Expansion joint sealing in Southend

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Why it’s worth doing now in Southend

Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now because damage continues. Urgent joints now, the rest later, is often the sensible plan. Older rural buildings around Southend move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Why us?

  • Fully insured
  • Over 20 years of commercial sealing
  • Specification-led, product-correct work
  • Clear, fixed quotes

How we handle expansion joint sealing in Southend

Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1, and the bead is tooled so it grips the two faces alone. The enquiries we see most involve previous reseals laid over old sealant and chipped joint edges on forklift routes, across cladding panel joints, brickwork movement joints and car park decks and ramps. Whoever orders the work in Southend, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Jobs around smaller places like Southend are planned so the whole job is done in one visit, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

A 12-month guarantee applies to all our work in Hampshire. If an installation problem shows up, phone 01277 525 020 or email the details over and we’ll arrange a return visit.

Southend: questions and answers

Is a smaller place like Southend outside your area?

No. Places such as Southend are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is hospital work, at somewhere like Knowle Hospital, something you do?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

How much does the work cost?

We don’t publish prices, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.

Is colour matching possible?

That depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

Do the joint edges need to be sound before sealing?

Broken arrises have to be put right before resealing. A bead on a broken edge soon lets go.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Doing it in-house

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Warehouse floors and decks around Southend

Less than 3 miles from Southend there are two named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint.

For a school such as Newtown Soberton Infant School, playground and building joints can be done in the holidays. Hospitals like Knowle Hospital (to the south-west of Southend) have multi-storey or surface car parks whose joints carry vehicles round the clock. Office parks like Waltham Business Park (3 miles west of Southend) have decks, ramps and clad elevations whose joints take movement every day.

Southend is about 5 miles north-west of Waterlooville, in Hampshire. Commercial clients in Southend use us for work on movement joints, as part of our coverage of Hampshire. Across Hampshire, 723 places are covered, including Southend. Portsmouth is covered too, around 8 miles from Southend.

Work on movement joints is covered throughout SO32, whatever the building. We also cover Newtown (1 mile south-west), Soberton Heath (1 mile west), Hoe Gate (1 mile south-east), Woodend (1 mile west) and Hipley (1 mile south). Further afield, our area takes in Winchester (13 miles north-west), Gosport (8 miles south), Havant (7 miles south-east), Eastleigh (10 miles west), Fareham (6 miles south-west) and Horndean (5 miles east).

Quoting for work in Southend

Each job is priced on its own details. The things that drive the figure:

  • Phasing around occupants
  • The total length or number of joints
  • Joint width, depth and condition
  • Which sealant the job calls for

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Details that help us quote

The more we know, the firmer the quote. Helpful details to send:

  • Your programme or deadline
  • A wide shot and a close-up of the area
  • Rough lengths or quantities, or drawings if you have them
  • Specification clauses that apply

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, phone 01277 525 020 or send photos by email.

On site: what to expect

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. If others near Southend need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Tell us which areas need to stay in use
  • For older buildings, check the asbestos register before work
  • Tell us what induction or permit system the site runs

Advice

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Honest limits

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Movement on a scale no sealant is meant to absorb

Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly.
