Commercial sealant contractors across Brook Street

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Your questions answered

Is Brook Street too far out for you?

Not at all. Brook Street is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Will you take on work at estates like Warley Hill Business Park, close to Brook Street?

Yes. Estates, retail parks and business parks around Brook Street, Warley Hill Business Park among them, are all within reach. A few photos and the unit address let us price the work.

Is it fine to apply new sealant on top of old?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Does commercial sealant work come with a guarantee?

Our workmanship is guaranteed for 12 months. Public liability insurance is in place too.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards.

Can one contractor look after sealant on all our buildings?

Yes. We take on runs of jobs across portfolios as well as single sites, priced site by site or as one programme.

Commercial sealant contractors in Brook Street

Pricing a commercial reseal is a short process. Our quote form takes photographs, drawings or a schedule of the areas. If the joints need seeing in person, a site visit comes first, followed by a fixed quote rather than an estimate that drifts. Most enquiries involve untidy joints in a reception, shop floor or lobby and leaks that seem to come through a sealant line, across window and door perimeters, washrooms and tea points and floor and threshold joints. Most enquiries from Brook Street start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Occupied buildings in Brook Street need the work phased: we agree the order with you and hand back each area with its cure time.

Rural business units near smaller places such as Brook Street are frequently converted agricultural buildings. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Honest limits

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

  • Faulty windows rather than failed perimeter sealant
  • Walls or slabs moving more than any sealant can take
  • Old mastic that tests positive for asbestos

If you’re not sure, just phone 01277 525 020 or email us and we will give you a straight answer before you book.

What we seal

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

Frontages, fit-outs and joints in Brook Street

There are a number of hotels within about 2 miles of Brook Street. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter, with rooms done in turn while the rest stay let. Two named trading, business or retail sites lie within about 3 miles of Brook Street. Each new occupier on a park like these tends to refit, from reception to staff kitchen; brand colours often come into it.

Parks like Warley Hill Business Park, 1.1 miles to the south-east of Brook Street, see tenants come and go, and every move-in brings joints to seal. Sites a few miles apart, such as Warley Hill Business Park and Childerditch Industrial Park, can share one programme and one point of contact. Offices and shops close to stations such as Brentwood station (to the east of Brook Street) tend to be busy all day, so sealant work is planned around opening hours.

Brook Street is about 2 miles south-west of Brentwood, in Essex. We cover commercial sites throughout Brook Street. Our Essex coverage takes in 644 places. We also cover London, some 18 miles away.

For managing agents and facilities managers

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.

Our process

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. For a building around Brook Street, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. We strip the failed bead and prepare both faces of the joint.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Before we start on site

  • Let us know about inductions and permits
  • Have the specification and drawings to hand
  • Send your site hours and access windows

Quotes

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Why it’s worth doing now in Brook Street

A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. Often the fitting is sound and the joint is the only thing letting it down. A careful reseal is a far smaller undertaking than replacement, and we’ll say so if the frame or fitting is life-expired. Converted and older buildings near places like Brook Street tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

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.

Why us?

  • One phone line for London, the South East and Scotland
  • Failed material removed, not covered up
  • RAL and finish matching where the product range allows
  • 12 months’ guarantee on every job

See our cost guide and how we’re accredited.

Looking after the joints

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Keep abrasive pads and scrapers off resealed joints
  • Note dates and locations of sealant work for future planning
  • Add sealant to the planned maintenance inspection list
  • Keep barriers up until the new sealant has cured

Brief your cleaning team on the joints that have been resealed. Scourers, blades and harsh products shorten a bead’s life, while a neutral cleaner and a soft cloth do no harm.

Sealant installed at the same time usually fails in sequence. A few splits this year normally mean more next year. We can assess the lot and suggest what to do now and later.
