How a job runs

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a building around Colthrop, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We confirm the joint type and the product it needs.
  2. Your RAL reference, sample or photo is checked against that product’s colours.
  3. You approve the colour, on site if it’s critical.
  4. We cut out the existing bead, clean and set the depth.
  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

  • For older buildings, check the asbestos register before work
  • Clear stock, furniture or equipment away from the joints
  • Arrange parking or a loading space

Coloured sealant in Colthrop

Coloured sealant work ranges from a new shop fit to replacing failed joints on an existing building on sites in Colthrop. When replacing old joints, the new colour typically has to match what’s already there. If you have old sealant that has yellowed, darkened or faded and marked sealant in hotel bathrooms, we can put it right, whatever the surface. Whoever orders the work in Colthrop, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Rural business units near smaller places such as Colthrop are frequently converted agricultural buildings. 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.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

What happens if it’s left?

Matching new joints to the existing ones is easier when the whole run is done together. Small repairs at different times rarely match. Around Colthrop, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we’ll quote for the lot.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Why us?

  • Colours chosen to suit frames, cladding or finishes where possible
  • Workmanship guaranteed for 12 months
  • Constructionline member for supplier checks
  • CHAS accredited contractor

Do you need coloured sealant in Colthrop?

Failed sealant still has to be dealt with, whatever its colour: 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.

Look out for the following:

  • Hotel refurbishments with a set colour scheme
  • Sealant that no longer suits recoated frames
  • Old sealant that has yellowed, darkened or faded
  • A run of joints in mismatched shades

Occupiers with premises at both Pipers Lane Industrial Estate and Thatcham Business Village could have the sealant at each handled under one quote.

What your quote should include

  • How joint depth will be controlled
  • How they handle RAMS and site documents
  • The terms of the workmanship guarantee
  • Who will actually carry out the work

FAQs: Colthrop

Is Colthrop too small for you to travel to?

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

Can the sealant on our Colthrop premises match the finishes?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.

Do you need to see the site first?

That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

How much does the work cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.

How many days will you need on site?

The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Protect fresh coloured sealant from dust and handling
  • Use one colour standard across multi-site work
  • Agree the sealant colour early and write it into the specification
  • Avoid abrasive pads on coloured sealant

Include coloured sealant in planned building checks. Watch for cracks, peeling or discolouration, and plan resealing before it looks tired.

Include coloured joints in a planned maintenance cycle. Replacing them on a schedule keeps finishes looking right across the building.

Surface by surface

Cladding panels

Where panels vary in colour, the joint colour is agreed for the whole elevation. Sometimes a mid-tone suits better than matching one panel.

Office fit-outs

Office joinery and frames normally follow a colour scheme. We choose sealant colours to suit as specified.

For managing agents and facilities managers

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Colthrop. Several sites can go on one quote, which keeps the paperwork simple.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Coloured sealant around Colthrop: what changes locally

Colthrop has at least three named business or industrial parks inside a 3-mile radius. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints; brand colours often come into it. Colthrop is in the South East, one of the UK’s drier regions. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.

In a retail centre such as 9Yards Retail Park, 3 miles west of Colthrop, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish. Trade counters and showrooms on estates such as Pipers Lane Industrial Estate (less than half a mile south-west of Colthrop) need neat joints where customers see them.
