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

Mastic sealing in Bellfields

On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Entrances and stairwells are kept in use while we work. If you have damaged joints in communal entrances and corridors and damp patches beside frames, we can put it right. Whoever orders the work in Bellfields, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For landlords and associations with stock in and around Bellfields, grouping buildings into one visit saves travel. Send the addresses and photographs and we’ll quote for all of them together.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Our process

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Work in places the size of Bellfields is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. Dates and areas are agreed so occupiers can be told.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

Preparing the site

  • Warn occupants and staff about the work
  • Share your working hours and any access restrictions
  • Send any specification or drawings in advance

Quotes

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Advice

Different surfaces, different methods

Planned maintenance

Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.

Communal areas

We keep entrances and stairs open throughout. Work is planned in sections.

Quoting for work in Bellfields

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

  • The product specified
  • Backing rod, priming and other preparation
  • The site’s rules and procedures
  • Removal of failed or old sealant

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

Before you send an enquiry

Whether it’s one area or a whole building, the same details help:

  • Whether an asbestos survey exists
  • What the building is and how it’s used
  • Drawings or a marked-up plan, if available
  • Where the site is, with the postcode

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or email drawings and photos.

What sealant work can’t fix

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Water coming in from the roof or rainwater goods
  • Substrate edges that need repairing first
  • Frames that are rotten, warped or broken

Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly before you book.

Where we work in Bellfields

  • External wall and movement joints
  • Communal entrances and stairwells
  • Window and door perimeters on blocks
  • Balcony and threshold joints
  • Communal kitchens and washrooms
  • Shopfronts below residential blocks

General trades versus a specialist

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Planned mastic for Bellfields portfolios

Bellfields is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Bellfields lies roughly 27 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations.

For a school such as Pond Meadow School, perimeter mastic on windows and doors is a holiday job. Property owners at sites such as Ladymead Retail Park (to the south of Bellfields) can have mastic renewed between lettings.

Questions we’re asked in Bellfields

Is a smaller place like Bellfields outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Do you cover business parks and estates near Bellfields, such as Ladymead Retail Park?

Yes, sites like Ladymead Retail Park are within our area, along with the rest of Bellfields. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Do you work with property factors and landlords?

Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.

Can you quote from photographs?

It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.

Signs you need mastic sealing in Bellfields

Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.

Site and facilities staff are often the first to spot these:

  • Patchy repairs in mismatched sealant
  • No planned programme for sealant
  • Failed external movement joints
  • Draught complaints from residents or tenants

Trustees of buildings like St Peter's Church can bring frame and external mastic into a planned maintenance list.

Questions to ask before you book

  • Do they follow the manufacturer’s priming guidance?
  • Which product they’ll use, and why it suits the joint
  • What level of public liability insurance do they hold?
  • The terms of the workmanship guarantee
