Why deal with it now?

Fixing joints complaint by complaint is a costly way to manage sealant. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We can help you prioritise, starting with the joints most likely to let water in. Converted and older buildings near places like Ashfield tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Why us?

  • A Constructionline member, so easy to vet
  • A range of standard colours, depending on the product
  • Colour options checked against the specified product
  • Work carried out by CSCS-carded applicators

Different surfaces, different methods

Fire-rated seals where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. Fire-stopping design and sign-off sit with the designer, fire engineer or building control.

Movement joints in walls and floors

Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. Failed seals let grit and water in, and the edges start to suffer. The new sealant is chosen for the movement and, on floors, the traffic.

When something else is needed

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Broken glass or blown double-glazed units
  • Old mastic that tests positive for asbestos
  • Cracking that needs a structural engineer to look at it

If you are not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer before you book.

What we seal

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

Shops, offices and hotels in and around Ashfield

Ashfield is within about 3 miles of the coast. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. Sea-facing elevations are usually where failed joints show first. Ashfield 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.

If you run a unit on an estate such as Crescent Industrial Estate, 1.1 miles to the south of Ashfield, the trade counter, offices and staff facilities have joints to look after as well as the warehouse. Shopping centres and retail parks such as Nursling Retail Park (1.7 miles south of Ashfield) see a steady turnover of shop fits, each leaving joints where colour and finish matter.

Ashfield is about 2 miles south of Romsey, in Hampshire. Businesses, contractors and managing agents in Ashfield can call on us for sealant joints, as part of our coverage of Hampshire. Ashfield is one of 723 places we cover in Hampshire.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a building around Ashfield, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We start with the evidence: photographs, drawings or a look on site.
  2. A fixed quote follows, with removal and preparation included.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

Before we start on site

  • Move anything stored against the joints
  • Send any specification or drawings in advance
  • Flag any permit to work we will need

Questions we’re asked in Ashfield

Will our hotel in Ashfield need to close for the work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Tell us your quiet periods and access windows and we will plan around them.

Does a coastal location like Ashfield affect which sealant is used?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Which site documents can you send us?

We confirm documents at quote stage: most clients ask for RAMS, our insurance certificate and CSCS details. Every applicator holds a CSCS card.

How long does a job like this take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

What guarantee do you give on resealing?

Our workmanship on each job is backed by a 12-month guarantee. Public liability insurance is in place too.

Common problems we fix in Ashfield

A split down the middle of the bead tells a different story. Typically the movement was too much for the sealant chosen: a bead laid too thin, an over-stretched joint or the wrong movement class. The same product in the same joint tends to fail the same way, which is why we look at the joint design as well.

If one of these sounds familiar, it’s time for a closer look:

  • Sanitary sealant that has gone black and patchy
  • Frame mastic that has hardened and come away from the wall
  • Untidy joints in a reception, shop floor or lobby
  • Weathered facade sealant that no longer flexes

Sites a few miles apart, such as Crescent Industrial Estate and Nursling Industrial Estate, can share one programme and one point of contact.

What your quote should include

  • Which product they’ll use, and why it suits the joint
  • Can the work be phased to keep areas open?
  • The terms of the workmanship guarantee
  • Their public liability cover

Choosing a commercial sealant contractor

Should maintenance staff do it?

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

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 easy to get wrong without experience.
