Norbury: questions and answers

Can you cope with the access rules in a London building?

Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough

Will you plan work around the academic year at somewhere like King's College London?

Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is it okay to overlay old mastic?

No. New sealant won’t hold on old sealant, so the old bead is cut away and the faces are cleaned before resealing. That is what makes the new joint last.

Do you cover Norbury?

Yes. Sites across Norbury are covered, and the same phone number covers every area.

Should we check old sealant for asbestos?

It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register, and we will ask to see it. Suspect material is left alone until it has been tested.

How many days will you need on site?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

How long before the joints can be used?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

How we handle facade sealing in Norbury

Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. If you are dealing with facade joints cracked through the middle and previous reseals run over old sealant, we can help, whatever the surface. For commercial sealant work in Norbury, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Sites and facades in and around Norbury

Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Norbury. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. A 2-mile radius around Norbury takes in a good number of hotels. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.

Work at a hotel such as The Crystal Lodge Hotel (to the south of Norbury) tends to be programmed around bookings, mastic included. On a healthcare site such as British Home & Hospital for Incurables (1 mile north of Norbury), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Installing or repairing glazing systems
  • Specialist high-level access methods
  • Damaged frames that need replacing

If you are not sure, just call 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

Where we work in Norbury

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

Common problems we fix in Norbury

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained.

Clients normally get in touch after noticing one or more of the following:

  • New sealant peeling off old mastic
  • Hard, chalky sealant that no longer flexes
  • Damp patches beside frames after rain
  • Gaps between rainscreen or cladding panels

Projects at colleges like Spurgeon's College, 0.9 miles to the east of Norbury, tend to run to term dates, so the mastic is planned tightly.

What to look for in a quote

  • Whether primer will be used where the manufacturer specifies it
  • Their plan for phasing and protecting the area
  • Is the sealant right for the movement and the substrate?
  • What the guarantee covers, and for how long

How to choose a sealant contractor

How a job runs

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a job in Norbury, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Getting the site ready

  • Tell us which areas need to stay in use
  • Clear stock, furniture or equipment away from the joints
  • Let building users know which areas are affected

Advice

Work for main contractors and building owners

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Cost factors for facade joints

These are the things that shape the price:

  • Whether the work must be split into stages
  • Removal of failed or old sealant
  • The site’s rules and procedures
  • Specialist products, such as fire-rated or hygienic sealants

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

What to include in your enquiry

A few photos plus some basic facts will normally do. It helps to include:

  • Clear photographs of the problem areas
  • What the building is and how it’s used
  • Any specification or named product
  • How the joints are reached, and at what height

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