Commercial sealant contractors in Hillstreet

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Commercial mastic work in Hillstreet

Getting a price for commercial sealant contractors in Hillstreet doesn’t need to be drawn out. Our quote form takes photographs, drawings or a schedule of the areas. If the joints need seeing in person, a site visit comes first. Site teams most often ask us about window and door perimeter joints that have cracked open and mouldy silicone around WCs, urinals and vanity tops, on movement joints in walls and floors, washrooms and tea points and external facade joints. Facilities teams, main contractors and managing agents in Hillstreet tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In Hillstreet, as anywhere, the first joints to go are normally the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

Business units in the countryside around places like Hillstreet are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Owners, agents and contractors

When you manage a building on behalf of an owner, 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.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Hillstreet can sit alongside others in a wider programme across Hampshire.

On site: what to expect

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For work around Hillstreet, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. First, details reach us through the quote form or a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  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

  • For older buildings, check the asbestos register before work
  • Warn occupants and staff about the work
  • Tell us your opening times and when work is allowed

Ask for a quote

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to call the office on 01277 525 020 or email us.

What sets the cost

Quotes vary with the job. It mainly depends on:

  • Induction, permit and paperwork requirements
  • Phasing around occupants
  • Quantities, in metres or numbers
  • How accessible the joints are

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What to include in your enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • Specification clauses that apply
  • Asbestos survey details if the building is older
  • The site address and postcode
  • Clear photographs of the problem areas

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • A failed roof covering or waterproofing membrane
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Cracking that needs a structural engineer to look at it

If in doubt, call the office on 01277 525 020 or email drawings and photos and we will say what we think before you book.

What we seal

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

Should maintenance staff do it?

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 where general trades tend to cut corners.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Sealant on show in Hillstreet’s commercial buildings

Hillstreet sits close to the coast, within about 3 miles. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. A matched colour is only half the brief on an exposed frontage. Rainfall across the South East, Hillstreet included, is lower than in many parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up.

Shops and cafés around stations like Totton station, 2.3 miles to the south-east of Hillstreet, trade from early, so work is timed around them. Units at places like Nursling Retail Park (1.8 miles east of Hillstreet) are refitted as brands change, and the joints have to suit each new scheme. Industrial estates such as South Hampshire Industrial Park, 0.8 miles to the south-east of Hillstreet, have offices, trade counters and welfare areas whose sealant ages like any other building’s.

Hillstreet is about 2 miles north of Totton, in Hampshire. Looking for commercial sealant contractors in Hillstreet? We can help, as we do across Hampshire. We work across 723 places in Hampshire. We also cover Southampton, some 6 miles away.

Questions we are asked in Hillstreet

Can you work at a site such as South Hampshire Industrial Park, by Hillstreet?

Yes. We cover Hillstreet and the area around it, including industrial estates, business parks and retail parks such as South Hampshire Industrial Park. To start, just ring 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Can being near the sea in Hillstreet affect the sealant we need?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Do you work in Hillstreet?

Yes. We take on work across Hillstreet.

Is the old sealant taken out first?

Every scrap of failed sealant is removed before the new bead goes on. Sealing over traps water and lifts once the joint moves, so it isn’t something we do.

What guarantee do you give on resealing?

Our workmanship is guaranteed for 12 months. We’re fully insured for public liability as well.

Do you work directly for building managers?

Yes. FMs, managing agents and landlords are among our regular clients. We can work to your instruction process and site rules.

Keeping the joints sound

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

  • Keep barriers up until the new sealant has cured
  • Keep a record of which joints were resealed and when
  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Keep washroom and kitchen extraction working

Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life; a mild cleaner is all most joints need.

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.
