Mastic sealing for commercial buildings in East Lockinge

Owners and agents typically inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. We work on external wall and movement joints, balcony and threshold joints and communal entrances and stairwells, and what we’re called in for most is occupiers reporting cold air round windows and open joints in brickwork or panels. Facilities teams, main contractors and managing agents in East Lockinge tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like East Lockinge, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

What sets the cost

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Travel to remote or island sites
  • Working within restricted access windows
  • Whether old sealant has to be cut out first
  • How accessible the joints are

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Sending details for a quote

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Anything awkward about access or site hours
  • Asbestos survey details if the building is older
  • What the building is and how it’s used
  • Rough lengths or quantities, or drawings if you have them

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

East Lockinge: questions and answers

Is Elms Farm Business Park, near East Lockinge, within your area?

Yes, sites like Elms Farm Business Park are within our area, along with the rest of East Lockinge. A few photographs and the unit address let us price the work.

Is a smaller place like East Lockinge outside your area?

No. Places such as East Lockinge are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Is mastic sealing guaranteed?

There is a 12-month guarantee on our workmanship and we hold public liability insurance.

Do you work for managing agents and housing associations?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.

Do you supply RAMS and insurance details?

We’re CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Do you need to see the site first?

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

Will you just go over the old sealant?

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

When something else is needed

Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:

  • Water coming in from the roof or rainwater goods
  • Leaks through the frame itself rather than the perimeter
  • Substrate edges that need repairing first

If you are not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Where we work in East Lockinge

  • External wall and movement joints
  • Communal entrances and stairwells
  • Window and door perimeters on blocks
  • Shopfronts below residential blocks
  • Communal kitchens and washrooms
  • Balcony and threshold joints

Aftercare for building managers

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

  • Have the asbestos survey to hand for older buildings
  • Make mastic part of routine maintenance checks
  • Share your contractor requirements early
  • Group repairs into a planned programme

Keep records of when each building was resealed. That makes future programmes easier to plan and gives you a history.

Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and saves internal repairs.

Why act early in East Lockinge

Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Converted and older buildings near places like East Lockinge tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

  • Standard and matched colours in many product ranges
  • Old sealant cut out, never sealed over

Things that typically lead to an enquiry:

  • The same joint failures repeated across a portfolio
  • Brittle perimeter mastic across a building
  • Draughts at frames across a block
  • Open joints in brickwork or panels

Trustees of buildings like Church of All Saints can bring frame and external mastic into a planned maintenance list.

What your quote should include

  • Will CSCS-carded applicators be on site?
  • Their plan for phasing and protecting the area
  • How the existing material will be dealt with
  • How long is the guarantee, and what does it include?
