Sealant applicators in The Hummicks

If you look after more than one building, a single sealant contractor saves a lot of chasing. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. To get a programme moving in The Hummicks, phone 01277 525 020 or send details through our quote form with the site addresses. We work on movement joints in walls and floors, window and door perimeters and external facade joints, and what we’re called in for most is mouldy silicone around WCs, urinals and vanity tops and window and door perimeter joints that have cracked open. For commercial sealant work in The Hummicks, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

The most common commercial job in The Hummicks is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Business units in the countryside around places like The Hummicks are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.

Our workmanship is guaranteed for 12 months, in The Hummicks as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Looking after the joints

For the best life from the joints:

  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Respect the cure time before reopening an area
  • Check sealant as part of routine building inspections
  • Keep a record of which joints were resealed and when

Good ventilation keeps wet-area sealant in better condition. Extraction that isn’t working keeps the joints wet, which is how mould gets back in. It’s worth having fans checked while the sealant is fresh.

Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. At that point it’s a repair job rather than a reseal.

Work for main contractors and building owners

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

When something else is needed

Being straight saves everyone time. Fresh joints won’t solve:

  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • Water from a services leak rather than a joint
  • Old mastic that tests positive for asbestos

Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

What we seal

  • Kitchen worktops and splashbacks
  • Washrooms and tea points
  • Movement joints in walls and floors
  • Window and door perimeters
  • Floor and threshold joints
  • External facade joints

When to call us in The Hummicks

Every sealant joint is a maintenance item. Its life comes down to movement, UV and weather, how it’s cleaned, how much traffic passes it and what was used in the first place. In commercial buildings those factors tend to act together.

Clients typically get in touch after noticing one or more of the following:

  • Window and door perimeter joints that have cracked open
  • Weathered facade sealant that no longer flexes
  • Water staining near frames, panels or ceilings
  • Messy, uneven beads from earlier work that let the building down

A hotel such as Montagu Arms Hotel, 0.9 miles west of The Hummicks, shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

What your quote should include

  • The terms of the workmanship guarantee
  • Will failed sealant be removed rather than covered?
  • Will RAMS and insurance details be available?
  • The named product and why it was chosen

Our contractor checklist

Diagnose, treat, sign off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. Smaller jobs around The Hummicks can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations, and a site visit is booked where it helps.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

Getting the site ready

  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings
  • Explain the parking and delivery arrangements

Ask for a quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Doing it in-house

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Sealant on show in The Hummicks’s commercial buildings

The Hummicks lies within about 2 miles of the sea. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. A matched colour is only half the brief on an exposed frontage. Less than 3 miles from The Hummicks there are two named estates and business parks. Each new occupier on a park like these tends to refit, from reception to staff kitchen.

Industrial estates such as Hardley Industrial Estate (to the north-east of The Hummicks) have offices, trade counters and welfare areas whose sealant ages like any other building’s. A business with units at Hardley Industrial Estate and Glenmore Business Park needn’t use two contractors for its sealant.

Questions we are asked in The Hummicks

Is The Hummicks too far out for you?

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.

Will our hotel in The Hummicks need to close for the work?

In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

How do you keep disruption to occupiers down?

Most of the buildings we work in stay occupied. Only the area being sealed is closed, and the sequence is agreed in advance for as long as the cure needs.

What about asbestos in old mastic?

We check the asbestos register or survey before any old sealant is disturbed. The duty to manage asbestos sits with the dutyholder and removing it isn’t something we do.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
