Facade sealing in Cliffs End

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

Facade sealing for commercial buildings in Cliffs End

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure. Where sealant is the specified fix, we also take on coping and flashing joints. The enquiries we see most involve gaps between rainscreen or cladding panels and leaks at window and door perimeters, on window and door perimeters, stone and brick facade joints and coping and flashing joints. For commercial sealant work in Cliffs End, you deal with one contact from quote to sign-off, whether it’s one building or several.

Construction in and around smaller places such as Cliffs End is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • The product specified
  • Any access equipment needed
  • How much there is to seal
  • The size and state of each joint

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Details that help us quote

A good diagnosis starts with the right details. Let us know:

  • When you need the work done
  • Whether the building will be occupied during the work
  • The product your specification calls for
  • The asbestos register, for older buildings

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or email us to discuss it first.

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Building owners and managing agents use us on everything from one building to a spread of sites around Cliffs End. Several sites can go on one quote, which keeps the paperwork simple.

Common problems we fix in Cliffs End

Product choice matters: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Neutral-cure, facade-grade products are what most external joints need.

Any of the following is a good reason to get the joints checked over:

  • Air leaks through failed facade joints
  • Staining on stone next to old sealant
  • Perimeter sealant that has split or peeled away
  • Water coming in around window frames

Recladding or extending a unit at a site like Old Timber Yard Industrial Estate, 1.1 miles to the north-east of Cliffs End, brings panel joints and frame perimeters into the programme.

Before you book anyone

  • Their plan for phasing and protecting the area
  • Will RAMS and insurance details be available?
  • Will failed sealant be removed rather than covered?
  • How joint depth will be controlled

How to choose a sealant contractor

What sealant work can’t fix

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Arranging specialist high-level access, which is planned with the client
  • Cracked or spalling substrates that need repair before sealing
  • Installing or repairing glazing systems

If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

Where we work in Cliffs End

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

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. For a building around Cliffs End, 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. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Getting the site ready

  • Tell us which areas need to stay in use
  • Let us know about inductions and permits
  • Make sure the joints can be reached

Aftercare for building managers

For the best life from the joints:

  • Walk the elevations once or twice a year
  • Avoid patch repairs on failed facade joints
  • Keep the sealant details on the building file
  • Share access with other external trades

Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly.

Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and cuts time on site.

Your questions answered

Is a smaller place like Cliffs End outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is a hospital such as Ramsgate General Hospital somewhere you can work?

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.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

Can you just add new sealant on top?

No. New sealant won’t hold on old sealant, so the old bead is cut away. That is what makes the new joint last.

Do you guarantee your work?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Will rain stop the work?

Rain and frost can pause external sealing. The programme allows for it and we tell you if the forecast changes things throughout the job.

Facades, frames and programmes in Cliffs End

With the shore within about 1 mile, Cliffs End counts as a coastal location. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. There are a number of hotels within about 2 miles of Cliffs End. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

Hotels like The Pegwell Bay Hotel (to the east of Cliffs End) rarely close for long, so refurbishment mastic is phased floor by floor. Projects at colleges like Nelson College London (2.7 miles north-east of Cliffs End) tend to run to term dates, so the mastic is planned tightly.
