Mastic sealing for Ickenham sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Looking after the joints

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Include mastic in your cyclical inspections
  • Group repairs into a planned programme
  • Make it easy for occupiers to report draughts
  • Prioritise elevations facing the weather

Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.

Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.

How we handle mastic sealing in Ickenham

Across Ickenham and the rest of Greater London, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote or we can visit. We work on shopfronts below residential blocks, balcony and threshold joints and communal entrances and stairwells, and the failures we’re asked to look at most are cracked, hardened mastic round windows on a block and damaged joints in communal entrances and corridors. For commercial sealant work in Ickenham, you deal with one contact from quote to sign-off, whether it’s one building or several.

For managing agents in Ickenham, resident access, notice periods and the building’s rules shape the job. Work is planned with the agent so residents get notice and access is arranged in advance.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Commercial clients in Ickenham

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Ickenham can sit alongside others in a wider programme.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Do you need mastic sealing in Ickenham?

Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.

What tends to prompt an enquiry:

  • Leaks at window and door perimeters
  • Movement joints with sealant missing
  • No planned programme for sealant
  • Draught complaints from residents or tenants

Property owners at sites such as Uxbridge Business Park (to the west of Ickenham) can have mastic renewed between lettings.

What your quote should include

  • Will RAMS and insurance details be available?
  • What level of public liability insurance do they hold?
  • Will CSCS-carded applicators be on site?
  • Whether primer will be used where the manufacturer specifies it

How to choose a sealant contractor

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. All of Greater London is in the ULEZ, and kerbside space in Ickenham can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. A building-by-building inspection lists the failed joints.
  2. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  4. Old mastic is removed and the joint faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. Each building is checked and signed off with the 12-month guarantee.

Getting the site ready

  • Let building users know which areas are affected
  • Have the specification and drawings to hand
  • Clear stock, furniture or equipment away from the joints

Request a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or send details through our quote form.

Your questions answered

Will you take on work at estates like Uxbridge Business Park, close to Ickenham?

Yes. Our area takes in Ickenham and its surroundings, with estates and business parks such as Uxbridge Business Park included. Photos and a short description are enough for a first look.

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

Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day.

Can you plan resealing across several buildings?

Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.

How do you handle work on occupied blocks?

Occupiers stay in the building throughout. If any flats or units need access, we’ll tell you in advance so you can arrange it with occupiers.

How much does the work cost?

We don’t publish prices, as every site differs. With photos or drawings, we can give you a fixed quote.

What guarantee do you give on resealing?

Our workmanship carries a 12-month guarantee, backed by public liability insurance.

Planned mastic for Ickenham portfolios

Blocks in London are usually run by managing agents, landlords or housing associations, with residents to notify and access to arrange. We fit the programme to your notice periods.

Churches, halls and community buildings such as St Giles' Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Site managers at schools like The Douay Martyrs Catholic School can fit frame mastic into the summer works.

When something else is needed

Honesty saves time and money. New sealant won’t cure:

  • Failed window or door frames, which need a window contractor
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Asbestos-containing sealant, which we don’t remove

If in doubt, call the office on 01277 525 020 or email us and we will say what we think before you book.
