Why it’s worth doing now in Ashendon

Across a chain of shops or hotels, consistency matters. Fixing the colour reference at the start keeps every site the same across the programme. For buildings around smaller places like Ashendon, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

Why appoint us

  • Sealing commercial buildings since 2005
  • Constructionline member for supplier checks
  • Products installed to the manufacturer’s instructions
  • Joints cleaned back to sound surfaces

Coloured sealant for commercial buildings in Ashendon

We take on colour-matched work across new fit-outs, refurbishments and resealing of existing joints. When replacing old joints, the new colour normally has to match what’s already there, especially on a listed or high-profile elevation. If you have old sealant that has yellowed, darkened or faded and sealant that no longer suits recoated frames, we can put it right, whatever the surface. For commercial sealant work in Ashendon, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Business units in the countryside around places like Ashendon are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

Every job we finish is backed by a 12-month workmanship guarantee, in Ashendon as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Your questions answered

Will you take on work at estates like Rushbeds Industrial Estate, close to Ashendon?

Yes, sites like Rushbeds Industrial Estate are within our area, along with the rest of Ashendon. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Can the sealant on our Ashendon premises match the finishes?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Send colour references or photographs and we will confirm what’s available for the product.

Is Ashendon in your area?

Yes. We cover Ashendon and the rest of Buckinghamshire. To discuss a job, ring 01277 525 020 or email the details over.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Is the work guaranteed?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.

What will the job cost?

Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or email a schedule or drawings.

Our process

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes about the same time as any other sealant work, plus a little longer if a sample bead is agreed first. For work around Ashendon, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. Photos or drawings show us the finishes and joints.
  2. We send the closest colours from the product’s range.
  3. Tell us your site hours and access windows and we’ll plan around them.
  4. We prepare each joint, prime where needed and fit backing.
  5. We seal in the approved colour and tool it smooth.

Getting the site ready

  • Point out any areas we must not close
  • For older buildings, check the asbestos register before work
  • Share your working hours and any access restrictions

Maintenance after handover

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Protect fresh coloured sealant from dust and handling
  • Keep the colour details for future repairs
  • Keep harsh solvents away from visible joints
  • Plan full-run reseals on visible elevations

Use gentle cleaning methods on coloured sealant. Strong solvents and abrasive pads can dull or mark the surface.

Include coloured joints in a planned maintenance cycle. A planned reseal avoids a run of patch repairs across the building.

What we’re called out for in Ashendon

On some projects the colour was never agreed, or a substitute product was used. It seals fine but catches the eye, so someone asks for it to be changed.

Site and facilities staff are often the first to spot these:

  • Patch repairs in several different colours
  • Poorly tooled joints on visible finishes
  • Weathered sealant that no longer matches
  • Fit-outs with a sealant colour in the specification

On estates like Rushbeds Industrial Estate (2.5 miles west of Ashendon), the office and welfare end of each unit has its own sealant to maintain.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their pre-qualification and accreditations
  • Will CSCS-carded applicators be on site?

Questions to ask before you appoint anyone

How the quote is worked out

What shapes the price:

  • The total length or number of joints
  • Travel to remote or island sites
  • Whether the work must be split into stages
  • Specialist products, such as fire-rated or hygienic sealants

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Before you send an enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Any dates the work must fit around
  • The product your specification calls for
  • Anything awkward about access or site hours
  • The site address and postcode

For a fixed quote, speak to us on 01277 525 020 or send photos by email, telling us the site location and the nature of the job. You can also send details through our quote form.

Coloured sealant around Ashendon: points for this area

Ashendon lies roughly 44 miles out from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Multi-site occupiers here often want one sealant contractor across all their buildings. Ashendon sits in one of the drier corners of the country, the South East. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.
