Questions about Turnham Green

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

Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough

Can you work around term dates at a campus such as Richmond American University London?

Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS 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.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

What will the job cost?

Each job is quoted on its own details. To get one, phone 01277 525 020 or use the quote form with a description of the work.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Can you clear a mastic snag list before handover?

Yes. Send the snag list or photos and we’ll price it, with the work timed to your handover date.

Construction mastic in Turnham Green

External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work so it helps to sequence elevations with some flexibility. Internal sealing often fills those days. If you have sealant knocked or painted over by other trades and external joints sealed in damp or cold conditions that are now failing, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Turnham Green, preparation and product choice get the time they need.

Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Commercial clients in Turnham Green

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

What affects the price in Turnham Green

We price every job individually. The main factors are:

  • Whether old sealant has to be cut out first
  • Whether the work must be split into stages
  • Travel to remote or island sites
  • Access and working height

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.

Before you send an enquiry

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

  • The product your specification calls for
  • The type of building and who uses it
  • A wide shot and a close-up of the area
  • Rough lengths or quantities, or drawings if you have them

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Contractors’ notes for Turnham Green

As part of Greater London, Turnham Green is inside the ULEZ, which applies to every van on site. Delivery slots and scarce storage shape how and when the mastic goes in. A 2-mile radius around Turnham Green takes in plenty of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

For a contractor working at a hospital such as Barnes Hospital, 1.3 miles south of Turnham Green, perimeter and facade sealing is planned around patients and deliveries. Hotels like Chiswick Lodge Hotel, 0.6 miles to the north of Turnham Green, rarely close for long, so refurbishment mastic is phased floor by floor. Further education sites such as Ealing and West London College (2.8 miles north-west of Turnham Green) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Turnham Green is about 2 miles south of Acton, in Greater London. Businesses, contractors and managing agents in Turnham Green use us for work on mastic packages.

What sealant work can’t fix

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Faulty frames rather than failed sealant
  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
  • Oversized gaps that need packing or adjustment by others

If you are not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

What we seal

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

Diagnose, treat, sign off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes, and we clear our waste as we work. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  1. We price from the drawings, specification and programme you send.
  2. A fixed quote sets out the scope, the products and the sequence.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. Work follows the programme, area by area, as rooms and elevations become ready.
  5. Every joint is prepared, set to depth and sealed with the specified product.
  6. Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

Before we start on site

  • Tell staff and tenants when we’ll be in
  • Tell us which areas need to stay in use
  • Share your working hours and any access restrictions

Related advice

After the work

Keep the joints in good shape with a few simple steps:

  • Share drawings and the specification as soon as possible
  • Ask cleaners to use soft cloths around fresh sealant
  • Don’t force external sealing on a damp or frosty day
  • Don’t schedule sealing before decorators and flooring are done

A new structure shifts as it loses construction moisture. The right product in each joint copes with that, but caulk in a joint that moves more than expected may crack. We can advise if a joint needs a different product.

External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work, so we plan external work with that in mind.

Should maintenance staff do it?

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.
