Facade sealing for businesses in Bunce Common

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Providing access systems for the work
  • Work on the window or framing system itself
  • Joints too narrow for the movement they take, which need redesign

Not sure which it is? You can ring 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Where we work in Bunce Common

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

About our facade sealing in Bunce Common

Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, but not always. If the evidence points away from the sealant, we say so before quoting. If you have perimeter joints where frames meet the structure and weathered facade joints that have lost their grip, we can put it right. Facilities teams, main contractors and managing agents in Bunce Common tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Sites around smaller places like Bunce Common can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Site staff or a sealant specialist?

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. That’s why many clients bring in a specialist from the beginning.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Keeping the joints sound

After handover, these steps help:

  • Brief window cleaners about newly sealed joints
  • Never let anyone seal over old sealant
  • Combine resealing with other works that need access
  • Check that rainwater leaves the facade the way it was designed to

Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant.

Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading.

Common questions from Bunce Common clients

Can you work on a hospital site such as Dorking Community Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Can you work at a site such as Chesterfield Business Park, by Bunce Common?

Yes. Estates, retail parks and business parks around Bunce Common, Chesterfield Business Park among them, are all within reach. To start, just give us a call on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Do you provide access for facade work?

That varies with the building and the access on offer. Share what access exists or is planned when you send details.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Quoting for work in Bunce Common

Quotes vary with the job. Expect it to depend on:

  • Working within restricted access windows
  • Which sealant the job calls for
  • Site requirements such as inductions and permits
  • Joint width, depth and condition

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Sending details for a quote

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Access details, including height
  • Your programme or deadline
  • Whether an asbestos survey exists
  • Approximate linear metres or a joint schedule

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or send details through our quote form.

How the job changes by surface

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and we’ll mention any edges that need repair.

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end.

Facade sealing around Bunce Common: what changes locally

Bunce Common 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. At about 22 miles from central London, Bunce Common is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.

On a healthcare site such as Dorking Community Hospital (2.7 miles north-west of Bunce Common), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Units on estates such as Chesterfield Business Park (2.9 miles north-east of Bunce Common) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Bunce Common is about 3 miles south-east of Dorking, in Surrey. We send applicators to Bunce Common for facade joints. We work across 379 places in Surrey. There’s a separate page for London, about 22 miles away.

Diagnose, treat, sign off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. If others near Bunce Common 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. 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. 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

  • Clear stock, furniture or equipment away from the joints
  • Point out parking and an unloading spot
  • Tell us which areas need to stay in use
