Facade sealing near Padworth Common

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

Diagnose, treat, sign off

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. Smaller jobs around Padworth Common can be grouped with others nearby. A fixed quote is given before anything starts.

  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. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  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.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Share your working hours and any access restrictions
  • Flag any permit to work we will need

Request a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

How we handle facade sealing in Padworth Common

Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around, and we’ll fit the work around it. The enquiries we see most involve discoloured or dirty facade joints and facade joints cracked through the middle, across cladding panel joints, window and door perimeters and stone and brick facade joints. Most enquiries from Padworth Common start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In the countryside around places like Padworth Common, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.

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.

Common questions from Padworth Common clients

Is Padworth Common off your patch?

Not at all. Padworth Common is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Does your area include sites such as Stacey Industrial Park, near Padworth Common?

Yes. Estates, retail parks and business parks around Padworth Common, Stacey Industrial Park among them, are all within reach. Photos and a short description are enough for a first look.

Is it okay to overlay old mastic?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely. That is what makes the new joint last.

Do you replace windows or glass?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.

What hours do you work?

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

Which sealant do you use on facades?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others.

Is old mastic on our building likely to contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed; if it’s suspected, work stops until it has been tested. Removal of asbestos isn’t something we do.

Facade sealing in Padworth Common: the local picture

Padworth Common has a number of hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

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

When to bring in a specialist

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Cost factors for facade joints

To price the job, we consider:

  • The size and state of each joint
  • Travel to remote or island sites
  • Phasing around occupants
  • Whether old sealant has to be cut out first

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Details that help us quote

There’s no need for a formal survey. A few details are enough to get going:

  • The site address and postcode
  • Access details, including height
  • Any dates the work must fit around
  • Drawings or a marked-up plan, if available

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. For a chat about it beforehand, call the office on 01277 525 020 or email the details over.

When to call us in Padworth Common

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint.

Typical triggers for a call:

  • Old perimeter mastic that has dried out
  • Discoloured or dirty facade joints
  • Facade joints cracked through the middle
  • Gaps between rainscreen or cladding panels

For contractors refurbishing units at places like Stacey Industrial Park (1.7 miles south of Padworth Common), the mastic covers cladding panels, roller-door and window perimeters.

Questions to ask before you book

  • Is the sealant right for the movement and the substrate?
  • Their plan for phasing and protecting the area
  • What level of public liability insurance do they hold?
  • Whether their applicators hold CSCS cards

Questions to ask before you appoint anyone

Maintenance after handover

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

  • Note when each elevation was last resealed
  • Never let anyone seal over old sealant
  • Check the asbestos register before old mastic is disturbed
  • Walk the elevations once or twice a year

Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed rather than sitting against the joints.

Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Installing or repairing glazing systems
  • Movement beyond what any sealant can handle
  • Cracked or spalling substrates that need repair before sealing

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