Facade sealing in Honor Oak

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

Looking after the joints

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Confirm the survey covers external sealants in older buildings
  • Clear debris that holds water against joints
  • Avoid patch repairs on failed facade joints
  • Inspect facade joints on a regular cycle

Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Facade sealing in Honor Oak

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on commercial buildings in Honor Oak. Coping and flashing joints are included where sealant is the specified fix. We work on stone and brick facade joints, shopfront frames and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are failed seals around shopfront and entrance frames and cladding panel joints that have opened up. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Honor Oak is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Every London site, Honor Oak included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

When something else is needed

Being straight saves everyone time. Fresh joints won’t solve:

  • Specialist high-level access methods
  • Joints too narrow for the movement they take, which need redesign
  • Damaged frames that need replacing

Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Facade sealing around Honor Oak: points for this area

Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Honor Oak. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. Honor Oak has several hotels close by, all within 2 miles. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.

Units on estates such as Clyde Vale Industrial Estate (1 mile south of Honor Oak) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Projects at colleges like Christ the King: Aquinas Sixth Form College, 1.3 miles north of Honor Oak, tend to run to term dates, so the mastic is planned tightly. Extensions at sites like University Hospital Lewisham, 1.5 miles east of Honor Oak, normally sit beside working departments, and the mastic follows strict access rules.

Honor Oak is about 2 miles south-west of New Cross, in Greater London. Any commercial site in Honor Oak is covered. We work across 764 places in Greater London.

When to bring in a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

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

On site: what to expect

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. All of Greater London is in the ULEZ, and kerbside space in Honor Oak can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full.
  4. Primer is applied where the maker specifies 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

  • Clear stock, furniture or equipment away from the joints
  • Have the specification and drawings to hand
  • Point out any areas we must not close

How the job changes by surface

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, as the specification sets out.

Render and coated surfaces

Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.
