Facade sealing in Gravesend

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’re dealing with failed sealant on precast panel joints and failed seals around shopfront and entrance frames, we can help. Whoever orders the work in Gravesend, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Construction in a town such as Gravesend is often smaller schemes: a few new flats, a school extension, a refurbished unit. The perimeter and facade joints on a small scheme need the same sizing and preparation as on a big one.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Facades, frames and programmes in Gravesend

Gravesend is within about 2 miles of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so joint design, primers and product choice deserve extra care. Gravesend sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.

Further education sites such as North West Kent College (0.7 miles east of Gravesend) are extended and refurbished from time to time, with mastic often programmed into the summer break. For contractors on a campus like University of Greenwich, which lies west of Gravesend, facade and perimeter sealing has to fit around students and term dates. Units on estates such as Canal Industrial Park (to the north of Gravesend) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Gravesend is about 9 miles north-west of Gillingham, in Kent. We cover Gravesend, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Gravesend is one of 931 places in Kent on our list for facade joints. For work in that direction, see our London page (21 miles or so).

Commercial sites across DA12 and DA11 are covered. Among the streets we cover are Christ Church Road, Hillside Drive and Laurel Avenue, and sites on any of them can send details for a fixed quote. Access to Gravesend is via the A2 and A226 among other routes. Close to Gravesend, our area also takes in Windmill Hill (1 mile north-west), Milton-next-Gravesend (1 mile north-east), Denton (1 mile east), Singlewell or Ifield (1 mile south) and Northfleet (1 mile west). Further afield, our area takes in Maidstone (13 miles south-east), Dartford (7 miles west), Sevenoaks (13 miles south-west), Swanley (9 miles west), Kings Hill (11 miles south) and Foley Park (12 miles south-east).

On site: what to expect

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. Parking and loading for town-centre jobs in Gravesend are worth mentioning when you send details. Industrial and business units usually have yard or car park space.

  1. First we review photographs, 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. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Getting the site ready

Looking after the joints

After handover, a little attention goes a long way:

  • Record the product and colour used on each elevation
  • Avoid harsh cleaners on facade sealant
  • Check that rainwater leaves the facade the way it was designed to
  • Combine resealing with other works that need access

Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly.

Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading inside the building.

Why it’s worth doing now in Gravesend

Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. A failed joint is easier to put right before damp shows inside. Once water gets in, there’s drying out and making good as well.

The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Why appoint us

  • Old sealant cut out, never sealed over
  • Fully insured
  • Work carried out by CSCS-carded applicators
  • Products installed to the manufacturer’s instructions

What sealant work can’t fix

Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:

  • Installing or repairing glazing systems
  • Providing access systems for the work
  • Joints too narrow for the movement they take, which need redesign

If you are not sure, just ring 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

Surfaces we seal

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

Building owners, agents and FMs in Gravesend

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

What sets the cost

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

  • Travel to remote or island sites
  • Whether old sealant has to be cut out first
  • The product specified
  • The total length or number of joints

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Sending details for a quote

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • The site address and postcode
  • Photos of the joints, close up and from further back
  • The product your specification calls for
  • What the building is and how it’s used

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Gravesend: questions and answers

Our building in Gravesend is near the coast: does that change the 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 Canal Industrial Park, near Gravesend, within your area?

Yes, sites like Canal Industrial Park are within our area, along with the rest of Gravesend. To start, just phone 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Do you cover Gravesend?

Yes. We take on work across Gravesend, and the same phone number covers every area.

Do you guarantee your work?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.

When can you be on site?

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.
