About our construction mastic in Yeading

A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility. If you have existing joints on a refurb that need cutting out and resealing and a mastic package split between trades with no clear owner, we can help. A specialist sealant contractor works differently from a general builder: in Yeading, that means joint design, primers and backing rod as standard.

Every London site, Yeading included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.

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.

Different surfaces, different methods

External facade and movement joints

Many facade substrates need a primer before sealing. We prime where the manufacturer specifies.

Window and door perimeters

Internal perimeters are normally sealed with a paintable product where decorating follows. The specification decides which with colours matched to the frame where needed.

How a job runs

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. All of Greater London is in the ULEZ, and kerbside space in Yeading can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We price from the drawings, specification and programme you send.
  2. We return a fixed quote that ties the mastic package to your programme.
  3. You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
  4. We seal each plot or floor as it’s released to us.
  5. Every joint is prepared, set to depth and sealed with the specified product.
  6. We close out snagging and hand over with a 12-month guarantee.

Before we start on site

  • Tell us which areas need to stay in use
  • Tell us what induction or permit system the site runs
  • Tell us your opening times and when work is allowed

Getting a fixed quote

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

What we can’t put right

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

  • Damage to finishes by other trades after we’ve sealed
  • Glazing units that are cracked or misted
  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)

Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Where we work in Yeading

  • Brick and block movement joints
  • Internal decorators’ caulk
  • Cladding and panel joints
  • Floor and skirting junctions
  • Sanitary and kitchen joints
  • Window and door perimeters

Your questions answered

Can you take on a job at a hospital such as Ealing Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Can work at a site such as Brunel University of London fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can the building stay open while you work?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

What accreditations do you hold?

Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. We confirm any paperwork you need with the quote.

What does a mastic package usually include?

Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens, all priced as one package.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

After the work

To get the most from the new sealant:

  • Release areas for mastic once other trades have finished in them
  • Keep finished joints away from paint, plaster and scrapers
  • Ask installers to correct oversized gaps first
  • Stick to the specified sealant rather than a generic substitute

Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby; we confirm the time for each product.

Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out, and avoids a rush.

Cost factors for mastic packages

Your fixed quote is built from the real scope. It allows for:

  • The total length or number of joints
  • Joint width, depth and condition
  • How accessible the joints are
  • Removal of failed or old sealant

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Sending details for a quote

Good information means a firmer quote. Helpful details to send:

  • A wide shot and a close-up of the area
  • The asbestos register, for older buildings
  • Drawings or a marked-up plan, if available
  • The product your specification calls for

Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, phone 01277 525 020 or email a schedule or drawings.

When to bring in a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Mastic packages on Yeading sites

As part of Greater London, Yeading is inside the ULEZ, which applies to every van on site. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. A 2-mile radius around Yeading takes in several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

School extensions, at buildings such as Brookside Primary School, typically run to the summer holidays, mastic included. On a campus such as Brunel University of London, 3.5 miles to the west of Yeading, new teaching buildings and residences are normally built and refurbished around the academic year. On a healthcare site such as Ealing Hospital, 2.5 miles south-east of Yeading, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Yeading is about 2 miles north-east of Hayes, in Greater London. We cover commercial sites throughout Yeading, for single jobs and planned programmes alike. Yeading is one of 764 places we cover in Greater London. We also cover London, around 13 miles from Yeading.

We cover the UB5, UB4 and UB1 postcode districts. Among the streets we cover are Owen Road, Friar Road and Maple Road. If your building is just outside Yeading, we cover Yiewsley (1 mile north), Dormers Wells (2 miles south-east), Northolt (2 miles north-east), Southall (2 miles south) and South Ruislip (2 miles north). A short drive away, we cover London (13 miles east), City of Westminster (10 miles east), Marylebone (11 miles east), Kensington (8 miles east), St Pancras (12 miles east) and Shoreditch (13 miles east).
