Commercial sealant contractors for commercial buildings in Gold Street

Sometimes a split bead is a symptom rather than the cause. Water at a window perimeter might be coming from the frame, the cill or the wall behind. We look before we quote and tell you plainly if sealant won’t solve it, so nobody pays for a reseal that can’t hold. If you have external beads that have gone brittle and cracked and leaks that seem to come through a sealant line, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Gold Street it comes down to the same thing: the right product in a properly prepared joint.

If you look after more than one building near Gold Street, the work can be planned as one programme, with one quote format and one point of contact.

Commercial sealant work around smaller places like Gold Street tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Each has kitchens, washrooms and frames whose joints need renewing in time.

We stand by our work with a 12-month guarantee. That covers our preparation and application.

Honest limits

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • Broken glass or blown double-glazed units
  • Walls or slabs moving more than any sealant can take

If you are not sure, just phone 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Surfaces we seal

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

On site: what to expect

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Gold Street are typically planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. First, details come to us: photographs, drawings or a schedule of the areas.
  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. We strip the failed bead and prepare both faces of the joint.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Preparing the site

  • Agree which areas must stay open
  • Clear stock, furniture or equipment away from the joints
  • Send any specification or drawings in advance

Ask for a quote

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, photographs and a description will do.

Gold Street: questions and answers

Is Gold Street off your patch?

Not at all. Gold Street is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will you take on work at estates like Bowes Industrial Centre, close to Gold Street?

Yes, sites like Bowes Industrial Centre are within our area, along with the rest of Gold Street. Photos and a short description are enough for a first look.

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.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can you take on work for an FM or managing agent?

Yes, and through main contractors too. You send the details, we return a fixed quote, and the job is done and signed off, with a 12-month guarantee on the workmanship.

Could the old sealant in an older building contain asbestos?

Some older mastics did contain asbestos. So we check the register first and stop work on anything suspect until it’s tested.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

What we’re called out for in Gold Street

Outside, sunlight and rain wear sealant down year after year. Sunny elevations dry the surface out and exposed ones take driving rain. A hardened bead can’t follow the building any more.

Clients normally get in touch after noticing one or more of the following:

  • Mouldy silicone around WCs, urinals and vanity tops
  • Earlier reseals applied straight onto the failed bead
  • Weathered facade sealant that no longer flexes
  • Smeared sealant across finishes from a rushed job

A unit on an estate like Bowes Industrial Centre, 2.2 miles south-west of Gold Street, normally has an office front, a trade counter and staff facilities with joints of their own.

What to look for in a quote

  • Are they CHAS accredited or on Constructionline?
  • How the existing material will be dealt with
  • How long is the guarantee, and what does it include?
  • What level of public liability insurance do they hold?

What the job involves on each surface

Shop fronts and retail fit-outs

Retail work normally has to fit around trading. We plan around the access windows the store gives us.

Commercial kitchens and tea points

Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. They’re degreased thoroughly before resealing, and a hygienic or food-safe sealant is used where food contact is possible.
