Facade sealing in Cliddesden

Managing agents and owners in Cliddesden ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. We work on window and door perimeters, shopfront frames and stone and brick facade joints, and the failures we are asked to look at most are draughts around frames and panels and old perimeter mastic that has dried out. Most enquiries from Cliddesden 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.

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

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

After the work

For the best life from the joints:

  • Brief window cleaners about newly sealed joints
  • Walk the elevations once or twice a year
  • Share access with other external trades
  • Investigate damp beside windows promptly

Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly using a matching sealant.

Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and limits disruption.

Leave it or put it right?

The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. For buildings around smaller places like Cliddesden, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Do you need facade sealing in Cliddesden?

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained and rips when the facade moves.

What tends to prompt an enquiry:

  • Hard, chalky sealant that no longer flexes
  • Gaps between rainscreen or cladding panels
  • Facade joints cracked through the middle
  • Cold air coming in at window perimeters

For contractors at a college like Queen Mary's College, 1.3 miles to the north of Cliddesden, perimeters and internal sealant are timed for the holidays.

Does your area include sites such as Viables Business Park, near Cliddesden?

Yes. Our area takes in Cliddesden and its surroundings, with estates and business parks such as Viables Business Park included. A few photographs and the unit address let us price the work.

Is a hospital such as Basingstoke and North Hampshire 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.

Can the building stay open while you work?

In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Do you need to see the site first?

It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

What about RAMS and site documents?

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

Do you cover Cliddesden?

Yes. We take on work across Cliddesden, and the same phone number covers every area.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Facades, frames and programmes in Cliddesden

At about 47 miles from central London, Cliddesden is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand. Cliddesden has several hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

Extensions at sites like Basingstoke and North Hampshire Hospital (to the north of Cliddesden) usually sit beside working departments, and the mastic follows strict access rules. When units on a site such as Viables Business Park (0.6 miles north of Cliddesden) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Different surfaces, different methods

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. We seal those perimeter joints.

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Smaller jobs around Cliddesden can be grouped with others nearby. 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. 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. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  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.
