Facade sealing for businesses in Bordon

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

Why act early in Bordon

Topping up a failed joint usually buys very little time. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Why us?

  • Commercial sealant work since 2005
  • Coloured sealants to suit the setting, where available
  • Colour options checked against the specified product
  • Constructionline member for supplier checks

Facade sealing for commercial buildings in Bordon

We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. If you are dealing with new sealant peeling off old mastic and staining on stone next to old sealant, we can help. A single leaking joint is often how a building in Bordon first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

On a small site around Bordon, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we’ll time the work so nothing waits on us.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What the job involves on each surface

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building.

Window and door perimeters

Aluminium, PVC-U and timber frames each have their own preparation needs. We clean and prime to the sealant maker’s guidance for each surface.

Questions we are asked in Bordon

Do you take on work at healthcare sites like Chase Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you cover business parks and estates near Bordon, such as Woolmer Trading Estate?

Yes. Estates, retail parks and business parks around Bordon, Woolmer Trading Estate among them, are all within reach. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Do you use silicone for external joints?

It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Will rain stop the work?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Cold, damp mornings can delay a start.

How do I request a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it.

Building and refurbishing in Bordon

Bordon is in the South East, one of the UK’s drier regions. 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. Bordon is about 43 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.

Projects at schools like Bordon Infant School work to term dates, so mastic is programmed tightly. Units on estates such as Woolmer Trading Estate, under half a mile south of Bordon, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Bordon is about 10 miles south-west of Aldershot, in Hampshire. Across the GU35 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 723 places across Hampshire fall within our area, including Bordon. Sites around Portsmouth have their own page, about 23 miles away.

Commercial sites across GU35 are covered for facade joints. Streets here include High Street, Station Road and Cobbett Square, and sites on any of them can send details for a fixed quote. You’ll find Bordon on or near the A325 and B3002. If your building is just outside Bordon, we cover Pinewood Village (1 mile north), Deadwater (1 mile east), Whitehill (1 mile south), Lindford (1 mile north-east) and Hollywater (1 mile south-east). A short drive away, we cover Basingstoke (15 miles north-west), Farnborough (13 miles north), Fleet (11 miles north), Aldershot (10 miles north-east), Alton (5 miles north-west) and Petersfield (8 miles south-west).

We work on buildings around Mill Chase Academy, among other places. The closest station to Bordon is Liphook station, roughly 4.1 miles south-east. Other landmarks nearby include The Romany Museum (3.6 miles west) and Chase Community Hospital (0.6 miles south). Not far away are Selborne Hill and Deadwater Valley.

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. If neighbouring businesses or buildings around Bordon need work too, visits can be combined. Tell us your site hours and we will plan around them.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Before we start on site

  • Let building users know which areas are affected
  • Share the asbestos register for older buildings
  • Share your working hours and any access restrictions

Related advice

Maintenance after handover

Regular inspection catches problems early. In particular:

  • Walk the elevations once or twice a year
  • Ask about asbestos in pre-2000 mastic
  • Clear debris that holds water against joints
  • Avoid patch repairs on failed facade joints

Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; record the locations.

Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones.

What sealant work can’t fix

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Damp caused by condensation inside the building
  • Joints too narrow for the movement they take, which need redesign
  • Damaged frames that need replacing

If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

Where we work in Bordon

  • Window and door perimeters

Signs you need facade sealing in Bordon

Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and movement soon pulls it away.

What tends to prompt an enquiry:

  • Unsightly perimeter sealant on a visible elevation
  • Damp patches beside frames after rain
  • Old perimeter mastic that has dried out
  • Facade joints cracked through the middle

Extensions at sites like Chase Hospital (to the south of Bordon) usually sit beside working departments, and the mastic follows strict access rules.
