Mastic sealing near Yeading

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Misted or failed double-glazed units
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Failed window or door frames, which need a window contractor

If you are not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer.

What we seal

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

How we handle mastic sealing in Yeading

On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Entrances and stairwells are kept in use while we work. The enquiries we see most involve estate-wide sealant that is simply worn out and open joints in brickwork or panels, on window and door perimeters on blocks, balcony and threshold joints and communal kitchens and washrooms. For commercial sealant work in Yeading, you deal with one contact from quote to sign-off, whether it’s one building or several.

Across Greater London, Yeading 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.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, 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.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

What happens if it’s left?

Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Failed sealant in a building in Yeading can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why clients in Yeading choose us

  • CSCS-carded applicators
  • RAL and finish matching where the product range allows
  • Standard and matched colours in many product ranges
  • Fully insured, including public liability cover

For managing agents and facilities managers

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Looking after the joints

Cleaning and maintenance staff play a part too. Pass these on to them:

  • List the paperwork your organisation requires when you send details
  • Check sealant joints during planned building inspections
  • Start inspections with the most exposed faces
  • Encourage occupiers to report problems at frames

Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.

Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.

How a job runs

Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. For a job in Yeading, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the 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.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Arrange parking or a loading space
  • Send your site hours and access windows

FAQs: Yeading

Do you work for managing agents with blocks near Southall station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.

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

Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. The ULEZ covers the whole of Greater London, which we allow for

Can you take on resealing for a block portfolio?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.

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’ll tell you how we’d approach it.

How do you handle work on occupied blocks?

Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so it can be arranged.

Can you reseal a whole block or estate?

Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.

Do you guarantee the mastic work?

A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
