Facade sealing across Lidsing

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

How the quote is worked out

To price the job, we consider:

  • How much existing material needs removing
  • The total length or number of joints
  • Working within restricted access windows
  • Site requirements such as inductions and permits

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Details that help us quote

The more we know, the firmer the quote. Helpful details to send:

  • Where the site is, with the postcode
  • Whether the building will be occupied during the work
  • Asbestos survey details if the building is older
  • Drawings or a marked-up plan, if available

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or email drawings and photos if you’d rather talk the job through.

How we handle facade sealing in Lidsing

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure for clients around Lidsing. Coping and flashing joints are included where sealant is the specified fix. We work on window and door perimeters, stone and brick facade joints and cladding panel joints, and what we’re called in for most is air leaks through failed facade joints and old perimeter mastic that has dried out. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Lidsing, preparation and product choice get the time they need.

In the countryside around places like Lidsing, 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 usually what’s needed.

A 12-month guarantee applies to all our work in Kent. Should something we installed fail, give us a call on 01277 525 020 or email drawings and photos and we’ll come back to it.

General trades versus a specialist

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Mastic packages on Lidsing sites

Central London is about 31 miles from Lidsing. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand. Lidsing is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.

With historic properties like Restoration House, 4.7 miles north-west of Lidsing, in the area, refurbishment work often meets old masonry that needs compatible sealants. Building work at universities like University for the Creative Arts - Rochester, 4 miles north-west of Lidsing, is often timed for the summer, mastic included.

Lidsing is about 2 miles south-east of Chatham, in Kent. Businesses, contractors and managing agents in Lidsing use us for work on facade joints, as part of our coverage of Kent. Lidsing is one of 931 places we cover in Kent for facade joints. Our London page has more on work in that area.

Business premises anywhere in ME7 are within our area for facade joints. Just outside Lidsing, we also work in Dunn Street (1 mile south-east), Bredhurst (1 mile east), Lordswood (1 mile north-west), Kemsley Street (1 mile east) and Scragged Oak (1 mile south-east). Bigger towns within reach include Maidstone (5 miles south), Sittingbourne (7 miles east), Gravesend (11 miles north-west), Tonbridge (15 miles south-west), Faversham (14 miles east) and Northfleet (12 miles north-west).

What’s near Lidsing

Surface by 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, and we will mention any edges that need repair.

Coping and flashing joints

Sometimes the coping or flashing itself has failed. We tell you if the fix is a roofing or metalwork job rather than a reseal.

Signs you need facade sealing in Lidsing

Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back.

These are often picked up first by site or facilities staff:

  • Air leaks through failed facade joints
  • Unsightly perimeter sealant on a visible elevation
  • Failed seals around shopfront and entrance frames
  • Facade joints cracked through the middle

For contractors refurbishing units at places like Lordswood Industrial Estate (0.8 miles west of Lidsing), the mastic covers cladding panels, roller-door and window perimeters.

What to look for in a quote

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • What the guarantee covers, and for how long
  • How the joint faces will be prepared and primed
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

Questions we’re asked in Lidsing

Can you work on a hospital site such as Spire Alexandra Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Lidsing too small for you to travel to?

No. Places such as Lidsing are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

What will the job cost?

Each job is quoted on its own details. To get one, speak to us on 01277 525 020 or use the quote form with a description of the work.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Can the sealant be colour-matched?

It depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

Diagnose, treat, sign off

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. For a building around Lidsing, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  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 both faces cleaned back.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

What we need from you

  • Tell us your opening times and when work is allowed
  • Flag any permit to work we will need
  • Agree which areas must stay open

Request a quote

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

Advice

When it isn’t the sealant

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

  • Joints whose design needs changing by the specifier
  • Damaged frames that need replacing
  • Arranging specialist high-level access, which is planned with the client

If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

What we seal

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