Frontages, fit-outs and joints in Upham

The South East is one of the drier parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. Two named trading, business or retail sites lie within about 3 miles of Upham. Each new occupier on a park like these tends to refit, from reception to staff kitchen, often in a colour the occupier specifies.

Shops and cafés around stations like Hedge End station, 4.4 miles south-west of Upham, trade from early, so work is timed around them. If you have premises on more than one site, say at Deer Park Farm Industrial Estate and Vicarage Farm Business Park, one contractor and one quote can cover both.

Upham is about 5 miles east of Eastleigh, in Hampshire. Businesses, contractors and managing agents in Upham use us for work on sealant joints. Upham is one of 723 places we cover in Hampshire for sealant joints. Our Southampton page has more on work in that area.

Commercial sealant contractors for commercial buildings in Upham

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and in an occupied building failure normally announces itself as a stained ceiling or an unhappy tenant. We are commercial sealant applicators for FMs, managing agents, landlords and contractors. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. If you have damp patches where an external joint has failed and smeared sealant across finishes from a rushed job, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Upham, that means joint design, primers and backing rod as standard.

The most common commercial job in Upham is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Work in smaller places such as Upham tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Act on the first lifting edges rather than waiting
  • Keep abrasive pads and scrapers off resealed joints
  • Keep a record of which joints were resealed and when
  • Ask fit-out and M&E contractors to report any sealant they disturb

Keep an eye out for other trades after we have gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed, and it’s easy to forget to reseal afterwards. Where work has disturbed a joint, just call the office on 01277 525 020 or email a schedule or drawings for a quote.

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. At that point it’s a repair job rather than a reseal.

When something else is needed

Some faults sit outside our scope, and we say so rather than covering them up:

  • Old mastic that tests positive for asbestos
  • Broken glass or blown double-glazed units
  • Roof leaks that only look like a joint problem

If in doubt, give us a call on 01277 525 020 or email us and we will say what we think before you book.

Joints and surfaces we work on

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

Commercial clients in Upham

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Upham can sit alongside others in a wider programme across Hampshire.

Diagnose, treat, sign off

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Upham are usually planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. Completed areas are signed off with you under our 12-month guarantee.

What we need from you

  • Point out any areas we must not close
  • Clear stock, furniture or equipment away from the joints
  • Arrange parking or a loading space

Quotes

Advice

When to call us in Upham

If sealant tears through its centre, it has failed cohesively. Usually the movement was too much for the sealant chosen. The same product in the same joint tends to fail the same way.

Common reasons buildings call us in:

  • Hardened, chalky sealant on south-facing or exposed elevations
  • Water staining near frames, panels or ceilings
  • Mouldy silicone around WCs, urinals and vanity tops
  • Wall and floor joints that have lost their seal

If you run a unit on an estate such as Deer Park Farm Industrial Estate, which lies south-west of Upham, the trade counter, offices and staff facilities have joints to look after as well as the warehouse.

What your quote should include

  • Proof of insurance
  • Whether old or failed sealant will be cut out, not overlaid
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How the joint faces will be prepared and primed

How to choose a sealant contractor

Common questions from Upham clients

Is Upham too far out for you?

Not at all. Upham is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Is Deer Park Farm Industrial Estate, near Upham, within your area?

Yes, sites like Deer Park Farm Industrial Estate are within our area, along with the rest of Upham. A few photographs and the unit address let us price the work.

When can the area be used after sealing?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Are you CHAS accredited?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

When is resealing likely to be due?

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

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

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

What do you need from us to quote?

Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. For a fixed quote, send details through our quote form.

What the job involves on each surface

Shop fronts and retail fit-outs

Shop fits put sealant right in front of clients. Counters, display units, shopfront frames and floor trims all need a neat line. Colour options are confirmed with the quote.

Fire-rated seals where specified

Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services and gaps.
