When something else is needed

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

  • Specialist high-level access methods
  • Render or concrete edges that have broken away
  • Movement beyond what any sealant can handle

If you’re not sure, just give us a call on 01277 525 020 or email the details over and we will give you a straight answer.

Joints and surfaces we work on

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

How we handle facade sealing in East Marden

Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. If you are dealing with air leaks through failed facade joints and perimeter joints where frames meet the structure, we can put it right, on shopfront frames, coping and flashing joints and cladding panel joints alike. Most enquiries from East Marden start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like East Marden, building work normally 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 is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Leave it or put it right?

Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing now costs less than repairing interiors later. For buildings around smaller places like East Marden, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Diagnose, treat, sign off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Jobs in and around smaller places like East Marden are typically planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

What we need from you

  • Tell staff and tenants when we’ll be in
  • Share your working hours and any access restrictions
  • Have the specification and drawings to hand

Facade sealing around East Marden: what changes locally

East Marden sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. Central London is about 51 miles from East Marden. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.

With historic properties like Uppark (2.6 miles north-west of East Marden) in the area, refurbishment work often meets old masonry that needs compatible sealants. Sites around East Marden get mastic sealed to the drawings and the programme, nothing improvised.

East Marden is about 6 miles north-east of Emsworth, in West Sussex. Anywhere in PO18, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. East Marden is one of 373 places in West Sussex on our list for facade joints. Our Portsmouth page has more on work in that area.

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Brief window cleaners about newly sealed joints
  • Record the product and colour used on each elevation
  • Keep sills, gutters and drainage paths clear
  • Ask about asbestos in pre-2000 mastic

After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

Questions we are asked in East Marden

Is a smaller place like East Marden outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

What paperwork can you provide for a job in East Marden?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also give us a call on 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.

Do we need an asbestos check before resealing?

In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first. We don’t remove asbestos-containing materials.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Different surfaces, different methods

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them.

Window and door perimeters

Aluminium, PVC-U and timber frames each have their own preparation needs. We clean and prime to the sealant maker’s guidance for each surface.
