About our commercial sealant contractors in Birling Gap

Most of the buildings we seal stay open while we’re there. Work is scheduled around the site hours and access windows you give us; phased work can also be planned so areas stay in use. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. If you are dealing with gaps behind commercial kitchen worktops and sinks and movement joints packed with grit and debris, we can put it right, on external facade joints, floor and threshold joints and kitchen worktops and splashbacks alike. Searching for sealant specialists in Birling Gap? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

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

Business units in the countryside around places like Birling Gap are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.

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.

Our process

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Rural sites near Birling Gap may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We start with the evidence: photographs, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. We agree the order of work, access windows and site hours with you.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

Before we start on site

  • Explain the parking and delivery arrangements
  • Share the asbestos register for older buildings
  • Send any specification or drawings in advance

Advice

Leave it or put it right?

Putting off a reseal normally moves the cost rather than avoiding it. Water past a frame perimeter or a washroom joint can reach plasterboard, insulation, floor coverings and the ceiling below. Dealing with it while the damage stops at the bead is the cheaper route. Converted and older buildings near places like Birling Gap tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Why us?

  • Fully insured, including public liability cover
  • 12-month guarantee on workmanship
  • Work carried out by CSCS-carded applicators
  • Fixed quotes based on photographs, drawings or a visit

How the job changes by surface

Commercial kitchens and tea points

Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. They’re degreased thoroughly before resealing, with a food-safe or hygienic product wherever food contact can happen.

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, and we install to the specification.

Commercial premises in Birling Gap

Birling Gap lies within about 1 mile of the sea. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. We choose a product rated for the exposure, then confirm the colours available for it. Birling Gap is in the South East, one of the UK’s drier regions. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.

Whatever the building in Birling Gap, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

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.

Common questions from Birling Gap clients

Is Birling Gap too far out for you?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Does the sea air around Birling Gap change the choice of sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.

Is the old sealant taken out first?

Removal comes first, every time. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.

How long does a job like this take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited and a Constructionline member.

Does weather matter for sealant work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Looking after the joints

After handover, these steps help:

  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Add sealant to the planned maintenance inspection list
  • Keep abrasive pads and scrapers off resealed joints
  • Respect the cure time before reopening an area

Put sealant on the planned maintenance checklist. A periodic look catches splits and lifting edges early, with external elevations and wet areas first in line. Should something look amiss, you can phone 01277 525 020 or send details through our quote form and send a picture.

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. That turns a sealant job into something bigger.

What we’re called out for in Birling Gap

Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed all let go sooner than they should. BS 6213 gives guidance on choosing construction sealants, and many specifications refer to it.

Any of the following is a good reason to get the joints checked over:

  • Gaps behind commercial kitchen worktops and sinks
  • Frame sealant that has cracked, shrunk or pulled away
  • Untidy joints in a reception, shop floor or lobby
  • Black mould through washroom sealant that won’t clean off

Offices and shops close to stations such as Eastbourne station (3.9 miles north-east of Birling Gap) tend to be busy all day, so sealant work is planned around opening hours.
