Facade sealing in Park Gate

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

Maintenance after handover

To get the most from the new sealant:

  • Keep the sealant details on the building file
  • Clear debris that holds water against joints
  • Confirm the survey covers external sealants in older buildings
  • Never let anyone seal over old sealant

Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; record the locations.

Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Facade sealing for commercial buildings in Park Gate

Managing agents and owners in Park Gate ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. We work on perimeter joints where frames meet the structure, cladding panel joints and coping and flashing joints, and what we are called in for most is old perimeter mastic that has dried out and discoloured or dirty facade joints. One point of contact handles commercial sealant work in Park Gate from the first photographs to the final walk-round, whether it’s one building or several.

Around smaller places like Park Gate, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

A 12-month guarantee applies to all our work. Should something we installed fail, call the office on 01277 525 020 or email us and we will come back to it.

When something else is needed

Some faults sit outside our scope, and we say so rather than covering them up:

  • Providing access systems for the work
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Render or concrete edges that have broken away

If you’re not sure, just ring 01277 525 020 or use the quote form and we will give you a straight answer.

Where we work in Park Gate

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

Diagnose, treat, sign off

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Jobs in and around smaller places like Park Gate are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Confirm the product named in the specification
  • Tell staff and tenants when we will be in
  • Arrange parking or a loading space

Advice

Leave it or put it right?

Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds and avoids repeat call-outs. One visit to deal with every failing joint makes more sense than several trips to a place like Park Gate. Send photographs of each area and we will quote for the lot.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Why us?

  • Products installed to the manufacturer’s instructions
  • Health and safety: CHAS accredited
  • Standard and matched colours in many product ranges
  • Public liability insurance in place

Your questions answered

Is a smaller place like Park Gate outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you take on a job at a hospital such as Fareham Community Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Should we check old sealant for asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed, and if anything is suspected, we stop until it’s tested. We don’t remove asbestos-containing materials.

Is any job too small?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Different surfaces, different methods

Window and door perimeters

Frame materials vary, and so does the preparation. Primer goes on where the manufacturer specifies it for that substrate.

Render and coated surfaces

Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

Facades, frames and programmes in Park Gate

Park Gate lies within about 3 miles of the sea. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so joint design, primers and product choice deserve extra care. The area within 2 miles of Park Gate holds several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

Hotels like Solent Hotel and Spa (to the north-east of Park Gate) rarely close for long, so refurbishment mastic is phased floor by floor. School extensions, at buildings such as Park Gate Primary School, usually run to the summer holidays, mastic included. New units and refits on sites such as Park Gate Business Centre, under half a mile to the north of Park Gate, need their panel and perimeter joints sealed to the specification.
