Facade sealing across The Mint

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

How the job changes by surface

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building.

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface, often a low-modulus silicone or hybrid.

Facade sealing in The Mint, done properly

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. Site teams most often ask us about sealant pulling away from frames or panels and patch repairs that keep failing, on coping and flashing joints, cladding panel joints and perimeter joints where frames meet the structure. Facilities teams, main contractors and managing agents in The Mint tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Sites around smaller places like The Mint can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photographs and the programme and we will quote to suit.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:

  • Movement beyond what any sealant can handle
  • Arranging specialist high-level access, which is planned with the client
  • Water getting in through cracked render or porous masonry

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Where we work in The Mint

Your questions answered

Does your area include sites such as Ham Barn Business Park, near The Mint?

Yes. We cover The Mint and the area around it, including industrial estates, business parks and retail parks such as Ham Barn Business Park. To start, just speak to us on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

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

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Do you run new sealant over the existing bead?

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

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Building and refurbishing in The Mint

The Mint 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. Central London is about 46 miles from The Mint. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

When units on a site such as Ham Barn Business Park, 1.2 miles north-west of The Mint, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Projects at schools like Liss Junior School work to term dates, so mastic is programmed tightly.

The Mint is about 4 miles north-east of Petersfield, in Hampshire. Across the GU33 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Across Hampshire, 723 places are covered, The Mint among them. Sites around Portsmouth have their own page, about 19 miles away.

We cover the GU33 postcode districts. Just outside The Mint, we also work in Liss Forest (1 mile north-west), Liss (1 mile south-west), Rake (1 mile south-east), West Liss (1 mile south-west) and Hill Brow (1 mile south). A short drive away, we cover Havant (14 miles south), Horndean (11 miles south-west), Aldershot (14 miles north), Alton (8 miles north-west), Waterlooville (13 miles south-west) and Petersfield (4 miles south-west).

Local landmarks in The Mint

Around The Mint, our work takes us to commercial buildings near The Temple Inn, among other places. The Mint’s nearest station is Liss station, about 0.8 miles south-west of the centre. Other landmarks nearby include Chase Community Hospital (3.9 miles north). For a walk, there’s Liss Riverside Railway Walk North and Wheatham Hill.

How a job runs

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Smaller jobs around The Mint can be grouped with others nearby, 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. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  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

  • Let us know about inductions and permits
  • Point out any areas we must not close
  • Arrange parking or a loading space

Do you need facade sealing in The Mint?

Overlaying old sealant is a common shortcut that fails quickly. Fresh silicone won’t stick to cured silicone.

It’s worth sending us details if you spot any of the following:

  • Damp patches beside frames after rain
  • Perimeter joints where frames meet the structure
  • Cladding panel joints that have opened up
  • Unsightly perimeter sealant on a visible elevation

New wings at hospitals like Chase Community Hospital, 3.9 miles north of The Mint, bring long runs of window and panel joints to seal.

Comparing quotes

  • Whether their applicators hold CSCS cards
  • Will RAMS and insurance details be available?
  • How long is the guarantee, and what does it include?
  • Will failed sealant be removed rather than covered?

How to choose a sealant contractor

Leave it or put it right?

Failed joints let in more than water: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. For buildings around smaller places like The Mint, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

What you get with us

  • Standard and matched colours in many product ranges
  • Over 20 years of commercial sealing
  • Failed material removed, not covered up
  • Clear, fixed quotes
