About our commercial sealant contractors in Foxbury

A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed, then both faces are cleaned back to sound, dry material with no dust or grease on them. Primer is used wherever the manufacturer calls for it on that surface, and a backing rod limits the depth to give the sealant room to work. If you are dealing with weathered facade sealant that no longer flexes and frame mastic that has hardened and come away from the wall, we can help, whatever the surface. One point of contact handles commercial sealant work in Foxbury from the first photographs to the final walk-round, whether it’s one building or several.

In Foxbury, as anywhere, the first joints to go are typically the ones that work hardest: south-facing perimeters, entrance thresholds and busy washrooms.

For managing agents and FMs looking after premises in Foxbury, access is typically the first question: loading bay slots, goods lifts, permits to work and somewhere to keep materials. With access agreed, we work through the sealant joints a section at a time, keeping disruption to tenants low.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

FAQs: Foxbury

Do hotels near Foxbury have to close for sealant work?

Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we’ll plan around them.

Is Crayfields Business Park, near Foxbury, within your area?

Yes. Our area takes in Foxbury and its surroundings, with estates and business parks such as Crayfields Business Park included. To start, just phone 01277 525 020 or email us with the unit, the joints involved and your access times.

Is Foxbury in your area?

Yes. We take on work across Foxbury, and the same phone number covers every area.

How do you keep disruption to occupiers down?

Most of the buildings we work in stay occupied. Only the area being sealed is closed, and the sequence is agreed in advance for as long as the cure needs.

Does commercial sealant work come with a guarantee?

It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

From enquiry to sign-off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. First, details reach us through the quote form or a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Where parts of the building must stay open, the work is phased.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

What we need from you

  • Tell us which areas need to stay in use
  • Have the specification and drawings to hand
  • Flag any permit to work we’ll need

Ask for a quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or email the details over.

Advice

Shops, offices and hotels in and around Foxbury

Contractor rules in London buildings can be strict, with inductions, permits and timed loading all normal. We plan around them and agree phasing so tenants and clients aren’t disrupted. A 2-mile radius around Foxbury takes in a number of hotels. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet.

If you have premises on more than one site, say at Crayfields Business Park and Green Lane Business Park, one contractor and one quote can cover both. For a job in Foxbury, we confirm the ULEZ-compliant vehicle, the loading arrangements and where materials go before we arrive.

What affects the price in Foxbury

What shapes the price:

  • Any access equipment needed
  • Site requirements such as inductions and permits
  • Travel to remote or island sites
  • Whether the work must be split into stages

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What we need to price the job

Whether it’s one area or a whole building, the same details help:

  • Drawings or a marked-up plan, if available
  • Any specification or named product
  • Photos of the joints, close up and from further back
  • Where the site is, with the postcode

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. If you have questions first, give us a call on 01277 525 020 or email drawings and photos.

Leave it or put it right?

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. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why us?

  • Clear, fixed quotes
  • Work carried out by CSCS-carded applicators
  • Sealing commercial buildings since 2005
  • CHAS accredited

Take a look at what affects the cost and our accreditations.

Doing it in-house

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

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 sealant work can’t fix

Honesty saves time and money. New sealant won’t cure:

  • Broken glass or blown double-glazed units
  • Cracking that needs a structural engineer to look at it
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)

If you’re not sure, just phone 01277 525 020 or use the quote form and we will give you a straight answer before you book.

Surfaces we seal

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

Common problems we fix in Foxbury

A split down the middle of the bead tells a different story. Usually the movement was too much for the sealant chosen because the bead was too thin, the joint over-stretched or the movement class wrong. The same product in the same joint tends to fail the same way, so width, depth and product are checked before we quote.

Any of the following is a good reason to get the joints checked over:

  • Shrunken sealant along kitchen worktops and splashbacks
  • Frame sealant that has cracked, shrunk or pulled away
  • External beads that have gone brittle and cracked
  • Earlier reseals applied straight onto the failed bead

Offices and shops close to stations such as Sidcup station, 1.2 miles to the north-east of Foxbury, tend to be busy all day, so sealant work is planned around opening hours.

What to look for in a quote

  • The named product and why it was chosen
  • Their plan for phasing and protecting the area
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their pre-qualification and accreditations
