Commercial sealant contractors for Little London sites

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

How the quote is worked out

The price varies from site to site. Expect it to depend on:

  • The size and state of each joint
  • The site’s rules and procedures
  • Any access equipment needed
  • Specialist products, such as fire-rated or hygienic sealants

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Before you send an enquiry

To price the job accurately, we need to understand the site. Useful things to include:

  • Any specification or named product
  • Access details, including height
  • Any dates the work must fit around
  • Asbestos survey details if the building is older

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Sealant specialists in Little London

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before old sealant is disturbed. Anything suspect is left alone until it has been tested. If you’re dealing with frame sealant that has cracked, shrunk or pulled away and layers of sealant, all of them failing, we can help, on external facade joints, movement joints in walls and floors and floor and threshold joints alike. For commercial sealant work in Little London, you deal with one contact from quote to sign-off, whether it’s one building or several.

We price commercial jobs in Little London from photographs, drawings or a site visit, and the scope is set out in writing.

A job in a smaller place like Little London is normally a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What Little London’s businesses ask us to seal

The 3 miles around Little London take in at least three named trading estates, business parks or retail parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal. Little London is in the South East, one of the UK’s drier regions. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up.

A unit on an estate like Glenmore Trade Park, 2.1 miles to the south-west of Little London, usually has an office front, a trade counter and staff facilities with joints of their own. For premises near Andover station, 2.9 miles south-west of Little London, footfall is part of the plan: work is phased so shops and offices keep trading.

Little London is about 3 miles north-east of Andover, in Hampshire. Looking for commercial sealant contractors in Little London? We can help. 723 places across Hampshire fall within our area, including Little London. Our Southampton page has more on work in that area.

Different surfaces, different methods

Shop fronts and retail fit-outs

In retail, sealant is on show. Counters, display units, shopfront frames and floor trims all need a neat line, often in a colour to suit the brand finish. We will confirm the colours available for the specified product.

Facade and cladding joints

Panel joints on cladding and rendered facades open and close with the temperature. They need a sealant with the right movement capability, laid at the right depth. Access, such as scaffold already up, is agreed before the price is fixed.

Questions about Little London

Do you cover business parks and estates near Little London, such as Glenmore Trade Park?

Yes. Our area takes in Little London and its surroundings, with estates and business parks such as Glenmore Trade Park included. To start, just phone 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Do you offer colour-matched sealant for buildings in Little London?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Send colour references or photos and we will confirm what’s available for the product.

Do you work for facilities managers and managing agents?

Yes. Use our quote form to send the site details, or phone or email us, and tell us what site paperwork you need.

Is failed sealant stripped out, or sealed over?

The old bead is stripped out first. After that come cleaning, primer where needed, backing and the new sealant.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators.

Does commercial sealant work come with a guarantee?

Each job sits under our 12-month guarantee from handover. Looking after the joints as we advise helps them last.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Little London can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. First, details reach us through the quote form or a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.

Before we start on site

  • Agree which areas must stay open
  • Share the asbestos register for older buildings
  • Have the specification and drawings to hand

Request a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or send photos by email.

What happens if it’s left?

Some low prices are low because nothing gets cut out. New sealant laid on old silicone has nothing to bond to, so it peels. Our prices always include removal of the failed bead and full joint preparation, because that’s what makes the new bead last. For buildings around smaller places like Little London, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

What you get with us

  • One number for every site we cover
  • Products installed to the manufacturer’s instructions
  • Sealing commercial buildings since 2005
  • RAL and finish matching where the product range allows

Take a look at our cost guide or how we’re accredited.

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Signs you need commercial sealant contractors in Little London

If sealant tears through its centre, it has failed cohesively. That usually means the joint stretched further than the product could cope with. The same product in the same joint tends to fail the same way, which is why we look at the joint design as well.

Common reasons buildings call us in:

  • A top-up bead over failed sealant, now lifting
  • Weathered facade sealant that no longer flexes
  • Gaps behind commercial kitchen worktops and sinks
  • Smeared sealant across finishes from a rushed job

Occupiers with premises at both Glenmore Trade Park and Walworth Business Park could have the sealant at each handled under one quote.
