Facade sealing in Bix

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

Looking after the joints

Regular inspection catches problems early. Specifically:

  • Share access with other external trades
  • Keep the sealant details on the building file
  • Ask about asbestos in pre-2000 mastic
  • Avoid patch repairs on failed facade joints

Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

Facade sealing in Bix, done properly

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on commercial buildings in Bix. Where sealant is the specified fix, we also take on coping and flashing joints. If you’re dealing with old perimeter mastic that has dried out and previous reseals run over old sealant, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: in Bix, that means joint design, primers and backing rod as standard.

Sites around smaller places like Bix can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photos and the programme and we’ll quote to suit.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Common questions from Bix clients

Can you work to our programme on a site in or near Bix?

Yes, we work to the programme and the sequence the site sets. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Would you work within a site like Townlands Memorial Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Will you come and look before quoting?

It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs typically get a visit.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

What type of sealant goes on window perimeters?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Some joints call for hybrid, PU or polysulphide instead.

How much does the work cost?

There isn’t a price list, as every site differs. Send photographs or drawings and we will price it at a fixed figure.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather. If others near Bix 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. 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. The completed runs are checked with you, then the 12-month guarantee applies.

Getting the site ready

  • Flag any permit to work we will need
  • For older buildings, check the asbestos register before work
  • Point out parking and an unloading spot

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

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

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

Where we work in Bix

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

What happens if it’s left?

Topping up a failed joint typically 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. For buildings around smaller places like Bix, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Pricing facade joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

Why clients in Bix choose us

Work for main contractors and building owners

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Site staff or a sealant specialist?

Certain joints really need a specialist: for instance 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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Facades, frames and programmes in Bix

Bix is about 37 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. Bix is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.

Historic houses such as Greys Court, 1.3 miles to the south of Bix, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. New wings at hospitals like Townlands Memorial Hospital, 2.3 miles to the south-east of Bix, bring long runs of window and panel joints to seal.
