Facade sealing in Hardley

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

What the job involves on each surface

Precast concrete panels

Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair.

Window and door perimeters

Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch as the frame moves.

Facade sealing in Hardley

Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. If you’re dealing with new sealant peeling off old mastic and failed sealant on precast panel joints, we can help. A specialist sealant contractor works differently from a general builder: in Hardley, that means joint design, primers and backing rod as standard.

Conversions of older rural buildings near smaller places such as Hardley 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.

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 spell out the cover before we begin.

New build and refits around Hardley

Hardley lies within about 2 miles of the sea. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Hardley 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.

For a contractor at a hotel such as Fountain Court Hotel, 1.1 miles north of Hardley, the mastic often has to be finished before a reopening date. Projects at colleges like Totton College Waterside Centre, 1.4 miles to the north-west of Hardley, tend to run to term dates, so the mastic is planned tightly. For contractors refurbishing units at places like Glenmore Business Park, less than half a mile north-west of Hardley, the mastic covers cladding panels, roller-door and window perimeters.

  • Providing access systems for the work

If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think before you book.

Hardley: questions and answers

Is Hardley too far out for you?

No. Places such as Hardley are covered as much as the big towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you cover business parks and estates near Hardley, such as Glenmore Business Park?

Yes, sites like Glenmore Business Park are within our area, along with the rest of Hardley. To start, just call the office on 01277 525 020 or email us with the unit, the joints involved and your access times.

How much does the work cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Can the building stay open while you work?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

Do you use silicone for external joints?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

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.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Why deal with it now?

Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice, saving a second set-up. Converted and older buildings near places like Hardley tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The price depends on the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.

Commercial clients in Hardley

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

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For work around Hardley, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Agree which areas must stay open
  • Tell staff and tenants when we’ll be in
