About our commercial sealant contractors in St Ives

Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the paperwork side is in order: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. Let us know which site documents you need and they’ll be confirmed with the quote. We work on washrooms and tea points, window and door perimeters and external facade joints, and the usual reasons a site gets in touch are hardened, chalky sealant on south-facing or exposed elevations and earlier reseals applied straight onto the failed bead. Facilities teams, main contractors and managing agents in St Ives tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Quotes for commercial sealant in St Ives can come from photos and a joint schedule, or from a walk-round, and the scope is set out in writing.

Rural business units near smaller places such as St Ives are frequently converted agricultural buildings. 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.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Your questions answered

Must a hotel around St Ives close while you work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Tell us your quiet periods and access windows and we’ll plan around them.

Is a smaller place like St Ives outside your area?

No. Places such as St Ives are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Can areas stay open during the work?

We phase the work so parts of the building stay open. We plan around the site hours and access windows you give us.

Could the old sealant in an older building contain asbestos?

On older buildings, our first request is the asbestos survey. The duty to manage asbestos sits with the dutyholder, and we don’t remove asbestos-containing materials.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it.

What guarantee do you give on resealing?

Our workmanship on each job is backed by a 12-month guarantee. Public liability insurance is in place too.

On site: what to expect

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. For work around St Ives, 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. We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations, and a site visit is booked where it helps.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Getting the site ready

  • Tell staff and tenants when we will be in
  • Have the specification and drawings to hand
  • Let us know about inductions and permits

Advice

Commercial sealant contractors around St Ives: how the place shapes the job

The 3 miles around St Ives take in at least three named trading estates, business parks or retail parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal, often in a colour the occupier specifies. The 2 miles around St Ives include three care or nursing homes. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound; colours can be chosen to suit the interior.

For a hotel such as St Leonards Hotel, 0.8 miles south-west of St Ives, the colour of a joint at the bar or the bath matters to the look of the room. Industrial estates such as Ashley Heath Industrial Estate (to the north-west of St Ives) have offices, trade counters and welfare areas whose sealant ages like any other building’s. Sites a few miles apart, such as Ashley Heath Industrial Estate and Millstream Trading Estate, can share one programme and one point of contact.

St Ives is in Hampshire. We cover St Ives and the rest of Hampshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Hampshire coverage takes in 723 places, large and small. We also cover Southampton, some 20 miles away.

Surface by surface

Fire-rated seals where specified

Not every penetration suits a sealant. Other products, such as collars, wraps and batts, are specified for different services.

Movement joints in walls and floors

A trafficked floor joint needs a different product from a wall joint. We will recommend the right filler or sealant for the traffic and movement, and tell you if the edges need repairing first.

Why it’s worth doing now in St Ives

Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. In many cases the element is fine and only the seal around it has given up. A careful reseal is a far smaller undertaking than replacement, and we will say so if the frame or fitting is life-expired. Converted and older buildings near places like St Ives tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Why choose Mastic Doctor in St Ives

See how commercial sealant jobs are priced and how we’re accredited.

After the work

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

  • Note dates and locations of sealant work for future planning
  • Don’t let cleaning or traffic back on before the cure time is up
  • Deal with small splits before they become leaks
  • Ask cleaners to use a soft cloth and mild cleaner on sealant

Keep an eye out for other trades after we’ve gone. Shop refits, new services and replaced fittings often break the seal around them and the joint gets left open. If that happens, call 01277 525 020 or email us and we’ll price putting it right.

Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.

How the quote is worked out

Before we quote, we look at:

  • Location, for remote and island sites
  • Specialist products, such as fire-rated or hygienic sealants
  • The total length or number of joints
  • Induction, permit and paperwork requirements

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.

Sending details for a quote

There’s no need for a formal survey. A few details are enough to get going:

  • The type of building and who uses it
  • The product your specification calls for
  • A wide shot and a close-up of the area
  • Whether an asbestos survey exists

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

What we can’t put right

Some faults sit outside our scope, and we say so rather than covering them up:

  • Water from a services leak rather than a joint
  • A failed roof covering or waterproofing membrane
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)

If you’re not sure, just give us a call on 01277 525 020 or use the quote form and we’ll give you a straight answer.
