Commercial sealant contractors near Potters Corner

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

On site: what to expect

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 any cutting starts, and the work typically takes a few hours to several days on most single sites, depending on joint lengths and access. Smaller jobs around Potters Corner can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. Site photos, 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. We agree the order of work, access windows and site hours with you.
  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. We hand back each area with its cure time and our 12-month guarantee.

Getting the site ready

  • Let building users know which areas are affected
  • Share the asbestos register for older buildings
  • Have the specification and drawings to hand

Sealant applicators in Potters Corner

Failed sealant isn’t always the whole story. A leak near a frame edge can start in the frame, the cill or the cavity, and repeated splits in a movement joint can mean the joint is too narrow for the movement. Part of the job is telling you when the fix is something other than sealant, so nobody pays for a reseal that can’t hold. Site teams most often ask us about damp patches where an external joint has failed and black mould through washroom sealant that won’t clean off, on kitchen worktops and splashbacks, window and door perimeters and floor and threshold joints. A specialist sealant contractor works differently from a general builder: in Potters Corner, that means joint design, primers and backing rod as standard.

Occupied buildings in Potters Corner need the work phased: we agree the order with you and hand back each area with its cure time.

Commercial sealant work around smaller places like Potters Corner 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.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. 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.

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.

Common problems we fix in Potters Corner

Resealing over the top is a false economy we come across often. New silicone has nothing to key into so it soon peels and traps moisture against the joint. By the time it shows, there can be two or three layers to cut out.

Common reasons buildings call us in:

  • Greasy, split joints in a kitchen or tea point
  • Earlier reseals applied straight onto the failed bead
  • Damp patches where an external joint has failed
  • Movement joints packed with grit and debris

On a business park such as Eurogate Business Park, 0.9 miles to the south-east of Potters Corner, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.

What to look for in a quote

  • What the guarantee covers, and for how long
  • Whether primer will be used where the manufacturer specifies it
  • Their plan for phasing and protecting the area
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Choosing a commercial sealant contractor

How the quote is worked out

We price every job individually. The things that drive the figure:

  • The total length or number of joints
  • Specialist products, such as fire-rated or hygienic sealants
  • Backing rod, priming and other preparation
  • Any access equipment needed

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you are ready.

Details that help us quote

However big the job, the same details help:

  • Where the site is, with the postcode
  • Asbestos survey details if the building is older
  • Clear photos of the problem areas
  • Any specification or named product

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Questions about Potters Corner

Do you cover business parks and estates near Potters Corner, such as Eurogate Business Park?

Yes, sites like Eurogate Business Park are within our area, along with the rest of Potters Corner. A few photographs and the unit address let us price the work.

Is Potters Corner too far out for you?

Not at all: smaller places are covered as well as towns. 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 you hold CHAS accreditation?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Can areas stay open during the work?

Most of the buildings we work in stay occupied. We agree the order of areas, protect what’s nearby and close off only the section we’re sealing.

What about asbestos in old mastic?

It’s possible in older buildings, especially those built before 2000. We ask to see the asbestos register or survey before disturbing old sealant, and anything suspect is left until it has been tested.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

Is it OK to apply fresh sealant over existing beads?

Removal of the failed sealant is always part of the job. Laying new silicone on old gives it nothing to grip, and the faces are brought back to sound, dry material before resealing.

Work for main contractors and building owners

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

What sealant work can’t fix

We check first that sealant really is the fix. It isn’t the answer for:

  • Suspect materials that need testing and specialist removal
  • A failed roof covering or waterproofing membrane
  • Structural cracks or movement the joints weren’t designed for

Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly before you book.

What we seal

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