Our commercial sealant contractors service in East Sussex

Having a single contact for all your sites makes sealant far simpler to manage. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes, run the same way on every site: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. For sites in East Sussex, the quickest start is to speak to us on 01277 525 020 or email us with a list of addresses. We work on movement joints in walls and floors, floor and threshold joints and window and door perimeters, and the usual reasons a site gets in touch are greasy, split joints in a kitchen or tea point and earlier reseals applied straight onto the failed bead.

Before we leave any area, 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.

We start with the evidence: photographs, drawings or a look on site.
A fixed quote follows, with removal and preparation included.
We agree the order of work, access windows and site hours with you.
The failed sealant comes out and the faces are prepared, with primer where required.
Depth is set with backing, then the sealant is applied, tooled and the area tidied.
Completed areas are signed off with you under our 12-month guarantee.

Where commercial joints are in East Sussex

Shop fits, office refurbishments and hotel refits in towns such as Eastbourne, Hastings and Bexhill-on-Sea all leave joints that need sealing. Where the joint is on show, a colour that suits the finish is part of the job.

London and the South East are among the drier parts of the UK, but external sealing in East Sussex still needs a dry joint and the right temperature, and damp or frosty mornings can hold it up. On the coastal side of East Sussex, sea-facing elevations normally show failed joints first, so they’re worth inspecting more often.

Eastbourne: For premises near Hampden Park station, 0.7 miles north-west of Eastbourne, footfall is part of the plan: work is phased so shops and offices keep trading. Occupiers with premises at both Hammond Industrial Estate and Britland Industrial Estate could have the sealant at each handled under one quote.

Keeping the joints sound

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

Keep a record of which joints were resealed and when
Ask fit-out and M&E contractors to report any sealant they disturb
Add sealant to the planned maintenance inspection list
Keep abrasive pads and scrapers off resealed joints

New joints need their full cure time before they take water, cleaning or traffic. That time depends on the product, the temperature and the joint depth. Leaving the area closed until then keeps the bead neat.

An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Cleanability is something environmental health officers pay attention to, so sound, smooth joints matter.

When something else is needed

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

Leaks from pipework, wastes or valves (that’s plumbing)
Old mastic that tests positive for asbestos
Misted, cracked or failed glazing units (a glazier’s job)

Surface by surface

Movement joints in walls and floors

Floor joints that take trolleys or forklifts need a tougher filler or sealant. The choice comes down to how much the joint moves and what runs over it, and tell you if the edges need repairing first.

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. The design and sign-off of fire stopping belong to the designer and building control.

What happens if it’s left?

Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. In many cases the element is fine and only the seal around it has given up. A careful reseal is a far smaller undertaking than replacement.

What your quote should include

How they handle RAMS and site documents
Their public liability cover
Whether primer will be used where the manufacturer specifies it
Is depth set with backing rod, or bond-breaker tape in shallow joints?

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Your questions answered

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Is East Sussex in your area?

Yes. East Sussex is in our area. To discuss a job, call 01277 525 020 or send details through our quote form.

How many days will you need on site?

That varies with the scale of the job, though a typical visit usually takes a few hours to several days on most single sites, depending on joint lengths and access. For bigger or phased jobs, we will set out a timescale with the quote.

Is the old sealant taken out first?

Full removal is part of every quote. A bead laid on old silicone peels away.

Which site documents can you send us?

We will confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
