Construction mastic across Baker's Cross

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

Our process

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before we move to the next. If others near Baker's Cross need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We walk the site or review drawings to understand the package.
  2. A fixed quote sets out scope, products and phasing.
  3. Paperwork is agreed and applicators are inducted on site.
  4. We seal plot by plot or floor by floor in line with the programme.
  5. Problems we find, such as oversized gaps, are raised right away.
  6. Final snagging is completed and the 12-month guarantee applies.

Preparing the site

  • Point out parking and an unloading spot
  • Have the specification and drawings to hand
  • Send asbestos survey details if the building is pre-2000

If you’re dealing with bath and shower joints scraped during the final clean and a long mastic snag list close to completion, we can put it right, whatever the surface.

Is Baker's Cross too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Do you guarantee new-build sealant work?

Each package is backed by a 12-month guarantee. We are also fully insured for public liability.

Is colour matching possible?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

Are you insured?

Yes. We are fully insured, including public liability cover.

What will the job cost?

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

New build and refits around Baker's Cross

Rainfall across the South East, Baker's Cross included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager. A number of hotels sit less than 2 miles from Baker's Cross. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

Extensions at sites like Benenden Hospital, 3.3 miles to the east of Baker's Cross, typically sit beside working departments, and the mastic follows strict access rules. For contractors refurbishing units at places like Hartley Dyke Business Centre (1.4 miles south-west of Baker's Cross), the mastic covers cladding panels, roller-door and window perimeters. Hotels like The George Hotel (under half a mile north-west of Baker's Cross) rarely close for long, so refurbishment mastic is phased floor by floor.

How the quote is worked out

Your fixed quote is built from the real scope. It takes account of:

  • The size and state of each joint
  • Location, for remote and island sites
  • The site’s rules and procedures
  • Specialist products, such as fire-rated or hygienic sealants

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

What we need to price the job

However big the job, the same details help:

  • Photos of the joints, close up and from further back
  • When you need the work done
  • Specification clauses that apply
  • Where the site is, with the postcode

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

What happens if it’s left?

Sealing over damaged or contaminated new joints might save a day, but it rarely lasts. Sealant can’t grip a contaminated or existing bead, and the defect comes back after handover. We cut out and redo the joint properly. Halls, stores and units around places like Baker's Cross may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

How the job changes by surface

Bathrooms, en suites and washrooms

In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line.

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.

After the work

To get the most from the new sealant:

  • Don’t force external sealing on a damp or frosty day
  • Flag uneven or tapered frame gaps early
  • Keep finished joints away from paint, plaster and scrapers
  • Don’t schedule sealing before decorators and flooring are done

Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.

Sealing outside when the joint is damp or too cold leads to poor adhesion. Holding off until conditions suit avoids callbacks.
