building work at universities like University of Greenwich - Medway, 3.3 miles to the south of Cooling Street, is often timed for the summer, mastic included.

Cooling Street is about 4 miles north of Rochester, in Medway. We cover Cooling Street, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 54 places in Medway, from busy centres to rural villages. There’s a separate page for London, about 26 miles away.

What sealant work can’t fix

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Cracked or spalling substrates that need repair before sealing
  • Work on the window or framing system itself
  • Arranging specialist high-level access, which is planned with the client

Not sure which it is? You can give us a call on 01277 525 020 or email us and we will tell you honestly before you book.

What we seal

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

What sets the cost

The price varies from site to site. Expect it to depend on:

  • Any access equipment needed
  • Whether old sealant has to be cut out first
  • Which sealant the job calls for
  • The site’s rules and procedures

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Sending details for a quote

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

  • Approximate linear metres or a joint schedule
  • Whether an asbestos survey exists
  • What the building is and how it’s used
  • The postcode of the building

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or email drawings and photos.

What we are called out for in Cooling Street

New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.

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

  • Old perimeter mastic that has dried out
  • Failed sealant on precast panel joints
  • Previous reseals run over old sealant
  • Water coming in around window frames

When units on a site such as Nuralite Industrial Estate (to the west of Cooling Street) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Comparing quotes

  • Are they CHAS accredited or on Constructionline?
  • Do they follow the manufacturer’s priming guidance?
  • How joint depth will be controlled
  • How long is the guarantee, and what does it include?

How to choose a sealant contractor

Your questions answered

Does the sea air around Cooling Street change the choice of sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Is Nuralite Industrial Estate, near Cooling Street, within your area?

Yes. Our area takes in Cooling Street and its surroundings, with estates and business parks such as Nuralite Industrial Estate included. To start, just speak to us on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

What do you charge?

It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Does weather matter for sealant work?

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

Is the work guaranteed?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Do you cover Cooling Street?

Yes. We cover Cooling Street, and the simplest way to start is to speak to us on 01277 525 020 or email us.

From enquiry to sign-off

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If others near Cooling Street need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  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. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Explain the parking and delivery arrangements
  • Warn occupants and staff about the work
  • Send any specification or drawings in advance
