Common questions from Amport clients

Is a smaller place like Amport outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Can you match sealant colours for premises in Amport?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Available colours for the product are confirmed with the quote.

Can you take on work for an FM or managing agent?

Yes. A large share of our work comes through facilities managers, managing agents and landlords. We can work to your instruction process and site rules.

How is commercial sealant work priced?

Send what you have, even a few photographs and rough lengths. We follow up with questions or a visit where needed, and then a fixed quote for the agreed scope.

What guarantee do you give on resealing?

A 12-month guarantee covers the workmanship. Looking after the joints as we advise helps them last.

Do you seal on top of existing sealant?

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

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Sealant specialists in Amport

Pricing a commercial reseal is a short process. Our quote form takes photos, drawings or a schedule of the areas and you can also speak to us on 01277 525 020 or email a schedule or drawings to talk it through. If the joints need seeing in person, a site visit comes first, followed by a fixed quote rather than an estimate that drifts. The enquiries we see most involve greasy, split joints in a kitchen or tea point and earlier reseals applied straight onto the failed bead, across kitchen worktops and splashbacks, external facade joints and window and door perimeters. Most enquiries from Amport start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Quotes for commercial sealant in Amport can come from photographs and a joint schedule, or from a walk-round, with the scope listed so everyone knows what’s included.

Rural business units near smaller places such as Amport are frequently converted agricultural buildings. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Leave it or put it right?

Some managers wait for a fit-out before touching the mastic. That’s reasonable for internal joints that are just tired-looking, 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. Converted and older buildings near places like Amport tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Why us?

  • Failed material removed, not covered up
  • CHAS accredited
  • CSCS-carded applicators
  • A Constructionline member, so easy to vet

Take a look at what affects the cost and our accreditations.

Keeping the joints sound

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

  • Keep abrasive pads and scrapers off resealed joints
  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Note dates and locations of sealant work for future planning
  • Have extract fans checked so wet areas dry out

Our workmanship on each job is backed by a 12-month guarantee. File the handover note with the building records.

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.

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. If others near Amport need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. We start with the evidence: photos, drawings or a look on site.
  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. 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. Completed areas are signed off with you under our 12-month guarantee.

Before we start on site

  • Move anything stored against the joints
  • Agree which areas must stay open
  • Let us know about inductions and permits

Request a quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

What sets the cost

These are the things that shape the price:

  • Whether the work must be split into stages
  • Joint width, depth and condition
  • Specialist products, such as fire-rated or hygienic sealants
  • Distance, for remote addresses

A quote for sealant joints depends on quantities, condition and access. Call for a quote.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • When you need the work done
  • Specification clauses that apply
  • The postcode of the building
  • Asbestos survey details if the building is older

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or email a schedule or drawings.

General trades versus a specialist

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Sealant on show in Amport’s commercial buildings

At least three named trading, business or retail sites lie within about 3 miles of Amport. Each new occupier on a park like these tends to refit, from reception to staff kitchen; brand colours often come into it. The South East is one of the drier parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it.

Premises within reach of Grateley station (2.7 miles south-west of Amport) often have busy frontages where joints are seen by everyone passing. On a business park such as Weyhill Business Park, which lies north of Amport, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters. If you have premises on more than one site, say at Weyhill Business Park and Plot 5 Andover Business Park, one contractor and one quote can cover both.

How the job changes by surface

Washrooms and toilets

Washroom joints take water, cleaning chemicals and constant use. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, with phased work so some facilities stay open.

Commercial kitchens and tea points

A smooth, continuous joint is easier to keep clean. We seal to a neat, cleanable finish and work around service times you agree with us.
