Facade sealing in Kingston

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure for clients around Kingston. Where sealant is the specified fix, we also take on coping and flashing joints. We work on coping and flashing joints, perimeter joints where frames meet the structure and window and door perimeters, and the usual reasons a site gets in touch are hard, chalky sealant that no longer flexes and failed seals around shopfront and entrance frames. Whoever orders the work in Kingston, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Around smaller places like Kingston, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

New build and refits around Kingston

The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. Kingston lies roughly 57 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.

When a school such as Barham Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Extensions at sites like Kent and Canterbury Hospital (4.2 miles north-west of Kingston) normally sit beside working departments, and the mastic follows strict access rules. On a campus such as University for the Creative Arts, 4.6 miles north-west of Kingston, new teaching buildings and residences are normally built and refurbished around the academic year.

Kingston is about 5 miles south-east of Canterbury, in Kent. Anywhere in CT4, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 931 places across Kent fall within our area, Kingston among them. There’s a separate page for London, about 57 miles away.

We take on facade joints across the CT4 postcode area, for business premises of every kind.

What affects the price in Kingston

Each job is priced on its own details. The main factors are:

  • Induction, permit and paperwork requirements
  • Distance, for remote addresses
  • Whether the work must be split into stages
  • Access and working height

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Before you send an enquiry

A few photos plus some basic facts will normally do. It helps to include:

  • A wide shot and a close-up of the area
  • The asbestos register, for older buildings
  • The postcode of the building
  • What the building is and how it’s used

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or email a schedule or drawings.

Honest limits

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Damaged frames that need replacing
  • Arranging specialist high-level access, which is planned with the client
  • Installing or repairing glazing systems

If you are not sure, just call the office on 01277 525 020 or use the quote form and we’ll give you a straight answer.

What we seal

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

Diagnose, treat, sign off

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Smaller jobs around Kingston can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Point out parking and an unloading spot
  • Send asbestos survey details if the building is pre-2000
  • Tell us which areas need to stay in use

Advice

FAQs: Kingston

Can work at a site such as University for the Creative Arts fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can you work on a hospital site such as Kent and Canterbury Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Does weather matter for sealant work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

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.

Can you work while the building is occupied?

Usually, yes. Phased work can be planned so areas stay in use.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we’ll price the work to it.

Maintenance after handover

Problems stay small when the joints are checked regularly. In particular:

  • Record the product and colour used on each elevation
  • Check that rainwater leaves the facade the way it was designed to
  • Investigate damp beside windows promptly
  • Avoid patch repairs on failed facade joints

Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed rather than sitting against the joints.

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

Why act early in Kingston

Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. One visit to deal with every failing joint makes more sense than several trips to a place like Kingston, rather than one at a time. Send photos of each area and we’ll quote for the lot.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
