Facade sealing for commercial buildings in Midhurst

External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. Most enquiries involve perimeter joints where frames meet the structure and cladding panel joints that have opened up, on coping and flashing joints, cladding panel joints and perimeter joints where frames meet the structure. Most enquiries from Midhurst start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Conversions around smaller places like Midhurst often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.

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

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them.

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.

Owners, agents and contractors

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Quoting for work in Midhurst

To price the job, we consider:

  • Whether the work must be split into stages
  • Removal of failed or old sealant
  • The product specified
  • Backing rod, priming and other preparation

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Details that help us quote

A good diagnosis starts with the right details. Let us know:

  • Rough lengths or quantities, or drawings if you have them
  • Whether an asbestos survey exists
  • Any specification or named product
  • Access details, including height

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to call the office on 01277 525 020 or email the details over.

Facades, frames and programmes in Midhurst

There are several hotels within about 2 miles of Midhurst. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Central London is about 45 miles from Midhurst. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.

On a healthcare site such as Midhurst Community Hospital (0.8 miles north-east of Midhurst), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For a contractor at a hotel such as The Spread Eagle Hotel (less than half a mile north-east of Midhurst), the mastic often has to be finished before a reopening date. For contractors refurbishing units at places like Midhurst Business Centre (less than half a mile west of Midhurst), the mastic covers cladding panels, roller-door and window perimeters.

Midhurst is about 8 miles east of Petersfield, in West Sussex.

Why deal with it now?

Every shower drives water through a split perimeter bead. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing early costs far less than repairing what the water reaches. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

Your questions answered

Is Midhurst too far out for you?

No. Places such as Midhurst are covered as much as the big towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you take on a job at a hospital such as Midhurst Community Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

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.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Should we check old sealant for asbestos?

It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder. If asbestos is suspected, work stops until it is tested.

Do you use silicone for external joints?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them, and we work to what is specified.

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Investigate damp beside windows promptly
  • Ask about asbestos in pre-2000 mastic
  • Keep sills, gutters and drainage paths clear
  • Never let anyone seal over old sealant

Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. What matters most for a job in Midhurst is a clear list of what needs doing. You’ll then get a fixed price for the work.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

What we need from you

  • Tell us what induction or permit system the site runs
  • Point out any areas we must not close
  • Point out parking and an unloading spot
