Facade sealing near Bishopstoke

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Keeping the joints sound

To get the most from the new sealant:

  • Investigate damp beside windows promptly
  • Avoid patch repairs on failed facade joints
  • Keep pressure washers away from fresh sealant
  • Share access with other external trades

Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.

Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail.

About our facade sealing in Bishopstoke

A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces, often at around 2:1 width to depth, as the manufacturer advises. If you have discoloured or dirty facade joints and draughts around frames and panels, we can put it right, on perimeter joints where frames meet the structure, shopfront frames and cladding panel joints alike. Looking for mastic applicators who cover Bishopstoke? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

For a contractor on a smaller site near Bishopstoke, one mastic visit at the right stage saves return trips. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

General trades versus a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Questions about Bishopstoke

Can you work at a site such as Deacon Trading Estate, by Bishopstoke?

Yes. We cover Bishopstoke and the area around it, including industrial estates, business parks and retail parks such as Deacon Trading Estate. A few photos and the unit address let us price the work.

Could you schedule work at a campus like University of Southampton for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Are you fully insured?

Yes. We are fully insured, including public liability cover.

What type of sealant goes on window perimeters?

The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs typically get a visit.

Can you find out why a window is leaking?

Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all, and we’ll tell you which.

Surface by surface

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building and need a durable external sealant.

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. Loose coatings are cleaned back first, and areas needing repair are flagged.

Why deal with it now?

If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once, saving a second set-up. In a smaller place such as Bishopstoke, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Why appoint us

  • A fixed quote before work starts
  • Work to your specification and the manufacturer’s guidance
  • A Constructionline member, so easy to vet

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. Several jobs near Bishopstoke can be grouped on one trip. Mention the building’s opening times and we will work within them.

  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. The completed runs are checked with you, then the 12-month guarantee applies.

Getting the site ready

  • Have the specification and drawings to hand
  • Let us know about inductions and permits
  • Tell staff and tenants when we’ll be in

Advice

What sealant work can’t fix

Being straight saves everyone time. New sealant won’t cure:

  • Installing or repairing glazing systems
  • Arranging specialist high-level access, which is planned with the client
  • Water getting in through cracked render or porous masonry

If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think.

Joints and surfaces we work on

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

Facades, frames and programmes in Bishopstoke

Bishopstoke has several hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Bishopstoke is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

Further education sites such as Eastleigh College - Desborough Campus, 1.3 miles to the west of Bishopstoke, are extended and refurbished from time to time, with mastic often programmed into the summer break. New wings at hospitals like Wessex Hospital, 2.4 miles north-west of Bishopstoke, bring long runs of window and panel joints to seal. School extensions, at buildings such as Stoke Park Junior School, typically run to the summer holidays, mastic included.
