Diagnose, treat, sign off

In a busy building, 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 handed back before the next one starts.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.

Advice

Facade sealing for commercial buildings in Langdon Hills

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear. The enquiries we see most involve weathered joints at frame-to-structure perimeters and old perimeter mastic that has dried out, across perimeter joints where frames meet the structure, coping and flashing joints and shopfront frames. Searching for sealant specialists in Langdon Hills? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Around places like Langdon Hills, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Honest limits

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Work on the window or framing system itself
  • Specialist high-level access methods
  • Movement beyond what any sealant can handle

Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we will tell you honestly before you book.

Facade sealing around Langdon Hills: points for this area

Langdon Hills is about 23 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. Langdon Hills is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.

Further education sites such as Performers College, 2.3 miles to the south-east of Langdon Hills, are extended and refurbished from time to time, with mastic often programmed into the summer break. For a contractor working at a hospital such as Basildon University Hospital, 1.3 miles east of Langdon Hills, perimeter and facade sealing is planned around patients and deliveries.

Langdon Hills is about 2 miles south-west of Basildon, in Essex. Businesses, contractors and managing agents in Langdon Hills can call on us for facade joints, as part of our coverage of Essex.

Leave it or put it right?

The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Different surfaces, different methods

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building.

Brick and stone facades

Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one.

Signs you need facade sealing in Langdon Hills

When the sealant tears down its centre, it has normally been asked to move more than it can. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

Clients usually get in touch after noticing one or more of the following:

  • Hard, chalky sealant that no longer flexes
  • Patch repairs that keep failing
  • Leaks at window and door perimeters
  • Draughts around frames and panels

When a school such as Lincewood Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Questions to ask before you appoint anyone

Questions we’re asked in Langdon Hills

Can work at a site such as Performers College fit around teaching?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is a smaller place like Langdon Hills outside your area?

No. Places such as Langdon Hills are covered as much as the big towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Are you CHAS accredited?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Can weather delay the job?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Will you come and look before quoting?

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

Will you quote for a small job?

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

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Quoting for work in Langdon Hills

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Any access equipment needed

What to include in your enquiry

  • Drawings or a marked-up plan, if available
  • The product your specification calls for
  • What the building is and how it’s used
