Our process

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. Jobs in and around smaller places like Forty Green are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First we agree which sealant type the joint needs.
  2. We compare the target colour with the colours available.
  3. You approve the colour, on site if it’s critical.
  4. The existing bead comes out, then faces are cleaned and backed.
  5. Edges are masked and the coloured sealant applied and tooled.
  6. Masking comes off and the work is checked with you.

What we need from you

  • Let us know about inductions and permits
  • Clear stock, furniture or equipment away from the joints
  • Point out parking and an unloading spot

Coloured sealant in Forty Green

Shop fits, hotels and offices are where colour-matched sealant earns its place. A mismatched bead can make good joinery look unfinished. The aim is a colour from the product’s range that disappears into the surface. We work on hotel bathrooms and public areas, powder-coated and anodised frames and office fit-out finishes, and the usual reasons a site gets in touch are patch repairs in several different colours and white or grey sealant that clashes with the finish. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Forty Green is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Business units in the countryside around places like Forty Green are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

What we are called out for in Forty Green

A coloured joint can fail like any other: it can crack, peel or harden with age and movement. The fix is a full cut-out and a new bead in the right colour.

Things that usually lead to an enquiry:

  • Old sealant that has yellowed, darkened or faded
  • Stained or mouldy coloured joints in washrooms
  • Poorly tooled joints on visible finishes
  • Patch repairs in several different colours

If you run a unit on an estate such as Bandet Way Industrial Estate (3 miles west of Forty Green), the trade counter, offices and staff facilities have joints to look after as well as the warehouse.

Before you book anyone

  • What the guarantee covers, and for how long
  • Whether primer will be used where the manufacturer specifies it
  • Their public liability cover
  • The named product and why it was chosen

How to choose a sealant contractor

Looking after the joints

To get the most from the new sealant:

  • Record the product and colour reference on the building file
  • Keep harsh solvents away from visible joints
  • Insist on the agreed colour for any repair
  • Agree the sealant colour early and write it into the specification

Expect some change in appearance over the years. That is normal for exposed sealant.

Ask for a trial bead on high-profile areas. Seeing the cured colour in place avoids surprises.

Questions about Forty Green

Can you work at a site such as Bandet Way Industrial Estate, by Forty Green?

Yes, sites like Bandet Way Industrial Estate are within our area, along with the rest of Forty Green. To start, just speak to us on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Is a smaller place like Forty Green outside your area?

No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Can we specify the colour by RAL number?

Yes. Give us the RAL reference and we’ll check it against the product’s range. We’ll tell you which colour is closest before work starts.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

Why act early in Forty Green

Standard white or grey sealant is cheaper to stock, but it doesn’t always suit the finish. On visible work, the small extra effort of a colour from the product’s range pays off in how the finished space looks. For buildings around smaller places like Forty Green, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why choose Mastic Doctor in Forty Green

Cost factors for colour-matched joints

The price varies from site to site. It mainly depends on:

  • Site requirements such as inductions and permits
  • The product specified
  • Quantities, in metres or numbers
  • Access and working height

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Sending details for a quote

However big the job, these details speed things up:

  • Specification clauses that apply
  • Asbestos survey details if the building is older
  • A wide shot and a close-up of the area
  • Drawings or a marked-up plan, if available

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
