Coloured sealant across Sperberry Hill

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • Whether old sealant has to be cut out first
  • Any access equipment needed
  • Quantities, in metres or numbers
  • Site requirements such as inductions and permits

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

What to include in your enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • Clear photos of the problem areas
  • What the building is and how it’s used
  • Rough lengths or quantities, or drawings if you have them
  • Anything awkward about access or site hours

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

Coloured sealant for commercial buildings in Sperberry Hill

Shop fits, hotels and offices are where colour-matched sealant earns its place. A mismatched bead can make good joinery look unfinished, even when the seal is sound. The aim is a colour from the product’s range that disappears into the surface. We work on shop-fit joinery and counters, natural stone and brick and hotel bathrooms and public areas, and the usual reasons a site gets in touch are colour changes after a rebrand or refit and stained or mouldy coloured joints in washrooms. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Sperberry Hill is the same: the right product in a properly prepared joint.

In and around smaller places such as Sperberry Hill, the commercial buildings we are asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Your questions answered

Is Sperberry Hill 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. Where we can, we group nearby jobs to make the most of each trip.

Can the sealant on our Sperberry Hill premises match the finishes?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Available colours for the product are confirmed with the quote.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

On site: what to expect

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Jobs in and around smaller places like Sperberry Hill are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. The sealant type is chosen for the joint first, then the colour.
  2. We compare your RAL reference or sample with the colours made for that sealant.
  3. Where colour is critical, a sample bead can be agreed in a discreet spot.
  4. We take out the existing bead, clean the joints and fit backing.
  5. The coloured sealant is applied and tooled with clean, masked edges.

What we need from you

  • Move anything stored against the joints
  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings

Why deal with it now?

A brand roll-out or multi-site fit-out benefits from a consistent sealant colour. Setting one product and colour for every site avoids variation from one fit-out to the next. One visit to deal with every failing joint makes more sense than several trips to a place like Sperberry Hill, rather than one at a time. Photos of every joint help us quote for the whole job.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What you get with us

  • Over 20 years of commercial sealing
  • 12-month guarantee on workmanship
  • A fixed quote before work starts
  • Specification-led, product-correct work

When to call us in Sperberry Hill

Most enquiries start with a joint that looks wrong: a pale bead on a dark frame, or an old seal that has discoloured. A better-matched colour fixes the appearance without changing the joint’s job.

Look out for the following:

  • Previous reseals that don’t match the original
  • Marked sealant in hotel bathrooms
  • Joints that need to match a new RAL frame colour
  • Failed coloured sealant that has split or peeled

For a hotel such as Redcoats Farmhouse Hotel, 0.6 miles east of Sperberry Hill, the colour of a joint at the bar or the bath matters to the look of the room.

Comparing quotes

  • Whether their applicators hold CSCS cards
  • Which product they’ll use, and why it suits the joint
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Proof of insurance
