Mastic sealing for commercial buildings in West Wickham

On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Entrances and stairwells are kept in use while we work. If you have draught complaints from residents or tenants and window mastic that has split and shrunk, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in West Wickham is the same: the right product in a properly prepared joint.

London’s ULEZ covers every borough, and parking and loading rules vary street by street. For a block or estate, it helps to know where we can park and stage materials.

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.

On site: what to expect

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. Planning a London job such as one in West Wickham starts with access: 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. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. Joints are resealed and tooled.
  6. Each building is checked and signed off with the 12-month guarantee.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Move anything stored against the joints
  • Explain the parking and delivery arrangements

Keeping the joints sound

After handover, a little attention goes a long way:

  • Mention RAMS, insurance or CSCS requirements up front
  • Avoid piecemeal callouts where you can
  • Ask residents or tenants to report leaks and draughts early
  • Log resealing dates block by block

Log the date and extent of the resealing for each block. It helps plan the next round and shows what was done.

The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.

Leave it or put it right?

Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. Failed sealant in a building in West Wickham can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.

Pricing mastic joints depends on quantities, condition and access. Ask us for a fixed quote.

Doing it in-house

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

How the quote is worked out

We price every job individually. The things that drive the figure:

  • Which sealant the job calls for
  • Removal of failed or old sealant
  • Quantities, in metres or numbers
  • The size and state of each joint

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Before you send an enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • How the joints are reached, and at what height
  • Whether an asbestos survey exists
  • Approximate linear metres or a joint schedule
  • The type of building and who uses it

For a fixed quote, call 01277 525 020 or email us with the site address and an outline of the work. Our quote form is another easy route.

Looking after buildings in and around West Wickham

West Wickham has five care or nursing homes no more than 2 miles away. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings. London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We work to your notice and access plan.

Property owners at sites such as Chaffinch Business Park, 1.8 miles north-west of West Wickham, can have mastic renewed between lettings. Older buildings near West Wickham, from historic houses such as Addington Palace (to the south-west of West Wickham) to more modest stock, need compatible products when frames are resealed. Older community buildings, St Francis of Assisi among them, often have frames of mixed ages whose mastic varies.

Questions we’re asked in West Wickham

Can work in a care setting near West Wickham go ahead while residents are there?

Yes. We work around residents’ routines, a room or two at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

Do you take on jobs in West Wickham where loading and access are tightly controlled?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Share the building’s contractor rules and we’ll work to them. The ULEZ covers the whole of Greater London, which we allow for

What will the job cost?

There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.

Can you seal joints high up on a block?

We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned, and we will tell you how we’d approach it.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.

Will you come and look before quoting?

That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

Is mastic sealing guaranteed?

A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
