Facade sealing for Oakshott sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • Specialist high-level access methods
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Work on the window or framing system itself

Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we’ll tell you honestly.

About our facade sealing in Oakshott

Managing agents and owners in Oakshott ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. Site teams most often ask us about weathered facade joints that have lost their grip and damp patches beside frames after rain, on coping and flashing joints, perimeter joints where frames meet the structure and window and door perimeters. Whoever orders the work in Oakshott, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In the countryside around places like Oakshott, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

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.

Surface by surface

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.

Keeping the joints sound

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

  • Investigate damp beside windows promptly
  • Brief window cleaners about newly sealed joints
  • Walk the elevations once or twice a year
  • Confirm the survey covers external sealants in older buildings

Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.

Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down and cuts time on site.

What sets the cost

Quotes vary with the job. It mainly depends on:

  • Specialist products, such as fire-rated or hygienic sealants
  • The site’s rules and procedures
  • Quantities, in metres or numbers
  • Phasing around occupants

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What to include in your enquiry

Whether it’s one area or a whole building, the same details help:

  • What the building is and how it’s used
  • When you need the work done
  • Where the site is, with the postcode
  • Photos of the joints, close up and from further back

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

How a job runs

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before we move to the next. Rural sites near Oakshott may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

What we need from you

  • Flag any permit to work we will need
  • Share your working hours and any access restrictions
  • Share the asbestos register for older buildings

What we are called out for in Oakshott

The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.

Clients normally get in touch after noticing something like this:

  • Perimeter joints where frames meet the structure
  • Staining on stone next to old sealant
  • Patch repairs that keep failing
  • Cladding panel joints that have opened up

Extensions at sites like Petersfield Hospital, 2.9 miles to the south of Oakshott, normally sit beside working departments, and the mastic follows strict access rules.

What to look for in a quote

  • Their public liability cover
  • Will failed sealant be removed rather than covered?
  • Will RAMS and insurance details be available?
  • Whether their applicators hold CSCS cards
