About our commercial sealant contractors in Long Sutton

Sealant joints are easy to overlook until one lets water in. We are commercial sealant applicators for FMs, managing agents, landlords and contractors. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. Most enquiries involve hardened, chalky sealant on south-facing or exposed elevations and movement joints packed with grit and debris, across washrooms and tea points, movement joints in walls and floors and kitchen worktops and splashbacks. Looking for mastic applicators who cover Long Sutton? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

A lot of what we do in Long Sutton is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Work in smaller places such as Long Sutton tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What the job involves on each surface

Movement joints in walls and floors

A trafficked floor joint needs a different product from a wall joint. The choice comes down to how much the joint moves and what runs over it; if the arrises are broken, we’ll say so before sealing.

Facade and cladding joints

Facade joints move every day as panels warm and cool. They need a sealant with the right movement capability, laid at the right depth. We confirm the access in place before we quote.

What we’re called out for in Long Sutton

When a bead peels cleanly off one face, it has failed in adhesion. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. We see it often where joints were sealed in a hurry.

Clients normally get in touch after noticing something like this:

  • Window and door perimeter joints that have cracked open
  • Gaps behind commercial kitchen worktops and sinks
  • Weathered facade sealant that no longer flexes
  • Layers of sealant, all of them failing

A lasting commercial joint around Long Sutton begins with the old bead fully out and the faces clean and dry.

Questions to ask before you book

  • Will RAMS and insurance details be available?
  • How they’ll work around occupants
  • Whether primer will be used where the manufacturer specifies it
  • How long is the guarantee, and what does it include?

Our contractor checklist

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Cracking that needs a structural engineer to look at it
  • Suspect materials that need testing and specialist removal
  • A failed roof covering or waterproofing membrane

If you’re not sure, just speak to us on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Long Sutton: questions and answers

Is a smaller place like Long Sutton outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can you supply sealant in our brand colour for a site in Long Sutton?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Send colour references or photos and we’ll confirm what’s available for the product.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Do you work for facilities managers and managing agents?

Yes. Use our quote form to send the site details, or phone or email us, and tell us what site paperwork you need.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

What happens if it’s left?

Spot repairs have their place. If the rest of the bead is the same age and product, though, it’s typically close behind, and a second visit means paying for access and set-up again. We can price both options so you can decide on the facts. Converted and older buildings near places like Long Sutton tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

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

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a few hours to several days on most single sites, depending on joint lengths and access, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Long Sutton are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. Site photographs, drawings or a visit tell us what’s there and how it has failed.
  2. A fixed quote follows, with removal and preparation included.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. Completed areas are signed off with you under our 12-month guarantee.

Preparing the site

  • Arrange parking or a loading space
  • Tell us which areas need to stay in use
  • Flag any permit to work we’ll need
