Commercial sealant contractors in Borough Green

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before old sealant is disturbed, since managing asbestos is the dutyholder’s responsibility. Anything suspect is left alone until it has been tested. If you’re dealing with untidy joints in a reception, shop floor or lobby and expansion joints with the sealant torn out, we can put it right, on external facade joints, washrooms and tea points and floor and threshold joints alike. For commercial sealant work in Borough Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In Borough Green, as anywhere, the first joints to go are typically the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

In a smaller place such as Borough Green, commercial buildings are typically a mix of shops, a pub or café, a school, a surgery and perhaps a few business units. They’re not big jobs one by one, but their joints need the same preparation as anywhere.

Every job we finish is backed by a 12-month workmanship guarantee, in Borough Green as everywhere else we work. If our installation lets you down in that time, we return and fix it.

When to call us in Borough Green

In wet areas the enemy is typically mould rather than movement. Constant moisture, cleaning chemicals and weak extraction let mould grow into the sealant. The fix is a new bead of anti-mould sanitary silicone.

Typical triggers for a call:

  • Earlier reseals applied straight onto the failed bead
  • Messy, uneven beads from earlier work that let the building down
  • Shrunken sealant along kitchen worktops and splashbacks
  • Sanitary sealant that has gone black and patchy

Refits at hotels like The Bull Hotel (1.2 miles north of Borough Green) bring joints at vanity tops, bars and reception desks that guests see every day.

How to choose a sealant contractor

On site: what to expect

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Work in places the size of Borough Green is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.

  1. We start with the evidence: photos, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. We agree the order of work, access windows and site hours with you.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  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.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Have the specification and drawings to hand
  • For older buildings, check the asbestos register before work

Owners, agents and contractors

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

What happens if it’s left?

Fixing joints complaint by complaint is a costly way to manage sealant. A planned programme groups work by building or area, cuts repeat visits and gives you a budget figure. We will suggest an order, worst sealant joints first. Small buildings around Borough Green suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

What you get with us

  • Public liability insurance in place
  • A fixed quote before work starts
  • Old sealant cut out, never sealed over
  • Matching to RAL references, product permitting

Questions about Borough Green

Is Borough Green off your patch?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

Does your area include sites such as Bourne Enterprise Centre, near Borough Green?

Yes, sites like Bourne Enterprise Centre are within our area, along with the rest of Borough Green. Photos and a short description are enough for a first look.

Do you work directly for building managers?

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

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Could the old sealant in an older building contain asbestos?

We check the asbestos register or survey before any old sealant is disturbed. The duty to manage asbestos sits with the dutyholder, and we don’t remove asbestos-containing materials.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards.

How the quote is worked out

Before we quote, we look at:

  • Distance, for remote addresses
  • Specialist products, such as fire-rated or hygienic sealants
  • How much existing material needs removing
  • How accessible the joints are

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What we need to price the job

Good information means a firmer quote. Helpful details to send:

  • Any dates the work must fit around
  • Whether an asbestos survey exists
  • Approximate linear metres or a joint schedule
  • The product your specification calls for

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or email us to discuss it first.
