Facade sealing for commercial buildings in Bircholt Forstal

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip. If the evidence points away from the sealant, we say so before quoting. We work on cladding panel joints, perimeter joints where frames meet the structure and coping and flashing joints, and the usual reasons a site gets in touch are gaps between rainscreen or cladding panels and damp patches beside frames after rain. Searching for sealant specialists in Bircholt Forstal? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Construction in and around smaller places such as Bircholt Forstal is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Doing it in-house

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

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 where general trades tend to cut corners.

When something else is needed

We check first that sealant really is the fix. It won’t put right:

  • Providing access systems for the work
  • Replacing glass or failed glazing units
  • Cracked or spalling substrates that need repair before sealing

If you’re not sure, just ring 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

Surfaces we seal

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

On site: what to expect

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Jobs in and around smaller places like Bircholt Forstal are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  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. Once signed off, the work carries our 12-month guarantee.

Before we start on site

  • Move anything stored against the joints
  • Tell us your opening times and when work is allowed
  • Confirm the product named in the specification

Mastic packages on Bircholt Forstal sites

Rainfall across the South East, Bircholt Forstal included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team. Bircholt Forstal lies roughly 53 miles out from central London. 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.

Hospital estates such as William Harvey Hospital (Ashford), 2.6 miles to the west of Bircholt Forstal, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. School extensions, at buildings such as Brabourne Church of England Primary School, typically run to the summer holidays, mastic included.

Bircholt Forstal is about 5 miles east of Ashford, in Kent. Businesses, contractors and managing agents in Bircholt Forstal can call on us for facade joints. We work across 931 places in Kent, large and small. Brighton is covered too, some 52 miles away.

What we are called out for in Bircholt Forstal

Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.

Most enquiries start with something like this:

  • Unsightly perimeter sealant on a visible elevation
  • Cold air coming in at window perimeters
  • Cladding panel joints that have opened up
  • Leaks at window and door perimeters

Older buildings in the area around Bircholt Forstal, such as Westenhanger Castle, 3.6 miles to the south-east of Bircholt Forstal, need care when sealed: the product has to suit soft or historic materials.

Questions about Bircholt Forstal

Is a hospital such as William Harvey Hospital (Ashford) somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Bircholt Forstal off your patch?

Not at all. Bircholt Forstal is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

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.

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Yes. Our applicators hold CSCS cards.

Do you offer coloured sealant?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
