Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a building around Eastergate, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. You send photographs, drawings or a list of the joints and areas involved.
  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. 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.

Sealant specialists in Eastergate

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. Before anything is cut out, we ask for the asbestos register or survey, because the duty to manage asbestos sits with the dutyholder. Anything suspect is left alone until it has been tested (removing asbestos-containing materials isn’t something we do). If you are dealing with frame sealant that has cracked, shrunk or pulled away and messy, uneven beads from earlier work that let the building down, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Eastergate is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Quotes for commercial sealant in Eastergate can come from photos and a joint schedule, or from a walk-round, with the scope listed so everyone knows what’s included.

Commercial sealant work around smaller places like Eastergate tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.

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

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • The product specified
  • Whether old sealant has to be cut out first
  • Site requirements such as inductions and permits
  • Whether the work must be split into stages

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • Any specification or named product
  • Your programme or deadline
  • Approximate linear metres or a joint schedule
  • The asbestos register, for older buildings

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to ring 01277 525 020 or email drawings and photos.

What Eastergate’s businesses ask us to seal

At least three named trading, business or retail sites lie within about 3 miles of Eastergate. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal; brand colours often come into it. A number of hotels sit less than 2 miles from Eastergate. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet, with rooms done in turn while the rest stay let.

Parks like Sussex Business Village, 1.7 miles to the east of Eastergate, see tenants come and go, and every move-in brings joints to seal. Premises within reach of Barnham station (to the south-east of Eastergate) often have busy frontages where joints are seen by everyone passing.

Eastergate is about 4 miles north of Bognor Regis, in West Sussex. We send applicators to Eastergate for sealant joints. Eastergate is one of 373 places in West Sussex on our list for sealant joints. There’s a separate page for Portsmouth, about 19 miles away.

Different surfaces, different methods

Washrooms and toilets

Black sealant in a toilet block is normally beyond cleaning. Replacement is the fix: strip, clean, dry and reseal, planned so the building keeps enough facilities in use.

Commercial kitchens and tea points

Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. They’re degreased thoroughly before resealing.

FAQs: Eastergate

Can you work at a site such as Sussex Business Village, by Eastergate?

Yes. We cover Eastergate and the area around it, including industrial estates, business parks and retail parks such as Sussex Business Village. Photos and a short description are enough for a first look.

Do hotels near Eastergate have to close for sealant work?

Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we’ll plan around them.

Will the building have to shut during the work?

It’s normal for us to work in occupied buildings. Only the area being sealed is closed, and the sequence is agreed in advance, until its cure time has passed.

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.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Does commercial sealant work come with a guarantee?

It’s backed by our 12-month guarantee. Should a joint we sealed give trouble during those 12 months, let us know and we will look at it.

Why act early in Eastergate

Reactive resealing, a leak at a time, tends to cost more overall than a plan. A planned programme groups work by building or area, cuts repeat visits and gives you a budget figure. We will suggest an order, worst sealant joints first. Halls, stores and units around places like Eastergate may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Signs you need commercial sealant contractors in Eastergate

The wrong sealant in the wrong place is a common cause of early failure. 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. BS 6213 gives guidance on choosing construction sealants.

Look out for the following:

  • External beads that have gone brittle and cracked
  • Untidy joints in a reception, shop floor or lobby
  • Damp patches where an external joint has failed
  • Frame mastic that has hardened and come away from the wall

For a shop at a centre such as Arun Retail Park, 2.9 miles south of Eastergate, tidy joints at counters and displays matter as much as the fixtures.

How to choose a sealant contractor

Aftercare for building managers

After handover, a little attention goes a long way:

  • Look at the sealant around anything that has been moved or replaced
  • Keep a record of which joints were resealed and when
  • Put external and wet-area joints on a regular inspection round
  • Keep abrasive pads and scrapers off resealed joints

Let your cleaning contractor know what’s new. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces; a mild cleaner is all most joints need.

Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.
