Commercial sealant contractors in Stonebridge Green

How long a joint lasts is decided before any sealant leaves the gun. Silicone has no grip on cured silicone, so the failed bead is cut out completely. Primer is used wherever the manufacturer calls for it on that surface. We work on external facade joints, floor and threshold joints and kitchen worktops and splashbacks, and the failures we are asked to look at most are external beads that have gone brittle and cracked and black mould through washroom sealant that won’t clean off. A specialist sealant contractor works differently from a general builder: on jobs in Stonebridge Green, preparation and product choice get the time they need.

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

Business units in the countryside around places like Stonebridge Green are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Our process

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking a few hours to several days on most single sites, depending on joint lengths and access. Jobs in and around smaller places like Stonebridge Green are normally planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations.
  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. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Before we start on site

  • Confirm the product named in the specification
  • Flag any permit to work we’ll need
  • Let building users know which areas are affected

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Advice

Looking after the joints

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

  • Keep abrasive pads and scrapers off resealed joints
  • Keep washroom and kitchen extraction working
  • Deal with small splits before they become leaks
  • Note dates and locations of sealant work for future planning

Good ventilation keeps wet-area sealant in better condition. Fans that are broken or switched off leave joints damp for longer. It’s worth having fans checked while the sealant is fresh.

Sealant rarely fails all at once across a building. A few splits this year typically mean more next year so the whole run is worth inspecting. We’ll tell you which sealant joints need doing first and which can wait.

Your questions answered

Is a smaller place like Stonebridge Green outside your area?

No. Small places get the same service as large ones. 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.

Do hotels near Stonebridge Green have to close for sealant work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.

Do you check for asbestos before removing sealant?

We check the asbestos register or survey before any old sealant is disturbed. The duty to manage asbestos sits with the dutyholder.

Does commercial sealant work come with a guarantee?

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

Which site documents can you send us?

Send your site requirements with the enquiry. For older buildings we will ask for the asbestos register, plus your site induction rules.

Is the old sealant taken out first?

Removal of the failed sealant is always part of the job. New sealant can’t grip the old bead, so laying over it never lasts.

Can areas stay open during the work?

That comes down to planning: we agree access windows, phase the work and keep enough facilities open. Let us know what can’t close and we will work around it.

What sets the cost

What shapes the price:

  • How much existing material needs removing
  • The product specified
  • Backing rod, priming and other preparation
  • How accessible the joints are

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.

Before you send an enquiry

A good diagnosis starts with the right details. Let us know:

  • Any dates the work must fit around
  • What the building is and how it’s used
  • The site address and postcode
  • Whether an asbestos survey exists

Different surfaces, different methods

Movement joints in walls and floors

Floor joints that take trolleys or forklifts need a tougher filler or sealant. We will recommend the right filler or sealant for the traffic and movement.

Window and door perimeters

Inside, cracked sealant around frames and window boards is common. The product depends on whether the joint will be painted, matched to the frame colour where colour matters.

What happens if it’s left?

On many buildings the mastic was done by whichever trade was on site. Choosing the product, setting the depth and preparing the faces are what a specialist brings. You notice the difference years later, not on the day. For buildings around smaller places like Stonebridge Green, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Why us?

  • Colour options checked against the specified product
  • Constructionline member for supplier checks
  • Over 20 years of commercial sealing
  • Fully insured, including public liability cover

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
