Facade sealing for Freemantle sites

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

Why deal with it now?

Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

Access often affects the price as much as the sealing: 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?

  • Public liability insurance in place
  • 12-month guarantee on workmanship
  • Colours chosen to suit frames, cladding or finishes where possible
  • Fixed quotes based on photos, drawings or a visit

How we handle facade sealing in Freemantle

We don’t install glazing systems or replace glass. 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 new sealant peeling off old mastic and old perimeter mastic that has dried out, we can help, on perimeter joints where frames meet the structure, shopfront frames and window and door perimeters alike. Whoever orders the work in Freemantle, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Building work in places the size of Freemantle is normally small-scale: a handful of new houses, barn conversions, a school or hall extension. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Questions about Freemantle

Can you work at a site such as Liners Industrial Estate, by Freemantle?

Yes, sites like Liners Industrial Estate are within our area, along with the rest of Freemantle. Photos and a short description are enough for a first look.

Is a hospital such as Royal South Hants Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you run new sealant over the existing bead?

No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

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.

Can you quote from photos?

That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

Keeping the joints sound

Regular inspection catches problems early. Specifically:

  • Ask about asbestos in pre-2000 mastic
  • Record the product and colour used on each elevation
  • Keep pressure washers away from fresh sealant
  • Insist on a full cut-out when joints are renewed

Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal without guesswork.

Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading behind the facade.

When something else is needed

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Damaged frames that need replacing
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Arranging specialist high-level access, which is planned with the client

If in doubt, speak to us on 01277 525 020 or email the details over and we’ll say what we think before you book.

What we seal

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

Facades, frames and programmes in Freemantle

Freemantle lies within about 1 mile of the sea. Coastal exposure means perimeter and cladding joints work harder than on an inland job, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. A 2-mile radius around Freemantle takes in plenty of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

New wings at hospitals like Royal South Hants Hospital (to the east of Freemantle) bring long runs of window and panel joints to seal. Hotels like The Bedford Hotel (0.9 miles east of Freemantle) rarely close for long, so refurbishment mastic is phased floor by floor. For contractors at a college like Richard Taunton Sixth Form College, which lies north of Freemantle, perimeters and internal sealant are timed for the holidays.

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. What matters most for a job in Freemantle is a clear list of what needs doing, so send photographs of each area. You’ll then get a fixed price for the work.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Send any specification or drawings in advance
  • Tell us which areas need to stay in use

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, 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.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Surface by 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 to the correct depth.

Perimeter joints at frames and structure

Perimeter joints at frames often show their age first. We cut them out, prepare both faces and reseal to the specification with a product suited to glazing perimeters.
