Sealant specialists in Hunton

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. Before anything is cut out, we ask for the asbestos register or survey, since managing asbestos is the dutyholder’s responsibility. Anything suspect is left alone until it has been tested, and we don’t remove asbestos-containing materials ourselves. The enquiries we see most involve mouldy silicone around WCs, urinals and vanity tops and messy, uneven beads from earlier work that let the building down, on floor and threshold joints, washrooms and tea points and kitchen worktops and splashbacks. Looking for mastic applicators who cover Hunton? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

The most common commercial job in Hunton is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Commercial sealant work around smaller places like Hunton tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

How a job runs

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Smaller jobs around Hunton can be grouped with others nearby, which keeps travel down. 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. 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. We check the work with you, and the 12-month guarantee starts.

What we need from you

  • Move anything stored against the joints
  • For older buildings, check the asbestos register before work
  • Explain the parking and delivery arrangements

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Advice

Aftercare for building managers

A few simple habits keep the new joints working:

  • Keep barriers up until the new sealant has cured
  • Make sure ventilation in wet areas is switched on and working
  • Look at the sealant around anything that has been moved or replaced
  • Check sealant as part of routine building inspections

Keep an eye out for other trades after we’ve gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed, and it’s easy to forget to reseal afterwards. Where work has disturbed a joint, just call the office on 01277 525 020 or send photos by email for a quote.

An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Environmental health officers look at how cleanable surfaces are, which makes sound joints worth keeping on top of.

Hunton: questions and answers

Is Hunton too far out for you?

Not at all. Hunton is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Does a hotel in Hunton need to shut while its sealant is renewed?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.

How do we get a quote?

Start with whatever information is to hand. We follow up with questions or a visit where needed, and then a fixed quote for the agreed scope.

Do you work for facilities managers and managing agents?

Yes, and through main contractors too. We quote, schedule and report back in the way that suits your process, with a 12-month guarantee on the workmanship.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

How do you keep disruption to occupiers down?

It’s mostly about sequence: areas are phased, access windows agreed and enough washrooms or entrances left in use. Tell us what has to stay open and we will plan the job around it.

Honest limits

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Cracking that needs a structural engineer to look at it
  • Broken glass or blown double-glazed units
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)

If in doubt, phone 01277 525 020 or email the details over and we will say what we think before you book.

Joints and surfaces we work on

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

What affects the price in Hunton

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Specialist products, such as fire-rated or hygienic sealants
  • Joint width, depth and condition
  • Working within restricted access windows
  • Removal of failed or old sealant

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

What to include in your enquiry

To price the job accurately, we need to understand the site. Send us:

  • Asbestos survey details if the building is older
  • The product your specification calls for
  • Your programme or deadline
  • How the joints are reached, and at what height

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or send photos by email with what you know.

Commercial sealant contractors in Hunton: the local picture

Hunton is about 58 miles from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Firms with branches across the South East can use one contractor for every site. Hunton is in the South East, one of the UK’s drier regions. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

For premises near Micheldever station, 2.9 miles north-east of Hunton, footfall is part of the plan: work is phased so shops and offices keep trading. Refits at hotels like Norton Park Hotel, 1.1 miles north-west of Hunton, bring joints at vanity tops, bars and reception desks that guests see every day.

Hunton is about 7 miles north of Winchester, in Hampshire. We cover commercial sites throughout Hunton, whether it’s a single job or part of a planned programme. Across Hampshire, 723 places are covered, including Hunton. Our Southampton page has more on work in that area.

Just outside Hunton, we also work in Stoke Charity (1 mile south-east), Egypt (1 mile west), Sutton Scotney (1 mile west), South Wonston (3 miles south) and Barton Stacey (3 miles west).

What the job involves on each surface

Facade and cladding joints

Facade joints move every day as panels warm and cool. The product has to suit the movement, and the depth has to be controlled with backing. We confirm the access in place before we quote.

Washrooms and toilets

Black sealant in a toilet block is normally beyond cleaning. Replacement is the fix: strip, clean, dry and reseal, room by room if that suits the building.
