Facade sealing in Shalfleet, done properly

Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. If you have failed sealant on precast panel joints and facade joints cracked through the middle, we can help, whatever the surface. Most enquiries from Shalfleet 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.

Around smaller places like Shalfleet, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When it isn’t the sealant

Some faults sit outside our scope, and we say so rather than covering them up:

  • Work on the window or framing system itself
  • Specialist high-level access methods
  • Movement beyond what any sealant can handle

Not sure which it is? You can ring 01277 525 020 or use the quote form and we will tell you honestly.

Joints and surfaces we work on

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

Commercial clients in Shalfleet

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Shalfleet. One quote can cover more than one site, which keeps the paperwork simple.

After the work

After handover, these steps help:

  • Check that rainwater leaves the facade the way it was designed to
  • Combine resealing with other works that need access
  • Avoid harsh cleaners on facade sealant
  • Note when each elevation was last resealed

Keep a note of which product went in and when. Future work can then match the product and colour across the elevation.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and work stops until it’s tested if it’s suspected.

Shalfleet: questions and answers

Our building in Shalfleet is near the coast: does that change the sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Is a smaller place like Shalfleet outside your area?

Not at all. Shalfleet is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do you install glazing systems?

No. A glazing contractor handles that. What we seal are the joints around frames and panels.

Is the work guaranteed?

Yes. Workmanship is guaranteed for 12 months on every job.

What hours do you work?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Can you work on upper floors?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you’re arranging and any site restrictions, and we will price the work around it.

Which sealant do you use on facades?

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.

On site: what to expect

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. Smaller jobs around Shalfleet can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First we review photographs, 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. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

What we need from you

  • Let us know about inductions and permits
  • Make sure the joints can be reached
  • Send any specification or drawings in advance

Advice

Building and refurbishing in Shalfleet

Shalfleet lies within about 2 miles of the sea. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.

For contractors refurbishing units at places like Porchfield Business Park, which lies north-east of Shalfleet, the mastic covers cladding panels, roller-door and window perimeters. For contractors at a school such as Shalfleet Church of England Primary School, sealing has to be finished before term starts. On a healthcare site such as St Mary's Hospital, 5.2 miles east of Shalfleet, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Shalfleet is about 5 miles west of Newport, in the Isle of Wight. Shalfleet sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Shalfleet is one of 125 places in the Isle of Wight on our list. There’s a separate page for Southampton, about 15 miles away.

Surface by surface

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building, so preparation and product choice matter.

Precast concrete panels

Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod.

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
