Facade sealing in Horden

Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds, using sealants classified for facade or glazing use. If you have damp patches beside frames after rain and perimeter joints where frames meet the structure, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Horden tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like Horden, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Questions we’re asked in Horden

Is a hospital such as Benenden Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can the mastic package for our job in Horden follow the site programme?

Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you find out why a window is leaking?

Yes. Photos help, and you can give us a call on 01277 525 020 or send details through our quote form to arrange a visit. Many frame leaks are sealant failures, though not all, and we’ll be honest about which it is.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Facade sealing around Horden: what changes locally

At about 36 miles from central London, Horden is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand. Horden is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.

School extensions, at buildings such as Colliers Green Church of England Primary School, usually run to the summer holidays, mastic included. New wings at hospitals like Benenden Hospital, 5.9 miles to the south-east of Horden, bring long runs of window and panel joints to seal.

Horden is about 6 miles south-east of Paddock Wood, in Kent. We cover commercial sites throughout Horden, whether it’s a single job or part of a planned programme. We work across 931 places in Kent, from busy centres to rural villages. For work in that direction, see our Brighton page, about 35 miles away.

Business premises anywhere in TN17 and TN12 are within our area. If your site is on Hill Top and Husheath Hill or close by, send details and we will quote for facade joints. If your building is just outside Horden, we cover Colliers Green (1 mile south), Flishinghurst (2 miles south), Marden Thorn (2 miles north), Knox Bridge (2 miles east) and Cranbrook Common (3 miles east).

Maintenance after handover

Problems stay small when the joints are checked regularly. In particular:

  • Keep the sealant details on the building file
  • Don’t wait for a second leak before calling
  • Keep pressure washers away from fresh sealant
  • Clear debris that holds water against joints

Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal.

Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:

  • Arranging specialist high-level access, which is planned with the client
  • Work on the window or framing system itself
  • Damaged frames that need replacing

If you’re not sure, just call 01277 525 020 or email the details over and we will give you a straight answer before you book.

Surfaces we seal

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

What sets the cost

These are the things that shape the price:

  • Access and working height
  • Joint width, depth and condition
  • Phasing around occupants
  • Location, for remote and island sites

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you’re ready.

Sending details for a quote

The more we know, the firmer the quote. When you get in touch, include:

  • Specification clauses that apply
  • When you need the work done
  • What the building is and how it’s used
  • Rough lengths or quantities, or drawings if you have them

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

Our process

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. For a building around Horden, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  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.

Getting the site ready

  • Make sure the joints can be reached
  • Explain the parking and delivery arrangements
  • Confirm the product named in the specification

Quotes

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or send details through our quote form.

Related advice

Building owners, agents and FMs in Horden

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

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Horden can form part of a wider programme.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
