How we handle commercial sealant contractors in Wickham Common

A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely and the faces are cleaned until they’re sound and dry, with no dust or grease left. Primer is used wherever the manufacturer calls for it on that surface. If you have wall and floor joints that have lost their seal and gaps behind commercial kitchen worktops and sinks, we can put it right, on kitchen worktops and splashbacks, external facade joints and window and door perimeters alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Wickham Common is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In an occupied building in Wickham Common, the job is planned so areas stay in use: we agree the order with you and hand back each area with its cure time.

Commercial sealant work around smaller places like Wickham Common tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Each has kitchens, washrooms and frames whose joints need renewing in time.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Sealant on show in Wickham Common’s commercial buildings

The 3 miles around Wickham Common take in at least three named trading estates, business parks or retail parks. Each new occupier on a park like these tends to refit, from reception to staff kitchen; brand colours often come into it. Wickham Common sits in one of the drier corners of the country, the South East. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it.

In hotels such as The Old House Hotel (1 mile north-west of Wickham Common), refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. Premises within reach of Fareham station, 2.8 miles south of Wickham Common, often have busy frontages where joints are seen by everyone passing.

What happens if it’s left?

Some managers wait for a fit-out before touching the mastic. For internal joints that are only cosmetic, that can make sense, but a joint letting water in now keeps doing damage until the refurb arrives. Splitting the scope into now and later is often the sensible compromise. Older rural buildings around Wickham Common move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

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 you’ll have a fixed figure to work with.

What you get with us

  • A fixed quote before work starts
  • CHAS accredited contractor
  • Failed material removed, not covered up
  • RAL and finish matching where the product range allows

Take a look at how commercial sealant jobs are priced and our accreditations and insurance.

How the quote is worked out

Before we quote, we look at:

  • The total length or number of joints
  • How accessible the joints are
  • Joint width, depth and condition
  • Specialist products, such as fire-rated or hygienic sealants

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

Sending details for a quote

A few photos plus some basic facts will normally do. Please tell us:

  • The type of building and who uses it
  • Clear photos of the problem areas
  • Anything awkward about access or site hours
  • The postcode of the building

For a fixed quote, call 01277 525 020 or send photos by email with the site address and an outline of the work. Our quote form is another easy route.

FAQs: Wickham Common

Is Knowle Village Business Park, near Wickham Common, within your area?

Yes. Estates, retail parks and business parks around Wickham Common, Knowle Village Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Is Wickham Common too small for you to travel to?

Not at all. Wickham Common is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Can you supply RAMS and insurance details?

Let us know your requirements when you ask for a price, and the paperwork is confirmed with the quote. For older buildings we will ask for the asbestos register, plus your site induction rules.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

How many days will you need on site?

It depends on the scope, but the work normally takes a few hours to several days on most single sites, depending on joint lengths and access. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Could the old sealant in an older building contain asbestos?

In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and if something is suspected, work stops until it’s tested.

Do you take on multi-site sealant work?

Yes. We take on runs of jobs across portfolios as well as single sites, priced site by site or as one programme.

Doing it in-house

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Common problems we fix in Wickham Common

In wet areas the enemy is usually mould rather than movement. Constant moisture, cleaning chemicals and weak extraction let mould grow into the sealant. Replacement with a sanitary anti-mould silicone is the lasting answer.

Most enquiries start with one or more of the following:

  • External beads that have gone brittle and cracked
  • Expansion joints with the sealant torn out
  • Untidy joints in a reception, shop floor or lobby
  • Gaps behind commercial kitchen worktops and sinks

Units at places like Broadcut Retail Park (to the south of Wickham Common) are refitted as brands change, and the joints have to suit each new scheme.

Before you book anyone

  • Their plan for phasing and protecting the area
  • Whether old or failed sealant will be cut out, not overlaid
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Whether primer will be used where the manufacturer specifies it

How to choose a sealant contractor

Honest limits

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Faulty windows rather than failed perimeter sealant
  • A dripping trap, valve or pipe behind a fitting
  • A failed roof covering or waterproofing membrane

Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

What we seal

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