About our commercial sealant contractors in Longlane

Commercial occupiers rarely want a floor out of action for sealant work. Work is scheduled around the site hours and access windows you give us. That applies whether the building is an office, a shop, a hotel, a college or a care home. Site teams most often ask us about expansion joints with the sealant torn out and frame sealant that has cracked, shrunk or pulled away, across floor and threshold joints, washrooms and tea points and movement joints in walls and floors. A single leaking joint is often how a building in Longlane first comes to us: we look at the rest while we are there and tell you what we find.

Occupied buildings in Longlane need the work phased: washrooms in turn, floors in sections and entrances kept open.

A job in a smaller place like Longlane 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. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Building owners, agents and FMs in Longlane

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Put external and wet-area joints on a regular inspection round
  • Make sure ventilation in wet areas is switched on and working
  • Log reseals in the O&M or maintenance records

Later works are the usual way new joints get damaged. When fittings are moved or cabling added, the sealant nearby is easily disturbed and the joint gets left open. Where work has disturbed a joint, just call the office on 01277 525 020 or use the quote form for a quote.

Occupiers often notice failing sealant before the facilities team does, and it reflects on how the building is run. Replacing it on a planned cycle keeps complaints down.

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Misted, cracked or failed glazing units (a glazier’s job)
  • Suspect materials that need testing and specialist removal
  • Roof leaks that only look like a joint problem

If you’re not sure, just ring 01277 525 020 or send photos by email and we will give you a straight answer.

Where we work in Longlane

  • Kitchen worktops and splashbacks

From enquiry to sign-off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes part of a day on a small job and longer where several buildings or phases are involved, and our waste is bagged and taken away as we go. If others near Longlane need work, visits can be combined. A fixed quote is given before anything starts.

  1. Send details through our quote form, or ask for a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Where parts of the building must stay open, the work is phased.
  4. Old sealant is cut out completely, never sealed over.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Before we start on site

  • Move anything stored against the joints
  • Point out any areas we must not close
  • For older buildings, check the asbestos register before work

Frontages, fit-outs and joints in Longlane

The South East is one of the drier parts of the UK. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. Longlane has at least three named business or industrial parks inside a 3-mile radius. Sites like these see regular refits, with shopfronts, offices and staff areas to seal.

Offices and shops close to stations such as Newbury Racecourse station (3.3 miles south of Longlane) tend to be busy all day, so sealant work is planned around opening hours. Occupiers with premises at both Red Shute Hill Industrial Estate and Turnpike Road Industrial Estate could have the sealant at each handled under one quote. On estates like Red Shute Hill Industrial Estate, under half a mile east of Longlane, the office and welfare end of each unit has its own sealant to maintain.

Leave it or put it right?

It can be tempting to hold sealant work back until the next refurbishment. That’s reasonable for internal joints that are just tired-looking, but external and wet-area joints that already leak shouldn’t wait. Splitting the scope into now and later is often the sensible compromise. For buildings around smaller places like Longlane, 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.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
