Facade sealing near Penenden Heath

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Aftercare for building managers

Regular inspection catches problems early. In particular:

  • Walk the elevations once or twice a year
  • Ask about asbestos in pre-2000 mastic
  • Avoid patch repairs on failed facade joints
  • Investigate damp beside windows promptly

Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade.

Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail, rather than waiting for a ceiling stain.

How we handle facade sealing in Penenden Heath

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. If you are dealing with failed sealant on precast panel joints and air leaks through failed facade joints, we can put it right, whatever the surface. Whoever orders the work in Penenden Heath, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Conversions around smaller places like Penenden Heath often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the quote is worked out

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Whether old sealant has to be cut out first
  • Phasing around occupants
  • Site requirements such as inductions and permits
  • How accessible the joints are

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Details that help us quote

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

  • Anything awkward about access or site hours
  • The type of building and who uses it
  • The site address and postcode
  • Photos of the joints, close up and from further back

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Your questions answered

Is Penenden Heath too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Will you plan work around the academic year at somewhere like University for the Creative Arts?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you handle several sites?

Yes. A group of buildings can go on one quote, with one point of contact.

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.

Can you work in cold or wet weather?

Rain and frost can pause external sealing. We plan for weather and keep you updated throughout the job.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Is your workmanship covered by a guarantee?

Yes. Workmanship is guaranteed for 12 months on every job.

When to bring in a specialist

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.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

What we can’t put right

We check first that sealant really is the fix. It isn’t the answer for:

  • Water getting in through cracked render or porous masonry
  • Movement beyond what any sealant can handle
  • Specialist high-level access methods

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we will say what we think before you book.

Surfaces we seal

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

For managing agents and facilities managers

We work for building owners and managing agents on everything from one building to a spread of sites around Penenden Heath. One quote can cover more than one site, which keeps the paperwork simple.

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a site in Penenden Heath, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Send any specification or drawings in advance
  • Let building users know which areas are affected
  • Make sure the joints can be reached

Getting a fixed quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or use the quote form with what you know.
