Facade sealing near Bosham

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

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

How we handle facade sealing in Bosham

Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds, using sealants classified for facade or glazing use. We work on window and door perimeters, perimeter joints where frames meet the structure and coping and flashing joints, and what we are called in for most is previous reseals run over old sealant and discoloured or dirty facade joints. Facilities teams, main contractors and managing agents in Bosham tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Around smaller places like Bosham, building work typically 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.

A 12-month guarantee applies to all our work. If an installation problem shows up, ring 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

What happens if it’s left?

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. One visit to deal with every failing joint makes more sense than several trips to a place like Bosham, rather than one at a time. Photos of every joint help us quote for the whole job.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Sites and facades in and around Bosham

Bosham sits close to the coast, within about 2 miles. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. Several hotels sit less than 2 miles from Bosham. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.

New wings at hospitals like St Richard's Hospital, 3.8 miles east of Bosham, bring long runs of window and panel joints to seal. On a campus such as University of Chichester, which lies east of Bosham, new teaching buildings and residences are typically built and refurbished around the academic year.

Bosham is about 3 miles west of Chichester, in West Sussex. Businesses, contractors and managing agents in Bosham can call on us for facade joints, as part of our coverage of West Sussex.

Signs you need facade sealing in Bosham

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

Site and facilities staff are often the first to spot these:

  • Perimeter sealant that has split or peeled away
  • New sealant peeling off old mastic
  • Gaps between rainscreen or cladding panels
  • Draughts around frames and panels

Recladding or extending a unit at a site like Southfield Industrial Park. (under half a mile north of Bosham) brings panel joints and frame perimeters into the programme.

Choosing a commercial sealant contractor

Bosham: questions and answers

Does your area include sites such as Southfield Industrial Park., near Bosham?

Yes, sites like Southfield Industrial Park. Are within our area, along with the rest of Bosham. Photos and a short description are enough for a first look.

Can you work on a hospital site such as St Richard's Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you install glazing systems?

No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

Can you just add new sealant on top?

No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.

Can you find out why a window is leaking?

Yes. Photos help, and you can ring 01277 525 020 or use the quote form to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we’ll tell you which.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Commercial clients in Bosham

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Bosham. One quote can cover more than one site, so there’s one set of paperwork to deal with.

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

From enquiry to sign-off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a building around Bosham, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  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

  • Agree which areas must stay open
  • Confirm the product named in the specification
  • Arrange parking or a loading space

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

  • How much existing material needs removing
  • Phasing around occupants
  • Site requirements such as inductions and permits
  • How accessible the joints are

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

What to include in your enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Rough lengths or quantities, or drawings if you have them
  • Whether the building will be occupied during the work
  • Photos of the joints, close up and from further back
  • Any specification or named product

Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, speak to us on 01277 525 020 or email us.
