Facade sealing in Magham Down

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

After the work

Once the work is signed off, a little attention goes a long way:

  • Investigate damp beside windows promptly
  • Check the asbestos register before old mastic is disturbed
  • Walk the elevations once or twice a year
  • Keep pressure washers away from fresh sealant

Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; record the locations.

Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones inside the building.

Facade sealing in Magham Down, done properly

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on offices, blocks and industrial units. Where sealant is the specified fix, we also take on coping and flashing joints. If you have hard, chalky sealant that no longer flexes and perimeter joints where frames meet the structure, we can help, whatever the surface. Searching for sealant specialists in Magham Down? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

For a site near Magham Down, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we’ll quote to suit.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Work for main contractors and building owners

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Magham Down can sit alongside others in a wider programme across East Sussex.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a building around Magham Down, 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. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Have the specification and drawings to hand
  • For older buildings, check the asbestos register before work

Getting a fixed quote

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Advice

Should maintenance staff do it?

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.

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Honest limits

Being straight saves everyone time. Fresh joints won’t solve:

  • Damaged frames that need replacing
  • Joints whose design needs changing by the specifier
  • Damp caused by condensation inside the building

If in doubt, speak to us on 01277 525 020 or send photos by email and we’ll say what we think before you book.

Where we work in Magham Down

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

Leave it or put it right?

Failed joints let in more than water: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Halls, stores and units around places like Magham Down may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Pricing facade joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Magham Down: questions and answers

Is Magham Down too small for you to travel to?

Not at all. Magham Down is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Will you take on work at estates like Station Road Industrial Estate, close to Magham Down?

Yes, sites like Station Road Industrial Estate are within our area, along with the rest of Magham Down. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Do you offer coloured sealant?

That depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.

Should we check old sealant for asbestos?

It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register. If asbestos is suspected, work stops until it is tested.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you guarantee your work?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

Contractors’ notes for Magham Down

Magham Down is about 46 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. Magham Down sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.

With historic properties like Horselunges Manor (1.7 miles west of Magham Down) in the area, refurbishment work often meets old masonry that needs compatible sealants. New wings at hospitals like Amberstone Hospital (to the west of Magham Down) bring long runs of window and panel joints to seal. Units on estates such as Station Road Industrial Estate (to the south-west of Magham Down) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
