Facade sealing in Luddesdown

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Why act early in Luddesdown

Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. Halls, stores and units around places like Luddesdown may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Why us?

  • Fully insured, including public liability cover
  • Coloured sealants to suit the setting, where available
  • Commercial sealant work since 2005
  • Products installed to the manufacturer’s instructions

How we handle facade sealing in Luddesdown

Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. The enquiries we see most involve weathered facade joints that have lost their grip and cladding panel joints that have opened up, across stone and brick facade joints, cladding panel joints and perimeter joints where frames meet the structure. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Luddesdown is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Construction in and around smaller places such as Luddesdown is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Quoting for work in Luddesdown

Each job is priced on its own details. The main factors are:

  • Distance, for remote addresses
  • The product specified
  • The size and state of each joint
  • The site’s rules and procedures

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Sending details for a quote

To price the job accurately, we need to understand the site. Useful things to include:

  • What the building is and how it’s used
  • Drawings or a marked-up plan, if available
  • Where the site is, with the postcode
  • When you need the work done

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 drawings and photos to discuss it first.

Our process

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. If others near Luddesdown need work, visits can be combined. A fixed quote is given before anything starts.

  1. We start with photos, 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 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.

Before we start on site

  • Make sure the joints can be reached
  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings

Request a quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Related advice

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

What the job involves on each surface

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building, so preparation and product choice matter.

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported before sealing.

Questions we are asked in Luddesdown

Can you work on a hospital site such as French Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is a smaller place like Luddesdown outside your area?

Not at all. Luddesdown is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Do you replace failed glazing units?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, such as perimeter joints where frames meet the structure.

Are you insured?

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

Do you run new sealant over the existing bead?

No. New sealant won’t hold on old sealant, so the old bead is cut away. Nothing else gives a bond that lasts.

Honest limits

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Joints whose design needs changing by the specifier
  • Damp caused by condensation inside the building
  • Cracked or spalling substrates that need repair before sealing

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think.

What we seal

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

Facades, frames and programmes in Luddesdown

At about 23 miles from central London, Luddesdown is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.

On a healthcare site such as French Hospital, 4.7 miles east of Luddesdown, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. When units on a site such as Bowes Industrial Centre (to the west of Luddesdown) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. With historic properties like Cobham College (to the north of Luddesdown) in the area, refurbishment work often meets old masonry that needs compatible sealants.
