Facade sealing in Lordswood, done properly

We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause, but not always. If the evidence points away from the sealant, we say so before quoting. We work on shopfront frames, cladding panel joints and coping and flashing joints, and the usual reasons a site gets in touch are previous reseals run over old sealant and gaps between rainscreen or cladding panels. One point of contact handles commercial sealant work in Lordswood from the first photos to the final walk-round, for single jobs and planned programmes alike.

Building work in places the size of Lordswood is typically small-scale: a handful of new houses, barn conversions, a school or hall extension. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Building and refurbishing in Lordswood

A number of hotels sit less than 2 miles from Lordswood. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. The South East is one of the drier parts of the UK. 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.

When a school such as St Benedict's Catholic Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Extensions at sites like Spire Alexandra Hospital, 0.9 miles to the south-west of Lordswood, usually sit beside working departments, and the mastic follows strict access rules.

Lordswood is about 2 miles south of Chatham, in Medway. We send applicators to Lordswood for facade joints, handled exactly as we handle every other area. We work across 54 places in Medway, from busy centres to rural villages. Sites around London have their own page, about 30 miles away.

We take on facade joints across the ME5 and ME7 postcode area. Streets here include Hall Road, Rover Road and Gould Road, and sites on any of them can send details for a fixed quote. If your building is just outside Lordswood, we cover Lidsing (1 mile south-east), Walderslade (1 mile west), Dunn Street (1 mile south-east), Bredhurst (1 mile east) and Hempstead (2 miles north-east). Further afield, our area takes in Gillingham (3 miles north-east), Rochester (4 miles north-west), Rainham (3 miles north-east), Strood (5 miles north-west), Twydall (3 miles north-east) and Hoo St Werburgh (6 miles north). Among the larger centres in Medway is Lordswood, and we take on facade joints for its commercial and public buildings.

Keeping the joints sound

After handover, these steps help:

  • Clear debris that holds water against joints
  • Note when each elevation was last resealed
  • Investigate damp beside windows promptly
  • Inspect facade joints on a regular cycle

Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade rather than sitting against the joints.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and work stops until it’s tested if it’s suspected.

Common questions from Lordswood clients

Is a hospital such as Spire Alexandra Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Is Lordswood too far out for you?

No. Places such as Lordswood are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

How much does the work cost?

There isn’t a price list, because every site is different. Send photographs or drawings and we will price it at a fixed figure.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Will you check whether the sealant is causing the leak?

Yes. Photos help, and you can ring 01277 525 020 or email the details over to arrange a visit. Many frame leaks are sealant failures, though not all.

What type of sealant goes on window perimeters?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them, and we work to what is specified.

Can you quote from photographs?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. If neighbouring businesses or buildings around Lordswood need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Getting the site ready

  • Share the asbestos register for older buildings
  • Point out any areas we must not close
  • Let us know about inductions and permits

Advice

Surface by surface

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather.

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.

What sealant work can’t fix

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

  • Movement beyond what any sealant can handle
  • Providing access systems for the work
  • Water getting in through cracked render or porous masonry

If in doubt, phone 01277 525 020 or email the details over and we’ll say what we think.

Where we work in Lordswood

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

What we’re called out for in Lordswood

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. Without rod or bond-breaker tape, the bead is held back and rips when the facade moves.

Look out for the following:

  • Perimeter joints where frames meet the structure
  • Old perimeter mastic that has dried out
  • Air leaks through failed facade joints
  • Leaks at window and door perimeters

Units on estates such as Lordswood Industrial Estate (0.5 miles south of Lordswood) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

What to look for in a quote

  • Whether primer will be used where the manufacturer specifies it
  • Are they CHAS accredited or on Constructionline?
  • Can the work be phased to keep areas open?
  • Proof of insurance

How to choose a sealant contractor

Why deal with it now?

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 early costs far less than repairing what the water reaches. In a smaller place such as Lordswood, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Whether it’s a single area or a whole estate, the same things set the price: 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.

Why us?

  • A Constructionline member, so easy to vet
  • Coloured sealants to suit the setting, where available
  • Over 20 years of commercial sealing
  • Specification-led, product-correct work
