Construction mastic for Tolworth sites

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

Tolworth: questions and answers

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

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Could you schedule work at a campus like Kingston University for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

How do you work with the site programme?

We work to your programme. Tell us the sequence and we will plan applicators around it.

Do you work in Tolworth?

Yes. Sites across Tolworth are covered.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Construction mastic in Tolworth

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 we plan elevations with the forecast and the programme in mind. Internal areas can normally carry on while the outside waits. Site teams most often ask us about old sealant on a refurbishment that needs stripping before new work and frame perimeters left unsealed or poorly sealed, across cladding and panel joints, window and door perimeters and floor and skirting junctions. For commercial sealant work in Tolworth, you deal with one contact from quote to sign-off, whether it’s one building or several.

Every London site, Tolworth included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Alongside that, sites usually need booked deliveries and a plan for where materials go.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Work for main contractors and building owners

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. Drawings, specification and programme come to us.
  2. Quantities are measured and a fixed price returned.
  3. The sequence is agreed with the site manager.
  4. Each area is sealed when it’s released.
  5. Every joint is cleaned, set to depth and sealed with the specified product.
  6. Snags are cleared and the package signed off with our 12-month guarantee.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Let us know about inductions and permits
  • Share the asbestos register for older buildings

Quotes

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or send photos by email.

What we can’t put right

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Glazing units that are cracked or misted
  • Damage to finishes by other trades after we’ve sealed
  • Frame gaps too wide for sealant, which the installer needs to correct

If you are not sure, just give us a call on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

Where we work in Tolworth

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

Cost factors for mastic packages

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • The site’s rules and procedures
  • Phasing around occupants
  • How much there is to seal
  • Travel to remote or island sites

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What we need to price the job

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

  • The product your specification calls for
  • The postcode of the building
  • Photos of the joints, close up and from further back
  • The type of building and who uses it

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Facades, frames and programmes in Tolworth

Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Tolworth. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. Tolworth has a number of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

When units on a site such as Fairfield Trade Park (to the north of Tolworth) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. For contractors at a college like Hillcroft College, 1 mile to the north-west of Tolworth, perimeters and internal sealant are timed for the holidays. Work at a hotel such as Bosco Hotel & Lounge (to the north-west of Tolworth) tends to be programmed around bookings, mastic included.

Tolworth is about 2 miles north-west of Ewell, in Greater London. Tolworth sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Across Greater London, 764 places are covered, Tolworth among them. Our London page has more on work in that area.

Work on mastic packages is covered throughout KT5, KT6 and KT3, whatever the building. For a building on Pyne Road, Ewell Road and Derby Road or nearby, we can quote for mastic packages. We also cover Berrylands (1 mile north), Old Malden (1 mile south-east), Surbiton (1 mile north-west), Worcester Park (1 mile south-east) and Chessington (2 miles south-west) for mastic packages. Further afield, our area takes in London (11 miles north-east), City of Westminster (11 miles north-east), Marylebone (11 miles north-east), Kensington (9 miles north-east), St Pancras (12 miles north-east) and Shoreditch (13 miles north-east).

Looking after the joints

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

  • Note which sealant went where at handover
  • Release areas for mastic once other trades have finished in them
  • Flag uneven or tapered frame gaps early
  • Get the mastic subcontractor involved early in the programme

If a joint is damaged after sealing, flag it early. Snags can be picked up in a planned close-out visit.

Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out.

Different surfaces, different methods

Bathrooms, en suites and washrooms

On multi-unit schemes, consistency matters across hundreds of bathrooms. One applicator team gives the same finish everywhere following the programme.

External facade and movement joints

Movement joints in the facade are sealed with a product suited to the expected movement. Depth is controlled with backing rod so the bead bonds to two sides only.
