Your questions answered

Is Lower Froyle off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Does your area include sites such as Bentley Business Park, near Lower Froyle?

Yes. We cover Lower Froyle and the area around it, including industrial estates, business parks and retail parks such as Bentley Business Park. Photos and a short description are enough for a first look.

What guarantee do you give on resealing?

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

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.

Are you CHAS accredited?

Yes. We’re CHAS accredited and a Constructionline member.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

What about asbestos in old mastic?

We check the asbestos register or survey before any old sealant is disturbed. The duty to manage asbestos sits with the dutyholder, and we don’t remove asbestos-containing materials.

Commercial sealant contractors in Lower Froyle

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. Before anything is cut out, we ask for the asbestos register or survey, since managing asbestos is the dutyholder’s responsibility. If a material is suspected, work stops until it’s tested, and we don’t remove asbestos-containing materials ourselves. If you have shrunken sealant along kitchen worktops and splashbacks and black mould through washroom sealant that won’t clean off, we can help. A single leaking joint is often how a building in Lower Froyle first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Multi-site clients with buildings in and around Lower Froyle can put several sites on one programme, with one quote format and one point of contact.

Rural business units near smaller places such as Lower Froyle are frequently converted agricultural buildings. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.

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’re clear about what is covered before work starts.

Leave it or put it right?

A cheaper quote sometimes means the old bead stays in. Sealing over looks tidy at handover, then lifts once the joint starts moving. Our prices always include removal of the failed bead and full joint preparation. Converted and older buildings near places like Lower Froyle tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What you get with us

  • Commercial sealant work since 2005
  • RAL and finish matching where the product range allows
  • Specification-led, product-correct work
  • Our applicators hold CSCS cards

Keeping the joints sound

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Make sure ventilation in wet areas is switched on and working
  • Ask fit-out and M&E contractors to report any sealant they disturb
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Deal with small splits before they become leaks

Give fresh sealant time to cure before it’s cleaned, wetted or walked past. That time depends on the product, the temperature and the joint depth, so we confirm it for each area at handover. Leaving the area closed until then keeps the bead neat.

A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.

From enquiry to sign-off

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. Jobs in and around smaller places like Lower Froyle are typically planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  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. 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.

What we need from you

  • Let us know about inductions and permits
  • Send asbestos survey details if the building is pre-2000
  • Point out any areas we must not close

Commercial sealant contractors around Lower Froyle: how the place shapes the job

Lower Froyle has two care or nursing homes no more than 2 miles away. In care settings, a neat joint at a kitchen worktop or a lounge window is part of keeping the place easy to clean; colours can be chosen to suit the interior. Rainfall across the South East, Lower Froyle included, is lower than in many parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

Shops and cafés around stations like Bentley (Hampshire) station (to the east of Lower Froyle) trade from early, so work is timed around them. Occupiers with premises at both Bentley Business Park and Bentley Industrial Centre could have the sealant at each handled under one quote. On a business park such as Bentley Business Park, 1.5 miles to the east of Lower Froyle, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.

Lower Froyle is about 4 miles north-east of Alton, in Hampshire. We cover commercial sites throughout Lower Froyle. 723 places across Hampshire fall within our area, including Lower Froyle. Reading is covered too, around 18 miles from Lower Froyle.

Owners, agents and contractors

We work for building owners and managing agents on everything from one building to a spread of sites around Lower Froyle. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, 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.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What the job involves on each surface

Commercial kitchens and tea points

A smooth, continuous joint is easier to keep clean, which matters when environmental health officers look at a kitchen. Work is timed around the hours you give us so the kitchen isn’t out of use longer than needed.

Window and door perimeters

Internally, window boards and frame edges often have decorators’ caulk or silicone that has cracked. We use a paintable product where decorating follows and a silicone where it doesn’t, in a shade that suits the frame.
