About our facade sealing in Barkham

Facade sealants sit in the sun, rain and frost every day, and they wear out over time. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. Most enquiries involve draughts around frames and panels and leaks at window and door perimeters, across window and door perimeters, shopfront frames and perimeter joints where frames meet the structure. Whoever orders the work in Barkham, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Conversions of older rural buildings near smaller places such as Barkham bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Why it’s worth doing now in Barkham

If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice, saving a second set-up. For buildings around smaller places like Barkham, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

What you get with us

  • Fully insured, including public liability cover
  • Standard and matched colours in many product ranges
  • Failed material removed, not covered up
  • Matching to RAL references, product permitting

How the job changes by surface

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.

Window and door perimeters

Window and door perimeters make up most facade sealing work. A low-modulus, neutral-cure product suits most frame-to-wall joints.

Diagnose, treat, sign off

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. Jobs in and around smaller places like Barkham are normally planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Let us know about inductions and permits
  • Have the specification and drawings to hand
  • Point out any areas we must not close

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Common problems we fix in Barkham

New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead, so the new bead peels away within a season or two.

Clients typically get in touch after noticing one or more of the following:

  • Weathered facade joints that have lost their grip
  • Facade joints cracked through the middle
  • Damp patches beside frames after rain
  • Unsightly perimeter sealant on a visible elevation

For contractors on a campus like University of Reading - Whiteknights Campus, 4.2 miles north-west of Barkham, facade and perimeter sealing has to fit around students and term dates.

What to look for in a quote

  • Whether their applicators hold CSCS cards
  • Health and safety accreditation such as CHAS
  • What the guarantee covers, and for how long
  • Can the work be phased to keep areas open?

Questions to ask before you appoint anyone

Aftercare for building managers

After handover, these steps help:

  • Ask about asbestos in pre-2000 mastic
  • Avoid harsh cleaners on facade sealant
  • Investigate damp beside windows promptly
  • Insist on a full cut-out when joints are renewed

Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.

Coordinate facade sealing with other external works. One set-up for several trades saves money.

Facade sealing in Barkham: the local picture

Barkham is about 34 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme. Barkham is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.

For contractors at a school such as The Coombes Church of England Primary School, sealing has to be finished before term starts. Units on estates such as Molly Millars Lane Industrial Estate, 1.5 miles to the east of Barkham, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
