About our mastic sealing in Angell Town

For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Resealed mastic joints in Angell Town carry our 12-month guarantee. If you’re dealing with old repairs sealed over failed mastic and occupiers reporting cold air round windows, we can put it right. Facilities teams, main contractors and managing agents in Angell Town tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Across Greater London, Angell Town included, the ULEZ applies, and parking and loading rules differ from street to street. For a block or estate, it helps to know where we can park and stage materials.

A 12-month guarantee applies to all our work. Should something we installed fail, speak to us on 01277 525 020 or send details through our quote form and we’ll come back to it.

Quoting for work in Angell Town

Quotes vary with the job. Expect it to depend on:

  • Backing rod, priming and other preparation
  • Site requirements such as inductions and permits
  • Which sealant the job calls for
  • Whether old sealant has to be cut out first

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Details that help us quote

A few photos plus some basic facts will normally do. Please tell us:

  • Photos of the joints, close up and from further back
  • Specification clauses that apply
  • Approximate linear metres or a joint schedule
  • What the building is and how it’s used

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call the office on 01277 525 020 or use the quote form.

Questions about Angell Town

Do you work in London buildings with loading restrictions?

Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry.

Can you quote for a block close to Loughborough Junction station?

Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.

What about access for upper-floor joints?

Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we will tell you how we’d approach it.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Can you plan resealing across several buildings?

Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

Do you work for managing agents and housing associations?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.

Different surfaces, different methods

Planned maintenance

How long mastic lasts depends on exposure, movement and the product used. Regular inspection is the best way to plan resealing.

Estate-wide resealing programmes

Using the same products throughout keeps the estate consistent and easier to manage.

Leave it or put it right?

Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Failed sealant in a building in Angell Town can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Why us?

  • One phone line for London, the South East and Scotland
  • A Constructionline member, so easy to vet
  • Coloured sealants to suit the setting, where available
  • Work to your specification and the manufacturer’s guidance

Site staff or a sealant specialist?

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Make sure the joints can be reached
  • Confirm the product named in the specification

Advice

Honest limits

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Frames that are rotten, warped or broken
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)

If in doubt, phone 01277 525 020 or email a schedule or drawings and we’ll say what we think.
