Facade sealing near Culmers

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Render or concrete edges that have broken away
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Work on the window or framing system itself

Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

What we seal

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

Facade sealing in Culmers, done properly

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. If you have weathered joints at frame-to-structure perimeters and damp patches beside frames after rain, we can put it right, on shopfront frames, cladding panel joints and perimeter joints where frames meet the structure alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Culmers is the same: the right product in a properly prepared joint.

Around smaller places like Culmers, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Our workmanship is guaranteed for 12 months, in Culmers as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What the job involves on each surface

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first.

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather.

What we’re called out for in Culmers

Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.

What tends to prompt an enquiry:

  • Damp patches beside frames after rain
  • Hard, chalky sealant that no longer flexes
  • Gaps between rainscreen or cladding panels
  • Staining on stone next to old sealant

Hospital estates such as Whitstable and Tankerton Hospital (5.5 miles north-east of Culmers) 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.

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • What site paperwork they can supply
  • Can the work be phased to keep areas open?
  • Do they follow the manufacturer’s priming guidance?

How to choose a sealant contractor

What affects the price in Culmers

Before we quote, we look at:

  • Whether old sealant has to be cut out first
  • The site’s rules and procedures
  • Location, for remote and island sites
  • Access and working height

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 once you have the details.

Details that help us quote

It doesn’t need to be a full survey. These details are enough to start:

  • How the joints are reached, and at what height
  • Specification clauses that apply
  • Asbestos survey details if the building is older
  • Any dates the work must fit around

For a fixed quote, call 01277 525 020 or email a schedule or drawings with the site address and an outline of the work. Our quote form is another easy route.

Sites and facades in and around Culmers

Culmers sits close to the coast, within about 3 miles. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so we check the specified product suits the exposure before the first bead. Rainfall across the South East, Culmers 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.

School extensions, at buildings such as Graveney Primary School, usually run to the summer holidays, mastic included. New units and refits on sites such as Waterham Business Park (1.7 miles east of Culmers) need their panel and perimeter joints sealed to the specification.

How a job runs

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Culmers, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Getting the site ready

  • Point out any areas we must not close

FAQs: Culmers

Does your area include sites such as Waterham Business Park, near Culmers?

Yes. Estates, retail parks and business parks around Culmers, Waterham Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Do you take on work at healthcare sites like Whitstable and Tankerton 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.

Do you install glazing systems?

No. That work needs a glazing specialist. What we seal are the joints around frames and panels across the facade.

Which sealant do you use on facades?

The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can you send site paperwork?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Culmers can sit alongside others in a wider programme across Kent.
