Facade sealing for commercial buildings in Shermanbury

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters. If you have perimeter joints where frames meet the structure and weathered facade joints that have lost their grip, we can help, on shopfront frames, window and door perimeters and stone and brick facade joints alike. Most enquiries from Shermanbury start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Construction in and around smaller places such as Shermanbury is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Joints whose design needs changing by the specifier
  • Specialist high-level access methods
  • Replacing glass or failed glazing units

If you are not sure, just speak to us on 01277 525 020 or email us and we’ll give you a straight answer before you book.

Where we work in Shermanbury

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

When to bring in a specialist

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

On site: what to expect

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Shermanbury can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  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. 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. The completed runs are checked with you, then the 12-month guarantee applies.

What we need from you

  • Flag any permit to work we’ll need
  • Point out any areas we must not close

Keeping the joints sound

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

  • Plan facade sealing alongside redecoration
  • Report water ingress at frames as soon as it shows
  • Avoid patch repairs on failed facade joints
  • Avoid harsh cleaners on facade sealant

Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade rather than sitting against the joints.

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.

Common questions from Shermanbury clients

Is Shermanbury off your patch?

No. Places such as Shermanbury are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Is a hospital such as The Dene Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.

When can you be on site?

Give us your site hours and any access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

What type of sealant goes on window perimeters?

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.

Leave it or put it right?

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Leaks travel along the structure, often turning up far from the joint. Converted and older buildings near places like Shermanbury tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Why us?

  • Colour options checked against the specified product
  • 12 months’ guarantee on every job
  • Sealing commercial buildings since 2005
  • Joints cleaned back to sound surfaces

Facade sealing in Shermanbury: the local picture

Shermanbury sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack. Central London is about 38 miles from Shermanbury. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.

Extensions at sites like The Dene Hospital, 5.2 miles east of Shermanbury, usually sit beside working departments, and the mastic follows strict access rules. Recladding or extending a unit at a site like Star Trading Estate (to the west of Shermanbury) brings panel joints and frame perimeters into the programme. Projects at schools like Jolesfield CofE Primary School work to term dates, so mastic is programmed tightly.
