Facade sealing near Bidborough

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Bidborough need work, visits can be combined. You’ll have a fixed quote before work 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. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

What we need from you

  • Agree which areas must stay open
  • Let us know about inductions and permits
  • Send asbestos survey details if the building is pre-2000

Ask for a quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Advice

How we handle facade sealing in Bidborough

Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. Most enquiries involve new sealant peeling off old mastic and hard, chalky sealant that no longer flexes, on coping and flashing joints, perimeter joints where frames meet the structure and shopfront frames. Whether you call it commercial sealant work, mastic application or joint sealing, in Bidborough it comes down to the same thing: the right product in a properly prepared joint.

Construction in and around smaller places such as Bidborough is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Work we carry out in Kent comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or email us and we’ll arrange a return visit.

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

What we are called out for in Bidborough

Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained and rips when the facade moves.

These are often picked up first by site or facilities staff:

  • Sealant pulling away from frames or panels
  • Failed sealant on precast panel joints
  • Failed seals around shopfront and entrance frames
  • Staining on stone next to old sealant

University estates such as Canterbury Christ Church University - Salomons, 1.1 miles to the south of Bidborough, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

What to look for in a quote

  • What the guarantee covers, and for how long
  • Their public liability cover
  • How the joint faces will be prepared and primed
  • Their plan for phasing and protecting the area

How to choose a sealant contractor

New build and refits around Bidborough

Bidborough sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. Bidborough lies roughly 27 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.

New wings at hospitals like Tonbridge Cottage Hospital (to the north-east of Bidborough) bring long runs of window and panel joints to seal. Further education sites such as West Kent College (1.7 miles north-east of Bidborough) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Bidborough is about 3 miles north-west of Royal Tunbridge Wells, in Kent. Bidborough sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.

What happens if it’s left?

Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once. Around Bidborough, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

A quote for facade joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

Why appoint us

  • Workmanship guaranteed for 12 months
  • Constructionline member
  • Products installed to the manufacturer’s instructions
  • A fixed quote before work starts

Read what affects the cost or how we’re accredited.

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • Distance, for remote addresses
  • Phasing around occupants
  • Removal of failed or old sealant
  • The total length or number of joints

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Details that help us quote

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

  • Any specification or named product
  • Asbestos survey details if the building is older
  • The site address and postcode
  • A wide shot and a close-up of the area

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or email drawings and photos.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Water getting in through cracked render or porous masonry
  • Render or concrete edges that have broken away
  • Movement beyond what any sealant can handle

If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

Surfaces we seal

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

Questions we’re asked in Bidborough

Can you work at a site such as Speldhurst Business Park, by Bidborough?

Yes, sites like Speldhurst Business Park are within our area, along with the rest of Bidborough. To start, just call the office on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Can you take on a job at a hospital such as Tonbridge Cottage Hospital?

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

Is it okay to overlay old mastic?

No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.

Will you just go over the old sealant?

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

What do you charge?

Every job gets its own fixed quote. For yours, ring 01277 525 020 or send details through our quote form with a description of the work.

Do you take on multi-site work?

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

Do you replace failed glazing units?

No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters across the facade.
