Facade sealing for businesses in Waterham

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Facade sealing in Waterham, done properly

Facade sealants sit in the sun, rain and frost every day. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. If you are dealing with cladding panel joints that have opened up and perimeter joints where frames meet the structure, we can help, on window and door perimeters, shopfront frames and cladding panel joints alike. Looking for mastic applicators who cover Waterham? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

For a site near Waterham, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we’ll quote to suit.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

When it isn’t the sealant

Being straight saves everyone time. Fresh joints won’t solve:

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

If in doubt, call 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Joints and surfaces we work on

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

Do you need facade sealing in Waterham?

New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, so the new bead peels away within a season or two.

It’s worth sending us details if you spot any of the following:

  • Air leaks through failed facade joints
  • Leaks at window and door perimeters
  • Gaps between rainscreen or cladding panels
  • Unsightly perimeter sealant on a visible elevation

For contractors on a campus like University of Kent, 4.3 miles to the south-east of Waterham, facade and perimeter sealing has to fit around students and term dates.

Before you book anyone

  • Will RAMS and insurance details be available?
  • Their pre-qualification and accreditations
  • Whether old or failed sealant will be cut out, not overlaid
  • Their public liability cover

Choosing a commercial sealant contractor

On site: what to expect

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Waterham are usually planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We plan access and the order of elevations with the client.
  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. Once signed off, the work carries our 12-month guarantee.

Before we start on site

  • Confirm the product named in the specification
  • Send your site hours and access windows
  • Point out parking and an unloading spot

Waterham: questions and answers

Can work at a site such as University of Kent fit around teaching?

Yes. If you need card details for site access, tell us and we’ll confirm them 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, and bigger or more complex jobs usually get a visit.

How long does a job like this take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

Building and refurbishing in Waterham

Waterham is within about 2 miles of the coast. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Waterham is about 48 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.

New wings at hospitals like Whitstable and Tankerton Hospital, 4 miles to the north-east of Waterham, bring long runs of window and panel joints to seal. When a school such as Hernhill Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Waterham is about 3 miles south-west of Whitstable, in Kent. Looking for facade sealing in Waterham? We can help. Waterham is one of 931 places in Kent on our list for facade joints. Our London page has more on work in that area (48 miles or so).

Doing it in-house

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

How the job changes by surface

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building and need a durable external sealant.

Perimeter joints at frames and structure

Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint, not the framing or glazing itself.

Maintenance after handover

Problems stay small when the joints are checked regularly. Specifically:

  • Share access with other external trades
  • Insist on a full cut-out when joints are renewed
  • Avoid harsh cleaners on facade sealant
  • Inspect facade joints on a regular cycle

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly with a compatible product.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
