Facade sealing for commercial buildings in Lanham Green

We don’t install glazing systems or replace glass. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters, using sealants classified for facade or glazing use. We work on window and door perimeters, coping and flashing joints and perimeter joints where frames meet the structure, and the failures we are asked to look at most are draughts around frames and panels and gaps between rainscreen or cladding panels. Whether you call it commercial sealant work, mastic application or joint sealing, in Lanham Green it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Conversions of older rural buildings near smaller places such as Lanham Green bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.

A 12-month guarantee applies to all our work. If an installation problem shows up, phone 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Damp caused by condensation inside the building
  • Specialist high-level access methods
  • Replacing glass or failed glazing units

If you’re not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer.

Joints and surfaces we work on

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

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

What happens if it’s left?

Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. One visit to deal with every failing joint makes more sense than several trips to a place like Lanham Green, rather than one at a time. Send photographs of each area and we will quote for the lot.

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

Why appoint us

  • Old sealant cut out, never sealed over
  • One contact handling all your sites
  • Coloured sealants to suit the setting, where available
  • RAL and finish matching where the product range allows

Maintenance after handover

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

  • Clear debris that holds water against joints
  • Combine resealing with other works that need access
  • Avoid harsh cleaners on facade sealant
  • Avoid patch repairs on failed facade joints

Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.

Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in instead of after the damage.

Commercial clients in Lanham Green

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Lanham Green: questions and answers

Is Lanham Business Park, near Lanham Green, within your area?

Yes, sites like Lanham Business Park are within our area, along with the rest of Lanham Green. To start, just ring 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Can you work on a hospital site such as Braintree Community Hospital?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

How long does a job like this take?

It depends on the scope, but the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building. For bigger or phased jobs, we will set out a timescale with the quote.

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 we need an asbestos check before resealing?

For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder. If asbestos is suspected, work stops until it is tested.

Do you provide access for facade work?

That comes down to the access arranged for the job. When you ring 01277 525 020 or use the quote form, describe the access, and we will plan the work with you.

Is any job too small?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Building and refurbishing in Lanham Green

Rainfall across the South East, Lanham Green included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager. At about 39 miles from central London, Lanham Green is within reach of the capital. 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.

When a school such as Cressing Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. When a college such as Braintree College, 2.8 miles to the north-west of Lanham Green, builds or refurbishes, the mastic package usually has to fit around students and staff. When units on a site such as Lanham Business Park (to the north-west of Lanham Green) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Lanham Green is about 2 miles south-east of Braintree, in Essex. We cover commercial sites throughout Lanham Green, for single jobs and planned programmes alike. Across Essex, 644 places are covered, Lanham Green among them. Sites around London have their own page, about 39 miles away.
