Common questions from Hill Brow clients

Do you offer colour-matched sealant for buildings in Hill Brow?

Yes, we can normally get close to most finishes from the product’s colour range. Send colour references or photographs and we’ll confirm what’s available for the product.

Does your area include sites such as Upper Adhurst Industrial Park, near Hill Brow?

Yes, sites like Upper Adhurst Industrial Park are within our area, along with the rest of Hill Brow. Send details of the unit and the work through our quote form for a quick quote.

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 we don’t remove asbestos-containing materials.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Is failed sealant stripped out, or sealed over?

Removal of the failed sealant is always part of the job. Laying new silicone on old gives it nothing to grip; the faces are then cleaned and prepared.

Do you work for facilities managers and managing agents?

Yes. You can send details through our quote form.

Is Hill Brow in your area?

Yes. We cover Hill Brow. To discuss a job, call the office on 01277 525 020 or send photos by email.

Sealant specialists in Hill Brow

We’ve applied sealant on commercial sites for over 20 years, and the documents buyers ask for are ready: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. If your site needs RAMS, an insurance certificate or CSCS details, say so and we’ll confirm with the quote. We work on external facade joints, floor and threshold joints and movement joints in walls and floors, and the failures we’re asked to look at most are smeared sealant across finishes from a rushed job and movement joints packed with grit and debris. One point of contact handles commercial sealant work in Hill Brow from the first photos to the final walk-round, for single jobs and planned programmes alike.

We price commercial jobs in Hill Brow from photographs, drawings or a site visit, with the scope listed so everyone knows what’s included.

A job in a smaller place like Hill Brow is normally a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What the job involves on each surface

Fire-rated seals where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. Fire-stopping design and sign-off sit with the designer, fire engineer or building control; we install what’s specified.

Washrooms and toilets

Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone, with phased work so some facilities stay open.

Why it’s worth doing now in Hill Brow

Some low prices are low because nothing gets cut out. New sealant laid on old silicone has nothing to bond to, so it peels. Every quote we give includes full removal and preparation, because that’s what makes the new bead last. Converted and older buildings near places like Hill Brow tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Why appoint us

  • Old sealant cut out, never sealed over
  • One phone line for London, the South East and Scotland
  • Colours chosen to suit frames, cladding or finishes where possible
  • Work to your specification and the manufacturer’s guidance

See our cost guide or our accreditations.

When to call us in Hill Brow

Resealing over the top is a false economy we come across often. New silicone has nothing to key into, so the top layer lifts, holds water and hides what’s going on. By the time it shows, there can be two or three layers to cut out.

Things that usually lead to an enquiry:

  • External beads that have gone brittle and cracked
  • Shrunken sealant along kitchen worktops and splashbacks
  • Frame sealant that has cracked, shrunk or pulled away
  • Water staining near frames, panels or ceilings

A unit on an estate like Upper Adhurst Industrial Park, 1.3 miles south-west of Hill Brow, normally has an office front, a trade counter and staff facilities with joints of their own.

Before you book anyone

  • The terms of the workmanship guarantee
  • Will CSCS-carded applicators be on site?
  • Is the sealant right for the movement and the substrate?
  • How joint depth will be controlled

Our contractor checklist

Our process

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Hill Brow can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First, details come to us: photographs, drawings or a schedule of the areas.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Preparing the site

  • Let us know about inductions and permits
  • For older buildings, check the asbestos register before work
  • Tell us which areas need to stay in use

Get a fixed quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email a schedule or drawings.

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

What sealant work can’t fix

Being straight saves everyone time. New sealant won’t cure:

  • Suspect materials that need testing and specialist removal
  • Structural cracks or movement the joints weren’t designed for
  • Broken glass or blown double-glazed units

Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Surfaces we seal

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