Common problems we fix in Hatherden

Washrooms and kitchens wear sealant out in their own way. Constant moisture, cleaning chemicals and weak extraction let mould grow into the sealant, and once established it rarely cleans out. Replacement with a sanitary anti-mould silicone is the lasting answer.

Look out for the following:

  • Black mould through washroom sealant that won’t clean off
  • Greasy, split joints in a kitchen or tea point
  • Frame mastic that has hardened and come away from the wall
  • Wall and floor joints that have lost their seal

Shops and cafés around stations like Andover station, 2.9 miles south of Hatherden, trade from early, so work is timed around them.

Questions to ask before you book

  • Proof of insurance
  • Which product they’ll use, and why it suits the joint
  • Will CSCS-carded applicators be on site?
  • Their plan for phasing and protecting the area

Choosing a commercial sealant contractor

Sealant applicators in Hatherden

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; phasing keeps some washrooms, kitchens or entrances available while others are done. That applies whether the building is an office, a shop, a hotel, a college or a care home. We work on movement joints in walls and floors, window and door perimeters and washrooms and tea points, and the failures we’re asked to look at most are untidy joints in a reception, shop floor or lobby and frame sealant that has cracked, shrunk or pulled away. A single leaking joint is often how a building in Hatherden first comes to us: we look at the rest while we’re there and tell you what we find.

A lot of what we do in Hatherden is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.

Work in smaller places such as Hatherden tends to come one building at a time: a pub kitchen, a hall, a small office. We’ll want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.

Work we carry out in Hampshire comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or send details through our quote form and we will arrange a return visit.

What happens if it’s left?

Spot repairs have their place. Where the remaining sealant is just as old, it tends to fail soon after, and a second visit means paying for access and set-up again. Where it helps, we quote a patch and a full reseal side by side. Halls, stores and units around places like Hatherden may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you’re ready.

From enquiry to sign-off

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. For work around Hatherden, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. First, details come to us: photographs, drawings or a schedule of the areas.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Confirm the product named in the specification
  • Arrange parking or a loading space

Questions about Hatherden

Can you match sealant colours for premises in Hatherden?

Yes, we can typically get close to most finishes from the product’s colour range. The quote lists the colours the product is made in.

Is Hatherden off your patch?

No. Places such as Hatherden are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

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.

Does commercial sealant work come with a guarantee?

It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Do you check for asbestos before removing sealant?

It can, on some older buildings. So we check the register first and stop work on anything suspect until it’s tested. HSE guidance on asbestos is a useful reference.

Do you work for facilities managers and managing agents?

Yes. You can send details through our quote form, and tell us what site paperwork you need.

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Quantities, in metres or numbers
  • How much existing material needs removing
  • The site’s rules and procedures
  • Location, for remote and island sites

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Details that help us quote

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

  • When you need the work done
  • The type of building and who uses it
  • The asbestos register, for older buildings
  • Access details, including height

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Maintenance after handover

Problems stay small when the joints are checked regularly. In particular:

  • On pre-2000 buildings, share the asbestos information before work starts
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Put external and wet-area joints on a regular inspection round
  • Don’t let cleaning or traffic back on before the cure time is up

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

Once sealant fails in a movement joint, grit and debris get in. The joint can no longer close, so its edges crack or spall. At that point it’s a repair job rather than a reseal.

Owners, agents and contractors

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
