Need facade sealing in Worthy Down?

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Quoting for work in Worthy Down

These are the things that shape the price:

  • Induction, permit and paperwork requirements
  • Working within restricted access windows
  • Removal of failed or old sealant
  • Quantities, in metres or numbers

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

What to include in your enquiry

We can often quote from photographs and a few details. Please tell us:

  • A wide shot and a close-up of the area
  • The site address and postcode
  • The asbestos register, for older buildings
  • Access details, including height

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

Facade sealing in Worthy Down, done properly

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, and we’ll fit the work around it. Site teams most often ask us about perimeter joints where frames meet the structure and leaks at window and door perimeters, across cladding panel joints, coping and flashing joints and shopfront frames. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Worthy Down is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places like Worthy Down, 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.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Questions about Worthy Down

Is a smaller place like Worthy Down outside your area?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Can you work on a hospital site such as Royal Hampshire County Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Are you CHAS accredited and on Constructionline?

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

Do you use silicone for external joints?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead.

How long before the joints can be used?

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

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

Leave it or put it right?

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Leaks travel along the structure. For buildings around smaller places like Worthy Down, 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.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

What you get with us

  • One phone line for London, the South East and Scotland
  • Joints cleaned back to sound surfaces
  • Health and safety: CHAS accredited
  • A Constructionline member, so easy to vet

Facades, frames and programmes in Worthy Down

The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager. Worthy Down lies roughly 60 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.

On a campus such as University of Winchester, which lies south of Worthy Down, new teaching buildings and residences are normally built and refurbished around the academic year.

How a job runs

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Smaller jobs around Worthy Down can be grouped with others nearby. You’ll have a fixed quote before work 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 both faces cleaned back.
  4. Primer is applied where the maker specifies 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

  • Send any specification or drawings in advance
  • Let building users know which areas are affected
  • Share your working hours and any access restrictions

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Related advice

How the job changes by surface

Window and door perimeters

Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch as the frame moves.

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod, primed where the maker specifies.

When to call us in Worthy Down

Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained and tears as the joint moves.

Things that usually lead to an enquiry:

  • Perimeter joints where frames meet the structure
  • Previous reseals run over old sealant
  • Draughts around frames and panels
  • Cladding panel joints that have opened up

Hospital estates such as Royal Hampshire County Hospital, 3.5 miles south of Worthy Down, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

What your quote should include

  • Are they CHAS accredited or on Constructionline?
  • Whether primer will be used where the manufacturer specifies it
  • Their approach to joint depth and backing
  • The terms of the workmanship guarantee
